ABSTRACT

Lonicerae Japonicae Flos, as common Chinese medicine, has been used for thousands of years in the treatment of inflammation and infectious diseases with definite efficacies. The complex composition of Lonicerae Japonicae Flos results in its extensive pharmacological effects, so the assessment of its quality by only a few index components is not comprehensive. Guided by the quality marker(Q-marker), the present study comprehensively analyzed and predicted the quality connotation of Lonicerae Japonicae Flos based on the chemical composition and component transfer, the phylogenetic relationship, chemical composition effectiveness, measurability, and specificity. Chlorogenic acid, isochlorogenic acids A, B, and C, luteoloside, rutin, sweroside, and secoxyloganin were predicted as candidate Q-markers of Lonicerae Japonicae Flos.

ABSTRACT

This study aims to develop an HPLC-DAD method for simultaneous determination of 11 components(6 phenolic acids and 5 iridoids) in Lonicera japonica flowers(LjF) and leaves(LjL), and compare the content differences of LjF at different development stages, LjL at different maturity levels, and between LjF and LjL. One-way ANOVA, principal component analysis(PCA), and orthogonal partial least-squares discriminant analysis(OPLS-DA) were employed to compare the content of the 11 components. The content of total phenolic acids, total iridoid glycosides, and total 11 components in LjF showed an overall downward trend with the development of flowers. The content of total phenolic acids, total iridoid glycosides, and total 11 components in young leaves were higher than those in mature leaves. The results of PCA showed that the samples at different flowering stages had distinguishable differences in component content. The VIP value of OPLS-DA showed that isochlorogenic acid A, chlorogenic acid, and secologanic acid were the main differential components of LjF at different development stages or LjL with different maturity levels. LjF and LjL have certain similarities in chemical composition while significant differences in component content. The content of total phenolic acids in young leaves was significantly higher than that in LjF at various development stages. The content of total iridoid glycosides in young leaves was similar to that in LjF before white flower bud stage. The total content of 11 components in young leaves was significantly higher than that in LjF at green flower bud stage, before and during completely white flower bud stage. LjL have great potential for development. Follow-up research on the pharmacodynamic equivalence of LjF and LjL(especially young leaves) should be carried out to speed up the development and application of LjL.

ABSTRACT

In order to explore the functions of genes of key rate-limiting enzymes chalcone isomerase(CHI) and chalcone synthase(CHS) in the biosynthesis of flavonoids in Lonicera macranthoides, this study screened and cloned the cDNA sequences of CHI and CHS genes from the transcriptome data of conventional variety and 'Xianglei' of L. macranthoides. Online bioinformatics analysis software was used to analyze the characteristics of the encoded proteins, and quantitative reverse-transcription polymerase chain reaction(qRT-PCR) to detect the expression of CHI and CHS in different parts of the varieties at different flowering stages. The content of luteo-loside was determined by high performance liquid chromatography(HPLC) and the correlation with the expression of the two genes was analyzed. The results showed that the CHI and CHS of the two varieties contained a 627 bp and 1170 bp open reading frame(ORF), respectively, and the CHI protein and CHS protein were stable, hydrophilic, and non-secretory. qRT-PCR results demonstrated that CHI and CHS of the two varieties were differentially expressed in stems and leaves at different flowering stages, particularly the key stages. Based on HPLC data, luteoloside content was in negative correlation with the relative expression of the genes. Thus, CHI and CHS might regulate the accumulation of flavonoids in L. macranthoides, and the specific functions should be further studied. This study cloned CHI and CHS in L. macranthoides and analyzed their expression for the first time, which laid a basis for investigating the molecular mechanism of the differences in flavonoids such as luteoloside in L. macranthoides and variety breeding.

ABSTRACT

Lonicera Japonica Flos is the dried bud or nascent flower of Lonicera japonica(Caprifoliaceae). The plant suffers from various diseases and pests in the growth period and thus pesticides are often used. As a result, the resultant pesticide residues in Lonicera Japonica Flos have aroused great concern. This review summarized the investigation, detection methods, content analysis, and risk assessment of pesticide residues in Lonicera Japonica Flos since 1996, and compared the maximum residue limits among different countries and regions. The results showed that the pesticide residues were detected in Lonicera Japonica Flos from different production areas, and only some exceeded the limits. The residual pesticides have changed from organochlorines to new types such as tebuconazole and nitenpyram. The detection method has upgraded from chromatography to chromatography-mass spectrometry. Most pesticide residues will not cause health risks, except carbofuran. Pesticide residues limit the development of Lonicera Japonica Flos industry in China. In practice, we should improve the drug registration of Lonicera Japonica Flos, promote ecological prevention and control technology, and formulate and promote pesticide residue limit standard of Lonicera Japonica Flos.

ABSTRACT

The present study optimized the extraction of flavonoids from Lonicera rupicola Hook. f. et Thoms(LRH) and explored its pharmacological effects, such as resisting inflammation, relieving pain, enhancing immunity, and inhibiting pyroptosis, aiming to provide data support and scientific basis for the development and utilization of LRH. Response surface methodology(RSM) was applied to optimize the extraction of flavonoids from LRH based on the results of single-factor experiments. Anti-inflammatory and analgesic effects of LRH flavonoids were evaluated via inflammation and pain models in mice, such as xylene-induced ear swelling, carrageenan-induced footpad swelling, writhing caused by acetic acid, and paw licking. The effect of LRH flavonoids on the carbon clearance index of monocytes and serum immunoglobulin A(IgA) and IgM levels was analyzed on the immunosuppression model induced by cyclophosphamide in mice. The anti-oxidative effect in vivo of LRH flavonoids on liver superoxide dismutase(SOD), catalase(CAT), and malondialdehyde(MDA) levels was determined based on the chronic/subacute aging model in mice induced by D-galactose. The levels of cysteinyl aspartate specific proteinase-1(caspase-1), interleukin-1β(IL-1β), and IL-18 in the supernatant of J774 A.1 mononuclear phagocytes were detected to evaluate the effect of LRH flavonoids on the pyroptosis of mononuclear phagocytes in mice induced by the combination of lipopolysaccharide(LPS) and adenosine triphosphate(ATP). Meanwhile, the effect of LRH flavonoids on the cAMP-PKA signaling pathway was also explored. The optimum conditions for the extraction of LRH flavonoids are listed below: extraction temperature of 65 ℃, the ethanol concentration of 50%, extraction time of 60 min, a material-liquid ratio at 1∶25, and the yield of LRH flavonoids of 0.553%. RSM determined the multiple quadratic regression equation model of response value and variables as follows: the yield of LRH flavonoids=0.61-0.48A+0.1B+0.029C-0.014D+0.32AB+0.04AC-0.012AD-0.02BC+0.037BD-0.031CD-0.058A~2-0.068B~2-0.069C~2-0.057D~2. LRH flavonoids could effectively inhibit ear swelling and footpad swelling, reduced acetic acid-induced writhing, and delayed the paw licking response time in mice. Additionally, LRH flavonoids could improve the carbon clearance index in immunosuppressed mice, potentiate the activities of SOD and CAT and reduce MDA levels in the liver of aging mice induced by D-galactose, and effectively inhibit macrophage pyroptosis by decreasing the levels of caspase-1, IL-1β, and IL-18. The results reveal that LRH flavonoids possess excellent pharmacological activities such as resisting inflammation and oxidation, relieving pain, and enhancing immunity. They can inhibit pyroptosis by enhancing the cAMP-PKA signaling pathway. The results of this study can underpin the pharmacological research, development, and utilization of LRH.

ABSTRACT

In order to study the regulation mechanism of secondary metabolites biosynthesis in Lonicera macranthoides, the key genes involved in the regulation of biosynthesis and the mechanism of differential metabolites were explored. In this study, high-throughput sequencing technology was used for transcriptome sequencing of L. macranthoides at different development stages. By using Liquid chromatography-tandem mass spectrometry(LC-MS/MS) technology, the laws of qualitative, quantitative and synthetic accumulation of its metabolites were studied, and the key enzyme genes for the biosynthesis of phenolic acid and flavonoids were screened out according to the differentially expressed genes. A total of 111 differentially accumulate metabolites(DAM) and 6 653 differentially expressed genes(DGE) were obtained by metabonomics and transcriptomics analysis. The metabolites and key enzyme genes in the Erqing(KE) were significantly different from those in the Dabai(KD) and Yinhua(KY) stages. In the phenylalanine biosynthesis pathway, the ion abundance of chlorogenic acid, naringin, quercetin, rutin, coniferol and other metabolites decreased with the development of flowers, while the ion abundance of ferulic acid, coumarin and syringoside increased with the development of flowers. Key enzyme genes such as CHS, HCT, CCR, FLS and COMT positively regulate the downstream metabolites, while PAL, C4H and 4CL negatively regulate the downstream metabolites. This study provides candidate genes and theoretical basis for the further exploration of key enzymes in the biosynthesis of secondary metabolites and for the regulation of the accumulation of secondary metabolites in L. macranthoides by molecular biological methods.

ABSTRACT

As a traditional Chinese medicinal material, Lonicera japonica has a long medicinal history. The chemical constituents of Lonicera japonica are complex, mainly including iridoid glycosides, flavonoids, triterpenes, organic acids and volatile oil. Iridoid glycosides account for a higher proportion. In addition, modern pharmacological studies have shown that the iridoid glycosides have many pharmacological activities such as antivirus, anti-inflammation, anti-tumor, liver protection and lowering blood sugar. This review intends to systematically summarize the iridoid glycosides identified from Lonicera japonica and their pharmacological activities by searc-hing Chinese and English databases, in order to provide a reference for the further development and utilization of Lonicera japonica and for the improvement of quality standards of medicinal materials.

ABSTRACT

A new method of MS/MS~(ALL) was designed to sequentially record a MS~2 spectrum at each unit mass window through gas phase fractionation concept, so as to offer an opportunity for universal MS~2 spectral recording with direct infusion(DI). As a proof-of-concept, DI-MS/MS~(ALL) was applied for rapid chemome profiling of a famous herbal medicine named Lonicerae Japonicae Flos. After each MS~2 spectrum was correlated to its precursor ion, the structural annotation was conducted by applying well-defined mass cracking rules, matching the mass spectral data with literatures and referring to those accessible databases. As a result, a total of 54 components were identified from Lonicerae Japonicae Flos extract, including 21 phenolic acids, 13 flavonoids, 12 iridoids, 4 triterpenoids and 4 other compounds. Therefore, DI-MS/MS~(ALL) is a powerful tool for comprehensive, rapid qualitative analysis of chemical profiles of traditional Chinese medicine and other chemical components of complex systems.

ABSTRACT

Lonicerae Japonicae Flos has a long history of heat-clearing and detoxifying effect. The description of its efficacy in Chinese Pharmacopoeia of past dynasties is relatively stable, and it is an excellent carrier for the study of efficacy markers. Guided by the theory of systematic traditional Chinese medicine, heat-clearing and detoxifying effect efficacy system of Lonicerae Japonicae Flos was taken as an example in this study to clarify the elements(active ingredients) of Lonicerae Japonicae Flos in heat-clearing and detoxifying efficacy system, determine the boundary(signal pathway), establish the structure(system dynamics model), identify the system functions corresponding to pharmacology, efficacy and effects(heat-clearing and detoxifying effect), and explore the application of system dynamics model in the discovery of efficacy markers of traditional Chinese medicine. In this paper, the dynamic models of interleukin 1(IL-1) and interleukin 6(IL-6) in vivo were established to predict the expression of related factors in IL-1 and IL-6 signaling pathways of different components and their combinations in Lonicerae Japonicae Flos by dynamic network, so as to find the effective markers of heat-clearing and detoxification of Lonicerae Japonicae Flos. The results showed that the lower the concentration of chlorogenic acid, the higher the inhibition rate of Jun N-terminal kinase(JNK) at downstream of IL-1 by the combination of chlorogenic acid and linalool; the higher the concentration of luteolin in IL-6 pathway, the higher the inhibition rate of C-reactive protein(CRP) at downstream of IL-6 by the combination of chlorogenic acid and luteolin. It revealed that the potential efficacy markers of Lonicerae Japonicae Flos in heat-clearing and detoxifying effect based on IL-1 signaling pathway were chlorogenic acid and linalool, and the potential efficacy markers of Lonicerae Japonicae Flos in heat-clearing and detoxifying effect based on IL-6 signaling pathway were chlorogenic acid and luteolin. This study provided methodological guidance for the discovery of efficacy markers of traditional Chinese medicine.

ABSTRACT

The aim of this paper was to observe the anti-inflammatory action and mechanism of Lonicerae Japonicae Flos extract and Lonicerae Flos extract in xylene-induced ear swelling experiment and lipopolysaccharide(LPS)-induced RAW264.7 cell inflammatory model. In vivo, xylene-induced mouse auricle swelling model was used to detect the auricle swelling degree and swelling inhibition rate of Lonicerae Japonicae Flos extract and Lonicerae Flos extract; the pathological changes of mice auricle were observed by hematoxylin eosin(HE) staining. In vitro, RAW264.7 inflammatory cell model was induced by LPS, where the cytotoxic effects of Lonicerae Japonicae Flos extract and Lonicerae Flos extract on RAW264.7 cells were detected by CCK-8 method; Griess method was used to detect the effect of Lonicerae Japonicae Flos extract and Lonicerae Flos extract on nitric oxide(NO) production, and ELISA method was used to detect the content of inflammatory factors interleukin-6(IL-6), IL-1β, and tumor necrosis factor-α(TNF-α). At last, Western blot was used to detect the protein changes of cyclooxygenase 1(COX1), COX2 and inducible nitric oxide synthetase(iNOS) for RAW264.7 cells. The results showed that both Lonicerae Japonicae Flos extract and Lonicerae Flos extract could significantly inhibit the degree of auricle swelling caused by xylene in mice and the inhibition rate was positively correlated with the drug dose. Furthermore, both of them could reduce the infiltration of lymphocytes and neutrophils in mouse ear tissues. For in vitro experiments, both Lonicerae Japonicae Flos extract and Lonicerae Flos extract inhibited NO secretion in RAW264.7 cells, down-regulated the release of IL-1β, IL-6 and TNF-α, and down-regulated iNOS protein and COX2, NF-κB p65 protein content. In conclusion, both Lonicerae Japonicae Flos extract and Lonicerae Flos extract have good anti-inflammatory effect, and the mechanism may be related with the inhibition of NF-κB signaling pathway.

ABSTRACT

Taking Lonicerae Japonicae Flos as an example, the method of "expert consensus of different regions" was used to screen the representative samples and evaluate their commodity grades. The correlation analysis, hierarchical cluster analysis and partial least squares discriminant analysis(PLS-DA) of "commodity grade-appearance characteristic-component content" were carried out to reveal the scientificity of traditional commodity grade of Chinese medicinal material. By referring to the existing literature and the grade investigation from the sample collection regions, 78 "initial grade" samples were screened out from 118 collected samples. Authoritative experts from four regions(n=4) including Linyi(Shangdong province), Bozhou(Anhui province), Anguo(Hebei province) and Beijing were organized to evaluate their commodity grades, separately. Based on the grade consistency rate(R_i≥70%), 69 "local grade" samples were screened out from the "initial grade" samples. Based on the average grade consistency rate ■ "authoritative grade" samples were screened out from the "local grade" samples, including15 first-grade samples, 9 second-grade samples, 11 third-grade samples and 17 fourth-grade samples. For these "authoritative grade" samples, the main appea-rance characteristics were quantified and the contents of 13 components were determined by ultra performance liquid chromatography(UPLC). Furthermore, the total contents of 6 phenolic acids, 4 flavonoids and 3 iridoids were calculated, respectively. The results of correlation analysis showed that 4 appearance characteristics indices were correlated with the commodity grades: color, rate of yellow bars(including blooming flowers), rate of black heads(including black bars), and rate of stems and leaves(including bud debris). Five component content indices were correlated with the commodity grades: chlorogenic acid, isochlorogenic acid C, sweroside, loganin and the total contents of six phenolic acids. Furthermore, chlorogenic acid, loganin and the total contents of six phenolic acids showed significantly negative correlation with the main appearance characteristics, indicating that the appearance characteristics of Lonicerae Japonicae Flos can reflect its internal quality, and these 3 indices can be used as quality markers(Q-markers). The results of hierarchical cluster analysis showed that the samples of four grades were classified into four categories, and the samples with the same grades and the same categories accounted for 80.8% of the total samples, while the samples with the different grades were obviously classified into different categories. The results of PLS-DA analysis showed that the samples of different grades showed obvious intragroup aggregation and intergroup dispersion. The above results indicated that it was feasible to evaluate the traditional commodity grade of Lonicerae Japonicae Flos by the method of "expert consensus of different regions". For the evaluation of traditional commodity grade of Chinese medicinal material, the samples should be representative, expert conclusions should have enough consensuses, and grade determination should be authoritative. As the crystallization of clinical experience, traditional commodity grade can scientifically reflect the internal quality of Chinese medicinal material.

ABSTRACT

Identification of Chinese medicinal materials is a fundamental part and an important premise of the modern Chinese medicinal materials industry. As for the traditional Chinese medicinal materials that imitate wild cultivation, due to their scattered, irregular, and fine-grained planting characteristics, the fine classification using traditional classification methods is not accurate. Therefore, a deep convolution neural network model is used for imitating wild planting. Identification of Chinese herbal medicines. This study takes Lonicera japonica remote sensing recognition as an example, and proposes a method for fine classification of L. japonica based on a deep convolutional neural network model. The GoogLeNet network model is used to learn a large number of training samples to extract L. japonica characteristics from drone remote sensing images. Parameters, further optimize the network structure, and obtain a L. japonica recognition model. The research results show that the deep convolutional neural network based on GoogLeNet can effectively extract the L. japonica information that is relatively fragmented in the image, and realize the fine classification of L. japonica. After training and optimization, the overall classification accuracy of L. japonica can reach 97.5%, and total area accuracy is 94.6%, which can provide a reference for the application of deep convolutional neural network method in remote sensing classification of Chinese medicinal materials.

ABSTRACT

PURPOSE: Obesity is a major health problem of global significance because it is clearly associated with an increased risk of health problems, such as nonalcoholic fatty liver disease (NAFLD), diabetes, cardiovascular diseases, and cancer. Lonicera caerulea (LC) originates from high mountains or wet areas and has been used as a traditional medicine in northern Russia, China, and Japan. LC contains a range of bioactive constituents, such as vitamins, minerals, and polyphenols. This study examined the anti-obesity effects of LC during differentiation in preadipocytes. METHODS: The cell viability assay was performed after the differentiation of 3T3-L1 cells for 7 days. Oil Red O staining was used to visualize the changes in lipid droplets in 3T3-L1 cells and mouse adipose-derived stem cells (MADSCs). The mRNA expression of obesity-related genes was determined by quantitative real-time PCR. RESULTS: According to the results of Oil Red O staining, the lipid levels and size of lipid droplets in the adipocytes were reduced and the LC extract (LCE, 0.25–1 mg/mL) markedly inhibited adipogenesis in a dose-dependent manner. The treatment of LCE also decreased the mRNA expression of peroxisome proliferator-activated receptor γ (PPARγ), CCAAT/enhancer binding protein-α (C/EBPα), and sterol regulatory element binding protein 1 (SREBP1) in 3T3-L1 cells. Western blot analysis showed that the PPARγ, C/EBPα, and SREBP1 protein levels in both 3T3-L1 and MADSC were reduced in a dose-dependent manner. CONCLUSION: These results suggest that LCE can inhibit adipogenic differentiation through the regulation of adipogenesis-related markers.

ABSTRACT

We investigated the anti-inflammatory effect of Pyunkang-tang extract (PGT), a complex herbal extract based on traditional Chinese medicine that is used in Korea for controlling diverse pulmonary diseases, on cigarette smoke-induced pulmonary pathology in a rat model of chronic obstructive pulmonary disease (COPD). The constituents of PGT were Lonicerae japonica, Liriope platyphylla, Adenophora triphilla, Xantium strumarinum, Selaginella tamariscina and Rehmannia glutinosa. Rats were exposed by inhalation to a mixture of cigarette smoke extract (CSE) and sulfur dioxide for three weeks to induce COPD-like pulmonary inflammation. PGT was administered orally to rats and pathological changes to the pulmonary system were examined in each group of animals through measurement of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) levels in bronchoalveolar lavage fluid (BALF) at 21 days post-CSE treatment. The effect of PGT on the hypersecretion of pulmonary mucin in rats was assessed by quantification of the amount of mucus secreted and by examining histopathologic changes in tracheal epithelium. Confluent NCI-H292 cells were pretreated with PGT for 30 min and then stimulated with CSE plus PMA (phorbol 12-myristate 13-acetate), for 24 h. The MUC5AC mucin gene expression was measured by RT-PCR. Production of MUC5AC mucin protein was measured by ELISA. The results were as follows: (1) PGT inhibited CSE-induced pulmonary inflammation as shown by decreased TNF-α and IL-6 levels in BALF; (2) PGT inhibited the hypersecretion of pulmonary mucin and normalized the increased amount of mucosubstances in goblet cells of the CSE-induced COPD rat model; (3) PGT inhibited CSE-induced MUC5AC mucin production and gene expression in vitro in NCI-H292 cells, a human airway epithelial cell line. These results suggest that PGT might regulate the inflammatory aspects of COPD in a rat model.

ABSTRACT

The flower buds of Lonicera macranthoides (Shan Yin-Hua), represent an important traditional Chinese medicine and food ingredient. A phytochemical investigation of the 70% EtOH extract of the flower buds of L. macranthoides resulted in the isolation of 12 triterpenoids (1-12), including two new ursane-type nortriterpenes, 2α, 24-dihydroxy-23-nor-ursolic acid (1) and 2α, 4α-dihydroxy-23-nor-ursolic acid (2). Their structures were established by multiple spectroscopic methods and comparison with literature data. All isolated compounds were evaluated for their anti-inflammatory effects in LPS-activated RAW264.7 cells. Compounds 1 and 2 exhibited inhibitory effects on iNOS at the concentration of 30 μmol·L.

ABSTRACT

Exogenous calcium can enhance the resistance of certain plants to abiotic stress. However,the role of calcium insaltstressed honeysuckle is unclear. The study is aimed to investigate the effects of exogenous calcium on the biomass,chlorophyll content,gas exchange parameters and chlorophyll fluorescence of honeysuckle under salt stress. The results showed that the calcium-treated honeysuckle had better photochemical properties than the salt-stressed honeysuckle,such as PIABS,PItotal,which represents the overall activity of photosystemⅡ(PSⅡ),and related parameters for characterizing electron transport efficiency φP0,ψE0,φE0,σR,and φR are significantly improved. At the same time,the gas exchange parameters Gs,Ci,Trare also maintained at a high level. In summary,exogenous calcium protects the activity of PSⅡ,promotes the transmission of photosynthetic electrons,and maintains a high Ci,therefore enhances the resistance of honeysuckle under salt stress.

ABSTRACT

Exogenous calcium can enhance the resistance of certain plants to abiotic stress. Research have demonstrated that exogenous calcium could enhances the resistance of honeysuckle under salt stress by promoting the transmission of photosynthetic electrons.The aim of this study was to investigate the effects of exogenous calcium on the contents of Na~+,K~+,Ca~(2+),Mg~(2+)and the expression of photosynthetic related genes Cab and rbc L. In this study,we used ICP-OES to analysis ion contents and used qRT-PCR to analysis the expression patterns of Cab and rbc L. The results showed that CaCl_2 significantly enhanced the K~+-Na~+,Ca~(2+)-Na~+,Mg~(2+)-Na+ratio of honeysuckle treated with 50 and 100 mmol·L~(-1) NaCl. Meanwhile,Cab and rbc L were significantly up-regulated under short-term salt stress,and CaCl_2 promoted this trend. From the two gene expression patterns,rbc L rapidly up-regulated on the first day of stress and then decreased,and was more sensitive to environmental changes. In summary,exogenous calcium could alleviate salt stress and increase plant development by increasing intracellular K~+-Na~+,Ca~(2+)-Na~+,Mg~(2+)-Na+ratio,and the transient overexpression of Cab and rbc L.

ABSTRACT

This study aims to explore the evaluation model for the proficiency testing of heavy metal and harmful element residues in pharmaceuticals,and to provide reference for the proficiency testing program and proficiency testing result in the field of residue analysis. The proficiency test result of cadmium determination in honeysuckle as an example. The algorithm A,NIQR,and Horwitz function are used to calculate the assigned value and the standard deviation. Z was obtained at the same time. If | Z | ≤2,the result is satisfactory. If 2< | Z | <3,the result is questionable. If | Z | ≥3,the result is unsatisfactory. In addition,the median value is the assigned value,and deviation(D%) is used. If D% is not more than 16%,the result is satisfactory; if D% is more than 16%,the result is unsatisfactory. After analysis,in the results of questionable or dissatisfied laboratories calculated by algorithm A and NIQR,the deviation error of some data is within the scope of the standard. In the results of the satisfactory laboratory evaluated by the Horwitz function,some data deviation errors far exceed the standard range. The evaluation result of the D% meets the requirements. According to heavy metal and harmful element trace analysis methods,this study is the first to apply D% to the evaluation of the detection ability of heavy metals and harmful elements in pharmaceuticals. This method makes the evaluation result more reasonable,and has important reference significance for the evaluation of other proficiency test results.

ABSTRACT

The study was aimed to determine the efficacy of two pesticides in the control of aphids in Lonicera japonica, and study the applicability of pesticides in L. japonica. The number of insects was counted before and 2, 3, 7 and 10 days after the application of pesticide in the test area within different dosage groups. The method was 5-point sampling method. Five aphids on the L. japonica branches were selected, then the number of insects was recorded. The effect of the two pesticides on the control rate of aphid was more than 80% at 1 d after application. The results showed that the two pesticides had good efficacy. After 7 days and 10 days, the control effect was 100%. After 1 day of spraying, the effect of the two pesticides on the control of L. japonica aphids was more than 80%, which was higher than that of the control agent. The results showed that the two pesticides had good and fast effect. After 7 days and 10 days of spraying, the control effect was 100%. The control effect of two kinds pesticides for aphid sprayed in recommended dose on the L. japonica is good and showed no hytotoxicity.
