Chemical components of Magnoliae Officinalis Cortex of different origins and with different tree ages before and after being processed with ginger juice:a qualitative and quantitative analysis / 中国中药杂志

This study aimed to investigate the impact of ginger juice on chemical profile of Magnoliae Officinalis Cortex(MOC) when they were processed together. Ultra-high-performance liquid chromatography coupled to quadrupole-orbitrap high-resolution mass spectrometry(UHPLC-Q-Orbitrap HRMS) was used for qualitative analysis of the chemical component of MOC samples before and after being processed with ginger juice. UPLC was performed to observe the content variation of eight main components in processed MOC. A total of 174 compounds were identified or tentatively deduced from processed and unprocessed MOC samples according to MS data obtained in positive and negative ion mode. After MOC was processed with ginger juice, the peak areas of most phenolics increased, while the peak areas of most phenylethanoid glycosides decreased; as for neolignans, oxyneolignans, other lignans and alkaloids, changes in the peak area were variable, and the peak areas of terpenoid-lignans varied little. Additionally, gingerols and diarylheptanoids were only detected in the processed MOC sample. The contents of syringin, magnoloside A, and magnoloside B decreased significantly in the processed MOC sample while no significant difference was observed in the contents of magnoflorine, magnocurarine, honokiol, obovatol, and magnolol. This study comprehensively explored the content variation of chemical components in processed and unprocessed MOC samples derived from different regions and with different tree ages using UPLC and UHPLC-Q-Orbitrap HRMS, and summarized the variation characteristics of various compounds. The results provide a data foundation for further research on pharmacodynamic substances of MOC processed with ginger juice.

Exploration of Zingiber officinale effects on growth performance, immunity and gut morphology in broilers / Exploração dos efeitos do Zingiber officinale no desempenho de crescimento, imunidade e morfologia intestinal em frangos de corte

Abstract The current study aimed to determine the effects of different levels of Zingiber officinale as a herbal feed additive on growth performance, carcass characteristic, serum biochemistry, total bacterial count (TBC), gut morphology, and immunological parameters of broilers. A total of 1500, day-old broiler chicks (Hubbard) were equally accredited to five treatment groups, each with six replicates (50 birds/replicate). Five experimental diets were prepared using basal diet i.e. with antibiotics positive control (PC), 3 g/kg ginger (group A), 6 g/kg ginger (group B), 9 g/kg ginger (group C) and without antibiotics negative control (NC). Group A and C showed significantly (p<0.05) higher feed intake (FI) as compared to other groups. Group C showed significantly (p<0.05) lower Total bacterial count (TBC) followed by group B as compared to NC. Carcass characteristics showed non-significant effects among different treatments. Mean villi length and width were significantly (p <0.05) higher in all ginger supplemented groups as compared to the control groups. Blood serum parameters including cholesterol, triglycerides, and low-density lipoproteins (LDL) were significantly (p<0.05) lower in groups B and C in comparison with the control groups. Whereas high-density lipoproteins (HDL) was significantly higher in group B as compared to the others. In conclusion, ginger supplementation @0.6% in the basal diet significantly improved growth performance and gut morphometry of broilers. It also showed a positive impact on cholesterol, triglycerides and gut microbes. Therefore, ginger could be a better substitute for antibiotic growth promoters.

Processing Magnoliae Officinalis Cortex with ginger juice: process optimization based on AHP-CRITIC weighting method and composition changes after processing / 中国中药杂志

The weight coefficients of appearance traits, extract yield of standard decoction, and total content of honokiol and magnolol were determined by analytic hierarchy process(AHP), criteria importance though intercrieria correlation(CRITIC), and AHP-CRITIC weighting method, and the comprehensive scores were calculated. The effects of ginger juice dosage, moistening time, proces-sing temperature, and processing time on the quality of Magnoliae Officinalis Cortex(MOC) were investigated, and Box-Behnken design was employed to optimize the process parameters. To reveal the processing mechanism, MOC, ginger juice-processed Magnoliae Officinalis Cortex(GMOC), and water-processed Magnoliae Officinalis Cortex(WMOC) were compared. The results showed that the weight coefficients of the appearance traits, extract yield of standard decoction, and total content of honokiol and magnolol determined by AHP-CRITIC weighting method were 0.134, 0.287, and 0.579, respectively. The optimal processing parameters of GMOC were ginger juice dosage of 8%, moistening time of 120 min, and processing at 100 ℃ for 7 min. The content of syringoside and magnolflorine in MOC decreased after processing, and the content of honokiol and magnolol followed the trend of GMOC>MOC>WMOC, which suggested that the change in clinical efficacy of MOC after processing was associated with the changes of chemical composition. The optimized processing technology is stable and feasible and provides references for the modern production and processing of MOC.

Chemical profile, anti 5-lipoxygenase and cyclooxegenase inhibitory effects of ginger (Zingiber officinale) rhizome, callus and callus treated with elicitors / Perfil químico, anti-5-lipoxigenase e efeitos inibitórios da ciclooxegenase do rizoma de gengibre (Zingiber officinale), do calo e calos tratados com elicitores

The present study investigated the chemical profiles and evaluated the inhibitory effect against 5-Lipoxygenase (5-Lox) activity for extracts of ginger rhizome, callus, and callus treated with the elicitors; yeast extract (100, 300 and 500 mg/L), glycine (100, 200 and 300 mg/L) and salicylic acid (100 and 200 mg/L). Oils and chloroform: methanol (CM) extracts were prepared by maceration in petroleum ether and CM (1:1, v/v), respectively. Chemical profiles were determined by gas chromatography/mass spectrometry (GC/MS) analysis. Oil of the callus recorded higher 5-Lox inhibitory effect (IC50 58.33±4.66 µg/mL) than the oil of rhizome (IC50168.34±15.64 µg/mL) and comparable to that of the positive control; Nordihydroguaiaretic acid (IC50 61.25±1.02 µg/mL). The chemical profile of the callus oil contained large amounts of fatty acids, mainly the unsaturated fatty acid oleic acid (31.11%) and saturated fatty acid palmitic acid (28.56%). Elicitors modified the chemical profile of the callus and ameliorated the anti-5-Lox activity of CM extract of the callus. CM extracts of callus treated with 100 and 300 mg/L yeast extract and 50 mg/L salicylic acid significantly suppressed (P ≤ 0.05) the 5-Lox activity by 33.16%, 25.46% and 16%, respectively as compared to the CM extract of untreated callus. In conclusion, ginger callus could be considered as a valuable dietary supplement in the treatment of various inflammatory disorders.

Em conclusão, o calo de gengibre pode ser considerado um suplemento dietético valioso no tratamento de vários distúrbios inflamatórios.

Finite element analysis method and optimization of flexible ginger moxibustion based on Abaqus and Taguchi method / 生物医学工程学杂志

Ginger moxibustion has the effect of regulating zang-fu organs and activating qi and blood circulation. When used, ginger paste is required to be close to human skin. Currently, the ginger box used clinically in the hospital can't meet the requirement of large area fitting human skin, and the efficacy of ginger moxibustion is significantly reduced. In this study, a flexible ginger paste box was proposed, which was composed of flexible components polydimethylsiloxane (PDMS), spring and wire netting. The large flexibility of the structure made it fit well with human skin. Finite element method was used to study the fitting degree between ginger paste box and waist soft tissue. Finite element models of flexible ginger paste box and waist soft tissue were established based on Hypermesh and Abaqus software. The equivalent contact area between the flexible ginger paste box and waist was obtained by numerical simulation under different PDMS unilateral thickness, spring wire diameter, wire netting diameter and ginger paste layer thickness. The four parameters were taken as the influencing factors, and the equivalent contact area was taken as the optimization objective. The typical value analysis and variance analysis of S/N were performed by Taguchi method, and the results showed that among the four influencing factors, the wire netting diameter had the largest influence on equivalent contact area and its contribution rate reached 41.98%. The contribution rates of PDMS unilateral thickness, spring wire diameter and ginger paste layer thickness reached 36.48%, 13.97% and 6.50%, respectively. The optimized PDMS unilateral thickness, spring wire diameter, wire netting diameter and ginger paste layer thickness were 1.5, 0.4, 0.15, 35 mm, respectively, and the equivalent contact area was 95.60 cm 2. The optimized flexible ginger paste box with great fitting performance can improve the effect of ginger moxibustion.

Based on the previous research results of our group and literature research, the chemical components, mechanisms, pharmacodynamics, and pharmacokinetics of Zingiberis Rhizoma Carbonisata were summarized to determine the quality markers(Q-markers) of Zingiberis Rhizoma Carbonisata and Zingiberis Rhizoma. Our research group has clarified the differential components of Zingiberis Rhizoma Carbonisata and Zingiberis Rhizoma, the meridian-warming hemostatic effect of Zingiberis Rhizoma Carbonisata, the related targets and pathways of the effect, the endogenous biomarkers of Zingiberis Rhizoma Carbonisata, and the hemodynamic processes of Zingiberis Rhizoma Carbonisata and Zingiberis Rhizoma. Moreover, based on high-performance liquid chromatography-diode array detector-electrospray ionization mass spectrometry(HPLC-DAD-ESIMS), a method for determining the content of Q-mar-kers was established. In conclusion, the study finally determined that gingerone, 6-shogaol, and diacetyl-6-gingerol were the Q-mar-kers of Zingiberis Rhizoma Carbonisata decoction pieces, and 6-gingerol, 8-gingerol, and 10-gingerol were Q-markers of Zingiberis Rhizoma decoction pieces. The result is expected to provide a reference for the establishment of quality standards for Zingiberis Rhizoma Carbonisata decoction pieces and Zingiberis Rhizoma decoction pieces.

Modulation of gut microbiota during alleviation of antibiotic-associated diarrhea with Zingiberis Rhizoma / 中国中药杂志

This study was aimed to explore the effect of Zingiberis Rhizoma extract on rats with antibiotic-associated diarrhea(AAD), and reveal the modulation of gut microbiota during alleviation of AAD. AAD rat model was successfully established by exposing rats to appropriate antibiotic mixed solution. Peficon(70 mg·kg~(-1)·d~(-1)) was used as positive control, then rats were treated with 200 mg·kg~(-1)·d~(-1) and 400 mg·kg~(-1)·d~(-1) of Zingiberis Rhizoma extract for low and high dosage groups of Zingiberis Rhizoma extract, respectively. The weight changes of the rats were observed, and the degree of diarrhea were evaluated by fecal score, 120 min fecal weight and fecal water content. Colon tissues for histopathological examination were stained with hematoxylin and eosin(HE), and 16 S rRNA sequencing analysis of gut microbiota was performed. The results showed that compared with the model group, the degree of diarrhea, indicated by fecal water content, fecal score, and 120 min fecal weight of positive control group, Zingiberis Rhizoma low-dose group and Zingiberis Rhizoma high-dose group were significantly ameliorated. And the treatment of Zingiberis Rhizoma could significantly improve the pathological condition of colon tissue in AAD rats, especially the high dose of Zingiberis Rhizoma. In addition, 16 S rRNA sequencing analysis of gut microbiota showed that the diversity and abundance of gut microbiota were significantly improved and the reco-very of gut microbiota was accelerated after given high-dose of Zingiberis Rhizoma, while no significant changes of alterations were observed after given Pefikon. Of note, compared with the pefikon group, the abundance and diversity of gut microbiota in Zingi-beris Rhizoma high-dose group were significantly elevated. At the phylum level, the abundance of Firmicutes in AAD rats increased and the abundance of Proteobacteria was decreased after the Zingiberis Rhizoma intervention. At the genus level, the abundance of Bacillus spp., Lachnoclostridium and Escherichia coli-Shigella were decreased, and the abundance of Lactobacillus spp., Trichophyton spp., and Trichophyton spp., etc., were increased. While compared with the AAD model group, there was no significant difference of gut microbiota after given Peficon. The results showed that Zingiberis Rhizoma exerted beneficial health effects against AAD, and positively affected the microbial environment in the gut of rats with AAD.

Aiming to solve the poor compactibility of the alcoholic extract of Zingiberis Rhizoma(ZR), this study explored the feasibility of its physical modification using co-spray drying with a small amount of hydroxypropyl methyl cellulose(HPMC). Based on the univariate analysis, the influence of two independent variables(the HPMC content in the product and the solid content of spray material) on the powder properties and tablet properties of the dried product was investigated by the central composite design. With the tensile strength and disintegration time of the tablets as the evaluation indexes, the optimal prescription was determined as follows: the HPMC content was 15% and the solid content of spray material was 25.6%. The accuracy of the regression model established for predicting tensile strength and disintegration time of tablets was verified, and the results revealed that the measured values were close to the predicted ones with deviations of 0.47% and-8.2%, indicating good prediction and reproducibility of the model. The tensile strength(4.24 MPa) of tablets prepared with the optimal prescription was 3.59 times that(1.18 MPa, far lower than the baseline of 2 MPa for qualified tablets) with the spray-dried powder of the ZR. On the other hand, due to the addition of HPMC, the disintegration time of tablets increased from 7.3 min to 24.6 min. On the whole, this study provided a new strategy to solve the common problem of poor compactibility of raw Chinese medicinal materials, which facilitated the successful preparation of Chinese medicinal tablets with high drug loads.

Performance of ginger crop under different irrigation depths / Desempenho da cultura do gengibre sob diferentes lâminas de irrigação

In order to achieve good yields and profitability from ginger crops, the water supply must be adequate. However, there are few studies available which have evaluated the adequate water supply to this vegetable. The objective of this study was to evaluate the effect of different irrigation depths on the development and productivity of ginger plants. The research was conducted at the "Sítio Schmidt" farm located in the municipality of Santa Maria de Jetibá, in the central mountainous region of Espírito Santo State, Brazil. The experimental design was a randomized block design with four replications, each experimental unit consisting of three rows at a spacing of 0.90 m and 0.10 m between plants of two meters extension, totaling 20 experimental units. The treatments consisted of application of five irrigation depths equivalent to: 50%, 75%, 100%, 125% and 150% of crop evapotranspiration (ETc). We evaluated the number of sprouts; average mass of export quality rhizome; the production of export, small and total rhizomes (t ha-1); and water use efficiency. The total water depth applied in the range 1100­1200 mm per cycle favors the development of ginger plants, providing the highest yields of total and export rhizomes, the greatest average mass of export quality rhizome and lowest production of small rhizomes.

Para que se alcance bons rendimentos e lucratividade com a cultura do gengibre o fornecimento de água deve ser adequado. Entretanto, ainda são poucos os trabalhos que avaliam o adequado fornecimento de água para esta hortaliça. Frente a isso, objetivou-se avaliar o efeito de diferentes lâminas de irrigação no desenvolvimento e na produtividade da cultura do gengibre. A pesquisa foi conduzida na propriedade "Sítio Schmidt" localizada no município de Santa Maria de Jetibá, região Central Serrana do Estado do Espírito Santo. O delineamento experimental utilizado foi o de blocos casualizados, com quatro repetições, sendo cada unidade experimental constituída por três fileiras em um espaçamento de 0,90 m e 0,10 m entre plantas de dois metros de extensão, totalizando 20 unidades experimentais. Os tratamentos consistiram na aplicação de cinco lâminas de irrigação, sendo elas: 50%, 75%, 100%, 125% e 150%. Foram avaliados o número de brotações; a massa média dos rizomas com padrão tipo exportação; as produtividades de rizomas tipo exportação, pequeno e total (t ha-1); e a eficiência do uso da água. A lâmina total aplicada na faixa de 1100-1200 mm por ciclo, ou seja, 75 a 100% da ETc favorece o desenvolvimento de plantas de gengibre, proporcionando maiores produtividades de rizoma total e tipo exportação, maior massa média de rizoma tipo exportação e menor produção de rizomas pequenos.

Purpose: evaluate the antimicrobial activity of intracanal dressings and their influence on dentinal colour changes. Material and methods: eighty single-rooted human extracted teeth were decoronated and divided into eight groups (n=10) according to intracanal dressing protocols inserted into the root canals: G1­distilled water (DW); G2­2% chlorhexidine gel (CHX); G3­calcium hydroxide (Ca[OH]2)+DW; G4­grape seed extract (GSE)+DW; G5­ginger extract (GE)+DW; G6­Ca(OH)2+CHX; G7­GSE+CHX; and G8­GE+CHX. The antimicrobial activity was evaluated by colony-forming units (CFUs) counting and dentinal colour changes was evaluated by digital spectrophotometry. Data were statistically analysed by One-way ANOVA followed by Tukey´s post hoc test (antimicrobial evaluation) and non-parametric Wilcoxon followed by the Mann- Whitney-U test (colour change evaluation) (α=0.05). Results: the highest bacterial reduction was observed in groups 4, 6, 7 and 8, with no significant difference between them (p<0.05). Groups 4 and 7 showed the highest medians of dentinal colour change (p<0.05). Conclusion: the addition of CHX improved the antimicrobial activity of GE-based intracanal dressing, with no effect in GSE-based intracanal dressing; moreover, these protocols induced significant dentinal colour changes.
