ABSTRACT

This paper aims to investigate the protective effect and mechanism of Astragalus membranaceus and Angelica sinensis before and after compatibility against triptolide(TP)-induced hepatotoxicity. The experiment was divided into a blank group, model group, Astragalus membranaceus group, Angelica sinensis group, and compatibility groups with Astragalus membranaceus/Angelica sinensis ratio of 1∶1, 2∶1, and 5∶1. TP-induced hepatotoxicity model was established, and corresponding drug intervention was carried out. The levels of alanine transaminase(ALT), aspartate transaminase(AST), and alkaline phosphatase(ALP) in serum were detected. Pathological injuries of livers were detected by hematoxylin-eosin(HE) staining. The levels of malondialdehyde(MDA), superoxide dismutase(SOD), glutathione peroxidase(GSH-Px), and reduced glutathione(GSH) in the liver were measured. Wes-tern blot method was used to detect the expression of nuclear factor erythroid 2-related factor 2(Nrf2), Kelch-like ECH-associated protein 1(Keap1), peroxisome proliferator-activated receptor gamma, coactivator-1 alpha(PGC-1α), heme oxygenase-1(HO-1), and NAD(P)H quinone dehydrogenase 1(NQO1) in livers. Immunofluorescence was used to detect the expression of Nrf2 and PGC-1α in livers. The results indicated that Astragalus membranaceus/Angelica sinensis ratio of 2∶1 and 5∶1 could significantly reduce the levels of serum AST, ALT, and ALP, improve the pathological damage of liver tissue, increase the levels of GSH and GSH-Px, and reduce the content of MDA in liver tissue. Astragalus membranaceus/Angelica sinensis ratio of 1∶1 and 2∶1 could significantly improve the level of SOD. Astragalus membranaceus and Angelica sinensis before and after compatibility significantly increased the protein expression of HO-1 and NQO1, improved the protein expression of Nrf2 and PGC-1α, and decreased the protein expression of Keap1 in liver tissue. The above results confirmed that the compatibility of Astragalus membranaceus and Angelica sinensis had antioxidant effects by re-gulating Keap1/Nrf2/PGC-1α, and the Astragalus membranaceus/Angelica sinensis ratio of 2∶1 and 5∶1 had stronger antioxidant effect and significantly reduced TP-induced hepatoto-xicity.

ABSTRACT

The demand for Angelicae Sinensis Radix, the dry root of Angelica sinensis, has been increasing year by year. However, the continuous cropping obstacles, frequent occurrence of pests and diseases, overuse of chemical pesticides, excessive pesticide residues and other problems in Angelicae Sinensis Radix production have attracted much attention. In this paper, we summarized the common diseases and pests attacking Angelica sinensis as well as the detection methods and characteristics of pesticide residues in Angelicae Sinensis Radix from 2002 to 2021. Additionally, we compared the limit standards of pesticide residues in Angelicae Sinensis Radix in and out of China and put forward suggestions for the high-quality and green development of Angelicae Sinensis Radix industry conside-ring the existing problems. The pesticide residues in Angelicae Sinensis Radix have been changing from organochlorines to organophosphorus pesticides. In recent years, some organophosphorus pesticides such as phorate, phoxim, isofenphos-methyl, phorate-sulfoxide, fenamiphos, isocarbophos, omethoate, and triazophos in Angelicae Sinensis Radix have seriously exceeded the standards. The detection methods of pesticide residues has evolved from chromatography to high performance chromatography-mass spectrometry, gas chromatography-mass spectrometry(GC-MS), and liquid chromatography-mass spectrometry(LC-MS), and some new detection techniques such as immunoassay have also been applied. Pesticide residues have become a primary factor that restricting the development of Angelicae Sinensis Radix industry. Therefore, moderate application of pesticides, establishment of ecological planting system, and strict limit standards of pesticide residues are necessary to solve the pesticide residue problem.

ABSTRACT

The pharmacological effects of Angelicae Sinensis Radix from different producing areas are uneven. Accurate identification of its producing areas by computer vision and machine learning(CVML) is conducive to evaluating the quality of Angelicae Sinensis Radix. This paper collected the high-definition images of Angelicae Sinensis Radix from different producing areas using a digital camera to construct an image database, followed by the extraction of texture features based on the grayscale relationship of adjacent pixels in the image. Then a support vector machine(SVM)-based prediction model for predicting the producing areas of Angelicae Sinensis Radix was built. The experimental results showed that the prediction accuracy reached up to 98.49% under the conditions of the model training set occupying 80%, the test set occupying 20%, and the sampling radius(r) of adjacent pixels being 2. When the training set was set to 10%, the prediction accuracy was still over 93%. Among the three producing areas of Angelicae Sinensis Radix, Huzhu county, Qinghai province exhibited the highest error rate, while Heqing county, Yunnan province the lowest error rate. Angelicae Sinensis Radix from Minxian county, Gansu province and Huzhu county, Qinghai province were both wrongly attributed to Heqing county, Yunnan province, while most of those from Huzhu county, Qinghai province were misjudged as the samples produced in Minxian county, Gansu province. The method designed in this paper enabled the rapid and non-destructive prediction of the producing areas of Angelicae Sinensis Radix, boasting high accuracy and strong stability. There were definite morphological differences between Angelicae Sinensis Radix samples from Minxian county, Gansu province and those from Huzhu county, Qinghai province. The wrongly predicted samples from Minxian county, Gansu province and Huzhu city, Qinghai province shared similar morphological characteristics with those from Heqing county, Yunnan province. Most wrongly predicted samples from Heqing county, Yunnan province were similar to the ones from Minxian county, Gansu province in morphological characteristics.

ABSTRACT

A HPLC method was established for simultaneous determination of two organic acids(chlorogenic acid and ferulic acid) and five phthalides(senkyunolide I, senkyunolide H, senkyunolide A, ligustilide, and butylidenephthalide) in Angelicae Sinensis Radix and its processed products to clarify the underlying material transferring rules. The analysis was performed on a Welch Ultimate C_8 column(4.6 mm×250 mm, 5 μm) with acetonitrile(A)-0.085% phosphoric acid water(B) as the mobile phase in a gradient elution mode at the flow rate of 1.1 mL·min~(-1), the column temperature of 25 ℃, the detection wavelength of 280 nm, and the injection volume of 10 μL. Under these conditions, the content of the above-mentioned seven components was analyzed in 15 batches of Angelicae Sinensis Radix and its processed products, and the transfer rate of each compound was calculated. As a result, in the processed products, the average content of chlorogenic acid was slightly decreased and that of ferulic acid was equivalent to the medicinal materials. The content of senkyunolide I, senkyunolide H, senkyunolide A, and butylidenephthalide showed an increasing trend in the processed products as compared with the medicinal materials. The mass fraction of ligustilide in the medicinal materials was above 0.7%(0.94% on average), meeting the requirement of 0.6% in the Hong Kong Chinese Materia Medica Standards, but was 0.47% on average in the processed products, which was decreased by 50% approximately. Further investigation showed that the content of ligustilide in freshly made processed products of Angelicae Sinensis Radix did not change significantly compared with that in the medicinal materials, indicating that the loss of ligustilide in the processed products mainly occurred in the storage. Therefore, Angelicae Sinensis Radix is suitable for storing in the form of medicinal materials and the freshly made processed products should be used except for special cases. Additionally, it is recommended to control the content of volatile oils or ligustilide in medicinal materials and processed products of Angelicae Sinensis Radix to ensure its effectiveness in clinical medication.

ABSTRACT

In order to discuss the "entropy weight method" for weighting various indicators in the comprehensive evaluation of Angelicae Sinensis Radix slices(ASR), the quality of ASR was comprehensively evaluated by entropy weight-based gray systematic theory and cluster analysis. In this study, the contents of ferulic acid, volatile oil, polysaccharide, alcohol extract, water extract, moisture, total ash and acid-insoluble ash in 44 batches of ASR from different sources were determined. The entropy weight method was used for objective weighting. With relative correlation(r_i) as a measure, a multi-index comprehensive evaluation model was constructed for the quality of ASR. The results showed that the relative correlation value of 44 batches of ASR ranged from 0.301 9 to 0.662 9. There were certain differences in the quality of ASR from different sources. The ASR S1-S8, traceable and standardized in processing techno-logy, showed a high relative correlation degree and high quality ranking, indicating that the implementation of systemic management of the production chain of Chinese herbal pieces was beneficial to the quality control of ASR. The quality evaluation results of 44 batches of ASR were consistent with those of traditional geo-authentic habitats for ASR and the mainstream varieties of ASR on market, and basically consistent with the results of cluster analysis. This study suggests that the gray systematic theory based on the entropy weighting method can be used for the quality evaluation of ASR. The objective weighting of the entropy weight method improves the reliability of the gray correlation method and the scientificity of ASR quality evaluation.

ABSTRACT

Wild Angelica sinensis is almost endangered, studying the biological characteristics of wild A. sinensis seeds is helpful for varietal improvement and its conservation. This paper systematically studied the morphological structure, thousand seed weight, viability, storage and other basic biological characteristics of wild A. sinensis fruits and seeds, and focused on the germination of excised embryos,the development of embryo, the effects of the temperature,light and hormones on seed germination.The study found that:①The embryos are not fully developed when harvested, the initial germination rate was low, the embryos can develop. After 15 days of low temperature storage, the embryos can develop completely and the germination rate is significantly increased. These results show that wild A. sinensis seeds have no dormancy, and the low germination rate is due to the low maturity of wild A. sinensis seeds. ②The sui-table germination temperature of wild A. sinensis is 15-25 ℃,and the optimal temperature is 20 ℃. Light does not affect the germination of A. sinensis seeds.③The applicable concentration of GA_3 can promote seeds germination, IAA and 6-BA has no significant effect on germination.④The optimum storage condition is dry storage at 4 ℃. Wild A. sinensis seeds can be stored for 1.5 years and cultivated seeds can be stored for 1 year.During the introduction and conservation, the best treatment conditions were dry storage at 4 ℃ for 30 d and soaking seeds with 200 mg·L~(-1) GA_3, the germination rate can reach 86.7%.

ABSTRACT

OBJECTIVE@#This study aims to evaluate the effect of Angelica sinensis polysaccharide (ASP) on the osteogenic differentiation of the bone marrow mesenchymal stem cells (BMSCs) of rats with high glucose levels.@*METHODS@#Rat BMSCs were isolated and identified by osteogenic and adipogenic differentiation. Then, the BMSCs were divided into three groups as follows: normal control group (5.5 mmol·L⁻¹ glucose), high glucose group (25.5 mmol·L⁻¹ glucose), and ASP+high glucose group (25.5 mmol·L⁻¹ glucose +40 mg·L⁻¹ ASP). The proliferation activities of the BMSCs were detected by CCK8. Alizarin red staining, and alkaline phosphatase activity were used in the examination of osteogenic activity. Quantitative real time-polymerase chain reaction was used to detect the expression levels of the osteogenic genes (Runx2, Osx, OCN, Col-Ⅰ) and the key factors of Wnt/β-catenin signal pathway (CyclinD1, β-catenin). In vivo, a type 2 diabetes rat model was established. The rats were divided into three groups, namely, the normal control group (normal rats), diabetes group (diabetic rats), diabetes+ASP group (diabetic rats, ASP feeding). Then, the tibia bone defect was established. The repair of bone defects in each group was observed through histological examination.@*RESULTS@#The proliferation of BMSCs was higher in the high glucose group and ASP+high glucose group than in the normal control group (P0.05). The number of calcium nodules of BMSCs; alkaline phosphatase activity; and the mRNA expression of Runx2, OCN, Osx, Col-Ⅰ, CyclinD1, β-catenin in the high glucose group were lower than those in the normal control and ASP+high glucose groups (P0.05). The bone mass was significantly lower in the bone defect of the diabetes group than in the bone defect of the normal control or diabetes+ASP group (P0.05).@*CONCLUSIONS@#ASP can promote the osteogenic differentiation of rat BMSCs under high glucose culture and induce bone regeneration in rats with type 2 diabetes. These features may be related to the activation of the Wnt/β-catenin signaling pathway.

ABSTRACT

A crude drug “Dang-Gui”, belonging to the genus Angelica, has been used as a traditional herbal medicine in Asia. Various studies have investigated the chemical components and pharmacological activities of Dang-Gui worldwide. However, domestic research results published in Korean are undervalued in international academia due to language barriers. Therefore, it is necessary to summarize the domestic research findings systematically for greater accessibility. This review focuses on the results published in four Korean pharmaceutical journals between 1970 and 2018, which detail the botanical, phytochemical, and pharmacological properties of three Angelica species (A. gigas, A. sinensis, and A. acutiloba) used as “Dang-Gui” in Korea, China, and Japan.

ABSTRACT

The drying process of different grades of Angelicae Sinensis Radix under low temperature and resurgence conditions was simulated based on the Weibull distribution function,in order to clarify the low-temperature moisture regain drying characteristics of different grades of Angelicae Sinensis Radix,and explore the effect of grade and drying conditions on the drying process of Angelicae Sinensis Radix. Research results indicated that the Weibull function can be used to simulate different grades of Angelicae Sinensis Radix low-temperature moisture regain drying process,and the lower the drying temperature,the smaller the grade,and the better the simulation effect. The grade and drying temperature showed a significant effect on the low-temperature moisture regain drying process of Angelicae Sinensis Radix,and the effect of temperature on the relative moisture regain rate of Angelicae Sinensis Radix was greater than the grade. The relative moisture regain rate of different grades of Angelicae Sinensis Radix at 40 ℃ was higher than 55 ℃,and the relative moisture regain rate at 40 ℃ was first class > second class > third class. After drying,the moisture ratio at 40 ℃ was lower than that at 55 ℃; the effect of the grade on the effective diffusion coefficient of dry water was greater than the temperature. Under different conditions of 40 ℃ and 55 ℃ moisture regain,the effective diffusion coefficient of water was between 2. 941 6×10-6-7. 991 5×10-6 and3. 093 8×10-6-8. 483 8×10-6 for different grades. Under the same temperature conditions,the effective diffusion coefficient of water was first class > second class > third class. Therefore,Weibull function can be used to study and simulate the drying characteristics of different grades of Angelicae Sinensis Radix under low-temperature moisture regain conditions,providing experimental basis for the improvement of traditional drying technology of Angelicae Sinensis Radix and the optimization of drying process of different specifications or grades of Angelicae Sinensis Radix.

ABSTRACT

Ten batches of Angelica sinensis from three producing areas( Tuoxiang,Minxian and Weiyuan of Gansu province) were selected as the research objects,and processed into raw A. sinensis,A. sinensis with alcohol,and A. sinensis with soil respectively through the standard processing methods. Ultra-high performance liquid chromatography( UPLC) was used to establish fingerprint for three processed products of A. sinensis,and determine the contents of 9 phenolic acids and phthalide compounds. The similarity was analyzed with Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine,which showed that the chromatographic peaks of the same processed samples of A. sinensis were basically similar,with all similarities greater than 0. 950. The difference between different processed products and their control spectra was not obvious,with all similarities also higher than 0. 950.On the basis of using principal component analysis( PCA) and OPLS-DA to seek the difference components between groups,the improved distance coefficient method can be used to effectively distinguish the three processed products of A. sinensis by fingerprint similarity. At the same time,the determination method of nine phenolic acids and phthalide in A. sinensis was established by UPLC,and the comparison between different processed products was carried out. The results showed that the content of various components was changed as compared with the raw A. sinensis. The contents of coniferyl ferulate and ligustilide in the A. sinensis with alcohol were increased significantly,and the content of coniferyl ferulate was obviously increased in A. sinensis with soil. The method established in this paper can effectively distinguish different processed products of A. sinensis and determine the content of the main components in them.

ABSTRACT

The study aims to investigate spatial distribution pattern and age structure of wild Angelica sinensis in Gansu province.Ten plots each with an area of 100 m2 were set and the spatial coordinates of all wild A. sinensis individuals were measured within each plot. Based on plant individual mapping data,we explored the spatial distribution pattern and its differences between different life history stages of wild A. sinensis in Gansu province by using nearest neighbor distance statistics. Correlation analysis were carried out to explore the relationship between spatial aggregation degree and topographic factors. We also distinguished individuals to three life history stages( i.e. seedlings,adults and boltings) and then test the differences among/between them using nonparametric test.(1)We found that the dominant spatial distribution pattern of wild A. sinensis population in Gansu was aggregated distribution. There was no significant correlation between spatial aggregation degree of wild A. sinensis and altitude,slope and aspect. There was no significant difference between the average distance from seedlings to their nearest bolting individuals; the average distance from adult individuals to their nearest seedlings was significantly larger than the average distance from adult individuals to their nearest adult individuals; and the average distance from bolting individuals to their nearest adult individuals was significantly smaller than the average distance from bolting individuals to their nearest bolting individuals.(2)The age structure was showed as a declining population,characterized by less seedlings and bolting individuals,while more adult individuals within population. The population characteristics of wild A. sinensis,characterized by aggregated distribution pattern and senescent type of age structure,are disadvantage to its population development. The factors,such as habitat specialization,human activities and intraspecific competition,which shapes the current population characteristics,may increase the threatened status of wild A. sinensis. We suggest to strengthen the protection of wild A. sinensis.

ABSTRACT

Ultra performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry(LC-MS) was used to establish the chromatography fingerprint for fresh(FRAS) and dry(RAS) roots of Angelica sinensis from 10 different places. The rat model of blood deficiency was established by acetyl-phenyl-hydrazine(APH) and cyclophosphamide(CTX). Then grey relational analysis(GRA) and partial least squares regression(PLS) were used to investigate the spectrum-effect relationship between the relative contents and the data of enriching blood pharmacodynamics efficacy. The results showed that the FRAS and RAS had certain enriching blood activities(P<0.05). The contribution degree of the FRAS and RAS to enriching blood activities of each common peaks were determined by regression coefficient. Among them, 4 common peaks contributed significantly to the effect of enriching blood activities, P1(unknown), P2(unknown), P7(ferulic acid), and P11(senkyunolide A) respectively. This paper investigated the spectrum-effect relationship between enriching blood activities and LC-MS chromatography fingerprint of RAS and FRAS, and determined the effective compositions of RAS and FRAS with enriching blood activities. It lays a theoretical foundation for the comprehensive development and utilization of A. sinensis.

ABSTRACT

Two proteins of similar molecular weight (named as ASPR-C-1 and ASPR-C-2) from the crude drug of Angelica sinensis were purified and characterized by 80% ammonium sulfate precipitation, Sephadex G-50 gel filtration chromatography, and DEAE-Sepharose anion exchange chromatography. The molecular weight of ASPR-C-1 and ASPR-C-2 on SDS-PAGE was 17.33 kDa and 17.18 kDa, respectively. They were mainly monomeric in solution, but partially formed dimers and they were glycoproteins with glycosyl content of 2.6% and 8.2%, respectively. Both ASPR-C-1 and ASPR-C-2 were identified to be members of pathogenesis-related 10 family of proteins by matrix-assisted laser desorption ionization time-of-flight mass spectrometry and have ribonuclease activities with the specific activity of 73.60 U/mg and 146.76 U/mg, respectively. The optimum pH of the two isoforms was similar, at about 5.6, while their optimum temperatures were different. The optimum temperature of ASPR-C-1 was 50 ℃, and that of ASPR-C-2 was 60 ℃. Both isoforms presented highest thermal stability at 60 ℃. However, ASPR-C-2 was more thermotolerant than ASPR-C-1. The latter was rapidly inactivated and retained only about 20% residual activity while the former still maintained about 80% of its original activity at a higher treatment temperature (80 to 100 ℃). In addition, Fe²⁺ had an activating effect on the ribonuclease activities of two isoforms while Ca²⁺, Mg²⁺, Zn²⁺, Mn²⁺, Ag⁺, Cu²⁺, EDTA (Elhylene diamine tetraacetic acid), dithiothreitol and sodium dodecylsulphate showed different degrees of inhibition of the enzyme activities. Our findings provide a foundation for further research on the biological function of PR-10 protein from Angelica sinensis.

ABSTRACT

As an important signal molecule, extracellular ATP(eATP) can regulate many physiological and biochemical responses to plant stress. In this study, the regulation of extracellular ATP(eATP) on chlorophyll content and chlorophyll fluorescence parameters of Angelica sinensis seedlings were studied under drought and low temperature stress. The results showed that all the chlorophyll content, the actual photochemical efficiency [Y(Ⅱ)], the electron transfer rate(ETR), the photochemical quenching coefficient(qP and qL) of A. sinensis leaves were significantly decreased under drought and low temperature stress, respectively. At the same time, non-photochemical quenching(NPQ and qN) were also all significantly increased, respectively. The application of eATP alleviated the decrease of chlorophyll content, Y(Ⅱ), ETR, qP and qL of A. sinensis leaves under drought and low temperature stress, and eliminated the increase of qN and NPQ. The results indicated that eATP could effectively increase the open ratio of PSⅡ reaction centers, and improve the electron transfer rate and light energy conversion efficiency of PSⅡ of A. sinensis leaves under drought and low temperature stress. It is beneficial to enhance the chlorophyll synthesis and the adaptability of PSⅡ about A. sinensis seedlings to drought and low temperature stress.

OBJECTIVE@#To study the effects of Angelicaesinensis radix (Danggui) decoction on the therapeutic action and the colonic morphology and mucus secretion in XuexuBianmi model mice.@*METHODS@#Sixty Kunming mice, maleandfemaleinhalf, were randomly divided into six groups according to gender and weight (=10):normal control group, XuexuBianmi model group, positive control group, and high-dose, middle-dose and low-dose Danggui groups. Except the normal control group, the mice in the rest groups were orally administrated with diphenoxylate (DPN) and subcutaneously injected with acetylphenyhydrazine (APH) and intraperitoneally injected with cyclophosphamide (CPA) to copy XuexuBianmi model. Fromthe 14th day, the mice in Danggui groups were orally administered with different doses of Danggui decoction (16.67、8.33、4.17 g/kg), the mice in positive control group were orally administered with Changtongshu granule (5 g/kg), the mice in XuexuBianmi model group were administered with normal saline (NS) at the same volume (10 ml/kg), once a day for consecutive 28 days. The general status were observed, the first black defecation time (FBDT), the water content in stool and in colon in mice of all groups were tested. And the colon tissue was stained with hematoxylin-eosin (HE) and AB-PAS to observe the changes of colonic morphology and the mucus secretion.@*RESULTS@#Compared with the normal control group, there appeared the XuexuBianmi syndromes in model group as follows, the defecation time (FBDT) was significantly prolonged, the water contentinstool and in colon were decreased (<0.01), the colonic mucosa and gland were atrophied, mucous membrane layer was thinned (<0.01), mucus secretion was decreased. Compared with the XuexuBianmimodel group, the Xuexu and Bianmi syndromes were improved, the FBDT was significantly shortened (<0.05, <0.01), the water content of colon was increased in the three groups of Danggui decoction (<0.05, <0.01). The water content of the stool was obviouslyincreased in groups of 16.67and 8.33kg.dDanggui decoction (<0.05). The atrophy of colon mucosa and gland was improved, the mucus secretion was increased, and the colon lubrication function was improved in the three groups in different doses of Danggui decoction.@*CONCLUSIONS@#Dangguican improve the mucosal atrophy, and increase the secretion of colonic mucus, then the stool is softened and promoted to discharge.

ABSTRACT

OBJECTIVE@#To study the intervention effects of Radix Hedysari, Radix Astragalus and compatibility of Angelica Sinensis on blood deficiency model mice induced by cyclophosphamide (CTX).@*METHODS@#The mice were randomly divided into 7 groups, 10 mice each group. The blood deficiency model was established by CTX. The blank group and model group were treated with saline by gavage, while mice in positive group were administered with Lvjiaobuxue granule. Four dosage group were administered with Radix Hedysari, Radix Hedysari-Radix Angelica Sinensis(5:1), Radix Astragalus and Radix Astragalus-Radix Angelica Sinensis(5:1) water decoction. All the drugs were administered to mice for consecutive 7 d. The contents of red blood cell (RBC), lymphocyte(LYM), hematocrit (HCT), white blood cell (WBC), platelet (PLT) were detected by hematology analyzer, while thymus index(TI), spleen index(SI), reticulocyte (RC), marrow karyocyte (MK) were calculated, and the femur by pathological section were observed by microscope.@*RESULTS@#Compared with blank group, the contents of RBC, WBC, HCT, PLT, LYM were decreased in model group (<0.05). Compared with model group, the contents of RBC, WBC, HCT, PLT, LYM, RC and marrow karyocyte were increased in Hedysari-Angelica Sinensis(5:1) and Astragalus Angelica Sinensis(5:1) (<0.05), at the same time, the pathological damage of femur could be improved.@*CONCLUSIONS@#The effect of enrichment blood on blood deficiency model mice in Hedysari-Angelica Sinensis (5:1) and Astragalus-Angelica Sinensis(5:1) were superior to Hedysari and Astragalus.
