Aim A reliable and rapid HPLC method was developed for quantitative determination of coniferyl femlate, an ester of ferulic acid, with multiple pharmacological activities in Angelica sinensis and Ligusticum chuanxiong, two commonly used Chinese medicines. Methods The determination was achieved by using a Zorbax ODS C18 analytical column (250 mm×4.6 mm ID, 5 μm) at isocratic elution of 1% aqueous acetic acid and acetonitrile (1:1) with diode-array detection (318 nm). The calibration curve of coniferyl femlate showed good linearity (r^2 = 0.9995) within the test range. Results The developed method showed good precision with intra- and inter-day variations of 0.22% - 1.16% and 0.86% - 2.62% between the levels of 0.380 - 0.038 mg·mL^-1, respectively. The repeatability represented as RSD of coniferyl femlate was less than 2.7% for three levels (0.2 - 1.0 g of Angelica sinensis), and the recovery was 105.3% with RSD of 3.2%. Conclusion The validated method was successfully applied to quantify coniferyl femlate in 12 samples of Danggui and Chuanxiong. 展开更多

Background:Non-alcoholic fatty liver disease(NAFLD)is a liver disease of unknown etiology.A traditional Chinese medicine Ligusticum chuanxiong Hort.(CX),it has been used about 2,000 years.Until now,the mechanism of action of CX on NAFLD remains unclear.Method:We first tested the toxicity of CX to AML12 cells with CCK-8.In vitro cell models of NAFLD were made using free fatty acid,and used Oil Red O staining tested lipid droplets.Then the active compounds of CX were collected from TCMSP and literatures,and SwissTargetPrediction,Search Tool for Interacting Chemicals,Encyclopedia of Traditional Chinese Medicin,Bioinformatics Analysis Tool for Molecular mechANism of Traditional Chinese Medicine database were used to predict the targets of the compounds.DRUGBANK,Online Mendelian Inheritance in Man,Therapeutic Target Database,DisGeNET and GeneCards database were used to predict the targets of NAFLD.Use Venn diagram to obtained the intersection targets by,and analyzed the protein-protein intersection network.Use Kyoto Encyclopedia of Genes and Genomes and Gene Ontology to forecast the function of intersection genes.Molecular docking was used to evaluate the interaction between hub gene and active ingredients.Finally,use western blotting to determine the effects of CX on PPARA,PPARG,IL1B and TNF proteins.Result:CX can reduce the production of AML12 cell lipid droplets.A total of 15 chemical components were identified from CX.Folic acid,chrysophanol and sitosterol were the main components of CX against NAFLD.ALB,TNF,PPARG and PPARA proteins were the main targets of CX in the treatment of NAFLD.PPAR signaling pathway and fatty acid degradation were closely related to anti-NAFLD.Molecular docking results shows that folic acid was the main active ingredient of CX for NAFLD treatment,and TNF is the main potential target.The cellular NAFLD model showed that CX up-regulated the expression of PPARA and PPARG protein and down-regulated inflammatory factor IL-1B and TNF expression.Conclusion:Our study suggests that CX has a therapeutic effect on NAFLDA,which may be related to the PPAR pathway and the reduction of inflammatory cytokines. 展开更多

[Objective] The research aimed to isolate and identify the pathogen of anthracnose of Ligusticum chuanxiong Hort,and make the antifungal test on four kinds of fungicides for selecting the optimum fungicides.[Method] The pathogenic fungi was separated according to Koch's rule and the shape characteristics were identified. The antifungal test of fungicides was made by using plate mycelium growth inhibition method.[Result] The pathogenic fungi was separated from leaves of Ligusticum chuanxiong Hort. and morphological characters were consistent with that of Colletotrichum gloeosporioides. In addition to chloroisobromine cyanuric acid,the other three fungicides could inhibit the mycelium growth. The growth inhibition rates of 1 000 times Metalaxyl+mancozeb,zineb,Thiophanate-methyl for the mycelium were 26.8%,22.1%,59.8% respectively after 7 days.[Conclusion] The anthracnose was caused by Colletotrichum gloeosporioides. Ligusticum chuanxiong Hort. was a new record host plant of Colletotrichum gloeosporioides and the best inhibiting fungicide was Thiophanate methyl. 展开更多

Extraction of the Ligusticum Chuanxiong oil with supercritical CO2 (SC-CO2) was investigated at the temperatures ranging from 55℃ to 70℃ and pressure from 25 MPa to 35 MPa. The mass of Ligusticum Chuanxiong oil extracted increased with pressure at constant temperature. The initial slope of the extraction was considered as the solubility of oil in SC-CO2. Chrastil equation was used to correlate the solubility data of Ligusticum Chuanxiong oil. An improved Chrastil equation was also presented and was employed to correlate the solubility data, The correlation results show that the values of the average absolute relative deviation are 5.94% and 3.33% respectively, indicating the improved version has better correlation accuracy than that of Chrastil equation. 展开更多

Objective: To explore the mechanism of Chuanxiong in alleviating hypoxic pulmonary hypertension in rats by inhibiting pulmonary vascular remodeling. Methods: Thirty healthy and clean male SD rats weighing (180 - 220) g were randomly divided into three groups (n = 10): normoxia group (n), hypoxia group (H) and Chuanxiong group (L). Group N was fed in normoxic environment, and the other two groups were fed in hypoxic (9% 11% O2) environment for 4 weeks, 8 h/D, 6 days a week. Rats in group L were gavaged with Ligusticum chuanxiong solution diluted with normal saline at the concentration of 300 mg/kg, and rats in group H were gavaged with equal volume of normal saline. After 4 weeks, the mean pulmonary artery pressure was measured. After pulmonary perfusion, the right ventricular free wall and left ventricle plus ventricular septum were taken to measure the right ventricular hypertrophy index. The changes of pulmonary morphology and ultrastructure were observed under light microscope. Results: Compared with group n, the average pulmonary artery pressure and right ventricular hypertrophy index in the other two groups increased, and the thickening of pulmonary vascular wall was obvious under microscope (P Conclusion: Ligusticum chuanxiong can relieve pulmonary artery pressure in rats by inhibiting pulmonary vascular remodeling. 展开更多

目的探究川芎挥发油对雷公藤甲素体外透皮性能和细胞毒性的影响。方法采用气相色谱-质谱联用法对川芎挥发油的化学成分进行分析。分离KM小鼠下腹皮肤,分为雷公藤甲素、雷公藤甲素配伍川芎挥发油1∶10、1∶50、1∶100组(以下简称“配伍1... 目的探究川芎挥发油对雷公藤甲素体外透皮性能和细胞毒性的影响。方法采用气相色谱-质谱联用法对川芎挥发油的化学成分进行分析。分离KM小鼠下腹皮肤,分为雷公藤甲素、雷公藤甲素配伍川芎挥发油1∶10、1∶50、1∶100组(以下简称“配伍1∶10“”配伍1∶50”“配伍1∶100”组),将各组小鼠皮肤与相应乳膏各0.2 g充分接触24 h后,采用高效液相色谱法测定各组接收液中雷公藤甲素的累计透皮量(Q_(n)),并计算透皮吸收速率(J_(ss));再以人永生化角质形成细胞(HaCat)为模型,采用CCK-8法检测不同浓度川芎挥发油和雷公藤甲素配伍前后的细胞存活率。结果共鉴定出62个川芎挥发油化学成分,包括Z-藁本内酯、洋川芎内酯、β-瑟林烯等。与雷公藤甲素组比较,配伍1∶10组和配伍1∶50组24 h内雷公藤甲素的Q_(n)(P<0.01)和J_(ss)有所升高,而配伍1∶100组的Q_(n)(P<0.05)和J_(ss)有所下降。与雷公藤甲素组比较,雷公藤甲素浓度在36、72、144 ng/mL时,配伍1∶10组和配伍1∶50组可以显著提高HaCat细胞的存活率(P<0.05或P<0.01),而配伍1∶100组细胞的存活率反而降低,但差异无统计学意义(P>0.05)。结论雷公藤甲素与川芎挥发油在配伍比例为1∶10和1∶50时可以促进雷公藤甲素的透皮吸收,且可降低雷公藤甲素对HaCat细胞的毒性。 展开更多
