英文标题:
中文摘要: 目的:建立同时测定黄芪药材中黄酮类成分含量的方法,探讨黄芪药材中黄酮类成分与品种、产地和种植方式的关系。方法:采用高效液相色谱法。色谱柱为Venusil ASB,流动相为乙腈-0.3%甲酸(梯度洗脱),流速为1.0 ml /min,检测波长为260 nm,柱温为25 ℃。比较多省份28批野生和栽培的蒙古黄芪和膜荚黄芪的药材质量。结果:毛蕊异黄酮苷、芒柄花苷、毛蕊异黄酮和芒柄花素检测质量浓度线性范围分别为0.008 9~2.224 mg/ml(r=0.999 5)、0.005 2~1.3 mg/ml(r=0.999 6)、0.002 8~0.697 6 mg/ml(r=0.999 9)、0.002~0.5 mg/ml(r=0.999 9);精密度、稳定性、重复性试验的RSD<1%;加样回收率分别为99.52%~100.74%(RSD=0.41%,n=6)、98.84%~100.60%(RSD=0.60%,n=6)、98.47%~101.74%(RSD=1.08%,n=6)、100.10%~101.59%(RSD=0.32%,n=6)。从品种分析,蒙古黄芪药材中毛蕊异黄酮苷、芒柄花苷、总黄酮的含量要高于膜荚黄芪,但毛蕊异黄酮、芒柄花素的含量少于膜荚黄芪;从产地分析,内蒙古、山西产黄芪药材中毛蕊异黄酮苷、总黄酮的含量最高,东北、甘肃次之,山东、安徽、陕西较低;从种植方式分析,野生黄芪药材中毛蕊异黄酮苷、芒柄花苷、总黄酮的含量高于栽培品种,栽培黄芪药材中毛蕊异黄酮、芒柄花素含量高于野生品种。结论:该方法操作简便、稳定、重复性好,可用于黄芪药材中黄酮类成分含量的同时测定。不同产地黄芪药材中4种黄酮类成分含量差异大,药材的品种、产地和种植方式是影响黄芪质量的主要因素。
英文摘要:

OBJECTIVE:To establish a method for the simultaneous determination of flavonoids components in Astragali Radix, and to explore the relationship among flavonoids components, varieties,origins and planting patterns. METHODS: HPLC was performed on the column of Venusil ASB with mobile phase of acetonitrile-0.3% formic acid (gradient elution) at a flow rate of 1.0 ml/min, detection wavelength was 260 nm, and column temperature was 25 ℃. Medicinal material quality of Astragalus membranaceus (Fisch.) Bge. var. mongholicus (Bge.) Hsiao and A. membranaceus (Fisch.) Bge of wild and cultivated from different province was compared. RESULTS: The linear range of the mass concentration was 0.008 9-2.224 mg/ml for calycosin glucoside (r=0.999 5), 0.005 2-1.3 mg/ml for ononin(r=0.999 6), 0.002 8-0.697 6 mg/ml for calycosin (r=0.999 9) and 0.002-0.5 mg/ml for formononetin (r=0.999 9); RSDs of precision, stability and reproducibility tests were lower than 1%; recoveries were 99.52%-100.74%(RSD=0.41%,n=6) for  calycosin glucoside,98.84%-100.60%(RSD=0.60%,n=6) for ononin ,98.47%-101.74%

(RSD=1.08%,n=6) for calycosin,100.10%-101.59%(RSD=0.32%,n=6) for formononetin. In terms of varieties, the contents of calycosin glycosides, ononin and flavonoids in A. membranaceus (Fisch.) Bge. var. mongholicus (Bge.) Hsiao were higher than those of A. membranaceus (Fisch.)Bge, but the contents of calycosin and formononetin were less than those of A. membranaceus (Fisch.)Bge; in terms of origins, calycosin glycosides and flavonoids of Inner Mongolia and Shanxi held the highest contents, followed by those of Northeast China and Gansu, and lowest in Shandong, Anhui and Shaanxi; in terms of planting patterns, the contents of calycosin glycosides, ononin and flavonoids of wild Astragali Radix were higher than those of cultivated varieties, and the contents of calycosin and formononetin of cultivated varieties were higher than those of wild ones. CONCLUSIONS: The method is simple, stable and reproducible, and can be used for the simultaneous determination of flavonoids components in Astragali Radix.The flavonoids components show great differences in Astragali Radix from different origins, and they are affected by varieties, origins and planting patterns.
