不同产地及生长年限黄芪药材活性成分积累分布规律研究OA
Research on the accumulation and distribution pattern of active ingredients in Astragalus membranaceus from different origins and growth years
探究不同产地、不同生长年限黄芪药材中活性成分的积累分布规律,为有效控制黄芪药材质量提供依据.采用HPLC-ELSD法测定黄芪甲苷含量;HPLC-UVD法测定毛蕊异黄酮葡萄糖苷含量;紫外分光光度法测定总皂苷及总黄酮含量.考察不同产地三年生的黄芪药材,陕西产的黄芪甲苷含量最高,其次是内蒙古、山西、甘肃;毛蕊异黄酮葡萄糖苷含量从高到低依次是甘肃、内蒙古、陕西、山西.考察不同生长年限的陕西黄芪,黄芪甲苷含量随生长年限增加先升后降,3年生黄芪中黄芪甲苷(0.162％)与总皂苷(4.28％)含量最高,随后逐渐下降;毛蕊异黄酮葡萄糖苷及总黄酮含量随生长年限增加逐渐递增,7年生黄芪中毛蕊异黄酮葡萄糖苷(0.045 2％)及总黄酮(0.584％)含量最高.若以黄芪甲苷或总皂苷为功效指标,建议选择3年生黄芪;若以毛蕊异黄酮葡萄糖苷或总黄酮为主要功效指标,建议优选6～7年生黄芪药材.
Explore the accumulation and distribution patterns of active ingredients in Astraga-lus membranaceus from different origins and growth years,providing a basis for effectively controlling the quality of Astragalus membranaceus.The content of astragaloside Ⅳ was de-termined using HPLC-ELSD,while Calycosin-7-O-β-D-glucoside was determined using HPLC-UVD.Total saponins and total flavonoids were quantified by ultraviolet spectropho-tometry.Among three-year-old Astragalus samples from different origins,Shaanxi exhibited the highest astragaloside Ⅳ content,followed by Inner Mongolia,Shanxi,and Gansu.The Calycosin-7-O-β-D-glucoside content ranked from highest to lowest as Gansu,Inner Mongo-lia,Shaanxi,and Shanxi.For Shaanxi Astragalus of different growth years,three-year-old sam-pies showed the highest astragaloside Ⅳ(0.162％)and total saponin(4.28％)contents,which subsequently declined.The Calycosin-7-O-β-D-glucoside(0.045 2％)and total flavonoid(0.584％)contents peaked in seven-year-old samples.For medicinal use targeting astragaloside Ⅳor total sap-onins,harvesting three-year-old Astragalus is optimal;for Calycosin-7-O-β-D-glucoside or total fla-vonoids,six to seven-year-old Astragalus is preferred.
