目的 通过对不同发育期草乌中主要成分的变化规律分析,探讨蒙医用药草乌药材的适宜采收期。方法 采用HPLC分别测定采收于发芽期、开花前期、开花期、枯萎期等不同发育期草乌6 种主要生物碱含量,并其总含量为指标,拟定草乌药材的适宜采收期。结果 蒙医用药草乌6种生物碱总量从发芽到枯萎呈现先升高后下降的趋势,其中开花前期含量最高,枯萎时含量达到最低。主要成分含量从高到低依次排序为开花前期、发芽期、开花期、枯萎期。结论 依据蒙医独特炮制方法及临床用药安全,拟定枯萎期为草乌药材最佳采收期,与蒙医传统采收期基本一致。
Abstract
OBJECTIVE To explore the optimum harvest time of the Mongolian medicine, Radix Aconiti kusnezoffii herbs, by analysis of the changes of the main components in different developmental stages. METHODS HPLC was used to determine the contents of the main alkaloids in 6 kinds of Radix Aconiti Kusnezoffii which were harvested in sprouting stage, early flowering stage, flowering stage and withering period, respectively. Taking the content of total alkaloids as index, the appropriate harvest time of Radix Aconiti kusnezoffii was determined. RESULTS From germination to withering period, the total alkaloids in the 6 kinds of Radix Aconiti Kusnezoffii displayed increasing and then decreasing trend. The highest contents existed in the early flowering stage and the lowest existed in the withering period. The contents of the main components were sorted from high to low in the early flowering stage, germination stage, flowering stage and withering period. CONCLUSION Based on the unique processing METHODS in Mongolian medicine and clinical medication safety, the withering period of Radix Aconiti Kusnezoffii is the best harvest time and this is consistent with the traditional Mongolian harvest period.
