Title: Analysis of Astragaloside IV from Astragalus membranaceus (Fisch.) Bge.by TLCS
Abstract: This paper studied on the contents of Astragaloside Ⅳ from Astragalus membranaceus(Fisch.) Bge.of wild and cultivation in different origin and different vegetation,determined optimal picking time of Astragalus membranaceus(Fisch.) Bge.to develop and use better resources of Astragalus membranaceus(Fisch.) Bge.,providing theoretical foundation,establishing methods of analysis for Astragalus membranaceus(Fisch.) Bge.,providing reference data about system of quality evaluation for Astragalus membranaceus(Fisch.) Bge.,expanding medicinal herbs resource of Astragalus membranaceus(Fisch.) Bge.The contents of Astragaloside Ⅳ from Astragalus membranaceus (Fisch.) Bge.of wild and cultivation in different origin and different vegetation period were determined by TLCS.The linear range was 1.1—5.5μg(R2=0.998,n=3) for Astragaloside Ⅳ.The average recovery(n=3) was 100.50%,RSD=2.19%.The content of Astragaloside Ⅳ from Astragalus membranaceus(Fisch.)Bge.of LINJIANG reached 1.195% on October 20th,1.164% on October 15th.The content of Astragaloside Ⅳ in different place was GansuJilin LinjingNeimengHeilongjiangJinlin ChangchunHebei.The content of Astragaloside Ⅳ was a descent of storing after six months.The method was simple,accurate and reliable.This method established the best harvesting period of Astragalus membranaceus(Fisch.) Bge.in the middle ten days and the last ten days of October.The authors may replace Astragalus membranaceus (Fisch.) Bge.of wild with Astragalus membranaceus(Fisch.) Bge.of planting base and to develop and use better resources of Astragalus membranaceus(Fisch.) Bge.providing foundational foundation.
