Quality Variation of Astragalus membranaceus var.mongholicus with Different Growing Years in Zizhou County
摘要
Abstract
Objective:To compare the content and reveal the variations of active components at the early and late dormancy stages of Astragalus membranaceus var.mongholicus growing for different years in Zizhou County,so as to determine the optimal harvesting time.Methods:The random sampling method was employed to collect 8 batches of A.membranaceus var.mongholicus samples in dormancy and growing for different years in Zizhou County.With the content of astragaloside Ⅳ,calycosin-7-O-glucoside,and water extract as evaluation indexes,the quality of the samples was compared by the hierarchical cluster analysis(HCA).Results:With the increase in growing years,the content of each component presented regularly dynamic changes.The content of astragaloside Ⅳ and calycosin-7-O-glucoside peaked in the samples of 5 years old,being 0.166%and 0.079%,respectively.The content of water extract was the highest(21.290%)in the 7-year-old samples.The content of astragaloside Ⅳ significantly decreased at the late dormancy stage compared with that at the early dormancy stage,and the decrease rate increased year by year,being the highest(54.09%)in the 7-year-old samples.The content of calycosin-7-O-glucoside and water extract increased at the late dormancy stage,with the largest increases(145.83%and 18.40%,respectively)in the 5-year-old and 7-year-old samples,respectively.Conclusion:The accumulation of active components in A.membranaceus var.mongholicus growing in Zizhou County were affected by the growing years and harvesting time,presenting inconsistent changes.With calycosin-7-O-glucoside as the evaluation index,the 5-year-old A.membranaceus var.mongholicus plants at the late dormancy stage were recommended for harvesting.With astragalosideⅣ as the evaluation index,the 5-year-old plants at the early dormancy stage were recommended for harvesting.With both astragaloside Ⅳ and calycosin-7-O-glucoside as evaluation indexes,the 6-year-old plants at the early harvesting stage were recommended for harvesting.关键词
