摘要
目的:研究蓝花桔梗和白花桔梗中总皂苷的积累动态,确定蓝花桔梗和白花桔梗的最佳采收期。方法:按2005年版《中华人民共和国药典》中所规定的方法对不同时间采集的桔梗中的总皂苷含量进行测定并进行了聚类分析。结果:二年生蓝花桔梗和白花桔梗分别在9月20日、9月30日产量最大的同时根内的总皂苷含量也最高,为最佳采收期。结论:本方法简便、准确、可行。
AIM: To research the development of the content of total saponin in Platycodon grandifloeum (Jacq.) A. DC. and Platycodon grandifloeum (Jacq.) A. DC. var. Hort so that the best harvest time was found. METHODS : Using the methods of cluster analysis and according to the examination method ruled in the 2005 version 〈 The People g Republic of China Prannacopoeia〉, the content of total saponin in Platycodon grandiflorum in difierent harvest time was compared. RESULTS: Platycodon grandifloeum (Jacq.) A. DC and Platycodongrandifloeum (Jacq.) A. DC. var. Hort respectively On September 20, September 30 are the largest yield and the largest content of total saponin in root, that time is the best harvest time. CONCLUSION: The method is simple, accurate and reliable.
