目的研究重庆金佛山地区玄参在不同采收期的质量变化规律,明确最佳采收期。方法自11月初到次年1月初,间隔15天左右采集样品,按药典要求测定灰分、浸出物、哈巴苷和哈巴俄苷含量等质量指标。结果供试样品中浸出物含量变化平稳;哈巴苷和哈巴俄苷含量以12月为高;总灰分及酸不溶性灰分以12月至次年1月初较低。结论总体质量评价表明,重庆市金佛山地区的玄参以12月内采收为宜。
Objective To study the quality variation of figwort figwort (Scrophulariaceae) in different harvesting periods in Jinfo Mountain, Chongqing, and to find out the best harvesting period. Methods From early November to early January of the following year, samples were collected at intervals of about 15 days, and the quality indexes such as ash, extract, hababen and habazone glycosides were determined according to the requirements of the pharmacopoeia. Results The contents of extracts in the test samples changed smoothly. The contents of hababoside and harpagoside in December were high, and the total ash and acid-insoluble ash were lower from December to early January. Conclusion The overall quality evaluation shows that Scrophulariaceae collected from Jinfo Mountain in Chongqing is suitable for harvesting in December.
