目的 探索评价曼陀罗和毛曼陀罗花的最佳采收期的方法。方法 将两种曼陀罗花的生长发育过程进行量化,与Logistic生长曲线方程拟合,建立数学模型,运用有序聚类分析法将其生长过程划分不同采收期,以活性成分为指标,对两者最佳采收期进行界定。结果 两种曼陀罗花的生长过程与Logisitic生长曲线方程拟合良好,有序聚类分析后将其花的生长发育过程划分为5个阶段,依此确定的最佳采收期与以往研究中药材最佳采收期方法不同。结论 该研究中药材最佳采收期的方法值得进一步研究并推广。

Objective To establish the new method for evaluating the best harvest period of Datura stramonium and Datura innoxia flowers. Methods The growth processes of D. stramonium and D. innoxia flowers were quantified and fit with Logistic growth curve equation, so as to set up a mathematical model, then using cluster analysis method to divide the orderly growth process into different collection periods. The active ingredient was used as the index of the two to optimize the best harvest period. Results The growth of D. stramonium and D. innoxia flowers and Logisitic growth curves fit well. After cluster analysis, orderly growth and development of the flowers were divided into five stages so that the differences between the present best harvest period and the best harvest period of the traditional Chinese medicinal materials (TCMM) in the past years were observed and optimized. Conclusion The available way to study the harvest period for TCMM is worthy to be further studied and promoted.
