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 explore the method of evaluating the best harvest time of Datura stramonium and Datura metel. Methods The growth and development of two Datura flowers were quantified and fitted with the logistic growth curve equation to establish the mathematical model. The growth process was divided into different harvest periods by the method of orderly clustering analysis. The active ingredients were used as indexes, The best time to harvest between the two be defined. Results The growth of two Datura flowers fitted well with the Logisitic growth curve equation. After the cluster analysis, the growth and development of the flowers were divided into five stages. The optimal harvest period was compared with the previous study Chinese medicine best harvesting period different methods. Conclusion The study of Chinese medicine best harvest period of the method deserves further study and promotion.
