目的:研究山茱萸中齐墩果酸、熊果酸和马钱素的含量以及药材干果得率在成熟过程中的变化规律。方法:于成熟期不同阶段采收山茱萸,利用微管液相色谱法及高效液相色谱法测定熊果酸、齐墩果酸与马钱素的含量,称量干果重量。结果:山茱萸果实成熟过程中干果得率逐渐提高,熊果酸、齐墩果酸含量逐渐降低后至稳定状态,而马钱素含量则逐渐升高。结论:由上述因素综合考虑,传统的采收时间是合理的。
OBJECTIVE: To study the content of oleanolic acid, ursolic acid and loganin in Cornus officinalis and the variation of dried fruit yield during the ripening process. Methods: Cornus officinalis was collected at different stages of maturity. The contents of ursolic acid, oleanolic acid and loganin were determined by microtube liquid chromatography and high performance liquid chromatography. The weight of dried fruit was weighed. Results: The yield of dried fruits increased gradually during the ripening process of Fructus Corni fruit. The contents of ursolic acid and oleanolic acid gradually decreased to a steady state while the content of loganin increased gradually. Conclusion: Considering the above factors, the traditional harvesting time is reasonable.
