不同月龄蚂蟥内在品质及最佳采收期研究

Qualities of Whitmania pigra in different-month-age and best harvest time

目的:比较不同月龄蚂蟥内在品质及生长的差异,为其药材质量控制及最佳采收期的确定提供理论依据。方法:水分、醇溶性浸出物、总灰分、酸不溶性灰分、抗凝血酶活性测定都参考2005年版《中国药典》;结果:各月龄采集的蚂蟥其品质均符合国家药典标准,其中醇溶性浸出物含量以9月龄蚂蟥最高,6月龄的其次,而且9月龄蚂蟥与4月龄、7月龄、11月龄的蚂蟥有显著性差异(P<0.05);抗凝血酶活性含量以6月龄蚂蟥最高,10月龄其次,而且6月龄与4月龄、5月龄有显著性差异(P<0.05),与其他月龄无显著性差异;6月龄的蚂蟥干重最高,与其他月份采集的有显著性差异(P<0.05)。结论:江浙一带人工养殖的蚂蟥最佳采收期为11月份(即6月龄)。

Objective:Dynamic changes of quality and growth of Whitmania pigra were investigated to provide theoretical basis for quality control and determination of optimal harvest time.Method: The contents of moisture,ethanol-soluble extractive,total ash,and acid-insoluble ash,as well as antithrombin activity were determined according to Chinese pharmacopoeia(2005 edition).Result: Qualities of W.pigra collected from different growth stages met the standards of Chinese pharmacopoeia(2005 edition).The highest amount o...
