TITLE: | |
摘要: | 目的:研究煎药机不同煎煮方法对药材有效成分煎出率的影响。方法:选用主要成分明确、不同部位(根茎类的丹参、果实种子类的栀子和叶类的桑叶)的3种中药饮片,测定3种煎药方法(不浸泡煎煮25 min、浸泡30 min后煎煮25 min、浸泡30 min后煎煮50 min)煎煮各饮片后煎出液中各有效成分(丹酚酸B、栀子苷、芦丁)的含量并计算煎出率。结果:3种煎药方法下,丹参中丹酚酸B煎出率分别为41.9%、71.6%、62.1%,栀子中栀子苷煎出率分别为68.9%、72.2%、75.6%,桑叶中芦丁煎出率分别为36.4%、47.2%、56.2%。结论:栀子苷、芦丁煎出率随着煎煮时间延长略增加,丹酚酸B煎出率则随着煎煮时间延长略有降低。建议在采用煎药机煎药时,对于不同处方、不同部位、不同有效成分的药材应采取不同的煎煮时间。 |
ABSTRACT: | OBJECTIVE: To study the effects of different extraction methods of decoction machine on the extraction rate of effective components in medicinal materials. METHODS: 3 kinds of TCM decoction pieces with clear component and different parts (rhizome Salvia miltiorrhiza, fruit Gardenia jasminoides and leaves Morus alba) were selected and decocted by 3 decoction methods (decocting for 25 min, decocting for 25 min after soaking for 30 min, decocting 50 min after soaking for 30 min). The contents of effective components (salvianolic acid B, jasminoidin, rutin) were determined and decocting rates were calculated. RESULTS: Using 3 decoction methods, decocting rates of salvianolic acid B from S. miltiorrhiza were 41.9%, 71.6%, 62.1%; those of geniposide from G. jasminoides were 68.9%, 72.2%, 75.6%; those of rutin from M. alba were 36.4%, 47.2%, 56.2%, respectively. CONCLUSIONS: The decocting rates of geniposide and rutin are slightly increased with decoction time prolongs, while the decocting rate of salvianolic acid B is decreased with decoction time prolongs. It is suggested to adopt different decoction time for medicinal materials of different prescriptions, different parts and different effective components when using decoction machine. |
