5种中药饮片及其免煎饮片有效成分的对照研究

Studies on the Active Components of Five Kinds of Chinese Crude Herbs and Samples Avoidable for Boiling

目的研究免煎饮片中有效成分的含量。方法采用现代分析方法对黄芪、白术、牡丹皮、巴戟天和葛根5种中药饮片及其由同批饮片生产的相应的免煎饮片中的黄芪多糖、苍术酮、白术内酯、丹皮酚、巴戟天甾醇和葛根总黄酮进行检测与分析。结果免煎饮片中黄芪多糖、苍术酮、白术内酯、丹皮酚和巴戟天甾醇含量较低,尤其是高分子黄芪多糖和挥发性有效成分苍术酮、白术内酯、牡丹酚含量更低,且含有较多杂质。结论免煎饮片的生产工艺与质控上有不足之处。

Objective: To detect the contents of the active components in five kinds of Chinese crude herbs and Samples Avoidable for Boiling(SAB). Methods: With modern technology, astraglin in Radix Astragali, atractylons and butenolide in Rhizoma Atractylodis Macrocephalae, paeonol in Cortex Moutan , sterols in Radix Morindae Officinalis and flavonoids in Radix Puerariae were detected and analyzed. Results: In SAB, the contents of astraglin, atractylone, butenolide, paeonol and sterols were low, especially the high molecular polysaccharides and volatile active components of atractylone, butenolide and paeonol. Meanwhile, more impurities were found in SAB. Conclusion: There are some defects in the production techniques and quality control of SAB.
