摘要
目的 :最近的植物学研究表明 ,道地药材凤丹皮的原植物凤丹 (杨山牡丹 )与牡丹是两个不同的植物学种。本文从药学的角度研究来源于两种不同植物的药材在质量上的差别。方法 :用HPLC法对同一时间和地域采集的凤丹 5个样品 (包括野生和栽培 )、牡丹 4个样品以及 6个购买的商品药材进行了芍药苷和丹皮酚的含量测定 ,并考察了其中所含的芍药苷类和丹皮酚类主要成分的情况。结果与结论 :①凤丹和牡丹在有效成分含量和各种成分构成上无明显差异 ,但考虑到二者的形态差别 ,建议药典将牡丹皮的来源确定为凤丹PaeoniaostiiT .HongetJ.X .Zhang和牡丹P .suffruticosaAndrews;②在药材的采收加工和储藏的过程中 ,有丹皮酚苷类向丹皮酚转化的趋势 ,因而在以丹皮酚的含量评价药材或成药的质量时应予注意。
Objective: To study the contents of main chemical compounds, such as, paeonol, paeoniflorin and their similar compounds in structure in Paeonia ostii and P.suffruticosa , and to find their quality difference. Method: HPLC was used. The contents of paeoniflorin and paeonol in 9 collected samples, 5 from P.ostii and 4 from P.suffruticosa , and 6 herb samples bought from different areas were analyzed. The rough contents of 3 paeonol similar compounds and 2 paeoniflorin similar compounds were investigated. Result and Conclusion :①There is no obvious difference in the contents of paeonol and paeonoflorin and the constitution of other main compounds between P.ostii and P.suffruticosa .Since they belong to different botanic species, it is suggested that both P.ostii and P.suffruticosa should be recorded in Chinese Pharmacopoeia as the origin of Cortex Paeoniae. ② The glucosides of paeonol might change to paeonol in the course of the collecting and processing of the herb. Therefore when the contents of paeonol is used as the standard to evaluate the quality of the material and patent medicine, the attention should be paid to the transformation mentioned above.
