| 摘 要： | 牡丹皮和徐长卿皆为常用中药,均含有丹皮酚。丹皮酚具有降压、镇静等作用,对小鼠的实验性疼痛和由于电刺激或药物引起的惊厥具有止痛作用和抗惊厥作用。测定丹皮酚的方法有薄层-分光法、容量法等,但较费时。根据丹皮酚易为溴取代的性质,我们研究了用库伦滴定法进行测定,同时比较和改进了生药提取方法,简化操作,缩短了分析样品时间,从而建立了较简便的测定牡丹皮和徐长卿中丹皮酚的方法。

| Abstract: | Goulometric titration of paeonol with electrolytically generated bromine was studiedThe titration was carried out in a mixture of 1 M KBr-2N HCI and bromine was generated at the anode, paeonol reacted with one mole of bromine with an n value of 2. This method was applied to the analysis of paeonol in Paeonia suffruticosa Andr. vand Pycnostelma paniculatum (Bunge) K. schum, and satisfactory results were obtained.The advantages of this method are simple, rapid and accurate, it can be used to analyze small amount of sample. |
