排风藤的生药鉴别
JOURNAL OF CHINESE MEDICINAL MATERIALS(2009)
Abstract
目的:对排风藤(Solanum cathayanum Wu et Huang)进行生药鉴别.方法:采用原植物鉴别,药材性状、显微、理化鉴别,确定药材鉴别特征,采用RP-HPLC 法对番茄碱进行含量测定.结果:排风藤茎横切面表皮外侧具腺毛和非腺毛,中柱鞘部位有纤维断续成环带,维管束双韧型,韧皮部较窄,木质部宽广;粉末含草酸钙砂晶、非腺毛、导管和纤维;薄层色谱与对照番茄碱相应位置显相同颜色斑点,排风藤中番茄碱含量为0.24%.结论:分析总结了该药材性状、显微典型特征,建立了该药材中番茄碱含量测定方法,为制定排风藤药材质量标准及进一步开发利用该药物提供了依据.
