摘　　要：柳叶菜科苗药柳叶菜和易混品粉花月见草二者为同科不同属的多年生草本植物,植物形态特征相似,但治疗功效迥异,临床用药容易将二者混淆使用,从而影响疗效。本研究对柳叶菜和粉花月见草全株进行原植物鉴别、性状鉴别及显微组织特征鉴别,确定3种不同的薄层色谱展开系统,对关键参数进行优选并验证。结果表明,柳叶菜和粉花月见草在原植物、性状、显微方面有区别;在3个展开系统的薄层色谱中,二者的供试品色谱与山奈酚对照品、槲皮素对照品色谱各自在相应位置上显示相同颜色的特征斑点,Rf值符合规范且一致。研究表明,生药鉴别可以有效区别柳叶菜和粉花月见草。Epilobium hirsutum L.,as Onagraceae Miao medicine,and adulterants of Oenothera rosea L.are perennial herbs of different generas in the same family,with similar morphological characteristics,but different therapeutic effects,which were easy to confuse the two in clinical use,thus affecting the curative effect.In this study,the original plant identification,character identification and microstructure characteristics identification of Epilobium hirsutum L.and Oenothera rosea L.were carried out.Three different TLC development systems were determined,and the key parameters were optimized and verified.The results showed that there were differences in the original plant,characters and microscopic aspects between Epilobium hirsutum L.and Oenothera rosea L..In the TLC of three unfolded systems,the chromatography-tested products of both were compared with kaempferol and quercetin.The spectra showed the same color feature spots at corresponding positions,and the Rf values were consistent with the standard.The study showed that the identification of crude drugs could effectively distinguish Epilobium hirsutum L.from Oenothera rosea L..
