摘要
目的:建立3种栽培红豆杉(云南红豆杉南方红豆杉曼地亚红豆杉)的生药鉴别方法,为其深入研究提供实验数据。方法:采用原植物形态鉴别、药材性状检索、组织横切、粉末显微观察及薄层层析方法对其进行生药初步研究。结果:其叶横切面特征三者叶表皮细胞的形状、大小和排列均不一样,叶中脉形状不同,所含草酸钙砂晶及色素物多少有差异。枝横切面特征中韧皮部细胞形状和排列松紧不一,木射线细胞中内含物仅云南红豆杉有。粉末特征中三者所含石细胞、草酸钙砂晶、树脂道的多少、大小和形状均有差异。薄层色谱图中,斑点颜色和位置有不同之处,可作为鉴别依据。结论:通过对3种红豆杉的生药学研究表明,3种栽培红豆杉在原植物形态、药材性状及显微特征中均有一定的差异,将为这3种红豆杉药材的鉴别及进一步研究提供资料。
Objective： To constitute the Pharmacognosy research method about three cultured yews,in order to provide a data basis for deeper exploitation.Methods： Combined botanical identification,key of crude drug characters tissue transections,powder characteristics and TCL to study on pharmacognosy characters of these three yews.Result： The transections of leaves show that there are differences on the shape,size and rang of the epidermal cells,and the structure of leaf midvein is various,the calcium oxalate sand crystal and pigment are various more or less.The characters of stem transections are the differences on the size and rang of the phloem cells,the inclusions in xylem ray cells are only found from Taxus yunnanensis.The sclereids contain crystals,calcium oxalate sand crystals,the number,size,shape of resin ducts can be considered as the characters of powder.The difference between colors and locations of the TCL spots can be used as the identification characters too.Conclusion： This study can be taken as the references for deeper research and identification of these three cultured yews crud drugs.
