| 摘 要： | 运用形态解剖学和薄层色谱鉴定的方法,对植物药珠芽景天（Sedum bulbiferumMakino）进行了鉴定研究。结果显示该植物药鉴别特征明显,如茎横切面的皮层外侧及中柱薄壁组织散布有紫红色细胞,髓部细胞较小,壁不增厚;叶下表皮气孔密布,常可见2个（有时3个）相距较近;薄层色谱中具多个特征性荧光斑点。文中描述了该植物药材的性状、显微与薄层色谱特征,还与同属近缘植物药垂盆草、佛甲草、凹叶景天进行了薄层色谱比较,并结合四者茎的显微结构,探讨了相互之间的亲缘关系。研究结果为珠芽景天的应用提供了可靠的鉴定依据。

| Abstract: | We used macroscopic and microscopic observation methods and TLC technique to determine the pharmacognostical characteristics of the crude medicine Zhuyajingtian(Sedum bulbiferum Makino) for identification purpose.The results showed that identification cha-racteristics of this drug were distinctive.For example,purplish-red cells were observed in the outer cortex and the parenchyma of stele in the stem cross section,pith cells were smaller with thin walls,the lower epidermis of the leaf was covered with stoma... |
