目的：对苦苣菜进行生药学鉴定。方法：采用药材基原鉴定、性状鉴定、显微及理化鉴别方法。结果：苦苣菜主要鉴别特征：药材茎黄绿色，具纵棱，基部略带淡紫色，断面中空。叶互生，皱缩破碎，羽状深至全裂，裂片边缘有小尖刺；叶表皮以不等式气孔为主；叶柄中为外韧型维管束，韧皮部周围细胞含棕色颗粒物；粉末中非腺毛、方晶、乳汁管、具缘纹孔等特征明显。主要含有黄酮类成分，乙醇提取液在206、232和333 nm处有明显的紫外吸收。结论：性状和显微鉴别及理化鉴别方法能有效鉴别苦苣菜，为制定苦苣菜的质量标准和有效利用提供鉴别依据。

Objective:To identifySonchus oleraceus L. by pharmacognosy.Methods:The means of morphological, macroscopical, microscopical, physical and chemical identification were adopted for the pharmacognostic study.Results: The main characteristics of the crude drug are as follows: The stem of herbs is yellowish green, with longitudinal ribs, and the base of crude drug is lavender, with hollow fracture surface. Leaves grow alternate, shrunken and broken, feathered deep to the whole crack, lobe margin with small spikes. Anisocytic stomata apparatus distribute in leaf epidermis. Petiole vascular is collateral bundle. The cell contains brown particles around the phloem. There are obvious non-glandular hairs, columnar crystal, secretory cavity and pitted vessel in powder form. The herb mainly contains lfavonoid compositions, the alcohol extract has obvious ultraviolet absorption at 206.5, 232, 333 nm.Conclusion:The means of morphological, microscopical, physical and chemical identiifcation can effectively identify the crude drug, and the pharmacognostic characteristics of the herb can provide basis for establishing the quality standard ofSonchus oleraceus L.
