目的:对龙胆科三种地格达类蒙药材扁蕾、椭圆叶花锚、肋柱花的粉末及茎的横切片进行显微鉴别研究,为地格达类蒙药材的鉴定和开发利用提供参考。方法:用光学显微镜观察。结果:在三种蒙药材粉末中观察到了相同的气孔轴式、螺纹导管和纤维,及各不相同的花粉粒、叶表皮细胞和腺毛。在三者的茎横切片均可见表皮、皮层、韧皮部、木质部和髓,但构造形态有较大差异。结论:以上显微特征对龙胆科地格达类蒙药的鉴别具有一定意义。
Objective:Study the microscopical characters of Gentianopsis barbata,Halenia elliptica and Lomatogonium carinthiacum which are the resource of "Digeda",to provide the reference for the identification and utilization of this Mongolian medicine.Methods:Microscopic identification.Results:In the three kinds of Mongolian medicinal powder,stomata type,spiral vessel and fiber have the same characteristic;pollen grain,epidermal cells,trichome have the different characteristic.All the three kind of the stem have epidermis,cortex,phloem,xylem and pith,but their structure and characteristic is different.Conclusion:The microscopic characteristics of the three Digeda species is tipycal.
