摘要：目的:比较龙胆科龙胆属秦艽组的6种药用植物(秦艽Gentiana macrophylla Pall.、粗茎秦艽G.crassicaulis Duthie ex Burk.、麻花秦艽G.straminea Maxim.、小秦艽G.dahurica Fisch.、黄管秦艽G.officinalis H.Smith和管花秦艽G.siphonantha Maxim.ex Kusnez.)的药用形态及显微鉴别特征,为中药秦艽真伪鉴别提供依据。方法:采用徒手切片法对主根的上、中、下3个部位分别做横切片,进行显微观察;根粉末经水合氯醛加热透化后显微观察。结果:粗茎秦艽根上、中、下部都没有中柱裂分。秦艽、小秦艽、黄管秦艽的根只有上部有中柱裂分;麻花秦艽和管花秦艽的根上、中、下都是完全分离的小根纠聚在一起。粉末鉴别中,小秦艽、麻花秦艽和管花秦艽都有大量的厚壁细胞,但形状不同。其他3个种没有发现厚壁细胞。结论:秦艽组6种药用植物根的形态组织显微结构有较大差异,可为中药秦艽的鉴别提供依据。
Objective： To provide evidences for the identification of Gentianae Macrophyllae Radix by comparing the morphological characteristics of six species of Sect. Cruciata（ Gentiana macrophylla,G. crassicaulis,G. straminea,G. dahurica,G. officinalis and G. siphonantha）. Methods： By microscope,the tissue characteristics with freehand section of the upper,middle and lower of root and the powder characteristics with chloral hydrate were studied. Results： The vascular cylinder of G. crassicaulis was not split. The vascular cylinder of G. macrophylla,G. dahurica and G. officinalis,were only split in the upper part. The root of G. straminea and G. siphonantha wre completely divided into several smaller roots twisting together. There were a lot of thick walled cells in the powder of G. dahurica,G. straminea and G. siphonantha,but their shapes were different. No thick walled cells were found in the other three species. Conclusion：There are obviously differences among the microscopic morphological characteristics of root of six species of Sect. Cruciata,which can provide the basis for identification of Gentianae macrophyllae Radix.
