目的:研究华南龙胆的根、茎、叶、花的性状、显微鉴别特征,为其真伪鉴别及准确用药提供参考。方法:采用性状鉴别、显微鉴别的方法。结果:发现华南龙胆根无木栓层,皮层较宽,木质部类圆形,无髓部。茎表皮细胞木化,皮层较宽,韧皮部、形成层断续成环,导管径向由外向内渐小,髓部细胞多角形。叶横切面上下表皮均有蜡被层,主脉维管束1个,外韧型;叶表面片下表皮细胞多角枝状,不定式气孔。花瓣横切长条状,表皮细胞有的略呈乳头状突起,花瓣中有2～4个简单维管束,外韧型。结论:华南龙胆的性状及显微特征,可作为鉴别真伪及制定药材质量标准的参考依据。
Objective: To study the characteristics of root, stem, leaf and flower of Gentiana scabra in South China, and to identify the features by microscopic identification. Methods: Using traits identification, microscopic identification method. Results: Southern China gentian roots were found without cork layer, with a wide cortex and a round xylem section without pulp. Stem cell epidermal cells, wide cortical, phloem, the formation of intermittent ring, the radial catheter from the outside to the internal gradually smaller, polygonal pith cells. Leaf cross-section of the upper and lower epidermis are wax layer, the main vascular bundle 1, outside the tough type; leaf surface epidermal cells epidermal cells dendritic, infinitive stomatal. Petals transverse strip, epidermal cells slightly papillary protrusions, petals in 2 to 4 simple vascular bundles, external toughness. Conclusion: The characters and microscopic features of Gentiana macrophylla can be used as a reference for authenticating authenticity and formulating the quality standard of Medicinal herbs.
