目的:对三花莸进行系统的生药学及微性状特征研究。方法:采用植物形态鉴别、性状鉴别、显微鉴别对三花莸进行系统的生药学研究;采用微性状鉴别对三花莸叶的表面、果实、种子进行微性状特征研究。结果:植物形态以茎、叶、花和果实的形态为其主要鉴别特征;性状以茎叶的表面颜色及大小、花序和果实类型、气味为其主要鉴别特征;茎的横切面以厚角细胞、内皮层细胞、纤维束、维管束等为其主要鉴别特征;叶以表皮细胞的形态、气孔类型,叶肉细胞的排列方式、维管束类型、腺鳞、腺毛、非腺毛等为其主要鉴别特征;粉末以表皮细胞的形态、气孔类型、腺鳞、腺毛、非腺毛、导管等为其主要鉴别特征。结论:本研究可为三花莸的品种鉴别、生药学研究、质量标准的制订及进一步开发利用提供一定的参考。
OBJECTIVE: To study systematically the pharmacognosy and micro-traits of Sanhuabao. Methods: The morphological characterization, traits identification and microscopic identification were used to systematically study the pharmacognosy of Sanhua. The micro-traits of the surface, fruit and seeds of Sanfoa macrophylla were identified by micro-traits identification. Results: The morphological characters of stem, leaf, flower and fruit were the main distinguishing traits. The stem color and size, inflorescence and fruit type and smell were the main distinguishing traits. The cross section of stem was thick-angle cell , Endodermis cells, fiber bundles and vascular bundles were the main distinguishing features. The main forms of epidermal cells, stomatal types, arrangement of mesophyll cells, vascular bundles, adenosquamous cells, glandular trichomes and non-glandular trichomes Identification features; powder to epidermal cell morphology, stomatal type, adenosquamous, glandular hair, non-glandular hair, catheters as its main distinguishing features. Conclusion: This study may provide a reference for identification of species, pharmacognosy research, quality standard formulation and further development and utilization.
