民族药旋花茄的生药学研究

Pharmacognostical Study on Solanum Spirale Roxb

目的:为进一步开发和利用茄科植物旋花茄(Sola-num spirale Roxb.)提供理论依据。方法:采用原植物鉴别、药材性状鉴别、显微及理化鉴别的方法。结果:其主要显微特征为:根韧皮部窄,细胞内含草酸钙砂晶;叶肉组织异面型,薄壁细胞中散有多数草酸钙砂晶及少量草酸钙簇晶;叶表皮附着不定式气孔及腺毛。粉末特征与组织特征相符。结论:为制定药材质量标准、研究和开发利用该药物资源提供了理论依据。

Objective: To provide theoretical basis for the study and development of Solanum Spirale Roxb.Methods: The micro,physical and chemical methods were used to distinguish the raw plant and its property and shape.Results: The tissue characteristics of the medical plant shows that its root phloem is narrow,its cell contains calcium oxalate crystal sand,its mesophyll tissue is a bifacial type with much calcium oxalate crystal sand and a little calcium oxalate cluster crystal scattered in its parenchyma cell and indeterminate stoma and gland hair on its leaf.Its powder characteristics are in line with its tissue characteristics.Conclusion: The study provides a theoretical basis for making the quality standard and for the study and development of the medicine material.
