簕欓根生药学研究

Pharmacognostical Study on Radix Zanthoxyli avicennae

目的:对簕欓根进行生药学研究,为簕欓根的临床利用和开发提供依据。方法:采用来源鉴别、性状鉴别、显微鉴别和理化鉴别方法等。结果:簕欓根的外皮易剥落,皮部与木部易分离,木部有环纹;根横切面有3～4轮偏心性、同心环状年轮,导管沿径向排列,橙皮苷结晶多,有方晶;粉末中淀粉较少;理化结果表明簕欓中含有黄酮、生物碱等主要活性成分。结论:该研究为簕欓根药材的深入研究和开发利用提供了理论依据。

Objective： To establish pharmacognostical methods on Radix Zanthoxyli avicennae so as to provide scientific evidence for clinical application and development of Zanthoxylum avicennae（Lam.）DC..Method： The original plant identification,morphological,microscopic identification are adopted to identify original plant Radix Zanthoxyli avicennae by systematic identification of pharmacognosy.Result： The exodermis is easily peel off,the cortex is easily separate from the woody part,there are some annulations in the woody part and 3~4 rounds of eccentric and concentric annual rings in the transaction,the vessels are radial orientation,the aurantiamarin crastals are numerous,solitary crystal sometimes can be seen,and there are little starch in the powder.Physic-chemical experiment show that it is containing some active components such as flavones and alkaloid etc.Conclusion： The results of the study serve as scientific evidences for clinical application and development of Radix Zanthoxyli avicennae.
