【摘要】 目的以动物药残留毛的显微特征为依据,对中药蝉蜕及其易混淆品进行鉴别。方法对黑蚱、蟪蛄、焰螓蝉的干燥蜕壳粉末进行显微制片观察,结合图像测量软件提取刚毛的直径、长度、毛窝直径等显微特征参数,进行比较分析。结果黑蚱、蟪蛄、焰螓蝉的虫体体表刚毛在形态、颜色、直径、长短等方面以及毛窝的形态、颜色、大小等方面均具鉴别特征,并将之汇集成蝉蜕及混淆品的刚毛鉴定检索表。结论利用动物药残留毛的显微特征差异,可以达到蝉蜕真伪鉴别的目的。更多还原

【Abstract】 OBJECTIVE To identify Periostracum Cicadae and its two counterfeits by observation of microscopic characteristics of setae in animal drugs. METHODS The shapes and colors of dried exuviae powders for Cryptotympana pustulata (Fabricius), Platypleura kaempferi (Fabricius) and Tibicen flammatus (Dist.) were observed, and the diameter of trichopore length and the diameter of setae were measured and compared. RESULTS The different features of setae between genuine and counterfeits could be complied as a useful microscopic identification key of Periostracum Cicadae from its forged products. CONCLUSION The method of identifying animal drugs from their counterfeits by the remnant setae is confirmed.更多还原
