虻虫药材性状显微特征鉴别研究

目的:探索虻虫6种主流商品药材性状、显微鉴别特征。方法:药材性状比对,虻虫不同部位及刚毛显微特征测量和比对。结果:双斑黄虻体型较小,长度不超过14 mm,体壁碎片呈黄棕色或浅黄色,刚毛比其他虻虫细小;而其他5种昆虫体长均超过15 mm,体壁碎片多呈棕黑色或灰黑色。结论:虻虫正品药材双斑黄虻与其他5品种可以依据药材性状和体壁碎片颜色,刚毛的长度、基部直径等显微特征鉴别。

Shapes, properties and microstructures of gadfly

Objective : To search and identify the microstructure of medicinal properties of six kinds of gadfly. Method : The medicinal properties, different body parts and bristles microscopic characteristics were compared. Result : The two-spotted yellow gadfly had a smaller size. Its length no more than 14mm, body wall debris was yellow brown or pale yellow, the seta was smaller than that of the other gadflies; while the other five varieties' body lengths all exceeded 15 mm, and their body wall debris mostly were brown black or gray and black. Conclusion : The authentication between the two-spotted yellow gadfly and the other five varieties can be made by the microscopic characteristics of their medicinal properties, body wall debris colors, bristle lengths, and basal diameters.
