市售乌梢蛇的微性状鉴别研究

目的 探寻一种简单有效的方法，以快速鉴别市售乌梢蛇的真伪。方法 通过微性状鉴定法，对市售乌梢蛇的真伪进行鉴别。结果 乌梢蛇在市场上的伪品有灰鼠蛇、滑鼠蛇、眼镜蛇、赤链华游蛇、白链蛇等。通过微性状鉴别研究发现，湖南和四川产乌梢蛇体背的单鳞蛇皮均呈紫黑色，腹部均呈淡蓝色，具杂乱分布的斑点群，且湖南产乌梢蛇中央纵线处为黄棕色，具整齐分布的黑色斑点群；乌梢蛇伪品的单鳞蛇皮在其色泽与斑纹上与正品具有明显差异。结论 微性状鉴别方法可有效且精准地鉴别市售乌梢蛇的真伪，弥补传统经验鉴别的不足。

Microscopic Characteristic Identification of Commercially Available Zaocys dhumnades(Cantor)

Objective To establish a simple and effective method for the identification of the authenticity of Zaocys dhumnades (Cantor). Methods The authenticity of Zaocys dhumnades (Cantor) was identified based on microscopic characteristics. Results The adulterants ofZaocys dhumnades (Cantor) sold on the market included Ptyas korros (Schlegel), Ptyas mucosus (Linnaeus), Najanajaatra Cantor, Sinonatrix annularis (Hallowell), and Dinodon septentrionalis(Gunther). The identification of microscopic characteristics showed purple black scales on the back of Zaocys dhumnades (Cantor); Zaocys dhumnades (Cantor) produced in Hunan, China, had a yellow brown longitudinal line in the center, with orderly distributed black spots, and the abdomen was light blue with scattered spots. There were significant differences in color and stripes of single-scale snakeskin between the adulterants and the genuine product. Conclusion Microscopic characteristic identification can effectively and accurately identify the genuine Zaocys dhumnades (Cantor) and make up for the shortcomings of conventional identification method.
