本文运用体视显微镜观察了益智仁、草蔻仁,白蔻仁三种种子的立体形态,用电镜扫描观察了三种种子表面纹理。结果:三种种子的立体形态、种脐均不同。体视镜下均可见由种脐至合点方向的平行细密纹,而在平行细密纹上的纹理则各不同。这些不同点可以按条件不同选取作药品鉴别标准。 In this paper, the three-dimensional morphology of three kinds of seeds, ie, Alpinia oxyphylla, Euphorbia pulcherrima, and Bletilla striata, was observed by stereomicroscope. The surface texture of three seeds was observed by electron microscopy. Results: The three-dimensional seed morphology and umbilical were all different. Under the stereoscope, parallel fine lines from the umbilical to the joint are visible, while the textures on the parallel fine lines are different. These differences can be selected according to the conditions for drug identification standards.
