河北安国市场砂仁及其混伪品的性状及微性状鉴别研究

Identification of Amomi Fructus and Its Adulterate Products by the Characteristic and Micro-morphology in Hebei Anguo Market

目的通过对安国市场上砂仁的性状及微性状鉴别,将砂仁与其混伪品进行区分,规范安国市场上砂仁的品种,同时为砂仁的鉴别提供依据。方法用体视显微镜观察砂仁果皮、种子以及种子的横、纵切面,使用景深合成技术,得到砂仁各部位微性状特征图。测量果实的长度、直径以及每室的种子粒数,用SPSS软件进行分析。结果安国市场上存在大量的砂仁伪品,国产的掺有疣果砂仁,进口的大部分为长序砂仁。砂仁与伪品在果皮、种子及断面微性状存在明显区别。果实的长度和直径有统计学差异,每室的种子粒数无显著差异。结论性状和微性状鉴别能准确、快速的区别砂仁及其混伪品。

OBJECTIVE Identifying the morphological properties and micro-characteristics of Amomi Fructus in order to distinguish the real from the false of Amomi Fructus,so as to provide some theoretical basis on Amomi Fructus identification.METHODS Through a stereomicroscope,observing the interior and exterior surface of the pericarp,seeds of Amomi Fructus,as well as the shape,the surface texture,the transverse section and the vertical section of the seeds.Using the technique of depth synthesis to get characteristic graphs of all the sections.Measuring the length and diameter of the fruit and the number of seeds particles in each chamber,analyzing the results on SPSS software.RESULTS Given that the TCM market is filled with amounts of fake Amomi Fructus,the domestic Amomi Fructus were mixed with muricarpume Elm,while most of the imported with thyrsoideum Gagnep.Acording to the differences in morphological properties,and the statistical measurements of length of fruits,there is a method which can be used to differentiate.CONCLUSION The method of analyzing the morphological properties and micro-characteristics of Amomi Fructus can be applied to identify Amomi Fructus.It is more accurate and faster.
