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

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.
