青葙子为苋科青葙子属植物青葙(Celosia argentea L.)的种子。由于其体积较小,直径1～2mm,用眼睛不易直接鉴别,因此各地常有混淆品出现,特别是同科苋属植物的种子,因体积和外形均与青葙子相似,故不易区别。另外还有藜科植物藜的种子,在部分地区也混同青葙子入药。鉴于此,将它们的种子置于扫描电镜下观察,则易于区别。材料和方法材料青葙(Celosia argentea L.);鸡冠花(C cristata L.);小苋 The green barnyardgrass is the seed of Celosia argentea L.. Because of its small size, diameter of 1 ~ 2mm, with the eyes is not easy to identify directly, so everywhere there are often confusion products, especially the seeds of the same family of plants, because the volume and shape are similar to the green barley, it is not easy to distinguish. In addition, there are seeds of the wolfberry plant, and in some areas, they are also mixed with green wolfberry fruit. For this reason, their seeds are easily observed by scanning electron microscopy. Materials and Methods Materials Celosia argentea L.; C cristata L.;
