《中国药典》1990年版收载的酸枣仁为鼠李科植物酸枣仁Ziziphus spinosa Ha.的干燥成熟种子。呈扁圆形或扁椭圆形,一面隆起,另一面较平坦,中间可见有一条隆起的纵线纹。表面紫红色或紫褐色。最近,在我司入库验收时发现酸枣仁中混有同属植物滇刺枣Z.mauritiana Lam.的成熟种子。经抽验检查发现该批混在正品中的滇刺枣是加入植物油炒制、烟熏后,至使外观颜色呈浅紫褐色或浅棕褐色。此批掺伪酸枣仁性状与正品极为近似,唯独颜色略浅。经用薄层层析鉴别,滇刺枣除分离出具有与正品酸枣仁相同的位置上显示2个相应颜色的斑点外,另外还发现3个主要斑点,各斑点均为深蓝色。望经营、生产、卫生
The Suanzaoren contained in the 1990 edition of the Chinese Pharmacopoeia is a dry mature seed of the Ziziphus spinosa Ha. It is oblate or oblong, one side is raised, the other side is flat, and there is a raised vertical line in the middle. The surface is purple or purple brown. Recently, in our company’s acceptance inspection, we discovered that the seeds of Suanzaoren were mixed with mature seeds of Z. mauritiana Lam. After random inspection, it was found that the batch of thorny jujube mixed in the authentic product was prepared by adding vegetable oil, frying, and smoking until the appearance color was light purple brown or light brown. This batch of adulterated Suanzaoren traits is very similar to the authentic, except that the color is slightly lighter. After identification by thin layer chromatography, in addition to the separation of spots with two corresponding colors on the same location as the genuine wild date, three main spots were found, each spot being dark blue.
