      (Study on the quality control of the fruit of Capparis spinosa L
      W. CHEN (Chen Weishen)*, Y. CHEN (Chen Yan), J. HE (He Jiang) (*The Xinjiang Uygur Autonomous Region Inst. of Pharm., Wulumuqi, Xinjiang 830004, China)

      Chinese J. of Lishizhen Trad. Med. & Pharm. 22(1), 133-134 (2011). Capparis spinosa L. is a plant with an important ecological function which is mainly growed in the sand of the Gobi desert. It has a huge root system which helps to maintain the humidity of the land. As a Uygur traditional medicinal herb, it is effective in curing diseases like rheumatism, toothache, and dysentery. However, hitherto only Capparis spinosa root has been used in the preparations. This wrecks seriously the resource of the herbal drug and its ecological function. Therefore, its fruits have recently been applied as replacement for the root in the preparations. Quality control of the fruits by TLC on silica gel with chloroform – methanol – formic acid – water 20:90:10:3. Detection by spraying with 5 % potassium iodobismuthate solution. The fingerprints were compared with the extracts from the root, taking one of the typical components, betaine, as the marker substance. In addition the fruits were identified based on their shape, size, surface colors, smell, and the sarcocarp; by microscopy and by determination of the moisture content.
