We carried out a field survey of original plants of Rhei Rhizoma (Dahuan, 大黄) and of several other crude drugs growing in the southeast of Qinghai province (青海省), China. The quality of Rhei Rhizoma was also investigated. 1. Three types of Rheum plants i.e. R. tanguticum MAXIM, ex BALF., R. palmatum L. and their intermediate grew wild in the southeast of Qinghai province. 2. Data of the general test of JP XII, the sennoside A and B contents and observations of the shape and smell suggested that the original plants of Rhei Rhizoma produced in this area included more than 2. 3. Some Rhei Rhizoma imported from Sichuan province (四川省) might be product of Qinghai province (青海省), because a factory for preparation of crude drugs governed by 青海省班瑪県外貿公司 in Baima (班瑪) said that it commercially produced Rhei Rhizoma by request from 四川省外貿公司. 4. Original plants of several other kinds of crude drugs, i.e. Cordyceps (冬虫夏草), Paeonia Rubra Radix (川赤芍) and Glycyrrhiza Radix (甘草) and their growth environment in habitat were also investigated.
