Abstract

Astragali Radix is derived from roots of Astragalus membranaceus var. mongholicus and A. membranaceus. The exhaustion of wild Astragali Radix has made cultivated Astragali Radix possess the commercial market of Astragali Radix. So the ecological environment of cultivated Astragali Radix should be investigated through field survey. Through investigation, we found that A. membranaceus var. mongholicus are cultivated in Hengshan mountain of Shanxi province, Longnan of Gansu province, south of Inner Mongolia and Qinghai provinces. A. membranaceus var. mongholicus is almost planted on the plain, except in Shanxi province it grows on the sunny side of the mountain. What is more, soil type, elevation, annual temperature and annual rainfall of these locations are different. So the ecological environments of cultivated location of Astragali Radix are different from each other. A. membranaceus is wild in Heilongjiang and northeast of Inner Mongolia, but the resource is drying up. It is also planted in few places of the provinces of Shanxi, Shandong, Hebei, Gansu, but cultivated scope of A. membranaceus is smaller than A. membranaceus var. mongholicus. . So A. membranaceus var. mongholicus possesses large part of Astragali Radix market. In market, there exists no unified specification fro slices of Astragali Radix, and specification of prepared slices will influence the contents of chemical components. Through investigation, different kind of prepared slices can be collected and compared, this provides evidences for quality control of prepared slices. Through investigation, five different specifications of prepared slices were found in market. The distributions of some specification of prepared slices are specified, like transverse prepared slices prepared from A. membranaceus only found in Heilongjiang province. Transverse prepared slices possess half part of prepared slice market, and can be used to identify original plant of Astragali Radix. So transverse prepared slices should be the unified specification of Astragali Radix.
