药用黄芪馆藏标本资源的统计分析OA

The 2020 edition of the Chinese Pharmacopoeia contains Astragalus membranaceus(Fisch.)Bge.var.mongholicus(Bge.)Hsiao and Astragalus membranaceus(Fisch.)Bge.)as Radix Astragali native species,which have a wide range of ecological cultivation and diverse germplasm resources.However,in recent years,the reserves of wild Radix Astragali resources have declined sharply,and the cultivated astragalus germplasm is mixed.In order to fully understand the distribution characteristics of Radix Astragali germplasm resources in China,a search and statistical analysis of the specimen information of Radix Astragali collected in 12 digital herbarium at home and abroad were conducted in this paper,and 498 Radix Astragali specimens were obtained.The collection period was mainly distributed from 1951 to 1990 and from 2011 to 2020,among which 177 A.Mongholicus samples were collected mainly in Inner Mongolia,Shanxi,and Hebei.The elevation of the collection sites showed that most samples were collected at higher elevations in the early stage and at lower elevations in the later stage.Most specimens were collected at altitudes of 800-2 000 m.There were 321 samples of A.membranaceus collected mainly from Shanxi,Sichuan,and Xinjiang.Compared with A.Mongholicus,the number of specimens of A.membranaceus collected at different altitudes during the whole period was more average.By searching and identifying the specimen information of Radix Astragali recorded in digital herbarium,basic data for understanding the distribution,classification and location of authentic producing areas of Radix Astragali resources were provided.
