Investigation on the Medicinal Pteridophytes Resources in Yunnan Province

摘要(Abstract):

According to the specimens kept in herbarium of Yunnan University and relevant literature data,the medicinal pteridophytes resources in Yunnan Province were statistically studied.Results showed that,there were totally 345 species in 111 genera of 49 families of medicinal pteridophytes in Yunnan Province,most of them belonged to Polypodiaceae,Dryopteridaceae,Aspleniaceae,Pteridaceae,Thelypteridaceae,Selaginellaceae,Athyriaceae,Sinopteridaceae,Adiantaceae,Huperziaceae and Davalliaceae.Those pteridophytes had diversified medical effects,most of them were used for clearing heat and detoxication,the medical parts of most medicinal pteridophytes were their whole plants and rhizomes.The habitats of medicinal pteridophytes differed largely with a wide vertical distribution.The distribution of medicinal pteridophytes in Yunnan Province concentrated in Jinping,Gongshan,Guangnan and other counties,where there were great development values of pteridophytes resources.But due to the immature studies on the development of local medicinal pteridophytes resources,most of the species were only used as folk medicinal herbs.Therefore,a lot of problems needed to be solved.A field investigation should be carried out on the medicinal pteridophytes resources in Yunnan Province,their medicinal functions and values should be evaluated,the pharmacognostic studies should be enhanced,species of pteridophytes with obvious efficacies were selected for industrialized production so as to achieve the marketization of medicinal pteridophytes resources development.
