Abstract

Abstract: Correlation between medicinal material properties and diversity of wild medicinal plant resources in Dehang scenic spot was analyzed.The species composition,the life forms,the geographical distribution and the medicinal parts were statistically analyzed by field investigation,specimen arrangement and literature review.On this basis,association rule method was used to analyze the correlation between medicinal plant family and genus,medicinal chemical composition and medicinal efficacy.The results show that there are 617 species of wild medicinal plants belonging to 406 genera and 137 families in Dehang scenic spot.The life forms are mainly herb.As for the floristic geographical distribution at the family level,the medicinal plant flora is mainly global and pan-tropical;at the genus level,the medicinal plant flora is mainly north temperate and pan-tropical;and at the species level,the medicinal plant flora is mainly East Asia.The medicinal parts are mainly the whole plant,roots and rhizomes.A total of 36 strong association rules were screened by association rule analysis,among which liliaceae-saponins,zanthoxylum-alkaloids are highly correlated in terms of chemical components,and Liliaceae-expectorant cough suppressant and anti-asthmatic drug,and Hypericum-styptic are highly correlated in terms of medicinal efficacy.The results show that species of the medicinal plants are rich in Dehang scenic spot and their life forms are diverse.The floristic geographical composition is complex.According to the correlation between medicinal plant family,chemical composition and efficacy,it can be concluded that new drugs with better efficacy and less toxicity can be found in nature.

Key words: plant resources, medicinal plant, resources investigation, association, Dehang
