摘要:为了分析德夯风景名胜区药用植物资源的多样性特征及药材属性关联性,采用野外调查、标本整理、文献查阅等方法,对该地区药用植物资源的物种构成、生活型、地理成分、药用部位等进行统计分析.在此基础上,采用关联规则方法分析药用植物科属、药用化学成分与药用功效之间的关联性.结果表明:德夯风景名胜区野生药用植物共137科406属617种,生活型以草本为主;药用植物区系地理成分在科层面以世界分布和泛热带分布为主,属层面以北温带分布和泛热带分布为主,种层面以东亚分布为主;药用部位以全草类、根及根茎类为主.关联规则方法共筛选出强关联规则36条,其中药用植物科属与化学成分关联性较高的有百合科-皂苷类和花椒属-生物碱类等;药用植物科属与药用功效关联性较高的有百合科-化痰止咳平喘药和金丝桃属-止血药等.德夯风景名胜区药用植物种类较为丰富,生活型多样,区系地理成分复杂.药用植物科属、药用化学成分与药用功效之间的内在关联性,可为寻找自然界中药用功效更好、毒性更低的新药物提供参考.

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.
