Abstract: In order to select Anoectochilus roxburghii varieties to plant tissue culture,this experiment analyzed 13 different varieties(lines)view apparent character and functional components contents of Anoectochilus roxburghii .And it shows that different varieties of Anoectochilus roxburghii with high water content from 85.07% to 90.91%.however,it is poor in records of the level；The content of alcohol soluble extractive is 13.62%-41.71%,the content of total flavonoids is 815-40.72 mg/g,the polysaccharide content in the range of 2.10%-25.61%.It shows that the alcohol soluble extractive content positively correlated with total flavonoids of roxburghii,moisture content and polysaccharide content is negatively correlated with them;there are three kinds of Anoectochilus roxburghii  which possesses higher comprehensive score.There are  Anoectochilus formosanus,large circular leaf Anoectochilus Yunnanensis,Large leaf Anoectochilus Fujianensis.In Chenzhou Anoectochilus Hunanensis,gathered a lot of nutrients,soluble extract content alcohol is 41.71%,the content of total flavonoids is 40.72 mg/g,significantly higher than other varieties;And 5 varieties(lines)of Anoectochilus roxburghii from Fujian’s alcohol soluble extract and total flavonoids content being the lowest,the content of polysaccharide.So choosing promote Anoectochilus formosanus,Large leaf Anoectochilus Yunnanensis,Large leaf Anoectochilus Fujianensis and Anoectochilus Chenzhou Hunanensis can be more conducive to the accumulation of effective components and ornamental material.
