Abstract: According to assaying the soluble sugar, soluble protein and flavonoids of 18 leaves of Litsea Coreana clones, the correlation analysis of Litsea Coreana clones by use of variance analysis has shown that varied samples have significant differences in the content of soluble sugar, soluble protein and flavonoids(P < 0.05). The clustering analysis has also shown that the Litsea Coreana can be divided into three categories on the basis of the component content of inclusions and among them No.38 sample exhibits the best comprehensiveness.
