Abstract: Ten phenolic compounds were isolated from the fresh leaves of Myrica nana Cheval. They were identified as myricetin ,myricetin 3-O-α-L-arabino-pyranoside,myricitrin 3-O-β-D-ranoside,myricitrin（myricetin 3-O-α-L-rhamnopyranoside）,kaempferol 3-O-β-D-gucopyranoside、(-)epigallocatechin 3-O-gallate,(-)epicatechin 3-O-gallate,prodelphinidin B-2,prodelphinidin B-2 3′-O-gallate and gallic acid,respectively,by means of spectral methods.
