AbstractObjectiveTo study the flavonoid constituents of the bark of Hunan Myrica ruba. MethodsThe chemical constituents were separated and repeatedly purified by methods of chromatography, and their structures were elucidated by UV, IR, MS and NMR. ResultsSix flavones were obtained and they were identified as Quercetin(1), Myricetin(2), Quercetin-3-O-β-D-glucoside(3), Quercetin-3-O-α-L-rhamnoside(4), Myricetrin(5) and Myricetin-3-O-β-D-glucoside (6). Conclusion1，4，6 were isolated from the bark of Hunan Myrica ruba for the first time. Myricetin is the main constituent of the bark of Hunan Myrica ruba, and this plant can be utilized as plant sources of myri……
