[Comparison of flavonoids in medicinal plants Melastoma].

The flavonoids in Melastoma dodecandrum Lour., M. sanguineum Sims, M. normale D. Don, M. affine D. Don and M. candidum D. Don were compared by Thin Layer Chromatography (TLC). Rutin was detected in all samples, but flavonoids were similar in M. affine and M. candidum. It suggests that both M. affine and M. candidum can be used for the Herba Melastoma.
