摘要：

Three new hydrolysable tannin dimers, malabathrins B, C and D, and 11 known tannins including three dimers (nobotanins B, G and H) and a trimer (nobotanin J), have been isolated from the leaves of Melastoma malabathricum. The structures of new dimers were determined by spectral analysis and chemical correlations with nobotanins B and J.
