摘要：

Sumaresinolic acid [1] and 3-epi-sumaresinolic acid [2], a new natural product, have been isolated from Miconia stenostachya (Melastomataceae). The C-13 and H-1 chemical shifts of these compounds and a number of their derivatives have been assigned from 2D nmr spectra in which the FLOCK pulse sequence was used to establish 2- and 3-bond H-1-C-13 connectivities.
