Two new megastigmane sulphonoglucosides from Mallotus anisopodus.
Phytochemical study of the methanol extract of Mallotus anisopodus led to the isolation of two new megastigmane sulphonoglucosides, namely anisoposides A (1) and B (2), along with junipetrioloside A (3), bergenin (4), os-tocopherol, and N1-methyl-2-pyridone-5-carboxamide. Their structures were deduced by spectroscopic and spectrometric methods including 1D-, 2D-NMR, ESI-MS, and HRESI-MS.
