Chemical constituents from roots of Distylium myricoides

OBJECTIVE To study the chemical constituents from the roots of Distylium myricoides. METHOD The chemical constituents were isolated and separated with chromatographic techniques, and structures were identified by spectroscopic methods. RESULT Eight phenolic compounds were isolated and identified as: 4-hydroxy-2-methoxyphenol 1-O-beta-D-(6'-O-galloyl) glucopyranoside (1), 4-hydroxy-3-methoxy-phenol 1-O-beta-D-(6'-O-galloyl) glucopyranoside (2), 3,4,5-tri methoxyphenol 1-O-beta-D-(6'-O-galloyl) glucopyranoside (3), 1,2,3,4,6-penta-O-galloyl-beta-D-glucopyranoside (4), methyl gallate (5), ethyl gallate (6), 3,4-dihydroxybenzoic acid (7), gallic acid (8). CONCLUSION All compounds were isolated from the genus Distylium for the first time.
