摘要:
Two new phenolic glycosides, named parishins F-G (1-2), together with known parishin E, were isolated from the rhizome of Gastrodia elata. The new structures were established as 1,3-di-[4-O-(beta-D-glucopyranosyl) benzyl]-2-{4-O-[beta-D-glucopyranosyl-(1 -> 6)-beta-D-glucopyranosyl] benzyl} citrate (1) and 2-[4-O-(beta-D-glucopyranosyl) benzyl] citrate (2), by means of MS, 1D, and 2D NMR spectral analyses, as well as chemical methods.
