Two New Chromone Glycosides from Selaginella uncinata
摘要:
Two new chromone glycosides, 5-hydroxy-2,6,8-trimethylchromon-7-O-β-D-gluco-pyranoside, named uncinoside A; 5-acetoxy-2,6,8-trimethylchromone-7-O-β-D-glucopyranoside, named uncinoside B, and a known chromone compound named 8-methyl eugenitol were isolated from Selaginella uncinata. Their structures were elucidated by spectra analysis of FAB-MS, 1D NMR and 2D NMR including 1H NMR, 13C NMR, HMQC, HMBC and single-crystal X-ray diffraction techniques.
