| 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 uncinate. 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.
