Three new flavonoid glycosides, named 7,8,4'-trihydroxy-3,5-dimethoxy-6-methylflavonol-8-O-β-D-glucopyranoside (1), 5,7,4'-trihydroxy-3-methoxy-6-methylflavonol-7-O-β-D-glucopyranoside (2), 3,5,7,4'-tetrahydroxy-6-methylflavonol-7-O-β-D-glucopyranoside (3), together with two known flavonoid glycosides were isolated from the needles of Pinus tabulaeformis Carr. Their structures were established on the basis of various spectroscopic analyses.
