Abstract
From the ethyl acetate fraction of the methanol extract of the needles of Pinus densiflora (Pinaceae), a new diterpenoid glucoside [9alpha,13alpha-epoxy-8beta,14beta-dihydroxy-abietic acid-18-O-beta-D: -glucopyranoside] (1), two flavonoid glucosides [kaempferol 3-O-beta-D: -glucoside (2) and 6-C-methyl kaempferol 3-O-beta-D: -glucoside (3)], and two monoterpenoid glucosides [bornyl 6-O-alpha-Larabinofuranosyl (1-->6)-beta-D: -glucopyranoside (4) and bornyl 6-O-beta-D: -apiofuranosyl (1-->6)-beta-D: -glucopyranoside (5)] were isolated and characterized on the basis of spectral analysis. Of all the compounds, 2 and 3 showed peroxynitrite scavenging activity.
