Abstract

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