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.
从 Pinus densiflora（松科）针的甲醇提取物的乙酸乙酯部分，分离得到了一个新的二萜糖苷[9alpha,13alpha-环氧-8beta,14beta-二羟基-松香酸-18-O-beta-D: -吡喃葡萄糖苷]（1），两个黄酮糖苷[山柰酚 3-O-beta-D: -吡喃葡萄糖苷（2）和 6-C-甲基山柰酚 3-O-beta-D: -吡喃葡萄糖苷（3）]，和两个单萜糖苷[莰烯 6-O-alpha-L-阿拉伯呋喃糖基（1-->6）-beta-D: -吡喃葡萄糖苷（4）和莰烯 6-O-beta-D: -阿魏酰基（1-->6）-beta-D: -吡喃葡萄糖苷（5）]。基于光谱分析对所有化合物进行了分离和表征。所有化合物中，2 和 3 表现出对过氧亚硝基阴离子的清除活性。
