目的对马尾松Pinus massoniana鲜松叶的化学成分进行研究。方法运用硅胶、Sephadex LH-20、ODS、SBC MCI等柱色谱进行分离纯化,根据理化性质和波谱数据鉴定化合物的结构。结果从马尾松鲜松叶中分离得到14个化合物,分别鉴定为(+)-儿茶素(1)、(+)-没食子儿茶素(2)、3,5-二羟基苯基-1-O-β-D-吡喃葡萄糖苷(3)、tachioside(4)、3,4-二甲氧基苯基-1-O-β-D-吡喃葡萄糖苷(5)、3,4-二甲氧基苯基-1-O-(3-O-甲氧基-α-L-鼠李糖基)-1→2-β-D-吡喃葡萄糖苷(6)、citrusin D(7)、(6S,7E,9R)-长寿花糖苷(8)、4-(2-丁酮)-苯基-1-O-β-D-吡喃葡萄糖苷(9)、(-)-10-α-O-β-D-葡萄糖基-刺参-4-酮(10)、massonianoside D(11)、massonianoside B(12)、异落叶松脂醇-9′-O-α-L-阿拉伯糖苷(13)、(2R,3R)-花旗松素-3′-O-β-D-吡喃葡萄糖苷(14)。结论化合物2~6、10为首次从该属植物中分离得到,7~9为首次从该植物中分离得到。
Aim To study the chemical constituents of Pinus massoniana fresh leaves. Methods The compounds were isolated and purified by column chromatography on silica gel, Sephadex LH-20, ODS and SBC MCI. The structures of the compounds were identified by their physico-chemical properties and spectral data. Results Fourteen compounds were isolated from fresh pine needles of Pinus massoniana and identified as (+) - catechin (1), (+) - gallocatechin (2), 3,5-dihydroxyphenyl- O-β-D-glucopyranoside (3), tachioside (4), 3,4-dimethoxyphenyl-1-O- -Dimethoxyphenyl-1-O- (3-O-methoxy-α-L-rhamnosyl) -1 → 2-β-D-glucopyranoside (6), citrusin D (9), (-) - 4-butanone, (6S, 7E, 9R) 10-α-O-β-D-glucosyl-Stemon-4-one (10), massonianoside D (11), massonianoside B Glycosides (13), (2R, 3R) -digitin-3’-O-β-D-glucopyranoside (14). Conclusion Compounds 2 ~ 6 and 10 were isolated from this genus for the first time, and 7 ~ 9 were isolated from this plant for the first time.
