目的研究油松松针中的化学成分,为松属植物的化学分类学提供一定的依据。方法采用反复硅胶、聚酰胺、ODS、Sephadex LH-20柱色谱等方法进行分离纯化,根据理化性质和1H-NMR、13C-NMR等技术对分离得到的化合物进行结构鉴定。结果从油松松针中分离得到7个化合物,分别鉴定为(13S)-15-羟基半日花烷-8(17)-烯-19-酸[(13S)-15-hydroxylabd-8(17)-en-19-oicacid,1]、5,4′-二羟基-3,7,8-三甲氧基-6-甲基黄酮(5,4′-dihydroxy-3,7,8-trimethoxy-6-methylflavone,2)、柚皮素(naringenin,3)、芹菜素(apigenin,4)、高良姜素(galangin,5)、β-谷甾醇(β-sitosterol,6)、胡萝卜苷(paucosterol,7)。结论化合物1-3为首次从该属中分离得到,化合物4-7为首次从该植物中分离得到。
Aim To study the chemical constituents in pine needles of Pinus tabulaeformis and provide a basis for the chemical taxonomy of Pinus. Methods The compounds were separated and purified by repeated silica gel, polyamide, ODS and Sephadex LH-20 column chromatography. The structures of the isolated compounds were identified by 1H-NMR and 13C-NMR. Results Seven compounds were isolated from pine needles of Pinus tabulaeformis and identified as (13S) -15-hydroxylabd-8 (17) - en-19-oicacid, 1], 5,4’-dihydroxy-3,7,8-trimethoxy-6- methylflavone 2, naringenin 3, apigenin 4, galangin 5, β-sitosterol 6, paucosterol 7, . Conclusion Compounds 1-3 were isolated from this genus for the first time. Compounds 4-7 were isolated from this plant for the first time.
