【摘要】 采用正相硅胶、RP-18、MCI、Sephadex LH-20柱色谱和中压液相色谱等方法对云南松松塔乙醇提取物的化学成分进行分离纯化,运用现代波谱技术鉴定了13个化合物,分别为:16-降-15-氧代脱氢松香酸(1)、16-降-7,15-二氧代脱氢松香酸(2)、7α,15-二羟基脱氢松香酸(3)、15-羟基-7-氧代脱氢松香酸甲酯(4)、南洋杉酸(5)、异考布松(6)、交链孢酚(7)、罗汉松脂素(8)、(+)-表松脂素(9)、二氢槲皮素3’-O-葡萄糖甙(10)、赤松素(11)、(Z)-3-羟基-5-甲氧基二苯乙烯(12)、松柏醛(13)。所有化合物均为首次从云南松中分离得到,化合物1、2、6、7、9为首次从松属中分离得到。更多还原

【Abstract】 Thirteen compounds were isolated and purified from the ethanolic extracts of pine cone of Pinus yunnanensis by MPLC and column chromatography on silica gel,RP-18,MCI,and Sephadex LH-20. On the basis of spectroscopic analysis,the isolated compounds were identified as 16-nor-15-oxodehydroabietic acid(1),16-nor-7,15-dioxodehydroabietic acid(2),7α,15-dihydroxydehydroabietic acid(3),methyl 15-hydroxy-7-oxodehydroabietate(4),imbricatolic acid(5),isokobusone(6),alternariol(7),matairesinol(8),(+)-epipinoresinol(9),taxifolin 3’-O-glucoside(10),pinosylvin(11),(Z)-3-hydroxy-5-methoxystilbene(12) and coniferaldehyde(13). All compounds were obtained from P.yunnanensis for the first time and compounds 1,2,6,7 and 9 were obtained from the genus Pinus for the first time.更多还原
