摘  要:从马尾松(Pinusmassoniana)枝条中分离得到21个已知化合物,经波谱学方法将其结构鉴定为7,13,15-abietatrien-18-oic acid(1),12-methoxy-7,13-abietadien-18-oica cid(2),15-methoxy-7,13-abietadien-18-oic acid methyl ester(3),12-hydroxydehydroabietic acid(4),dehydroabietic acid(5),15-hydroxydehydroabi-etic acid methyl ester(6),3β-methoxyserrat-14-en-21-one(7),3β-methoxy-30-hydroxyserrat-14-en-21-one(8),β-sitosterol(9),(±)-pinoresinol(10),(±)-matairesinol(11),(-)-nortrachelogenin(12),balanophonin(13),cedrusin(14),pinocembin(15),5-methoxypinosylvin(16),pinosylvin(17),1,2-bis-(4-hydroxy-3-methoxyphenyl)-propane-1,3-diol(18),cleistophostaudin(19),lignoceryl ferulate(20)和coniferaldehyde(21)。其中化合物12,14,18和21在DPPH抗氧化模型上显示一定的抗氧化活性,其EC50值分别为11.36,6.76,14.07和13.33μg·mL-1。化合物2~4,6~8,10,11,13,15~21均是从该植物中首次分离得到。Twenty one known compounds were isolated from the twigs of Pinus massoniana. Their structures were elucidated as 7, 13, 15-abietatrien-18-oic acid (1), 12-methoxy-7, 13-abietadien-18-oic acid (2), 15-methoxy-7, 13-abietadien-18-oic acid methyl ester (3), 12-hydroxydehydroabietic acid (4), dehydroabietic acid (5), 15- hydroxydehydroabietic acid methyl ester ( 6 ), 3B-methoxyserrat-14-en-21-one ( 7 ), 3^-methoxy-30-hydroxyserrat- 14-en-21-one (8), fl-sitosteml ( 9 ), ( ~ ) -pinoresinol ( 10 ), ( ~ )-matairesinol ( 11 ), ( - )-nortrachelogenin ( 12 ), balanophonin ( 13 ), eedrusin ( 14 ), pinoeembin ( 15 ), 5-methoxypinosylvin ( 16 ), pinosylvin ( 17 ), 1,2- bis-(4-hydroxy-3-methoxyphenyl) -propane-l, 3-diol ( 18 ), cleistophostaudin ( 19 ), lignoeeryl ferulate ( 20 ) and coniferaldehyde (21). Compounds 12, 14, 18 and 21 showed antioxidant aetivities on DPPH assay with ECs0 values of 11.36, 6.76, 14.07, and 13.33μg- mL-1 , respectively. Compounds 2-4, 6-8, 10, 11, 13 and 15-21 were isolated from this plant for the first time.
