共鉴定出19个化合物,包括17个生物碱O-甲基罂粟碱(1)、(S)-6-甲氧基-1-(4-甲氧基苄基)-2-甲基-1,2,3,4-四氢异喹啉-7-醇(2),(+)-(IR,1aR)-lahydroxymagnocurarin(3),(6R,6aS,P)-(+)-紫堇定(4)、(+)-N-甲基月桂破伤风碱(5)、木兰花碱(6)、3-羟基-1,2-二甲氧基-5-甲基-5H-二苯并吲哚-4-酮(7)、胡椒碱(8)、山楂碱B(9)、(S)-1-(3-甲氧基苯基)-N-甲基丙-2-胺(10),(乙酰氨基)苯甲酸酯(11)、2-羧基对氨基苯甲酸甲酯(12)、4-[2-(4-氨基苯基)-2-甲基-N-(2-甲基苯基)-2-氧代-N-甲基-N-(2-甲氧基苯基)-2-氧代-N-(2-甲氧基苯基)苯甲酸甲酯(12)、(甲氧羰基)苯胺基]-4-氧代丁酸甲酯(13),N-甲基紫堇定(14),N-甲基-6,7-二甲氧基异喹诺酮(15),(5S,6R,7S,8R)-5-amino-(2Z,4Z)-1,2,3-trihbuta-2,4-dienyloxy pentane-6,7,8,9-tetraol(16),nicotinic acid(17),以及两个megastigmane型化合物S(+)-dehydrovomifoliol(18)和megastigmane(19)。毛叶化合物1 - 3和5 - 19为首次从该植物中分离得到,其中化合物11为首次从天然植物中分离得到。细胞毒性评价显示化合物5对Hela细胞系显示出轻微的细胞毒性(IC 50 13.69 +/-0.036 μ M)。抗菌活性评价结果表明,化合物1和6对革兰氏阳性菌S.金黄色。
Nineteen compounds, including seventeen alkaloids O-methylarmepavine (1), (S)-6-methoxy-1-(4-methoxybenzyl)-2-methyl -1,2,3,4-tetrahydroisoquinolin-7-ol (2), (+)-(IR,laR)-lahydroxymagnocurarin (3), (6R,6aS,P)-(+)-corydine (4), (+)-N-methyllaurotetanine (5), magnoflorine (6), 3-hydroxy-1,2-dimethoxy-5-methyl-5H-dibenzoindol-4-one (7), imperialine (8), crispine B (9), (S)-1-(3-methoxyphenyl)-N-methylpropan-2-amine (10), methyl 2- (acetamino)benzoate (11), 2-carboxyoxanilic acid methylester (12), 4-[2-(methoxycarbonyl) anilino]-4-oxobutanoic acid methyl ester (13), N-methylcorydaldine (14), N-methyl-6,7- dimethoxyisoquinolone (15), (5S,6R,7S,8R)-5-amino-(2Z,4Z)-1,2,3-trihybuta-2,4-dienyloxypentane- 6,7,8,9-tetraol (16), nicotinic acid (17), and two megastigmane type compounds, S(+)- dehydrovomifoliol (18) and megastigmane (19), were isolated from the Aconitum barbatum var. puberulum Ledeb. Compounds 1-3 and 5-19 were isolated from this plant for the first time, of which compound 11 was isolated from natural source for the first time. Cytotoxicity evaluation revealed that compound 5 displayed mild cytotoxicity against the Hela cell lines (IC50 13.69 +/- 0.036 mu M). Antibacterial activity evaluation revealed that compounds 1 and 6 showed strong antibacterial activity against the Gram-positive bacterium, S. aureus.
