目的:对苦木科臭椿属植物臭椿Ailanthus altissima的果实,即凤眼草的提取物进行分离并鉴定。方法:经反复纯化制备化合物,并根据化合物的理化性质分析、波谱解析、对照品比较及与文献报道对比鉴定化合物的化学结构。结果:分离并鉴定12个化合物,分别为(+)-异落叶松树脂醇(1),异落叶松树脂醇9-O-β-D-吡喃葡萄糖苷(2),没食子酸(3),山梨醇(4),香草醛(5),七叶内酯(6),豆甾-4-烯-3-酮(7),5α,8α-过氧化麦角甾-6,9(11),22E-三烯-3β-醇(8),麦角甾-4,6,8(14),22E-四烯-3-酮(9),环桉烯醇(10),羽扇豆醇(11),桦木酸(12)。结论:化合物1~12均为从本属首次分离得到。
OBJECTIVE: To isolate and identify the fruit of Ailanthus altissima, an extract of Acacia crassipes, from the genus Ailanthus. Methods: The compounds were prepared by repeated purification. According to the physical and chemical properties of the compounds, spectral analysis, comparison of reference materials and the comparison with the literature, the chemical structures of the compounds were identified. Results: Twelve compounds were isolated and identified as (+) - luteolin resin (1), larch myristylol (2), gallic acid (3) , Sorbitol (4), vanillin (5), esculetin (6), stigmastan-4-en-3-one (7), 5a, 8a-ergosta-6,9 (11) (8), ergistetra-4,6,8 (14), 22E-tetraen-3-one (9), cycloallulenol (10), lupine ), Betulinic acid (12). Conclusion: Compounds 1 ~ 12 were isolated from this genus for the first time.
