该文对合欢Albizzia julibrissin干燥花序的乙酸乙酯萃取部位进行化学成分研究,采用硅胶,Sephadex LH-20,MCI GEL CHP-20P等柱色谱技术分离纯化,利用波谱数据(1H,13C-NMR,MS)进行结构鉴定,共分离和鉴定29个化合物,分别为8-hydroxy-2,6-dimethyl-2E,6Z-octadienoic acid(1),8-O-formyl-2,6-dimethyl-2E,6Z-octadienoic acid(1a),8-hydroxy-2,6-dimethyl-2E,6E-octadienoic acid(2),8-O-formyl-2,6-dimethyl-2E,6E-octadienoic acid(2a),(2E,6S)-2,6-二甲基-6-O-β-D-吡喃木糖基-2,7-辛二烯酸(3),clovan-2β,9α-diol(4),2β-O-formyl-clovan-9α-ol(4a),2β,9α-O-diformyl-clovan(4b),吐叶醇(5),(6S,9R)-roseoside(6),香草醛(7),4-O-乙基没食子酸(8),3-乙氧基-4-羟基苯甲酸(9),对-羟基苯甲醛(10),没食子酸(11),原儿茶酸(12),硬脂酸(13),软脂酸(14),2,3-dihydroxypropyl hexadecanoate(15),亚油酸(16),东莨菪内酯(17),3-吲哚甲醛(18),2-呋喃甲酸(19),5-羟甲基糠醛(20),(22E,24R)-5α,8α-epidioxy-ergosta-6,22-dien-3β-ol(21),(22E,24R)-5α,8α-epidioxy-ergosta-6,9,22-trien-3β-ol(22),(+)-lariciresinol 9’-stearate(23),芒柄花素(24)和尿苷(25)。其中,化合物1a,2a,4a,4b为分离过程中产生新的人工产物,其他25个化合物均为首次从该植物中分离得到。
In this paper, the chemical constituents of the ethyl acetate extract of Albizzia julibrissin dry flower were studied. The constituents were isolated and purified by column chromatography on silica gel, Sephadex LH-20 and MCI GEL CHP-20P. The spectral data (1H, 13C-NMR, MS ) For structural identification. A total of 29 compounds were isolated and identified as 8-hydroxy-2,6-dimethyl-2E, 6Z-octadienoic acid octadienoic acid (2a), 8-hydroxy-2,6-dimethyl-2E, 6E- octadienoic acid (2), 8-O-formyl- 2E, 6S) -2,6-dimethyl-6-O-β-D-xylopyranosyl-2,7-octadienoate (3) 2β-O-formyl-clovan-9α-ol (4a), 2β, 9α-O-diformyl- clovan (4b), vincloin (5), (6S, 9R) -roseoside (8), 3-ethoxy-4-hydroxybenzoic acid (9), p-hydroxybenzaldehyde (10), gallic acid (11), protocatechuic acid ) Stearic acid (13) palmitate (14) 2,3-dihydroxypropyl hexadecanoate (15) linoleic acid (16) scopolactone (17) 2-furoic acid (19), 5-hydroxymethylfurfural (20), (22E, 24R) -5α, 8α-epidioxy- ergosta-6,22-dien- 2E, 24R) -5α, 8α-epidioxy-ergosta-6,9,22-trien-3β-ol (+) - lariciresinol 9’- stearate (23) Glycoside (25). Among them, compounds 1a, 2a, 4a, 4b produced new artificial products during the separation process, and the other 25 compounds were isolated from this plant for the first time.
