摘要
目的:对伊桐(Itoa orientalis)叶的化学成分进行研究。方法:采用硅胶,Sephadex LH-20,ODS柱层析分离化合物;通过MS,1DNMR和2DNMR数据鉴定结构。结果:分离鉴定了5个化合物,分别为2,3-双-顺式亚麻酸甘油酯-1-O-β-D-半乳糖苷(1),2,3-双棕榈酸甘油酯-1-(β-D-半乳糖-(6-1)-O-α-D-半乳糖苷(2),2-顺式亚麻酸,3-顺式亚油酸甘油酯-1-O-β-D-半乳糖(6-1)-α-D-半乳糖苷(3),3-羟基,2-顺式亚麻酸甘油酯-1-(β-D-半乳糖-(6-1)-O-α-D-半乳糖苷(4)和(3S,5R,6R,7E,9S)-megastigman-7-ene-3,5,6,9-tetrol3-O-β-D-glucopyr-anoside(5)。所有化合物均为首次从本属植物中分离得到,其中化合物1为首次报道其NMR数据。
AIM: To investigate the chemical constituents from the leaves of Itoa orientalis Hemsl.. METHODS: Chromatography of silica gel, Sephadex LH-20 and ODS and spectral analysis of MS, 1D and 2D NMR were respectively used to isolate and identify the constituents. RESULTS: Five compounds were isolated from the leaves of Itoa orientalis Hemsl.. and identified as β- D-galactopyranoside, 2, 3-bis[ ( 1-oxo-9, 12, 15-octadecatrienyl) oxy] propyl(1),β-D-galactopyranoside, 2, 3-bis[ ( 1-oxo-hexadecyl) oxy] propyl-6-O-α-D-galactopyranyl(2),β-D-galactopyranoside, (2S) -3-[ [ ( 9Z, 12Z) -1-oxo-9, 12-octadecadienyl] oxy] -2-[ [ ( 9Z, 12Z, 15Z)-1-oxo-9, 12, 15-octadecatrienyl] oxy] propyl-6-O-α-D-galactopyranosyl(3), gingerglycolipid A(4) and( 3S, 5R, 6R, 7E, 9S) -megastigman-7-ene-3, 5, 6, 9-tetrol 3-O-β-D-glucopyranoside(5). CONCLUSION: All compounds were isolated from the genus for the first time, among which the NMR data of compound 1 was firstly reported.
