【摘要】 【目的】为进一步开发光叶子花的药用价值,对光叶子花进行了化学成分研究。【方法】通过硅胶、Sephadex LH-20凝胶及RP-C18反相硅胶等色谱柱分离纯化,并运用MS和NMR等波谱学方法鉴定化合物的化学结构。【结果】从光叶子花花的工业甲醇提取物中分离得到6个化合物,分别鉴定为:D-松醇(1)、菠甾醇(2)、3-O-[6′-O-palmitoyl-β-D-glucosyl]-spinasta-7,22-diene (3)、胡萝卜苷(4)、isorhamnetin-3-O-(6′′-O-E-feruloyl)-β-D-galactopyranoside (5)、isorhamnetin-3-O-β-D-glucopyranoside (6)。【结论】光叶子花的化学成分研究较少,本文较深入地对其花的化学成分进行了研究,化合物2、5和6均为首次从该植物中分离得到,在一定程度上丰富了光叶子花的化学成分研究,有利于进一步开发其药用价值。更多还原

【Abstract】 [Purpose]The study on the chemical constituents of the flower of Bougainvillea glabra Choisy was to exploit its medicinal value.[Method]Compounds were isolated by column chromatography of silica gel, Sephadex LH-20 and RP-C18, and their structures were identified by spectral methods(MS and NMR).[Result]Six compounds were finally isolated and identified as D-pinitol(1), α-spinaterol(2), 3-O-[6′-O-palmitoyl-β-D-glucosyl]-spinasta-7,22-diene(3), daucosterol(4), isorhamnetin-3-O-(6 ′ ′-O-E-feruloyl)-β-D-galactopyranoside(5), and isorhamnetin-3-O-β-D-glucopyranoside(6), respectively.[Conclusion]There are few reports on the chemical constitents of B. glabra,and we extensively investigated the chemical constituents of its flower. Compounds 2, 5 and 6 were isolated from this species for the first time. To a certain extent, our study enriched the chemical constituents of B. glabra. This work will be conducive to the exploiting of the medicinal value of B. glabra.更多还原
