从八角枫叶中分离出二个新的酚糖甙6’-O-β-D-吡喃木糖水杨甙(1)和6’-O-反式-咖啡酰水杨甙(2),并用光谱法确定了结构。 取干燥的八角枫叶179.3g,用6L甲醇热提取。将甲醇提取物在真空中浓缩,残渣56.4g溶于1.5L水中,用3L氯仿和7.5L正丁醇依次萃取。正丁醇层浓缩得残渣17.4g,以氯仿-甲醇为流动相进行硅胶柱层析,可得 Two new phenolic glycosides 6’-O-β-D-xylo-xyloside (1) and 6’-O-trans-caffeoyl salicylate (2) were isolated from the octagonal maple leaves and used Spectroscopy determines the structure. A dried octagonal maple leaf 179.3 g was taken and extracted with 6 L of methanol. The methanol extract was concentrated in vacuo and 56.4 g of the residue was dissolved in 1.5 L of water and extracted sequentially with 3 L of chloroform and 7.5 L of n-butanol. The n-butanol layer was concentrated to a residue of 17.4 g. Chloroform-methanol was used as the mobile phase for silica gel column chromatography.
