【摘要】 目的对滇白珠Gaultheria leucocarpa var.yunnanensis抗炎镇痛活性部位(ARF)的化学成分进行研究。方法利用MCI-Gel CHP、AB-8大孔吸附树脂、薄层色谱等方法进行分离和纯化,根据理化性质和波谱数据进行结构鉴定。结果从滇白珠30%乙醇提取物即ARF中分离得到16个化合物,其中水杨酸甲酯糖苷类化合物4个:水杨酸甲酯-2-O-β-D-吡喃葡萄糖苷(1)、冬绿苷(2)、水杨酸甲酯-2-O-β-D-吡喃木糖基(1→2)[O-β-D-吡喃木糖基(1→6)]-O-β-D-吡喃葡萄糖苷(3)、水杨酸甲酯-2-O-β-D-吡喃葡萄糖基(1→2)[O-β-D-吡喃木糖基(1→6)]-O-β-D-吡喃葡萄糖苷(4);醇苷类化合物3个:乙基-O-β-D-吡喃木糖苷(5)、乙基-O-β-D-吡喃木糖基(1→6)-O-β-D-吡喃葡萄糖苷(6)、甲基-O-β-D-吡喃木糖基(1→6)-O-β-D-吡喃葡萄糖苷(7);单萜苷类化合物2个:长寿花糖苷(8)、芍药苷(9);苯甲酸类化合物5个:香草酸(10)、2,5-二羟基苯甲酸(11)、3,4-二甲氧基肉桂酸(12)、阿魏酸(13)、绿原酸(14);其他成分2个:4-羟基-2,6-二甲氧基苯基-O-β-D-葡萄糖苷(15)和3-甲氧基-1H-吡咯(16)。结论化合物5~9、12、15、16是首次从该植物中分离得到,其中化合物7为首次从白珠树属植物中分离得到,化合物8、9、12、15是首次从杜鹃花科植物中分离得到。更多还原

【Abstract】 Objective To study the chemical constituents from anti-inflammatory and analgesic active fraction(ARF) of Gaultherialeucocarpa var. yunnanensis. Methods The compounds were isolated and purified by various techniques of column chromatography, and their structures were determined according to physicochemical properties and spectral analyses. Results Sixteen compounds were obtained and identified as methyl salicylate 2-O-β-D-glucopyranoside(1), gaultherin(2), MSTG-A(3), MSTG-B(4), ethyl-O-β-D-xylopyranoside(5), ethyl-O-β-D-xylopyranosyl(1→6)-O-β-D-glucopyranoside(6), methyl-O-β-D-xylopyranosyl(1→6)-O-β-D-glucopyranoside(7), roseoside(8), paeoniflorin(9), vanillic acid(10), 2,5-dihydroxybenzoic acid(11), 3,4-dimethoxycinnamic acid(12), ferulic acid(13), chlorogenic acid(14), 4-hydroxy-2,6-dimethoxyphenol-O-β-D-glucopyranoside(15), and 3-methoxyl-1H-pyrrole(16). Conclusion Compounds 5—9, 12, 15, and 16 are obtained from this plant and compound 7 is isolated from the plants of genus Gaultheria Kalm ex L. for the first time. Compounds 8, 9, 12, and 15 are obtained from family Ericaceae for the first time.更多还原
