为了研究野牡丹科药用植物地菍(Melastoma dodecandrum)的化学成分,采用柱层析方法分离鉴定了15个化合物,通过波谱分析及对比文献等方法鉴定为4-O-β-D-吡喃葡萄糖基-3,3’,4’-三甲氧基鞣花酸(1),槲皮素3-O-刺槐二糖苷(2),8-C-吡喃葡萄糖基-5,7,3’,4’-四羟基黄酮(3),3-O-β-D-吡喃葡萄糖基-4’,5,7-三羟基黄酮(4),6-C-吡喃葡萄糖基-4’,5,7-三羟基黄酮(5),3-hydroxy-22(29)-hopen-23-oic acid(6),2,3-dihydroxy-9(11)-fernen-23-oic acid(7),3β-sitosterol laminaribioside(8),姜糖酯B(9),3-O-β-D-galactopyranoside-glycerol1-alkanoates(10),胡萝卜苷(11),β-谷甾醇(12),二十八烷醇(13),二十四烷酸(14)以及三十四烷(15)化合物结构。所有化合物均为首次从该植物中分离得到。
In order to study the chemical constituents of Melastoma dodecandrum, fifteen compounds were isolated and identified by column chromatography and identified as 4-O-β-D-pyran by spectroscopic analysis and comparative literature 3 ’, 4’-trimethoxylatelane (1), quercetin 3-O-acacia bisglycoside (2), 8-C-glucopyranosyl-5,7,3’ (3), 3-O-β-D-glucopyranosyl-4 ’, 5,7-trihydroxyflavone (4), 6-C-glucopyranosyl- 3-hydroxy-22 (29) -hopen-23-oic acid (6), 2,3- dihydroxy-9 (11) 3β-sitosterol laminaribioside (8), Ginger ester B (9), 3-O-β-D-galactopyranoside-glycerol1-alkanoates Octadecanol (13), lignoceric acid (14) and tetradecane (15) compounds. All compounds were isolated from this plant for the first time.
