摘要:

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。

Abstract:

Fifteen compounds were isolated from the ethanol extract of Melastoma dodecandrum. Their structures were elucidated as 4-O-β-D-glucopyranosyl-3,3',4'-tri-O-methylellagic acid (1), quercetin 3-robinobioside (2), 8-C-glucopyranosyl-5,7,3',4'-tetrahydroxyflavone (3), 3-O-β-D-glucopyranosyloxy-4',5,7-trihydroxy flavone (4), 6-C-galactopyranosyl-4',5,7-trihydroxyflavone (5), 3-hydroxy-22(29)-hopen-23-oic acid (6), 2,3-dihydroxy-9(11)-fernen-23-oic acid (7), 3β-sitosterol laminaribioside (8), gingerglycolipid B (9), 3-O-β-D-galactopyranoside-glycerol1-alkanoates (10), daucosterol (11), β-sitosterol (12), octacosanol (13), tetracosanoic acid (14), and tetratriacontane (15) on the basis of spectroscopic analysis and comparison of their spectral data with those of reported. All compounds were isolated from this plant for the first time.
