为了解黄花三宝木(Trigonostemon lutescens Y.T.Chang et J.Y.Liang)的化学成分,采用硅胶柱色谱与Sephadex LH-20凝胶柱色谱从黄花三宝木乙醇提取物的石油醚与正丁醇萃取部分共分离11个化合物,其结构分别鉴定为:ent-kaurane-3β,16β-diol(1)、(3R,6R,7E)-3-hydroxy-4,7-megastigmadien-9-one(2)、palmarumycin JC2(3)、(±)-3-(3,4,5-trimethoxyphenyl)-1,2-propanediol(4)、赤式-愈创木基甘油-β-O-4′-松柏基醚(5)、苏式-愈创木基甘油-β-O-4′-松柏基醚(6)、3-hydroxymethyl-5-(3-hydroxypropyl)-7-methoxy-2-{3-methoxy-4-[1-(3,4-dimethoxybenzyl)-2-hydroxyethyl]phenyl}-2,3-dihydrobenzofuran(7)、ancistrocline(8)、hamatine(9)、东莨菪苷(10)和紫丁香苷(11)。上述化合物均为首次从该种植物中分离得到,其中化合物1、3~11为首次从该属植物中分离得到。
To understand the chemical constituents of Trigonostemon lutescens YTChang et JYLiang, silica gel column and Sephadex LH-20 gel column chromatography were used to separate petroleum ether and n-butanol extracts The structures of the compounds were identified as: ent-kaurane-3β, 16β-diol (1R), 3R, 6R, 7E) -3-hydroxy-4,7-megastigmadien-9- one (2), palmarumycin JC2 (4), erythro-guaifenesin-β-O-4’-cypionylether (5), (±) -3- (3,4,5-trimethoxyphenyl) -1,2-propanediol , The threo-guaifenesin-beta-O-4’-cypionylether (6), 3-hydroxymethyl- 5- 1- (3,4-dimethoxybenzyl) -2-hydroxyethyl] phenyl} -2,3-dihydrobenzofuran (7), ancistrocline (8), hamatine (9), scopolin (10) and syringin (11). The above compounds were isolated from this species for the first time, of which compounds 1, 3 ~ 11 were isolated from this genus for the first time.
