To investigate the chemical constituents of the branches and leaves of Polyalthia nemoralis.
The compounds were isolated and purified by silica gel, macroporous adsorption resin and Sephadex LH-20 column chromatographic methods. Their chemical structures were elucidated on the basis of physicochemical properties and spectral data.
Fourteen compounds were isolated and identified as syringic acid (1), 3-methoxy-4-hydroxycinnamic acid (2), vanillic acid (3), 4-hydroxybenzoic acid (4), mauritianin (5), (+)-xylopinidine (6), (+)-oblongine(7), (+)-tembetarine (8), eythritol (9), D-mannitol (10), ethyl-beta-D-glucopyranoside (11), (+)-magnoflorine (12), stepharanine (13), (2S, 4R)-4-hydroxy-2-piperidine-carboxylic acid (14), respectively.
All the compounds were isolated from the genus Polyalthia for the first time; compounds 6 and 13 showed inhibitation activities against multi tumor cell lines.
研究毛叶暗罗枝叶的化学成分。
采用硅胶柱色谱、大孔吸附树脂柱色谱及Sephadex LH - 20柱色谱法对化合物进行分离纯化，并根据其理化性质和光谱数据确定化学结构。
分离鉴定出14个化合物，分别为丁香酸（1）、3 - 甲氧基 - 4 - 羟基肉桂酸（2）、香草酸（3）、4 - 羟基苯甲酸（4）、毛叶暗罗宁（5）、（+）- 木番荔枝定（6）、（+）- 暗罗碱（7）、（+）- 粉蕊黄杨碱（8）、赤藓醇（9）、D - 甘露醇（10）、β - D - 葡萄糖吡喃苷乙酯（11）、（+）- 木兰花碱（12）、千金藤宁碱（13）、（2S，4R）- 4 - 羟基 - 2 - 哌啶羧酸（14）。
所有化合物均为首次从暗罗属植物中分离得到；化合物6和13对多种肿瘤细胞系具有抑制活性。
