OBJECTIVE
To study the chemical constituents from Rhodobryum roseum.
METHOD
The compounds were isolated and purified by recrystallization and chromatography with silica gel and sephadex LH-20 column. Their structures were identified by physicochemical properties and spectral analysis.
RESULT
Eight compounds were isolated and identified as apigenin (1), quercetin (2), oleanolic acid (3), 2alpha-hydroxyoleanolic acid (4), 2alpha-hydroxyursolic acid (5), protocatechuic acid (6), p-hydroxybenzoic acid (7), p-hydroxycinnamic acid (8).
CONCLUSION
Compounds 1-8 were isolated from R. roseum for the first time.
目的
研究玫瑰红叶藓的化学成分。
方法
通过重结晶以及硅胶柱色谱和葡聚糖凝胶LH - 20柱色谱对化合物进行分离和纯化。通过理化性质和光谱分析鉴定其结构。
结果
分离并鉴定出8种化合物，分别为芹菜素（1）、槲皮素（2）、齐墩果酸（3）、2α - 羟基齐墩果酸（4）、2α - 羟基熊果酸（5）、原儿茶酸（6）、对羟基苯甲酸（7）、对羟基肉桂酸（8）。
结论
化合物1 - 8首次从玫瑰红叶藓中分离得到。
