To investigate the chemical constituents of peanut hull.
Several chromatography methods such as silica gel and Sephadex LH-20 combined with recrystallization were applied to isolate the compounds. Based on spectrum technologies (MS,1H-NMR and 13C-NMR) and physico-chemical methods, structures of isolated compounds were identified.
Twelve compounds were isolated and elucidated as luteolin (1), diosmetin (2), 5,7,3',4'-tetrahydroxy-8-prenyflavone (3),5,7,3'-trihydroxy-4'- methoxy-8-prenylflavone(4), eriodicrtyol (5), racemoflavone (6), hydnocarpin (7), 5,7-dihydroxy chromone (8), 5-hydroxy-chromone- 7-O-β-D-glucoside (9), ferulic acid (10), β-sitosterol (11) and daucosterol(12).
Except compounds 1, 5 and 8, all compounds are obtained from peanut hull for the first time.
研究花生壳的化学成分。
采用硅胶、葡聚糖凝胶LH - 20等多种色谱方法并结合重结晶法分离化合物。基于光谱技术（质谱、氢核磁共振谱和碳核磁共振谱）以及物理化学方法鉴定分离得到的化合物结构。
分离并鉴定出12种化合物，分别为木犀草素（1）、香叶木素（2）、5,7,3',4'-四羟基-8-异戊烯基黄酮（3）、5,7,3'-三羟基-4'-甲氧基-8-异戊烯基黄酮（4）、圣草酚（5）、消旋黄酮（6）、氢化卡波林（7）、5,7-二羟基色酮（8）、5-羟基色酮-7 - O-β-D-葡萄糖苷（9）、阿魏酸（10）、β-谷甾醇（11）和胡萝卜苷（12）。
除化合物1、5和8外，其余化合物均首次从花生壳中获得。
