中文摘要：

对巴豆地上部分的化学成分进行研究，采用反复硅胶，葡聚糖凝胶，ODS以及制备型高效液相色谱技术进行分离纯化。通过质谱和一维，二维核磁共振波谱方法鉴定其结构。从中共分离并鉴定了10个佛波内酯类化合物，分别为两个新化合物2．甲基丁酸酯-13-异丁酸酯-4叶去氧佛波内酯（1），20．甲酰基-13-乙酸酯-4α-去氧佛波内酯（10）和8个己知化合物：12-乙酸酯-13-（2-甲基）丁酸酯-4α-去氧佛波内酯，12-巴豆酯-13．乙酸酯-4a-去氧佛波内酯，12-巴豆酯-13-（2-甲基）丁酸酯-4α-去氧佛波内酯，12-（2-甲基）丁酸酯-13-乙酸酯-4a-去氧佛波内酯，12-巴豆酯-13-异丁酸酯4α-去氧佛波内酯，12-巴豆基-13-（2-甲基）丁酸酯佛波内酯，12-巴豆酯基-13-乙酸酯佛波内酯，12-巴豆酯基-7-氧化-5-烯基-13-（2-甲基）丁酸酯佛波内酯。

英文摘要：

To investigate the phytochemical constituents of aboveground parts of Croton tiglium L. （family Euphorbiaceae）, its ingredients were isolated by repeated chromatography on silica gel, Sephadex LH-20, ODS and preparative HPLC. Their structures were identified based on 1D, 2D NMR and mass spectral analysis. A total of 10 phorbol esters were obtained. Among them, compound 1 （12-O-（2-methyl）butyryl-4ct-deoxyphorbol-β-isobutyrate） and compound 10 （20-formyl-4a-deoxyphorbol- β-acetate） were two new compounds, and the other eight were known compounds.
