The phytochemical study of ethyl acetate and n-butanol extracts of Pteranthus dichotomus Forssk. led to the isolation and identification of 11 compounds, including three glycolipids 1-3, one lignan 4, three flavonoids 5-7 and four phytosterols 8-11. Structures of the isolated compounds have been elucidated by analysis of 1D and 2D NMR data, and mass spectrometry EI-MS and ESI-MS and by comparison with literature data. Furthermore, the ethyl acetate and n-butanol extracts were examined for their antioxidant and antibacterial activities. The results showed that both extracts (PDAC and PDBU) had a moderate antioxidant activity (IC50 = 375.514 μg/mL and 691.333 μg/mL) respectively.
对二歧翼萼（Pteranthus dichotomus Forssk.）乙酸乙酯提取物和正丁醇提取物的植物化学研究，导致分离并鉴定出11种化合物，包括三种糖脂1 - 3、一种木脂素4、三种黄酮类化合物5 - 7和四种植物甾醇8 - 11。通过一维和二维核磁共振数据、质谱电子轰击质谱（EI-MS）和电喷雾电离质谱（ESI-MS）分析，并与文献数据比较，阐明了分离出的化合物的结构。此外，还检测了乙酸乙酯提取物和正丁醇提取物的抗氧化和抗菌活性。结果表明，两种提取物（PDAC和PDBU）分别具有中等抗氧化活性（IC50 = 375.514 μg/mL和691.333 μg/mL）。
