| 摘 要： | 目的:研究毛蚶的抗菌活性部位及有效成分。方法:毛蚶软组织经乙醇提取后,采用液液萃取法将提取物分为石油醚相、乙酸乙酯相、正丁醇相和水相4个不同的极性部位;采用抑菌圈法和最小杀菌浓度测定法,对毛蚶乙醇提取物和各极性部位进行了抗菌活性测定,并用正相硅胶柱对抗菌活性较好的石油醚相进行了分离纯化,得到甾体组分;采用GC-MS技术对石油醚相和甾体组分进行了化学成分分析。结果:毛蚶石油醚相的抑菌效果最好;从毛蚶石油醚相中鉴定出了30个化合物,主要为脂肪类和甾醇类化合物;从甾体组分中鉴定出8个化合物,其中7个为首次从毛蚶中分离鉴定。结论:毛蚶的石油醚相具有明显的抗菌活性,石油醚相以甾醇类化合物为主。

| Abstract: | Objective: To screen the antibacterial fractions and constituents of Scapharca subcrenata Lischke.Methods: The soft tissues of S.subcrenata was extracted by ethanol.Liquid- liquid extraction with petroleum ether, ethyl acetate, n- butanol and water was used for the separation of ethanolic extract and 4 organic fractions were obtained.The antibacterial activities of the ethanolic extract and organic fractions was evaluated by diameter of inhibition zone ( DIZ) and the minimum bactericidal concentration ( MBC) . The active petroleum ether fraction was separated and purified with silica gel column chromatography, and a sterol mixture was obtained.The compounds in the petroleum ether fraction and the sterols were analyzed by gas chromatography- mass spectrometry ( GCMS) .Results: The antibacterial substances were mainly in the petroleum ether fraction, and 30 compounds were identified by GC- MS, most of which were 1ipids and sterols.Eight compounds were identified by GC- MS from the sterol component, and seven compounds were identified for the first time from S. subcrenata. Conclusion: The antibacterial activities of petroleum ether fraction from S. subcrenata were obvious, and sterol was the major compound of petroleum ether fraction. |
