摘要:

研究天南星科海芋属植物尖尾芋 Alocasia cucullata (Lour.) Schott石油醚部位化学成分。采用硅胶、Sephadex LH-20等色谱方法进行分离纯化,运用波谱学技术进行结构鉴定。采用CCK-8法测试化合物对人乳腺癌MDA-MB-231、MCF-7细胞及小鼠乳腺癌4T1细胞的体外细胞毒活性。从尖尾芋根茎石油醚部位中分离得到15个化合物,分别为对羟基苯甲醛(1)、苯甲酸(2)、香草酸乙酯(3)、没食子酸乙酯(4)、7-羟基香豆素(5)、肉豆蔻酸甲酯(6)、角鲨烯(7)、齐墩果酸(8)、熊果酸(9)、香紫苏醇(10)、香紫苏内酯(11)、原儿茶醛(12)、原儿茶酸(13)、二十八烷醇(14)和没食子酸(15),化合物2~15为海芋属首次分离得到,所有化合物均为尖尾芋首次分离得到。乳腺癌细胞毒活性研究显示:化合物489对3种乳腺癌细胞均有一定的抑制作用。

Abstract:

To study the chemical constituents of the petroleum ether extract from Alocasia cucullata (Lour.) Schott,a plant species belonging to the Araceae family.Silica gel,Sephadex LH-20 and other chromatographic methods were used for separation and purification,and spectroscopic techniques were employed for structural identification.The in vitro assessment of all isolated compounds was conducted using the CCK-8 assay on human breast cancer cell lines MDA-MB-231 and MCF-7,as well as mouse breast cancer cells 4T1.Fifteen compounds were isolated from the petroleum ether fraction of the rhizome of A. cucullata and their structures were identified as p-hydroxybenzaldehyde (1),benzoic acid (2),ethyl vanillate (3),ethyl gallate (4),7-hydroxycoumarin (5),myristate (6),squalene (7),oleanolic acid (8),ursolic acid (9),sclareol (10),sclareolide (11),protocatechualdehyde (12),protocatechuic acid (13),octacosanol (14) and gallic acid (15).Compounds 2-15 were first isolated from genus Alocasia.All the compounds were first isolated from A. cucullata.The cytotoxicity study of breast cancer cell showed that compounds 4,8 and 9 had inhibitory effect on all three kinds of breast cancer cell lines.

Key words: Alocasia cucullata (Lour.) Schott, chemical composition, structure identification, breast cancer, cell cytotoxicity
