摘要:

采用葡聚糖凝胶柱层析、硅胶柱层析等多种柱层析技术对冰菜乙醇提取物进行分离与纯化,根据所分离到化合物的核磁数据等鉴定其结构。从冰菜乙醇提取物中共分离鉴定9个化合物,其结构分别为:邻苯二甲酸二丁酯(1)、ixerol B(2)、环(苯丙-缬)二肽(3)、(1S,3S)-1-methyl-1,2,3,4-tetrahydro-β-carboline-3-carboxylic acid(4)、(1R,3S)-1-methyl-1,2,3,4-tetrahydro-β-carboline-3-carboxylic acid(5)、jasmioside E(6)、尿苷(7)、维生素B4(8)和紫丁香苷(9)。以上化合物均为首次从冰菜中分离得到,该研究丰富了冰菜的化学成分。细胞毒活性测试结果表明,以上化合物对宫颈癌细胞(Hela)、胃癌细胞(SGC-7901)、肺癌细胞(A549)、肝癌细胞(BEL-7402)和慢性髓原白血病细胞(K562)的增殖均无生长抑制活性。

Abstract:

The constituents of ethanol extract of M. crystallinum were isolated and purified with varied chromatographic techniques.All isolated compounds were identified on the basis of NMR data and physicochemical properties.Nine compounds were obtained and identified as dibutyl phthalate (1),ixerol B (2),cyclo-(Phe-Val) (3),(1S,3S)-1-methyl-1,2,3,4-tetrahydro-β-carboline-3-carboxylic acid (4),(1R,3S)-1-methyl-1,2,3,4-tetrahydro-β-carboline-3-carboxylic acid (5),jasmioside E (6),uridine (7),vitamin B4 (8) and syringin (9).All aforementioned compounds were isolated from M. crystallinum for the first time.This study enriched the chemical constituents of this plant.All above compounds showed no inhibitory activities towards human cervical carcinoma (Hela),human gastric adenocarcinoma (SGC-7901),human alveolar epithelium (A549),human hepatoma (BEL-7402) and chronic myelogenous leukemia (K562) cell lines.
