摘要:

基于脂多糖(LPS)诱导的小鼠巨噬细胞(RAW 264.7)生物模型研究丁香茄Calonyction muricatum叶乙酸乙酯部位的抗炎活性成分。在体外活性追踪下,采用硅胶、MCI、ODS、HW-40C柱色谱及半制备液相等方法对乙酸乙酯活性部位进行分离纯化,根据理化性质结合现代波谱技术鉴定化合物结构。从丁香茄叶乙酸乙酯部位分离得到15个化合物,分别为:12-oxo-phytodienoic acid(1)、(9Z,12Z,14E,16R)-16-hydroxyoctadeca-9,12,14-trienoic acid(2)、(9Z,12S,13Z,15Z)-12-hydroxyoctadeca-9,13,15-trienoic acid methyl ester(3)、(9Z,11Z,13R,15Z)-13-hydroxyoctadeca-9,11,15-trienoic acid(4)、(9R,10E,12Z)-9-hydroxyoctadeca-10,12-dienoic acid(5)、(9S,10Z,12Z)-9-hydroxyoctadeca-10,12-dienoic acid(6)、1-十二烷醇(7)、山柰酚-3-O-半乳糖苷(8)、6-methoxykaempferol-3-O-galactoside(9)、紫云英苷(10)、6-methoxykaempferol-3-O-glucoside(11)、(6S,9R)-长寿花糖苷(12)、咖啡酸乙酯(13)、麦芽酚(14)、hydroxydihydrobovolide(15)。化合物1~121415为首次从月光花属植物中分离得到。单体化合物抗炎活性筛选结果表明,化合物1345均具有一定的抗炎活性,其中15的抑制NO作用显著,IC50值分别为1.17 ± 0.51、0.97 ± 0.89 μM。

Abstract:

To study the anti-inflammatory constituents from the EtOAc extract of Calonyction muricatum leaves based on lipopolysaccharide (LPS)-induced mouse macrophages (RAW 264.7) as the cell model in vitro.Under the guidance of bioactivity screening,the phytochemistry investigation of active EtOAc extract was carried out by silica gel,MCI,ODS,HW-40C column chromatography and semi-prep HPLC methods.The structures of isolated compounds were identified on the basis of physicochemical properties and modern spectroscopy technologies.A total of 15 compounds were obtained from C. muricatum leaves,including 12-oxo-phytodienoic acid(1),(9Z,12Z,14E,16R)-16-hydroxyoctadeca-9,12,14-trienoic acid(2),(9Z,12S,13Z,15Z)-12-hydroxyoctadeca-9,13,15-trienoic acid methyl ester(3),(9Z,11Z,13R,15Z)-13-hydroxyoctadeca-9,11,15-trienoic acid(4),(9R,10E,12Z)-9-hydroxyoctadeca-10,12-dienoic acid(5),(9S,10Z,12Z)-9-hydroxyoctadeca-10,12-dienoic acid(6),1-dodecanol (7),kaempferol-3-O-galactoside (8),6-methoxykaempferol-3-O-galactoside (9),astragaline (10),6-methoxykaempferol-3-O-glucoside (11),(6S,9R)-roseoside (12),ethyl caffeate (13),maltol (14) and hydroxydihydrobovolide (15).Among them,compounds 1-12,14 and 15 were isolated from the genus Calonyction for the first time.Additionally,the bioassay results showed that compounds 1,3,4 and 5 all had certain anti-inflammatory actions.Compounds 1 and 5 significantly inhibited NO production with IC50 values of 1.17 ± 0.51 and 0.97 ± 0.89 μM respectively.
