摘要
为阐明意大利牛舌草药效物质基础,本研究采用硅胶柱色谱、半制备型高效液相色谱技术等对意大利牛舌草70%乙醇提取物的乙酸乙酯部位进行分离纯化,通过NMR、MS等现代波谱学方法鉴定所得化合物的结构,从中共分离鉴定了19个化合物,分别为:羟基酪醇(1)、咖啡酸乙酯(2)、3,4-二羟基苄胺(3)、对羟基苯甲酸(4)、香草醛(5)、1,2,4-苯三酚(6)、原儿茶醛(7)、(E)-4-(2-hydroxyvinyl)-2-methoxyphenol(8)、原儿茶酸(9)、异鼠李素(10)、丙三醇(11)、对羟基苯甲醛(12)、咖啡因(13)、caffeic acid ethylene ester(14)、原儿茶酸乙酯(15)、phenylethylβ-D-glcoside(16)、benzylβ-D-glucopyranoside(17)、3,4-dihydroxyphenyl caffeate(18)、山柰酚-3-O-芸香糖苷(19)。化合物1~3、6~8、12~18为首次从该植物中分离得到,其中10个化合物(1、3、6~8、13~17)为首次从牛舌草属中分离得到。同时采用脂多糖诱导的RAW 264.7细胞炎症模型,以吲哚美辛作为阳性对照,测定各化合物的体外抗炎活性。结果显示,化合物1、2、10、13抗炎活性相对较好,IC_(50)值分别为19.6、14.9、11.3、10.2μmol/L。
To elucidate the material basis of the pharmacological effects of Anchusa italica Retz.,the study was carried out to isolate and purify the chemical components from the ethyl acetate site of 70%ethanol extract of the plant by silica gel and semi-preparative high-performance liquid chromatography and identify the structures of the compounds by modern spectroscopic methods such as NMR,MS,and so on.Nineteen compounds were isolated and identified as:hydroxytyrosol(1),ethyl caffeate(2),3,4-dihydroxybenzylamine(3),4-hydroxybenzoic acid(4),vanillin(5),1,2,4-benzenetriol(6),3,4-dihydroxyphenylacetaldehyde(7),(E)-4-(2-hydroxyvinyl)-2-methoxyphenol(8),protocatechuic acid(9),isorhamnetin(10),glycerol(11),4-hydroxybenzaldehyde(12),caffeine(13),caffeic acid ethylene ester(14),ethyl 3,4-dihydroxybenzoate(15),phenylethylβ-D-glcoside(16),benzylβ-D-glucopyranoside(17),3,4-dihydroxyphenyl caffeate(18),kaempferol-3-O-rutinoside(19).Compounds 1-3,6-8,12-18 were isolated from this plant for the first time,among which 10 compounds(1,3,6-8,13-17)were isolated for the first time from the genus Anchusa L..Meanwhile,the in vitro activities of the compounds were determined by using the lipopolysaccharide-induced RAW 264.7 cell inflammation model,with indomethacin as the positive control.The bioactivity results showed that compounds 1,2,10,and 13 had relatively high anti-inflammatory activities with IC_(50) values of 19.6,14.9,11.3,and 10.2μmol/L.
