摘要: 以酵母提取物(yeast extract,YE)作为外加诱导子对欧洲花楸悬浮细胞(Sorbus aucuparia suspension cell,SASC)产生生物胁迫作用并对胁迫环境下产生的悬浮细胞次生代谢产物进行分离鉴定及抑菌活性研究。运用正相硅胶、Sephadex LH-20、半制备型HPLC等色谱方法及现代波谱技术,从SASC甲醇提取物中分离鉴定了13个化合物,分别为:eriobofuran(1)、4,5-dihydroxy-3-methoxybiphenyl(2)、2′-hydroxyaucuparin(3)、aucuparin(4)、trans-cinnamic acid(5)、citrostadienol(6)、β-谷甾醇(7)、uvaol(8)、白桦脂酸(9)、tormentic acid(10)、alphitolic acid methyl ester(11)、fupenzic acid(12)、亚油酸(13)。其中,化合物5~13为首次从SASC中分离得到。选择化合物1~3、5、812对15种植物病原真菌进行抑菌活性测试,其中联苯类化合物1和2对苹果轮纹菌具有显著的抑制活性,MIC分别为3.13和6.25 μg/mL。

Abstract: The aim of this research was to investigate the chemical constituents of Sorbus aucuparia suspension cell (SASC) elicited by yeast extract (YE) and their antifungal activity.13 compounds were obtained from the methanolic extracts of SASC by semi-prep.HPLC and column chromatography on silica gel,Sephadex LH-20.On the basis of spectroscopic analysis,the isolated compounds were identified as eriobofuran (1),4,5-dihydroxy-3-methoxybiphenyl (2),2′-hydroxyaucuparin (3),aucuparin (4),trans-cinnamic acid (5),citrostadienol (6),β-sitosterol (7),uvaol (8),betulinic acid (9),tormentic acid (10),alphitolic acid methyl ester (11),fupenzic acid (12),and linoleic acid (13).Compounds 5-13 were isolated from SASC for the first time. Compounds 1-3,5,8 and 12 was evaluated for their antifungal activity against 15 plant pathogenic fungi and biphenyls 1 and 2 exhibited significant inhibitory effects on Physalospora piricola Nose,with MIC values of 3.13 and 6.25 μg/mL,respectively.
