摘要: 采用正相硅胶柱色谱、反相硅胶柱色谱、凝胶柱色谱等方法对来自大象粪便的链霉菌YIM801的发酵产物进行分离,共获得11个化合物,依据理化性质及波谱数据分析,分别鉴定为环(苯丙氨酸-缬氨酸)(1)、环(亮氨酸-缬氨酸)(2)、N-乙酰色胺(3)、N-乙酰酪胺(4)、5′-O-乙酰胸苷(5)、2′-脱氧尿苷(6)、2-吡咯甲酸(7)、2,5二羟基苯甲醇(8)、2,5二羟基苯甲醇甲醚(9)、2甲氧基对苯二酚(10)和间羟基苯甲醇(11)。所有化合物均为首次从大象粪便来源的链霉菌中分离得到。

Abstract: Eleven compounds were obtained from the fermentation broth of the strain Streptomyces sp. YIM801, which was isolated from Elephas maximus feces,by using silica gel,RP-18,and Sephadex LH-20 column chromatography.On the basis of spectral data and physicochemical properties,their structures were identified as cyclo-(Phe-Val) (1), cyclo-(Leu-Val) (2), N-acetyltryptamine (3), N-acetyltyramine (4), 5′-O-acetylthymidine (5), 2′-deoxyuridine (6), 2-minaline (7), 2,5-dihydroxybenzyl alcohol (8), 2,5-dihydroxy benzene methanol methyl ether (9), 2-methoxyhydroqunone (10),hydroxybenzyl alcohol (11).All of the compounds were isolated from Streptomyces sp.from Elephas maximus feces for the first time.

Key words: Streptomyces sp., Elephas maximus;animal feces;secondary metabolites
