Abstract
Four diketopiperazine derivatives; cyclo(-Pro-Val) (1), (-)-cyclo(-Pro-Tyr) (2), (-)-cyclo(-Pro-Phe) (3) and (+)-cyclo(-Pro-Leu) (4) were isolated from the ethyl acetate extract of Glaciozyma antarctica PI12, a cold-adapted yeast that belongs to family Kriegeriales. The compounds were isolated by radial chromatography and thin layer chromatography techniques and the chemical structures were elucidated by infrared (IR), ultraviolet (UV), nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry.
四种双酮哌嗪衍生物;从Kriegeriales科冷适应酵母Glaciozyma antarctica PI12的乙酸乙基提取物中分离得到cyclo(- pro - val)(1)、(-)-cyclo(- pro - tyr)(2)、(-)-cyclo(- pro - phe)(3)和(+)-cyclo(- pro - leu)(4)。采用径向色谱和薄层色谱分离得到化合物，并用红外(IR)、紫外(UV)、核磁共振(NMR)和质谱分析鉴定了化合物的化学结构。
