摘要: 本实验对叶黄素衍生物的微生物转化进行了研究,主要考察了培养基种类、菌种、震荡培养与静置培养、pH值、菌种接种量等因素对叶黄素转化效果的影响,以双波长薄层色谱法进行定性、定量检测,优化出最佳转化条件:用pH值为3的诱导产酶培养基接种C菌(青霉属)6环,震荡培养15d,使得游离叶黄素的含量由0.25%提高到56.70%。采用硅胶柱层析对微生物转化产品进行分离纯化,得到最佳柱层析分离条件:上样量为0.5g;洗脱剂为石油醚:乙酸乙酯=3:2;流速为3ml/min,所得产品游离叶黄素纯度可达90.20%。

Abstract: In this research, biotransformation technology of lutein esters was investigated. Transformation effect of lutein was discussed according to various factors such as the type of culture medium, original strains, shock culture or quiescent culture, pH value and inoculation amount. Qualitative and quantitative determination of free lutein was performance by dual-wavelength TLC scanning method. The results showed that the optimal parameters were: inoculating original strains C (Penicillium) 6 rings in the revulsive culture medium at pH 3, shocking culture 15 days, and the content of free lutein could reach 56.70% in biotransformation product from 0.25% in the material. Then biotransformation product could be purified by silica gel column chromatography. The appropriate parameters were obtained as follow: 0.5g sample each time, V (petroleum ether):V(ethyl acetate)=3:2 was used as the eluting solvent at the eluent rate of 3 ml/min. Then the content of free lutein can reach 90.20%.
