摘 要:旨在高效生产刺五加叶中黄酮类成分。分别采用乳酸杆菌及酿酒酵母发酵刺五加叶,以金丝桃苷及槲皮素为指标,采用HPLC法,观察其发酵后含量的动态变化,并在此基础上,对刺五加叶发酵样品中黄酮成分采用D101大孔树脂柱及硅胶柱色谱进行分离。结果表明,经乳酸杆菌发酵后,刺五加叶中金丝桃苷含量显著降低,由4.00±0.15(mg/g)降低到1.71±0.09(mg/g),槲皮素含量显著增加,由0.03±0.33(mg/g)增加到0.437±0.15(mg/g);经酿酒酵母发酵后,其金丝桃苷及槲皮素含量均显著增加,金丝桃苷含量由4.00±0.15(mg/g)增加到5.97±0.48(mg/g),槲皮素含量由由0.03±0.33(mg/g)增加到1.40±0.65(mg/g)。经柱色谱分离,从刺五加叶发酵样品中分离得到了金丝桃苷及槲皮素。研究结果可为采用酿酒酵母发酵刺五加叶定向高产金丝桃苷及槲皮素及探讨黄酮类成分生物合成机制提供参考。The aim is to produce flavonoids in Acanthopanax acanthopanax leaves efficiently.Acanthopanax acanthopanax leaves were fermented by Lactobacillus and Saccharomyces cerevisiae respectively,hypericin and quercetin were used as indexes to observe the dynamic changes of their contents after fermentation by HPLC.On this basis,the flavonoids in Acanthopanax acanthopanax leaves were separated by D101 macroporous resin column and silica gel column chromatography.The results showed that after lactobacillus fermentation,the content of hypericin in Acanthopanax acanthopanax leaves decreased significantly from 4.00±0.15(mg/g)to 1.71±0.09(mg/g),and the content of quercetin increased significantly from 0.03±0.33(mg/g)to 0.437±0.15(mg/g).The contents of hypericin and quercetin were significantly increased after fermentation with Saccharomyces cerevicae.Hypericin content increased from 4.00±0.15(mg/g)to 5.97±0.48(mg/g),quercetin content increased from 0.03±0.33(mg/g)to 1.40±0.65(mg/g).Hypericin and quercetin were isolated from fermented Acanthopanax acanthopanax leaves by column chromatography.The results of this study can provide reference for the fermentation of Acanthopanax acanthopanax leaves by Saccharomyces cerevisiae to yield hypericin and quercetin in a directional manner and to explore the biosynthesis mechanism of flavonoids.
