中文摘要: 紫娟茶由含酸甲醇提取后,经过乙醚、氯仿的液液分配以及 Amberlite XAD-7HP 树脂的吸附洗脱,得到花青素 粗提物。针对花青素提取物,采用金黄色葡萄球菌、大肠杆菌、酵母菌对花青素提取物的抑菌作用进行了检测。试验结果 显示,紫娟茶中花青素提取物浓度达到 10 %~20 %时对金黄色葡萄球菌抑菌能力较强,其次是大肠杆菌,但对酵母菌无 效果。本研究的结果为紫娟茶花青素的深入研究与有效开发利用,提供了必备的表征条件和理论依据,并有助于食品原 料的深度加工和功能性检测方法的应用与开发。
Abstract:Anthocyanins from Zi juan tea were exteacted by using acid-containing methanol as solvent and par- titioned with ether and chloroform. The extract of anthocyanins was purified by Amberlite XAD -7HP chro- matography. The antibacterial effects of anthocyanins extraction for Staphylococcus aureus, Escherichia coli and Saccharomyces cerevisiae were also tested. The results were that the concentration of anthocyanins in Zi juan Tea extract reaches 10 %-20 % of Staphylococcus aureus antibacterial ability was stronger, followed by Es- cherichia coli, but Saccharomyces cerevisiae has no effect. This study will provide scientific basis for developing and utilizating of Zi juan tea and contribute the depth of processing of food materials and functional application.
