摘 要:以茅巖莓茶為原料,采用不同體積分數的乙醇水溶液提取其中的黃酮類(lèi)化合物,并用單因素和正交實(shí)驗,依次考察乙醇體積分數、料液比、浸提溫度以及浸提時(shí)間對黃酮提取率的影響,確定優(yōu)化工藝參數。結果表明,當乙醇體積分數80%,料液比1∶20,浸提溫度80℃和浸提時(shí)間4 h時(shí),黃酮類(lèi)化合物的提取率最高。 |

Abstract:Ethanol solution of different volume fraction was adopted to extract flavonoid from Maoyan berry tea, a raw material used in this research. Single factor experiment and orthogonal experiment were combined to investigate the effects of different volume fraction of ethanol, solid-liquid ratio and temperature and time of extraction on the extraction efficiency of flavonoid to obtain the optimum process parameter. The results indicated that the extraction efficiency of flavonoid reached its highest level at the volume fraction of ethanol of 80%, solid-liquid ratio of 1∶20, extraction temperature of 80℃ and extraction time of 4 h. |
Key words:flavonoids; maoyan berry tea; extract |
