摘要
以生姜为原料，研究了超声强化提取生姜总黄酮的工艺条件。以生姜提取物中总黄酮为考察指标，用单因素和正交实验研究提取的最佳工艺。结果表明：以80％乙醇溶液为溶剂，提取时间60min，物料比1：20（g／mL）时，提取效果最好，此条件下的生姜总黄酮得率可达1．27％。
The uhrasonic-enhancement technology of total-flavones extraction in gingers was studied in this paper, and the optimal technological conditions were obtained by single factor and orthogonal experiments. The results demonstrate d that the total-flavones yield achieved 1.27% by extracting with 80% alcohol the solution containing gingers for 60 min with the materials ratio of 1 ： 20 （g/mL）.
