摘要
采用加速溶剂萃取法和索氏提取法从金银花中提取浸膏,并以芦丁为标准品,建立了芦丁标准工作曲线的回归方程:A=0.00731×C-0.0021,相关系数r=0.9997。计算了浸膏中黄酮类化合物的含量。ASE法提取的浸膏黄酮含量为15.58%,索氏提取的浸膏中黄酮含量为11.42%。金银花浸膏在卷烟中进行了加香试验,金银花浸膏具有显著改善卷烟吸味、减轻刺激性作用。
The accelerated solvent extraction and soxhlet extraction methods were employed in extracting flavonoids of Honeysuckle, turin was taken as the standard sample, the regression equation of rutin standard working curve： A（mg/L）= 0.007256×C- 0.0021 was established, the correlation coefficient was r - 0.9997. The total flavoncids content was 15.58 % in extraction from ASE and 11.42 % in extraction from soxhlet extraction. The extract was used as cigarette addictive, and the smoking quality of cigarette was obviously improved.
