摘要
在芡实栲胶提取中初步研究结果表明 :在使用 6 5 %的乙醇的水溶液 ,粒度为 0 .3cm方块 ,浸提温度选择在 5 5℃ ,浸出时间选择在 2h ,乙醇水溶液中的水应使用蒸馏水 ,加入适量的表面活性剂 ,浸提液的酸碱性为中性等条件下可得到栲胶 9%～ 13%。
The optimum conditions for extracting the vegetable tannin extract from Pericarp of Semen Euryales were; 65%(volume percent) ethanol as extractant by surfactant, temperature 55℃, time 2 h,pH=6-7 of 65% (volume percent) ethanol as extractant, using distilled water of 65% ethanol as extractant, granularity 0.3 cm, join appropriate surfactant. The results showed that Tannins from Pericarp of Semen Euryales of 9%-13% was extracted.
