摘　　要：目的:优选丹参提取液絮凝澄清工艺。方法:采用单因素实验法,以澄清处理后的丹参提取液的浊度和指标成分丹酚酸B、丹参素、原儿茶醛含量为考察对象,优选两种絮凝澄清剂的用量和絮凝温度。结果:使用壳聚糖进行絮凝澄清处理后的丹参水提液上清液浊度低于用ZTC1+1Ⅱ型絮凝剂处理后的浊度,并能够更好地减轻膜污染程度。结论:壳聚糖作为丹参水提液絮凝澄剂效果优于ZTC1+1Ⅱ型絮凝剂。AIM： To optimize the flocculation-clarification process of Danshen aqueous extract. METHODS： Based on the single factor experiment, the turbidity of the index components danshensu, protecatechnic aldehyde concentration in the Danshen aqueous extract after flocculation were choose among the kinds and amount of flocculant and flocculation temperature. RESULTS ： The turbidity of the chitosan-treated supernatant was lower than that of the ZTC1 ＋ 1Ⅱ-treated ones, and this treatment can mitigate the membrane fouling better. CONCLUSION： Chitosan is superior to ZTC1 ＋ 1 Ⅱas the flocculant of the Danshen aqueous extract.
