摘要: 选择30%穿心莲内酯浸膏为原料,采用溶剂预浸提法,探讨了超临界CO2萃取结晶前处理工艺中溶剂种类、液固比、浸提温度、浸提时间、浸提次数的作用规律。结果表明:超临界CO2萃取结晶穿心莲内酯前处理工艺中选择了乙酸乙酯作为溶媒,液固比为6:1,浸提温度50℃,时间3h,次数2次,获得较优工艺,所得浸膏中穿心莲内酯的纯度在45%以上,浸提率超过85%。

Abstract: Extraction of Andrographis paniculata (Burm.f.) Nees (purity of andrographolide 30%) was investigated for the sorts of solvent, ratio of liquid to solid, extraction temperature, extraction hours and extraction times in technology. The results showed that the ethyl acetone is the optimal solvent with the technology parameters as: ratio of liquid to solid 6:1, extraction temperature50℃, extraction time 3 hours and extraction 3 times. The extract of Andrographis paniculata(Burm.f.) Nees with more than 45% purity of andrographolide and more than 85% extraction ratio can be achieved.
