摘　　要：为了优化超临界CO2萃取槟榔碱的工艺参数,通过三元二次通用旋转组合设计实施试验,考察了萃取温度、萃取压力和萃取时间因素对槟榔碱萃取量的影响。试验结果表明:超临界萃取的温度对槟榔碱萃取量有极显著的影响,萃取时间和压力的影响较小。同时确定了槟榔碱萃取的最佳工艺参数为萃取温度72℃,压力57MPa,时间26min。在此条件下,槟榔碱的萃取量为6143.71μg/g,达到理论最大萃取量的95.3%,所得萃取物中槟榔碱的百分含量为(25.85±0.41)%。In order to optimize technological parameters of arecoline extraction from areca nut using supercritical carbon dioxide extraction technique, the effects of extraction temperature, extraction pressure and extraction time on arecoline extraction were explored by second-order regression general rotation design. The results indicate that extraction temperature has a significant effect on the extraction quantity of arecoline, but extraction pressure or extraction time has a little effect. The optimum extraction parameters are as follows： extraction temperature 72℃, extraction pressure 57 MPa and extraction time 26 min. The maximum extraction quantity of coline is 6143.71μg/g under this condition and amounts to 95.3% of the maximum theoretical extraction quantity. The percent of arecoline in the supercritical carbon dioxide extract is （25.85±0.41）%.
