摘要
用超临界ＣＯ２对桂花、茉莉花进行了萃取研究，考察萃取时间、温度、压力对浸膏得率和质量的影响。桂花萃取最佳工艺条件为：压力１２～１６ＭＰａ，温度３０８～３１８Ｋ，时间１５～２ｈ，浸膏得率０２５１％；茉莉花萃取最佳工艺条件为：压力１２～１５ＭＰａ，温度３０８～３２３Ｋ，时间１～１５ｈ，浸膏得率为０２４０％。
Osmanthus fragrans and Jasminum sambac were extracted with supercritical CO_2 at different conditions of pressure,temperature and contact time to estimate the yield and quality.The yield of Osmanthus concrete was 0.251% at better conditions of pressure range 12～16MPa,temperature range 308～318K and contact time 1.5～2h,and the yield of Jasminum concrete was 0.240% at better technological parameters of pressure range 12～15MPa,temperature range 308～323K and contact time 1～1.5h.The CO_2 extracts had higher yield and better quality compared with conventional extracts.
