摘　　要：本文对胡萝卜中胡萝卜素的超临界CO2提取条件进行研究。分别对不同压力、 温度及夹带剂等几个影响因素进行试验。确定了最佳提取条件为压力5000psi(340大气 压),温度60℃,二氧化碳流量1.5L/min,时间4h。Carrots were extracted with supercritical fluid carbon dioxide under various combinations of pressure and temperature and analysed for their carotene content by UV - spectrometer. The high extraction rate was obtainde under the following parameters: 5000psi of pressure, 60℃of temperature, 15 L/min of flow rate with the extraction time of 4 hours.
