【摘要】 以醉蝶花种子为研究材料,用超声波提取技术对醉蝶花种子成分进行提取,通过单因素试验和正交试验探究了不同的提取时间、提取温度和料液比等因素对提取率的影响,用气相色谱-质谱分析(gas chromatography-mass spectrometry,GC-MS)技术对提取物进行分析检测.结果表明,在固定超声功率为300 W,提取时间为24 min,提取温度为38℃,料液质量体积比(g/mL)为1∶12的提取条件下,醉蝶花种子成分提取率可达17.84%.醉蝶花种子用丙酮作浸提剂的超声波提取法提取的主要物质是醇类化合物,含量高达66.48%.超声波提取法操作简便,效率高,成本相对较低,是一种对醉蝶花种子有效成分提取的可行方法.更多还原

【Abstract】 The components of the spiderflower seeds were extracted by ultrasonic technology, with single factor and orthogonal experiments, the influence of different extraction time, extraction temperature and material to liquid ratio were studied, and the extraction analyzed by GC-MS. The results show that under the conditions of ultrasonic power 300 W, extraction time 24 min, extraction temperature 38 ℃ and ratio of material to liquid 1:12, the extraction rate of the spiderflower seeds was 17.84%. The main substance extracted by ultrasonic method with acetone was the alcohol as content of 66.48%. The ultrasonic extraction method is simple, high efficiency and low cost. It is a feasible method to extract the effective components from the seeds of spiderflower seeds.更多还原
