摘要: 利用超声-微波协同萃取技术提取槟榔籽油,采用紫外分光光度法快速测定所提取槟榔籽油的含量。通过单因素和响应面试验,考察提取时间、提取温度、液固比对槟榔籽油提取率的影响,确定了最佳提取工艺,结果表明:恒温模式、提取时间22min、温度65℃、液料比11:1(mL/g)条件下,槟榔籽油的提取率可达14.29%。槟榔籽油脂的气相色谱-质谱法分析表明,其主要成分为豆蔻酸33.50%、油酸20.40%、亚油酸19.19%、棕榈酸15.82%、月桂酸9.51%、硬脂酸1.59%。

Abstract: Betel nut oil was obtained by ultrasonic-microwave assisted extraction and its compositions were rapidly determined by a spectrophotometer. The extraction process conditions were optimized by response surface tests on the basis of single factor tests. According to the effects of extraction time, extraction temperature and material-liquid ratio on extraction rate of betel nut oil, the optimal extraction process parameters were extraction time of 22 min, extraction temperature of 65 ℃ and material-liquid ratio of 1:11 (g/mL). Under the optimal extraction process conditions, the extraction rate of betel nut oil was up to 14.29%. Gas chromatography analysis showed that the major compositions of betel nut oil were 33.5% myristic acid, 20.4% 9-octadecenoic acid, 19.19% 12-octadecadienoic acid, 15.82% hexadecanoic acid, 9.51% dodecanoic acid and 1.59% octadecanoic acid.

Key words: betel nut oil, ultrasound-microwave assisted extraction, response surface methodology (RSM), ultraviolet spectrophotometry, gas chromatography-mass spectrometry (GC-MS)
