Optimization of Ultrasound-Assisted Extraction of Comus officinalis Seed Oil by Response Surface Methodology and Chemical Composition Analysis
摘要
Abstract
Abstract： Response surface methdology was employed to optimize the ultrasound-assisted extraction of Comus officinalis seed oil. Meanwhile, its chemical composition was analyzed by GC-MS. The optimal extraction conditions were determined as 40 ℃ of extracion temperatrure, 40 rain of extraction time, and 10：1 of liquid-to-solid raio （mL/g）. Under these conditions, the extraction yield of Comus officinalis seed oil based on the dry weight of Comus officinalis kernels was 7.90%, accounting for 97.08% of that obtained from Soxhlet extraction. The predominant fatty acids in Comus officinalis seed oil were oleic acid （61.89%）, stearic acid （19.99%）, palmitic acid （7.63%）, linoleic acids （6.33%）, and so on. The percentage of unsaturated fatty acids relative to total fatty acids was 69.45%. In addition, the vitamin E content in Comus officinalis seed oil, as determined by HPLC, was 76.0 mg/100 g.关键词
