Abstract Camellia oleifera Abel. ( Camellia oleifera ) seeds oil and tea saponin were simultaneously extracted under subcritical water extraction (SWE) conditions. A response surface methodology (RSM) was used for optimizing the SWE process by varying independent variables temperature (×1: 110–150 °C), extraction time (×2: 20–40 min) and solvent to material ratios (×3: 5:1–15:1 mL/g). The highest extraction yield of oil is 94.07% at the condition of 133.59 °C, 32.03 min, 10.79 mL/g with the tea saponin yield 71.38%, and the highest extraction yield of tea saponin is 74.21% with the oil yield 91.27% of the total content at the condition of 121.11 °C, 32.07 min, 8.33 mL/g. Analytical results showed that extracted oil has a similar fatty acid profile and quality as those of the cold Soxhlet extraction(SE) oils, and the oils extracted by SWE were even more resistant to lipid oxidation and more abundant valuable bioactive compounds than those of the cold-pressed(CP) oils.

从油茶中同时提取油茶皂苷。亚临界水条件下的种子

摘要山茶花阿贝尔。(Camellia oleifera) 种子油和茶皂苷在亚临界水提取 (SWE) 条件下同时提取。响应面方法 (RSM) 用于通过改变自变量温度 (×1: 110–150 °C)、提取时间 (×2: 20–40 分钟) 和溶剂与材料比 (×3: 5:1–15:1 毫升/克）。在133.59 ℃、32.03 min、10.79 mL/g条件下，油的最高提取率为94.07%，茶皂苷得率为71.38%；茶皂苷的最高提取率为74.21%，出油率为91.27%。 121.11℃，32.07min，8.33mL/g条件下的总含量。分析结果表明，提取的油具有与冷索氏提取 (SE) 油相似的脂肪酸谱和质量，
