In this study, ultrasound-assisted extraction (UAE) was applied to extract bioactive substances with skin-whitening, anti-wrinkle, and antioxidant effects from safflower seeds, and the extraction conditions were optimized by a central composite design. The independent variables, including extraction time (5.055.0 min), extraction temperature (26.094.0 °C), and ethanol concentration (0.0~100%), were optimized to increase tyrosinase activity inhibitory (TAI), collagenase activity inhibitory (CAI), and radical scavenging activity (RSA), which are indicators of skin-whitening, anti-wrinkle, and antioxidant effects. An extraction time of 26.4 min, extraction temperature of 52.1 °C, and ethanol concentration of 50.7% were found to be optimum conditions of UAE, under which TAI, CAI, and RSA were 53.3%, 91.5%, and 27.7%, respectively. The extract produced by UAE was analyzed by LC-MS/MS, and maleic acid and levulinic acid were identified as the main substances. Therefore, UAE is evaluated as an effective process to extract skin-whitening, anti-wrinkle, and antioxidant substances from safflower seeds at lower temperatures and shorter extraction times compared to the conventional extraction methods. Overall, safflower seeds extract can be used as a material for value-added cosmetics, including maleic acid and levulinic acid, which have bioactive functions.
在这项研究中,超声辅助提取(UAE)被应用于从红花种子中提取具有美白、抗皱和抗氧化作用的生物活性物质,并通过中心复合设计优化了提取条件。独立变量包括提取时间(5.055.0 分钟)、提取温度(26.094.0°C)和乙醇浓度(0.0~100%),以提高酪氨酸酶活性抑制率(TAI)、胶原酶活性抑制率(CAI)和自由基清除活性(RSA),这是美白、抗皱和抗氧化作用的指标。发现提取时间为 26.4 分钟、提取温度为 52.1°C、乙醇浓度为 50.7%是 UAE 的最佳条件,在此条件下 TAI、CAI 和 RSA 分别为 53.3%、91.5%和 27.7%。通过 LC-MS/MS 对 UAE 产生的提取物进行分析,鉴定出马来酸和乙酰丙酸是主要物质。因此,与传统提取方法相比,UAE 被评估为一种在较低温度和较短提取时间内从红花种子中提取美白、抗皱和抗氧化物质的有效工艺。总的来说,红花籽油提取物可以作为具有生物活性功能的增值化妆品的原料,包括马来酸和乙酰丙酸。
