        摘  要   目的 优化天然低共熔溶剂(NADESs)提取肉苁蓉中苯乙醇苷类成分的工艺,为肉苁蓉的开发和利用提供参考。方法 首
        先,以松果菊苷、毛蕊花糖苷和异毛蕊花糖苷的总提取效率为指标,筛选NADESs的类型;然后,在单因素实验基础上,通过响应曲
        面法优选最佳NADESs组成成分的摩尔比、NADESs含水量和液料比,并通过遗传算法对结果进行优化。以维生素C(VC)为阳性
        对照,从提取效率、体外抗氧化活性2个方面比较NADESs和传统溶剂(50%甲醇)的提取效果。结果 最佳提取溶剂为由1,4-丁二
        醇和丙二酸组成的NADES-11。最优提取工艺为:NADES-11中1,4-丁二醇和丙二酸的摩尔比1 ∶ 2.5、NADES-11含水量18%、液
        料比30 mL/g、提取时间30 min、提取温度30 ℃。NADES-11的提取效率显著高于50%甲醇(P<0.05);NADES-11提取物对1,1-
        二苯基-2-三硝基苯肼自由基和羟基自由基的半数清除浓度(261.17、744.34 µg/mL)均低于50%甲醇提取物(420.97、1 175.12 µg/mL),
        其抗坏血酸当量(17.19、360.80 mg VC/g)高于 50%甲醇提取物(10.67、228.54 mg VC/g)。结论 本研究优化的 NADESs 提取肉苁
        蓉中苯乙醇苷类成分的工艺环保、稳定、可行。

        ABSTRACT    OBJECTIVE To optimize the extraction technology for phenylethanol glycosides from Cistanche deserticola by
        natural deep eutectic solvents (NADESs),and to provide reference for the development and utilization of C. deserticola.
        METHODS The optimal NADESs was selected using total extraction efficiency of echinacoside,acteoside and isoacteoside as
        indexes. Based on single factor test,response surface methodology was used to select the optimal NADESs molar ratio,the optimal
        NADESs water content,the optimal liquid-solid ratio;and the results were optimized by genetic algorithm. Using vitamin C(VC)
        as positive control,the extraction effects of NADESs and traditional solvent (50% methanol) were compared in respects of
        extraction efficiency and antioxidant activities. RESULTS The optimal extraction solution was NADES-11 composed of 1,
        4-butanediol and malonic acid. The optimal extraction technology was as follows as the molar ratio of 1,4-butanediol-malonic acid
        was 1 ∶ 2.5,water content of NADES-11 was 18%,liquid-solid ratio was 30 mL/g,extraction time was 30 min and extraction
        temperature was 30 ℃. The extraction efficiency of NADES-11 was significantly higher than that of 50% methanol(P<0.05). IC50
        values of NADES-11 extract(261.17 and 744.34 µg/mL)to 1,1-diphenyl-2-trinitrophenylhydrazine radical and hydroxyl radical
        were all lower than those of 50% methanol extract(420.97 and 1 175.12 μg/mL). Ascorbic acid equivalent antioxidant capacity of
                                                           NADES-11 extract (17.19 and 360.80 mg VC/g) was higher
