摘要: 研究木棉花黄酮的提取工艺并评价其祛痘功效。以广东肇庆木棉花为原料,经过超声辅助醇提后,考察筛选最适大孔树脂类型并确定木棉花黄酮粗提物的纯化工艺,采用体外抑菌圈实验方法测定纯化精制的木棉花黄酮对表皮葡萄球菌和痤疮丙酸杆菌的抑制效果;采用体外美白活性方法测定木棉花黄酮对酪氨酸酶的抑制率,并通过斑马鱼胚胎黑色素抑制测试法对木棉花黄酮的美白活性进行进一步验证;最后采用体外抗氧化活性测定方法考察木棉花黄酮对ABTS?+和DPPH等自由基的清除能力。通过对比8种大孔树脂对木棉花黄酮的吸附率和解析率,筛选出D101为最佳树脂类型,同时考察得出其最佳的静态吸附-解析条件为:吸附时间6 h,解析时间4 h,解析液的乙醇浓度为60%;其最佳的动态吸附-解析条件为:上样体积2 BV,解析液洗脱体积0.625 BV。纯化后木棉花黄酮的纯度由32.5%提高至98.2%。精制的木棉花黄酮对ABTS?+和DPPH自由基清除率的IC50值分别为0.62±0.011 mg/mL和11.8±0.624 μg/mL。木棉花黄酮对酪氨酸酶抑制率的IC50为1.69±0.002 mg/mL。木棉花黄酮浓度在1.0 mg/mL时对斑马鱼胚胎黑色素抑制率为12%,具有显著的美白活性。通过抑菌圈试验可得木棉花黄酮浓度为12.5 mg/mL时,对痤疮丙酸杆菌表现为中敏,对表皮葡萄球菌表现为高敏,且此抑菌效果呈现剂量依赖效应。综上,本研究纯化制备的木棉花黄酮具有美白、抗氧化、抑菌祛痘等多重护肤活性,具有良好的祛痘产品应用与开发价值。

Abstract: Study the extraction process of kapok flavonoids and evaluate its anti-acne efficacy. Using Guangdong Zhaoqing kapok as raw material, after ultrasonic-assisted alcohol extraction, the most suitable macroporous resin type was investigated and the purification process of the crude kapok flavonoids was determined. The in vitro inhibition zone experiment method was used to determine the purified and refined kapok flavonoids. The inhibitory effect of Staphylococcus epidermidis and Propionibacterium acnes; the in vitro whitening activity method was used to determine the inhibition rate of kapok flavonoids on tyrosinase, and the whitening activity of kapok flavonoids was further verified by the zebrafish embryo melanin inhibition test; Finally, the in vitro antioxidant activity determination method was used to investigate the scavenging ability of kapok flavonoids on free radicals such as ABTS?+ and DPPH. By comparing the adsorption rate and resolution rate of 8 kinds of macroporous resins to kapok flavonoids, D101 was screened out as the best resin type, and the best static adsorption desorption conditions were investigated as follows: adsorption time 6 h,resolution time 4 h, the ethanol concentration of the analytical solution is 60%; the best dynamic adsorption analysis conditions are: loading volume 2 BV, analytical solution elution volume 0.625 BV. After purification, the purity of kapok flavonoids increased from 32.5% to 98.2%. The IC50 values of the purified kapok flavonoids on ABTS?+ and DPPH free radical scavenging rates were 0.62±0.011 mg/mL and 11.8±0.624 μg/mL, respectively.The IC50 of the inhibition rate of Kapok flavonoids on tyrosinase is 1.69±0.002 mg/mL. When the concentration of kapok flavonoids was 1.0 mg/mL, the inhibition rate of melanin in zebrafish embryos was 12%, and it had significant whitening activity.Through the inhibition zone test, when the concentration of kapok flavonoids is 12.5 mg/mL, it is moderately sensitive to Propionibacterium acnes and highly sensitive to Staphylococcus epidermidis, and this antibacterial effect presents a dose-dependent effect.In summary, the kapok flavonoids purified and prepared in this study have multiple skin care activities such as whitening, antioxidation, antibacterial and anti-acne, and have good application and development value for anti-acne products.
