| 中文摘要: |
| 采用超声辅助提取法从牛大力中提取防晒成分，以单因素实验及正交实验考察防晒成
分的最佳提取工艺条件，并且研究了提取液中防晒成分的稳定性。结果表明：以无水乙醇为溶剂，
料液比为20∶25（mg/mL），提取温度60 ℃，提取时间90 min、超声功率144 W的条件下牛大力中防
晒成分提取效果较佳，温度、光照和放置时间对提取液的防晒活性没有明显的影响。牛大力中含
有较强的紫外线吸收成分，主要吸收波长在280～320 nm 之间，具有开发为天然防晒剂的潜力。 |
| 英文摘要: |
| The sunscreen component was extracted from Millettia speciosa by using the ultrasonic-assisted extraction
method, and the optimum condition of extraction was confirmed by means of single factor experiments and orthogonal exper⁃
iment. The stability of the sunscreen component from the extraction was also investigated. The results indicated that under
the extraction condition in which anhydrous ethanol was used as the solvent, the solid-liquidratio was 20:25 (mg/mL), the
temperature of extraction was 60 ℃, extraction time was 90 min and the ultrasonic power was 144W, the sunscreen compo⁃
nent from Millettia speciosa can be extracted preferably, the results of experiments also revealed that temperature, light and
storage time did not have obvious effect on the activity of the sunscreen component. Therefore, Millettia speciosa contains
the component absorbing ultraviolet strongly, the main absorption wavelength is between 280~320 nm, and this plant has
the potential to be developed as a natural sunscreen. |
