摘要

Polyol solvents were used to extract Camellia oleifera Abel dregs and sunscreen properties of the extracts were examined in the present paper. The effects of extracts obtained with water and ethanol were compared. This study found that polyols were more efficient at extracting flavonoid glycosides, triterpenoid glycosides, and other polyphenols in the C. oleifera Abel dregs, resulting in a more efficient sunscreen. The polyphenols in the extract had peak absorbance at wavelengths of 254, 280, and 329 nm, the triterpenoid glycosides had a peak at 200-240 nm and the flavonoid glycosides showed a broad range of absorption (at 230-400 nm). The extract obtained with polyol solvent had strong absorption at wavelengths of 200-400 nm. The interaction of the polyol extracts with organic UV-absorbers or inorganic sunscreen agents showed synergic effects and the extract can significantly improve the sunscreen effect of organic UV-absorbers or inorganic sunscreen agents. Therefore, this extract can decrease the amount of organic UV-absorbers and inorganic sunscreen agents used and can increase protection against UVA and UVB. It can be used in maintenance and sunscreen products.

Oleifera abel渣中的其他多酚更有效，导致更有效的防晒剂。提取物中的多酚在254,280和329nm的波长下具有峰值吸光度，三萜糖苷在200-240nm处具有峰，并且黄酮苷糖苷显示出广泛的吸收（在230-400nm处）。用多元醇溶剂获得的提取物在200-400nm的波长下具有很强的吸收。多元醇提取物与有机紫外线吸收剂或无机防晒剂的相互作用表现出协同作用，提取物可以显着改善有机紫外线吸收剂或无机防晒剂的防晒效果。因此，该提取物可以减少有机紫外线吸收剂和无机防晒剂的量，并且可以增加对UVA和UVB的保护。它可用于维护和防晒产品。
