若干种防晒水果提取液的紫外吸收光谱测定

Determination of Several Sunscreen Fruit Extracts by UV Absorption Spectroscopy

选取番茄、猕猴桃、苹果(糖心)、石榴、柑橘、油桃、草莓、柠檬8种水果,通过研磨过滤提取有效防晒成分,利用紫外分光光度计分别测定各种提取液的紫外吸收光谱,将各种提取液的最大吸收峰及吸光度从3种(UVA、UVB、UVC)紫外线波长范围进行分析。结果表明,不同的水果提取液紫外均有一定的吸收,而且紫外光存在一定的差异。

This paper selected eight kinds of fruits such as cherry tomatoes, kiwifruit, apples(candy heart), pomegranates, citrus fruits, peaches and strawberries. The effective sunscreen components were extracted by grinding and filtering and the spectrophotometer was used. The ultraviolet absorption spectra of various extracts were measured, and the maximum absorption peaks and absorbances of various extracts were analyzed from the three ultraviolet (UVA, UVB, UVC) ultraviolet wavelength ranges. The result showed that different fruit extracts had a certain absorption of ultraviolet, but there were a certain difference in the absorption of ultraviolet light.
