To analyze the ultraviolet-screening of the n-butanol extracts of mangosteen pericarp and alpha-mangostin, compare the ultraviolet-screening effect of the extracts with rutin and ultramicro-titanium dioxide (TiO2).
The samples (n-butanol extract from mangosteen pericarp, alpha-mangostin, rutin and TiO2) were scanned at different wavelength and Pan-wavelength by ultraviolet spectrophotometry.
The n-butanol extracts and alpha-mangostin had relatively satisfactory effects on ultraviolet-screening when the concentration was over 0.40 mg/ml and the effects on ultraviolet-screening was better than TiO2.
The n-butanol extracts and alpha-mangostin had a positive ultraviolet-screening activity which was better than TiO2.
分析山竹果皮正丁醇提取物及α-倒捻子素的紫外线屏蔽作用，比较提取物与芦丁及超微二氧化钛（TiO₂）的紫外线屏蔽效果。
采用紫外分光光度法对样品（山竹果皮正丁醇提取物、α-倒捻子素、芦丁和TiO₂）在不同波长及全波长下进行扫描。
当浓度超过0.40mg/ml时，正丁醇提取物和α-倒捻子素具有相对满意的紫外线屏蔽效果，且其紫外线屏蔽效果优于TiO₂。
正丁醇提取物和α-倒捻子素具有积极的紫外线屏蔽活性，且优于TiO₂。
