title: [Study on ultraviolet-screening effect of extracts from mangosteen (Garcinia mangostana Linn.) pericarp].
abstract: OBJECTIVE
  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).
  
  
  METHODS
  The samples (n-butanol extract from mangosteen pericarp, alpha-mangostin, rutin and TiO2) were scanned at different wavelength and Pan-wavelength by ultraviolet spectrophotometry.
  
  
  RESULTS
  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.
  
  
  CONCLUSIONS
  The n-butanol extracts and alpha-mangostin had a positive ultraviolet-screening activity which was better than TiO2.
