Abstract: UV absorption performance,light stability and pH stability of chlorogenic acid in Flos lonicerae as well as sunscreen performance of its formulated product were investigated.Results showed that UV absorption spectrum of the Flos lonicerae extract ranges between 280~350 nm,with good UV absorbing performance.Chlorogenic acid has photochemical activity that results in photodegradation reaction.Retention ratio of the chlorogenic acid in the Flos lonicerae extract solution decreases as the irradiation time increases,with a retention ratio of 85.6% after an irradiation time of 8 h.The chlorogenic acid is rather stable when pH is a range of 3~7.Vitro evaluation for SPF of sunscreen cream formulated with Flos lonicerae extract depends on content of chlorogenic acid in the extract.As the mass fraction of chlorogenic acid in the extract achieves 2.15%,SPF of sunscreen cream formulated with the extract achieves 15.
