Abstract-Acute and chronic exposure to nonphysiological doses of ultraviolet radiation leads to variety of changes of skin ranging from sun-burn, erythema to skin cancer. For skin protection from deleterious effects of sunlight, sunscreen products are used in various forms having chemical and physical filters. However, synthetic sunscreen formulations are reported to cause adverse effects. Thus the present study was planned to evaluate the sun protection factor (SPF) of leaves extract of Murraya koenigii for their application as herbal sunscreens. The results suggested that the occurrence of active compounds responsible for ultraviolet absorption can be extracted for use in sunscreens preparations as better, cheaper and safe alternative to harmful chemical sunscreens.

The ultimate aim of this study was to evaluate antioxidant activities using DPPH and ABTS assay and antioxidant substances of Melientha suavis Pierre (Melientha) extracts with ethanol (EtOH) and subsequent partition with hexane, dichloromethane (CH2Cl2), ethyl acetate (EtOAc) and distilled water (W). The Melientha extract was assessed the sunscreen activities by sun protection factor which was compared with octyldimethyl PABA. Additionally, the stability test of Melientha extracts added in the cosmetic base-formula was investigated. The sun protection substances of Melientha extracts were determined by GC-MS analysis. Among the extract and fractions, the ethanolic extract showed the highest activities. The IC50 of Melientha extract to free radical scavenging determined by DPPH assay and ABTS assay were 53.20 ± 7.37 μg/ml and 64.17 ± 5.76 μg/ml, respectively. The total phenolic compound of ethanol extract was 149.87 ± 2.72 mg GE/g of ext and total flavonoid content was 51.60 ± 4.12 mg CE/g of ext. The sun protection factor (SPF) of ethanol extract was 26.61 ± 0.10. Cinamate and its derivative which were claim as sunscreen substance was found by GC-MS analysis of Melientha ethanol extract.
