Bougenville Flower (Bougainvillae spectabilis Willd) Extract (In Vitro) Activity Test as Sunscreen

Abstract

A research has been conducted on the Sunscreen Activity Test of Bougainvillae spectabilis Willd (Bougainvillae spectabilis Willd) Flower Ethanol Extract. Bougainvillae spectabilis Willd is a shrubby and thorny plant. The flowers are collected into three, belonging to the Nytaginaceae family, which is efficacious as a sunscreen because they contain active compounds such as flavonoids and phenolics, which are polyphenolic compounds. The researchers wanted to know whether or not Bougainvillea spectabilis Willd's ethanolic extract had any anti-inflammatory or sun protection properties, so they measured things like the SPF value, the amount of erythema transmitted (Te%), and the amount of pigmentation transmitted (Tp%). Bougainvillae spectabilis Willd was extracted by maceration for 3 days and remaceration for 2 days using ethanol as the solvent, and the yield percentage was 12.70%. Furthermore, phytochemical screening and an in vitro Sunscreen Activity Test were carried out using the UV-Vis spectrophotometer. The results showed that the ethanolic extract of Bougainvillae spectabilis Willd contained flavonoids, alkaloids, saponins, tannins, and phenolics. Based on the sunscreen activity test, the ethanol extract made in 4 concentrations showed maximum sunscreen activity at SPF values with concentrations of 600 ppm (20,715), 800 ppm (64,367).
