Abstract


The Objective of this research to isolate and identificate phenolic compounds from the stem bark of Erythrina fusca L. and determining sunscreen activity, yielded pterocarpan compound, sandwicensin. This compound isolated and purificated by various chromatographic techniques, such as liquid vacuum chromatography, flach column chromatography, and radial chromatography. Structure of sandwicensin was elucidated based on spectrophotometric method such as UV, IR, HR-ESIMS, 1H and 13C NMR also 2D NMR (HMQC and HMBC). Sunscreen activity of sandwicensin obtained by calculating % T eritema and % T pigmented from the UV Spectrophotometre showing a sunscreen activity.

Keywords:  Flavonoid compound, Sanwisensin, Erythrina fusca L., Sunscreen
