Sunlight consists of ultraviolet (UV) light and based on its wavelength, the UV light could be categorized into UVA, UVB, and UVC. UVA has the longest wavelength of 320-400 nm and causes skin cancer in the epidermal layer. On the other hand, UVB with a wavelength of 290-320 nm gives an effect on the epidermis and dermis layer causing the skin to burn. Organic Ultraviolet (UV) filters can be found in plants and fruits which have orange-red or pink colours, such as watermelon, tomato, secang (Caesalpinia sappan), carrot, dragon fruit, faloak (Sterculia quadrifida R.Br), strawberry, papaya, and rosella. Most of these plants contain active compounds such as carotenoids and anthocyanin. Determination of the effectiveness of the extracts as potential sunscreen was carried out by determining the Sun Protecting Factor (SPF) value in vitro by UV spectrophotometry. Maceration technique was used for the extraction process by using ethanol with a ratio of 4:1. Each of dried extract (100 mg) was then mixed well in the ethanol (96%, 50 mL) until all the extract was dissolved and then filtered. The absorbance of each extract was measured in the wavelength range of 290-320 nm and the interval was set at 5 nm. The SPF values were determined by the Equation of Mansur. It was observed that all of the red pigmented extracts showed UV protection capabilities, with secang extract gave the highest SPF value of 18.490. Therefore, the secang extract would have good potential to be developed as one of the ingredients in the sunscreen cream. Sunscreen cream combination between secang extract and ZnO showed good quality and significant SPF value than ZnO and extract secang sunscreen cream.
