SENYAWA GOLONGAN STEROID DARI DAUN ADAM HAWA (Rhoeo discolor (L,Her.) Hance) DAN UJI SUN PROTECTING FACTOR STEROID COMPOUND FROM ADAM HAWA (Rhoeo discolor (L,Her.) Hance) LEAVES AND SUN PROTECTING FACTOR TEST

The isolation of steroid compounds from Adam Hawa leaves has been carried out through maceration, partition, separation, and purification. relatively pure BF2 isolate was 7 mg amorphous with a melting point 158-1700C. Results 1H-NMR spectrum analysis CDCl3 solvent, 500 MHz δH: 7,53 (d, J= 5,4 Hz, = C-H ); 7,72 5,7 C-H); 5,35 (1H, d, J=5,15 =C-H); 3,51 m, Ar-CH), 0,93 6,2 3H), 0,86 (3H, s), 0,84 0,81 m), 5,2 3H). similar to the ergosterol peroxide ergosterol. So it is predicted that resembled structures those compounds. In vitro sunscreen tests were performed on isolates methanol extracts using UV-Vis spectrometer. SPF values extract at concentrations (ppm) 120, 140, 160 180 respectively 1.913; 1,684; 2252; 2483; also 1,428; 1,655; 2,465; 1883. results showed had weak activity as
