TRITERPENOID JENIS LUPANA DARI FRAKSI ETIL ASETAT KULIT BATANG Calophyllum pulcherrimum WALL
The triterpenoid compound had been isolated from ethyl acetate fraction from bark of Calophyllum pulcherrimum Wall. Extraction was done with partition method using ethyl acetate and resulted compound was separated using chromatography technique. Compound isolation resulted 0.06 g white crystal, with melting point 213-215 °C. UV spectrum showed maximum absorption at X,max 290 nm (7t->n* trantition) from (-C=C-) and Xmax 342 nm (n—m*) from (-C=0). IR spectrum showed characteristic absorption at wave number omax (cm'1) at 3328.9 cm'1 (OH functional group), 2945.1-2856.4 cm'1 (aliphatic C-H) 1737.7 cm-1 (C=0 functional group), 1637.5 cm'1 (carboxy!ate C-O), 1379.0 cm'1 (gem dimetil), 1041.5 cm'1 (alcohol -C-O). LCMS showed one signal at retention time (T = 3.9 minutes). 'H-NMR spectrum seen existence six signal with 3H integration at 8h 0.75; 0.82; 0.94; 0.96;1.02; and 1.67 ppm and metilen proton (vinilik) at 8h 4.68 ppm (IH, d) and 4.56 ppm (IH, d), furthermore proton signal at 8h 3.18 ppm (IH, t) be individuality from sketch base triterpen cluster that OH. 13C-NMR found three signal 8c 173.7 ppm carbonil signal (-C=0), 151.2 and 109.5 ppm signal (-C=C-), at 8c 79.2 ppm cluster that (-CH-OH), compotmd isolation result be triterpenoid compound kind lupana with molecule formula C3oH4g03.
