Kelor plant (Moringa oleifera Lamk) is a plant that grows naturally in a tropical climate. During this decoction of pirdot leaves plants are used by the people as antimicroba. The purpose of this study was to isolate triterpenoid compound from ethyl acetate extract of kelor leaves. The sample extraction was performed by maceration method using methanol as a solvent. Fractionation used n-hexana and etil asetat as a solvent. The separation and purification of the compound was carried out by column chromatography method followed by stain pattern analysis with thin layer chromatography (TLC). Characterization and elucidation of pure compound structures using UV, IR, 1H-NMR, 12C-NMR, HSQC, HMBC, and 1H-1H COSY, and compared with various literatures. Based on the result of structural elusidation, the pure isolate obtained is a pentacyclic triterpenoid group compound with the molecular formula C30H50O and the name of 3-hydroxy, 20 (29) -en, lupenol. The triterpenoid compound of 3-hidroxy, 20 (29) -en, lupenol is the first isolated and reported from leaves of kelor plant.

Terbium-161 (161Tb) is a potential radiolanthanide due to its favorable properties for treatment small size of cancer. Preliminary study on radiochemical separation of 161Tb from Gd/Tb matrix using Ln resin column based on extraction chromatography method has been carried out. 161Tb radionuclide was produced by irradiation of natural Gd2O3 target through neutron thermal bombardment at G.A. Siwabessy Multipurpose Reactor. Fractions eluted from the column containing Gd/Tb matrix of irradiated natural Gd2O3 target were identified and quantified using a γ-rays spectrometer with HP-Ge detector coupled to a multichannel analyzer. The results show that the optimum condition on 161Tb separation from irradiated Gd2O3 target with radionuclide purity 99.27 ± 0.30% was obtained using HNO3 solution with concentration of 0.8 and 3 N to separate gadolinium and terbium isotope, respectively. The yield of 161Tb obtained from the separation was 61.21 ± 2.05% and Gd recovered was 97.15 ± 2.23%. Based on this experiment, 161Tb has been separated from irradiated natural gadolinium oxide target with high radionuclide purity.
