Abstract
Isolasi kandungan senyawa triterperiold dari daun ArLocarpus eiasticus dilakukan dengan sokletasi menggunakan pelarut n-heksan. Metode pemisahan yang digunakan adalah kromatografi kolom sistem gradien menggunakan pelarut heksan etil asetat dan face padatnya silika gel. Terhadap fraksi ke-3 dilakukan pemurnian dengan metanq diperoleh kristal berwarna putih dengan titik leleh 84-86° C. Dari pengujian spektroskopi UV dan IR didapat bahwa senyawa hasil isolasi mempunyai gugus fungsi OH dan ikatan C=C tak terkonjugasi. Spektroskopi massa menunjukkan pada m/e : 476. Dalam penelitian ini struktur molekul belum dapat ditentukan, perlu dilakukan penelitian le An Isolation of Triterpenoid compound from Artocarpus elasticus leaves was done by soxhlet using n-heksan as a solvent. The separation method applied to was coulomn chromatography with gradien system use solvent n-heksan - etil asetat and the solid fase was silica gel. The third fraction was purified using methanoland white crystalin with melting point of 84-86 C was obtained. From ultra violet and infra merah spectroscopy analysis it can be concluded that the compound resulted from the isolation has functional group of OH and non conjugated C=C bond .Mass spectroscopy resulted in that m/e: 476.In This research, the molecular structure can not be determined, because it still needs further research to be done. bih lanjut.
