Abstract

Dalam rangka penyelidikan kandungan kimia tumbuh tumbuhan famili moraceae asal Indonesia, telah dilakukan isolasi senyawa-senyawa yang terkandung dalam ekstrak kloroform daun Artocarpus elasticus Reinw (Bendo) yang merupakan salah satu spesies famili moraceae yang diambil dari daerah Tusam Banyumanik Semarang. Penisahan dilakukan dengan kromatografi kolom vakum sistem gradien menggunakan pelarut n-heksana dan etil asetat dengan fase padatnya silika gel. Dihasilkan senyawa padat masing-masing senyawa I dan senyawa II. Analisis struktur dengan MS,IR dan UV serta melalui pendekatan kemotaksonomi disarankan struktur senyawa I adalah 0-sitosterol, sedang struktur senyawa II beluin dapat ditentukan namun hasil analisis data IR menunjukkan bahwa senyawa II adalah triterpenoid yang termasuk golongan asam. In behalf research of chemical compounds content in the Indonesian Moraceae plants the isolation compounds of chloroform extract from Artocarpus elasticus Reinw leaves taken from Tusam, Banyumanik, Semarang has been done. The separation was applied to vacum column chromatography with gradien system using solvent of n-hexane and ethyl acetate with the solid phase of silica gel. The research was resulted two solid compounds, they are compound I and II. The result of MS, IR and UV analysis and through chemotaxonomy approach, the structure compound I was proposed (3-sitosterol and the structure of the compound II hadn't been determined nevertheless the result of IR spectroscopy analysis, it was a triterpenoid of acid group. . • This document is Undip Institutidnal Repository Collection.
