Abstract
Dalam rangka pemanfaatan dan pendataan potensi sumber daya alam hayati, dilakukan eksplorasi dan identifikasi senyawa-senyawa kimia bahan alam yang terkandung dalam tumbuhan. Sebagai langkah awal dilakukan isolasi senyawa-senyawa yang terkandung dalam ekstrak kloroform kulit batang Artocarpus communis Forst (kluweh). Pemisahan dilakukan dengan kromatografi kolom vakum dan kromatografi lapis tipis preparatif pada fasa diam silika gel. Dihasilkan tiga senyawa padat masing-masing senyawa I, II dan III. Analisis struktur dengan MS, IR dan UV serta melalui pendekatan kemotaksonomi disarankan struktur senyawa I adalah sikloartenil asetat. Sedang struktur senyawa II dan III belum dapat ditentukan, namun hasil analisis data IR menuniukkan bahwa keduanya mempunyai gugus fungsl ester. In behalf the use and data collection of the potention plant of natural resources, was done exploration and identification of natural material of chemical compounds that were found in plants. As first step, compounds that were found in chloroform extract from tree bark of Artocarpus coomunis Forst had been isolated. The separation was done by vacum column chromatography and preparative thin layer chromatography with stationary phase of silica gel. The research was resulted three solid compounds, I, II and III. The result of MS IR and UV analysis and through chemotaxonomy approach, the structure compound I is cycloartenyl acetate was porposed. The structure of compounds II and III hadn't been determined. Nevertheless the result of IR spectroscopy analysis, they have ester fungsional group.
