Abstract

Sebagai usaba untuk menggali amber daya alam nabati, terutama dari gudut metabolit sekunder, telah dilakukan penelitian terftsdap Artocarpus elasticus, suatu tanaman khas Indonesia yang keberadaannya raasih jarang. Penelitian ini dilakukan untuk mengisolasi senyawa-senyawa dalam ekstrak klorofonn kulit batang species tersebut. Peraisahan dilakukan dengan kromatografi kolom dan kromatografi kolom vakum, berfasa diam silika gel. Setelah melalui proses pemurnian, berhasil diperoleh 2 senyawa, yaitu senyawa T dan senyawa Berdasarkan basil analisis terbadap senyawa basil isolasi dan melalui pendekatan khemotaksonomi, diusulkan bahwa senyawa I merupakan golongan triteipenoid dengan gugus ester. Senyawa II merupakan suatu glikosida, yang setelah melalui hidrolisis dengan a.sam klorida, berhasil dipisahkan antara gula dan aglikon. Analisis lebih lanjut me;nunjukkan bahwa jenis gula yang terikat adalah xilosa, sedangkan aglikonnya memberi basil positif terbadap uji golongan triteipenoid. In an effort to explore the plant potention of natural resources, especially from secondary metabolism's corner, there had been done an investigation to Artocarpus elasticus, which is rare species endemic in Indonesia. The research was done to isolate some chemical constituents in chloroform extract from tree bark of this species. The coloumn chromatography and the vacuum colour= chromatography were choosen as separation methods, using silica gel as a stationary phase. After purifying process, two compounds, compound I and II respectively could be isolated. Base on the chemical analysis of these compounds and through chemotaxonomy approach, the first compound was proposed as triterpene with esther group. The second compound was identified as a glycoside, but it was succesfully to be separated between sugar and aglicone by hydrolysis using chloride acid. Further analysis showed that the sugar bonded at the second compound was xylose, while the aglicone gave positive test on triterpene analysis.
