Abstract
Telah dilakukan isolasi terhadap kandungan senyawa triterpenoid di dalam bunga Artocarpus communis ( Familia : Moraceae ) Isolasi dilakukan dengan ekstraksi soklet mengciunakan pelarut k1orc3form Pemurnian selanjutnya dilakukan dengan kromatografi kolom, sebagai.adsorben dipakai silika gel • dan sebagai eluent adalah kloroform, dan dilanjutkan dengan rekristalisasi menggunakan pelarut eter, dioperoLeh kristal sisik berwarna putih dengan titik leleh 990--100 C. Dengan melakukan pendekatan kemotaksonomi dan dengan pengujian spektroskopi IR, UV, NMR dan Massa serta perbandingan data literatur menunjukkan bahwa senyawa hasil isolasi cnerupakan senyawa Sikloartenil asetat ( kelompok triterpenoid ). It has been done isolation of containing triterpenoid compound in flower Artocarpus Communis (Familia:Moraceae). Isolation was done by soxlet extraction with chloroform as solvent. The next purification of extraction by coulomn chromatography with silica gel as an adsorben and chloroform as an eluent, followed by recrxstaliaation with eter and gave a herb cristal with m.p. 99 --100 C. By chemotaxonomy approach, and in comparation with literature data and by examination spectroscopy IR, UV, NR and Massa, the compound as the result of isolation is Cycloartenyl acetate ( triterpenoid group )
