Specialty Dihydrobenzoxanthone’s Artocarpus Purified By Vacuum Liquid Chromatography (VLC)

Abstract

One family of plants that are source of bioactive chemicals is the Moraceae. Artocarpus is t he main genus of the Moraceae . Several species of the genus Artocarpus have been isolated their secondary metabolites . The main fractions obtained from the VLC are analyzed again by TLC. Fractions that have same spots (Rf) pooled. Purification process on main factions are done repeatedly by radial chromatography . Flavonoid is the most found from Artocarpus plant . D ihydrobenzoxanthone is one of flavonoid derivatives which is successfully isolated from Artocarpus . D ihydrobenzoxanthone is only formed from the flavone with ring B which is oxygenated with pattern of 2 , 4 and 5 . Students can be learned d ihydrobenzoxanthone’s Artocarpus by laboratory activities.
