- Extraction, isolation and identification of alkaloid from bandotan’s leaf (Ageratum conyzoides Linn.) has been carried out. Extraction was done by maceration method by using methanol. Isolation has been carried out by adding acid base to give crude alkaloid. The isolation followed by column chromatography by using chloroform-methanol-amonia as mobile phase (85-15-1) and silica gel 60 (mesh 70-230 ASTM) as statis phase. The result of column chromatography has get one white crystal alkaloid shaped as needle (Rf 0,62). From ultraviolet spectrophotometry has showed maximum absorbtion at 246,6 nm, 276,4 nm and 284,4 nm. From infra red spectrophotometry showed OH, C=O, C-O, C-H of CH2 and C-H of CH3.
