This work was aimed at isolating and characterizing some bioactive constituent(s) from the stem bark of Ficus abutilifolia. The phytochemical analysis of the crude methanol extract indicates the presence of flavonoids, alkaloids, cardiac glycosides, saponnins, tannin, steroids and triterpenes. The extract was subjected to column chromatography which resulted in the isolation and purification of a white needle-like crystalline substance with a melting point of 134 -136 0 C, the 13 CNMR shows
