Abstract
From the fruit of Kigelia africana three fractions of secondary metabolites were isolated. Fraction 1 (CD-1) was characterized by using UV-Vis, FTIR, 1D and 2D NMR and MS, meanwhile fraction 2 (CD-2) and 3 (B-1) were characterized by LCMS and compared with literature. All these fractions were screened for anticancer activity by using (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) method to calculate IC50 toward Michigan Cancer Foundation-7 MCF-7 breast cancer and menogaril-resistant mouse leukemia P388 cells. Based on spectroscopic data, CD-1 fraction was identified as methyl ferulate (1). On the other hand, the B-1 and CD-2 fraction did not pure, yet. Based on LCMS data that analyzed by chemspider and masslink software, CD-2 fraction was estimated as compound mixture with dominant compounds like viscumside (2), specioside (3), caffeic acid glucoside (4), ferulic acid (5), meanwhile B-1 fraction was estimated as compound mixture with dominant warfarin alcohol (6), p-Coumaroyl glucose (7) and β - Sitosterol (8) compounds. Nevertheless, all isolated fractions did not show anticancer activity towards both the cancer cells since it had different constituent compared with previous results.
