A biologically monitored fractionation of the methanolic extracts of the root and fruits of Kigelia pinnata D.C. led to the isolation of the naphthoquinones kigelinone (1), isopinnatal (2), dehydro-alpha-lapachone (3), and lapachol (4) and the phenylpropanoids p-coumaric acid (5) and ferulic acid (6) as the compounds responsible for the observed antibacterial and antifungal activity of the root and kigelinone (1) and caffeic acid (7) from the fruits of this plant.
3b, 19a-dihydroxyurs-12-ene-28oic acid, caffeic acid, and chlorgenic were isolated from the fruits and 3b, 19a-hydroxyurs-12-ene-28-oic acid, ferulic acid and p-coumaric acid from the roots of Kigelia pinnata. Key Words: Kigelia pinnata, Bignoniaceae, Triterpenoids, Phenolic acids Nig. J. Nat. Prod. And Med. Vol.1 1997: 40-41
