Khayalactone, a novel limonoid from Khaya grandifoliola
Tetrahedron Letters, 1998Abstract The isolation and structure elucidation by spectroscopic methods of khayalactone (1) from extracts of Khaya grandifoliola is described. Khayalactone is a novel hexacyclic A,B,D-seco limonoid with a highly oxidised carbon framework.

In vitro antimalarial activity of limonoids from Khaya grandifoliola C.D.C. (Meliaceae)
Journal of Ethnopharmacology, 2000The crude extract from the bark and seeds of Khaya grandifoliola was active in vitro against Plasmodium falciparum with an IC50 value of 13.23 microg/ml. The extract was purified to obtain seven limonoids--methylangolensate (1), 6-methylhydroxyangolensate (2), gedunin (3), 7-deacetylkhivorin (5), 1-deacetylkhivorin (6), swietenolide (7), 6 ...

Limonoids from the stem bark of Khaya grandifoliola
Phytochemistry, 2008Three limonoids, deacetylkhayanolide E (1), 6S-hydroxykhayalactone (2), and grandifolide A (3), along with three known ones, were isolated from stem bark of the Nigerian medicinal plant Khaya grandifoliola. Their structures were characterized on the basis of the application of spectroscopic methods.

Introduction: In recent years, plant-mediated synthesis of silver nanoparticles has evolved as a promising alternative to traditional synthesis methods. In addition to producing silver nanoparticles with diverse biomedical potential, the biosynthesis approach is known to be inexpensive, rapid, and environmentally friendly.

Properties of Khaya grandifoliola gum
Journal of the Science of Food and Agriculture, 1978AbstractThe gum exudate of Khaya grandifoliola has only limited solubility in water. Analysis of the gum showed that approximately 50% was in the free acid form and the remainder was largely the calcium salt. The gum dissolves in sodium carbonate solution with removal of calcium ions.

Effects of Khaya grandifoliola (Meliaceae) on some biochemical parameters in rats
Journal of Ethnopharmacology, 2005The antimalarial activity of the crude water extract of Khaya grandifoliola (Welw) CDC (Meliaceae) stem bark in mice has been reported. The biochemical effects of the crude water extract at doses of 100, 200 and 500 mg/day were examine in plasma, liver, and heart after 7 and 21 days of administration and after a recovery period of 21 days.
