Structural elucidation of limonoids and steroids from Trichilia connaroides.
Six limonoids, trijugins D-H (1-5) and methyl 8alpha-hydroxy-8,30-dihydroangolensate (6), two degraded limonoids, trichiconnarins A and B (7-8), and a pregnane steroid, 3beta,4alpha-dihydroxypregnan-21-one (9), along with the known trijugin C (10) and 3beta,4alpha-dihydroxypregnan-16-one (11) were isolated from twigs and leaves of Trichilia connaroides. Their structures were established on the basis of extensive spectroscopic analysis.
