title: Three new limonoids from Cipadessa cinerascens.
abstract: Three new limonoids, cipadesins D--F (1--3), together with 8,15-dihydroxy-13E-labdane, beta-sitosterol and beta-daucosterol, were isolated from the leaves and bark of Cipadessa cinerascens. Their structures were elucidated by spectral evidence. X-Ray crystallographic analysis confirmed the structure of 1.
