title: Quassinoids from Ailanthus excelsa.
abstract: Three quassinoids, 1, 2 and 3, 4-dihydro excelsin 3 were isolated from the stem bark of Ailanthus excelsa, along with five known quassinoids excelsin, glaucarubine, ailanthinone, glaucarubinone and glaucarubolone. The glaucarubolone has been isolated for the first time from this plant. The structural elucidation is based on the analysis of spectroscopic data.
