Sesquiterpenes and Alkaloids from Scorodocarpus borneensis

Abstract A new sesquiterpene, scodopin, and a mixture of three tryptamine-type alkaloids, scorodocarpines A–C, were isolated from the fruits of Scorodocarpus borneensis , together with a known hemisynthetic sesquiterpene, cadalene-β-carboxylic acid, which was isolated from the bark. The structures of the new compounds were elucidated by interpretation of spectral data, especially tandem mass spectrometry for the alkaloid mixture.
