title: Cyanogenesis in Passifloraceae.
abstract: A novel cyclopentenoid cyanogenic bis-glycoside has been isolated from Passiflora capsularis L. Its structure has been tentatively determined as 4-boivinosyl tetraphyllin B. The name passicapsin is proposed for this compound. Linamarin has been isolated from Passiflora warmingii Mast. Extracts of Passiflora perfoliata L. yielded a (probably glycosidic) cyclopentenone dervative, which possibly originated from an unstable glycoside having a free alpha-hydroxynitrile group.
