Tetraphyllin A, deidaclin, tetraphyllin B and epitetraphyllin B have been isolated from the vegetative parts of Tetrapathaea tetrandra (Passifloraceae), a liana which is native to New Zealand. The fruits of this plant have previously been shown to contain tetraphyllins A and B. This is the first report of the isolation of four cyclopentenoid cyanogenic compounds from a single plant.
