Five cyanohydrin glycosides with a cyclopentene ring, tetraphyllin A, tetraphyllin B, tetraphyllin B sulphate, deidaclin and volkenin, were isolated from Passiflora foetida grown from seeds collected on the Galápagos Islands. By contrast, P. foetida collected on Réunion Island contained the valine-derived glycoside linamarin, along with the cyclopentanoids tetraphyllin B, volkenin and tetraphyllin B sulphate. The chemical differences between the two populations were accompanied by pronounced morphological differences. This is the first report of two populations of the same species, having different patterns of cyclopentanoid and valine-derived glycosides. Two populations of Passiflora foetida were found to have different pattern of cyclopentanoid and valine-derived glycosides, and to be morphologically different.
