The regenerated plants obtained from Strophanthus divaricatus calli co
ntain 10 cardenolides, accumulating seven of them in the original plan
ts. At the same time, two new cardenolides were isolated and structura
lly elucidated as 17betaH-divostroside and 17betaH-divaricoside by spe
ctrometry. Cardenolide production with morphological differentiation w
as demonstrated in Strophanthus species.
