Supinaionosides A and B: megastigmane glucosides and supinanitrilosides A-F: hydroxynitrile glucosides from the whole plants of Euphorbia supina RAFINESQUE.

From whole plants of Euphorbia supina, two new megastigmane glucosides, named supinaionosides A and B (1, 2), six new hydroxynitrile glucosides, named supinanitrilosides A-F (3-8), and six known compounds were isolated. The structures of the new compounds were elucidated on the basis of spectroscopic and chemical evidence.
