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.
