Fig. 3. 1H NMR spectrum showing H-1 and H-3 resonances: (A) Mosher's ester of (1S,4aR,7R,7aS)-nepetalactol, (B) Mosher's ester of (1R,4aS,7S,7aR)-nepetalactol and (C) derivatised air entrainment sample from Dysaphis plantaginea. The oviparae-produced compound is identical to the Mosher's ester of (1R,4aS,7S,7aR)-nepetalactol (B).
