Alkamides from Cissampelos glaberrima.
Two alkamides, deca-2E,4E-dienoic acid isobutylamide (1) and octa-2E,4E-dienoic acid isobutylamide (2), were isolated from the roots of Cissampelos glaberrima (Menispermaceae). Their structures were established by spectral and physical methods. Traces of two new alkamides, decen-2-oic acid isobutylamide (3) and decanoic acid isobutylamide (4), were identified by mass spectrometry.
