Abstract
Four novel yellowish pigments, uroleuconaphins A2a, A2b (3a, 3b), and B2a, B2b (4a, 4b), were isolated from the aphid Uroleucon nigrotuberculatum (Olive). Their structures were established by detailed analyses of 1D and 2D NMR spectra and mechanistic consideration of the interconversion between 3 (or 4) and uroleuconaphin A1 (1) (or B1 (2)).
