Abstract From the EtOAc extract of the latex of Jatropha pohliana (Euphorbiaceae), two cyclic heptapeptides, pohlianins A ( 1 ) and B ( 2 ) and one cyclic octapeptide, pohlianin C ( 3 ) were isolated by a multi-step chromatography procedure, including HPLC. Their structure were elucidated by chemical degradation, mass spectrometry, homonuclear and heteronuclear NMR experiments. Conformational analysis of these peptides was made by using NMR experiments and distance geometry calculations. Their… CONTINUE READING
