[One new truxillic amide compound from Abrus mollis leaves].

The butanol extract part was extracted and isolated with water, alcohol and different organic solvents from Abrus mollis leaves. 6 compounds were isolated and purified using various column chromatographies and identified with the spectral techniques such as UV, MS, TLC, HPLC and NMR. The structures of 6 compounds were trigonelline (1), praline (2), alanine anhydride (3), (Z)-N-(4-hydroxycinnamoyl)tyrosine (4), (E)-N-(4-hydroxycinnamoyl)tyrosine (5), and abrusamide C (6). Compound 6 is a new compound, and compounds 1-4 were isolated from the plant for the first time.
