11/10/2015· Trigonelline (3-carboxy-1-methyl pyridinium) was identified as a relevant bioactivity and taste imparting component in Balanites aegyptiaca fruit, using 1 H NMR of crude extracts without any fractionation or isolation step. The structural integrity of trigonelline was established within the extract matrix via 1 H NMR, 1 H– 1 H COSY, HMQC and HMBC and by comparison with authentic standard.
