Quantitative analysis of trigonelline in some Annona species by proton NMR spectroscopy

A quantitative (1)H NMR method (qHNMR) was used to measure the trigonelline content in the leaves of six species of the Annona genus. The methodology employed compared the intensities of the signals at δ 9.14 (H-2) and δ 0.00, the internal standard TSP-d(4). This measuring method was able to establi...

Sumario:A quantitative (1)H NMR method (qHNMR) was used to measure the trigonelline content in the leaves of six species of the Annona genus. The methodology employed compared the intensities of the signals at δ 9.14 (H-2) and δ 0.00, the internal standard TSP-d(4). This measuring method was able to establish the concentration of trigonelline in the range from 0.67 to 10.04 mg·g(−1) depending on the investigated extract. [Image: see text]
