Analysis of the polar extracts from kancolla seeds led to the isolation of five betaines: glycine betaine, trigonelline, trigonelline methylester, trigonelline glucosylester and 3-carboxy-1-(2-sulfoethyl)-pyridinium, the last two of which have not previously been reported in the literature. All structures were elucidated from spectroscopic [NMR (1H, 13C, COSY, HOHAHA, HMQC, HMBC)] and mass spectrometric data (ESI-MS).

Abstract
Analysis of the polar extracts from kancolla seeds led to the isolation of five betaines: glycine betaine, trigonelline, trigonelline methylester, trigonelline glucosylester and 3-carboxy-1-(2-sulfoethyl)-pyridinium, the last two of which have not previously been reported in the literature. All structures were elucidated from spectroscopic [NMR (1H, 13C, COSY, HOHAHA, HMQC, HMBC)] and mass spectrometric data (ESI-MS).| File | Dimensione | Formato | |
