摘要：

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 (H-1, C-13, COSY, HOHAHA, HMQC, HMBC)] and mass spectrometric data (ESI-MS). (c) 2005 Elsevier Ltd. All rights reserved.
