TL;DR: The possible effects of trig onelline on health mediated via hypoglycaemic, neuroprotective, anti-cancer, estrogenic, and antibacterial activities are reviewed and potential genetic manipulation of biosynthetic pathways to create trigonelline- and vitamin B3-rich plants and agricultural uses of trigoneLLine-rich genetically modified crops and trees are discussed.

TL;DR: In this article, the anthocyanin determination of a red potato cultivar Kintoki-imo and other colored cultivars grown in Hokkaido, Japan, using DAD-HPLC and ESI-TOF/MS.

TL;DR: Nicotinic acid N-glucoside formation was restricted mostly to ferns and selected orders of angiosperms, whereas other plants produce trigonelline.

TL;DR: The tracer experiments also reveal that significant amounts of these compounds were converted to xanthine, and enter the catabolic pathway via allantoin and allantoic acid, which implies that the salvage pathway is important during the early stages of cell culture in A. thaliana.

TL;DR: In winter, leaves accumulated caffeine but not theobromine, indicating that caffeine is the end product of purine alkaloid synthesis in maté, and the metabolic fate of [8-14C]theobromines, theophylline and xanthine was investigated in the leaf disks of young and mature leaves.
