Extraction of flavonoids from flavonoid-rich parts in tartary buckwheat and identification of the main flavonoids
In order to make full use of tartary buckwheat, a new method separating flavonoid-rich parts from entire kernels and a new process of extracting and purifying flavonoids from these flavonoid-rich parts were introduced. By ultraviolet-visible spectrometry (UV) and electrospray ionized mass spectrometry (ESI-MS), the main flavonoid in the last product was identified as rutin. (c) 2005 Elsevier Ltd.
