HPLC-DAD-MS/MS ESI characterization of unusual highly glycosylated acylated flavonoids from cauliflower (Brassica oleracea L. var. botrytis) agroindustrial byproducts.
J Agric Food Chem. 2003 Jun 18; 51(13):3895-9.JA

Abstract

In a recent program to investigate the possible use of vegetable handling and commercialization wastes and residues as a source of potentially bioactive extracts, we have studied cauliflower byproducts. A total of twenty-eight compounds were characterized by HPLC-DAD-MS, of these, twenty-two are produced naturally by the plant. The main compounds found were kaempferol 3-diglucoside-7-glucoside and its combinations with different hydroxycinnamic acids. Moreover, some flavonoids with an unusual high grade of glycosylation have been isolated and tentatively identified for the first time. To our knowledge, the characterization of flavonoids with more than four sugars has not been previously reported. The new products isolated were tentatively identified as kaempferol 3-diglucoside-7-diglucoside, kaempferol 3-triglucoside-7-diglucoside, kaempferol 3-feruloyldiglucoside-7-diglucoside, kaempferol 3-sinapoyltriglucoside-7-glucoside, kaempferol 3-disinapoyltriglucoside-7-glucoside, kaempferol 3-sinapoyltriglucoside-7-diglucoside and kaempferol 3-disinapoyltriglucoside-7-diglucoside.
