Phenolic compounds in external leaves of tronchuda cabbage (Brassica oleracea L. var. costata DC).
J Agric Food Chem. 2005 Apr 20; 53(8):2901-7.JA

Abstract

Glycosylated kaempferol derivatives from the external leaves of tronchuda cabbage (Brassica oleracea L. var. costata DC) characterized by reversed-phase HPLC-DAD-MS/MS-ESI were kaempferol 3-O-sophorotrioside-7-O-glucoside, kaempferol 3-O- (methoxycaffeoyl/caffeoyl)sophoroside-7-O-glucoside, kaempferol 3-O-sophoroside-7-O-glucoside, kaempferol 3-O-sophorotrioside-7-O-sophoroside, kaempferol 3-O-sophoroside-7-O-sophoroside, kaempferol 3-O-tetraglucoside-7-O-sophoroside, kaempferol 3-O-(sinapoyl/caffeoyl)sophoroside-7-O-glucoside, kaempferol 3-O-(feruloyl/caffeoyl)sophoroside-7-O-glucoside, kaempferol 3-O-sophorotrioside, kaempferol 3-O-(sinapoyl)sophoroside, kaempferol 3-O-(feruloyl)sophorotrioside, kaempferol 3-O-(feruloyl)sophoroside, kaempferol 3-O-sophoroside, and kaempferol 3-O-glucoside. These acylated derivatives are reported for the first time in nature, with the exception of kaempferol 3-O-(sinapoyl)sophoroside. Quantification of the identified compounds was achieved by HPLC-DAD and carried out in samples cultivated under conventional or organic practices and collected at different times. In general, samples from organic production exhibited higher total phenolics content than those from conventional practices collected in the same period.
