چکیده انگلیسی
Surface flavonoids in nine species of Origanum, representing taxa from all three of the currently recognised subgeneric groups, were examined both by HPLC coupled to diode-array detection and APCI–MS. Many of the flavonoids present were characterised by O-substituent at C-6 (OH, OMe) and/or C-8 (OMe). In total, 25 flavones and flavanones are described in this study, of which 13 are new to the genus and 5,4′-dihydroxy-6,7,3′-trimethoxyflavanone is reported for the first time. Taxa in subgeneric Group A accumulated flavonoids with methoxyl groups at both C-6 and C-4′; however, taxa in subgeneric Group B did not accumulate 4′-methoxylated compounds, and taxa in Group C did not accumulate 6-methoxylated compounds.
