Abstract

Abstract: A new flavonoid dimer, strictatin (10 ), was identified from the aerial part of Conyza stricta, in addition to eleven known compounds. The structure of compound 10 was determined by spectral analyses, including 1D, 2D NMR and HR-ESI-MS experiments. All compounds were identified from Conyza stricta for the first time and flavonoid dimers were firstly reported from the family Asteraceae. The chemotaxonomic significance of the identified metabolites was discussed. Graphical abstract: Image 1 Highlights: Totally twelve compounds were isolated from Conyza stricta. All isolated compounds were identified for the first time from Conyza stricta. The flavonoid dimers were first time report from family Asteraceae.
