Abstract

Abstract Eleven chemical constituents were isolated from the ethyl acetate soluble fraction of the aerial part of Rosa laevigata Michx. These compounds include the Henze's ketol (16), diethyl malate (17), three γ‐lactones (18‐20), loliolide (21), p‐coumaric acid (22), 6,7‐dimethoxycoumarin (23) and three flavonoids (24‐26). The new compounds 19 and 20 were determined to be the cis‐ and trans‐isomers of ethyl 2‐benzyl‐3‐hydroxy‐5‐oxo‐3‐furancarboxylate.
