The Chemical Constituents from the Aerial Part ofRosa laevigata

摘要

AbstractEleven chemical constituents were isolated from the ethyl acetate soluble fraction of the aerial part ofRosa laevigataMichx. 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 thecis‐andtrans‐isomers of ethyl 2‐benzyl‐3‐hydroxy‐5
