A new phenylbutanone glucoside, dorycnioside, was isolated from the methanol extract of the aerial parts of Dorycnium pentaphyllum subsp. herbaceum Vill. (Rouy) and identified as 4-(4'-O-beta-D-glucopyranosyl-3',5'-dimethoxyphenyl)-2-butanone (1). In addition, two known phenylbutanone glucosides,
Melilotus albus Medic. and Dorycnium herbaceum Vill. (Fabaceae) acetone, ethyl acetate, and ethanol extracts were investigated for their in vitro antimicrobial, antibiofilm, and antioxidant activity with quantification of phenolic compound contents. In general, D. herbaceum extracts showed better
