A Straight-Chain Alcohol Glycoside, with Smooth Muscle Relaxant Activity, from Rubus idaeus (Raspberry) Leaves

A methanolic extract of Rubus idaeus leaves, when fractionated by column chromatography, yielded two distinct bands containing compounds that demonstrated in vitro, dose dependent, smooth muscle relaxant activity using transmurally-stimulated Guinea pig ileum preparations. From band two, following extensive chromatographic separation, several compounds with smooth muscle relaxant activity were obtained, one of which was characterized, from...
