GLYCOSIDES OF MAGNOLIA GRANDIFLORA

Abstract

From the bark of Magnolia grandiflora L. are isolated three crystalline glycosides named magnolidin, magnolenin and magnosidin in addition to the known alkaloids magnoflorine and candicine. The water-soluble fraction of the alcoholic extract was chromatographed on Sephadex–LH 20 from which were eluted successively the alkaloid mixture, the magnolenin-magnosidin mixture and finally, magnolidin. Each was subsequently purified and characterized. Magnolidin is the major glycoside of the bark.
