Abstract

AbstractColumn chromatography of the chloroform extract of Hemerocallis fulva afforded chrysophanol, methyl rhein, l,8-dihydroxy-3-methoxy-anthraquinone and rhein. The unsaponifiable matter yielded a long chain hydrocarbon, a long chain ester, a long chain alcohol and β-sitosterol. The aqueous fraction yielded choline. The structures of these compounds were established on physico-chemical bases and direct comparison with authentic samples. The plant extracts as well as some isolated compounds have shown antimicrobial activity.
