Abstract
Rumex abyssinicus, family polygonaceae is a plant
used traditionally for colouring textiles and food. It
has several medicinal application such as purgative, antidiabetic,
and taencide. l'he powdered root of R0abyssinicus
was packed on a column and extracted using acetone.
The sticky brownish mass(A-l)which was produced on
evaporation was further separated by column chromatography
and showed to consist of anthraquinone derivatives
A-4, A-6 and A-7 which were latter identified as emodin
(1,3,8 trihydroxy-6-methylanthraquinone), chrysopyanvl
(1,8 dihydroxyT3-methylanthraquinone, and physicone
(1,8 dihydroxy-3-methoxy-6-raethylanth-raquinone)respectively.
The structural ilucidation of emodin, chryso~phanol and physicone are based on their ultraviolet,visible, infrared, nuclear magnetic resonance and massspectras.
