Abstract
A hot-water extract of the bark of Melia azadirachta L. is treated with a gel filtrating agent with a fractionation range molecular weight from 1.times.10.sup.3 -1.times.10.sup.5 to 1.times.10.sup.3 -1.5.times.10.sup.5. There is obtained polysaccharide N9GI from the first fraction of the three divided polysaccharide fractions. Polysaccharide N9GI further treated with a gel-filtrating agent with a fractionation range molecular weight from 1.times.10.sup.3 -2.times.10.sup.5 to 1.times.10.sup.3 -8.times.10.sup.5. There are obtained polysaccharide N9GIa and polysaccharide N9GIb respectively from the first and second fractions of the two divided polysaccharide fractions.
