The effects of various fractions from the aerial parts of Echinosophora koreensis Nakai on the antimutagenic and the immuno-regulating activities were evaluated by in vivo bone-marrow micronucleus test and HA titer reaction. No significant suppressive effects of these extracts and echinoisosophoranone were shown on cyclophosphamide-induced micronuclei, but HA titers were significantly enhanced in ether and BuOH extract treated-group. Tetracosanol and docosanol were isolated from the ether extract of this plant.

Seven prenylated flavonoids and two pterocarpans together with a saponin were isolated from the roots of Echinosophora koreensis. They were identical with echinoisosophoranone, echinoisoflavanone, isosophoranone, sophoraisoflavanone A, kenusanone C, kenusanone A, sophoraflavanone D, 4-hydroxy-3-methoxy-(6aR,11aR)-8,9-methylenedioxy-pterocarpans, (-)-maackiain, and $3-O-{\alpha}-L-rhamnopyranosyl(1{\rightarrow}2)-{\beta}-D-galactopyranosyl(1{\rightarrow}2)-{\beta}-D-glucuronopyranosyl$ kuzusapogenol A. Among them, a pterocarpan, 4-hydroxy-3-methoxy-(6aR,11aR)-8,9-methylenedioxypterocarpan, and a saponin, $3-O-{\alpha}-L-rhamnopyranosyl(1{\rightarrow}2)-{\beta}- D-galactopyranosyl(l{\rightarrow}2)-{\beta}-D-glucuronopyranosyl$ kuzusapogenol A, were isolated for the first time from this plant.
