Prunus serrulata var. spontanea(Rosaceae) is a large sized tree widely distributed throughout Korea. The red fruits are edible and are used in traditional folk medicine against heart failure from beriberi. dropsy. mastitis, an emmenagogue, and toothache. Also. the bark of P. serrulata var. spontanea has been used for detoxification. and relaxation and as an antitussive in traditional Korea medicine. (omitted)

As a part of finding the biologically active components from Duchesnea indica (Andr.) Focke (Rosaceae), antitumor activities of its water soluble fractions have been studied. The fractions were examined for antitumor activity against sarcoma 180 implanted in mice. The anitumor inhibition ratios of the water soluble fractions from Duchesnea indica were 17.9, 37.1, 62.1, 62.4%, repectively.

Four hydrolyzable tannins were isolated from the leaves of Rubus coreanum. The structures of these compounds were elucidated as methyl gallate(1), 1(${\beta}$)-O-galloyl pedun culagin(2), sanguiin H-2(3) and sanguiin H-6(4) on the basis of physicochemical and spectroscopic evidences. These compounds were found from this plant for the first time.

The physicochemical activities of the underground parts of Roso rugosa Thunb (Rosaceae) , which have been used as an antidiabetic in the folkmedicines of Korea , was carried outThe methanol extract from this plant reduced serum Lipid Level the normal rat . When various fractions from the methanol extract was administered to the rat treated with 1% choholesterol and 0.5% cholic aciddiet , the ethyl acetate soluble fraction lowered the serum triglycerideand phospholipid level most remarkably.

Antitumor and antimicrobial activities of water soluble fractions of Duchesnea indica (Andr.) and Focke (Rosaceae), have been studied. The contents of total polysaccharide were 22% and its composition was identified by G.C.: L-arabinose(Rt: 7.71), D-xylose (Rt. 9.91), D-glucuronic acid (Rt. 12.77), D-fructose (Rt. 13.63), D-galactose (Rt. 14.68), D-glucose (Rt. 15.42). The antimicrobial activity of Duchesnea indica against four bacterial species, S. aureus, S. paratyphi, S. dysenteriae and Ps. aeruginosa was observed.
