ABSTRACT An aqueous extract product which is effective for prevention or treatment of hypertension is produced by: concentrating an aqueous extract obtained by: extract- ing water-soluble components from vegetable oils such as soybean oil, corn oil, rapeseed oil and cotton seed oil, adding a lower alcohol to the resulting extract to prepare an alcoholic solution having an alcohol concent- ration above 85%, thereby precipitating the insoluble matter; then removing the precipitates; and thereafter removing the alcohol. A powdered product having an antihypertensive activity is also produced by: subject- ing said aqueous extract product to an additional optional purification step and thereafter concentrating the resulting product to obtain a powder. An antihyper- tensive agent containing a novel substance OSG as an effective component is also disclosed.
