PURPOSE:To provide the titled agent free from side effect, and containing the hypotensive component of the juice of raw leaves of gramineous plant as an active component. CONSTITUTION:An aqueous solution of a water-soluble component of the juice obtained from the raw leaves of a gramineous plant is mixed with 60-80vol%, based on the aqueous solution, of a polar solvent (e.g. methanol) and/or the solution is heated at 70-100 deg.C. The produced insoluble solid component is removed from the juice, and if necessary, the obtained liquid is subjected to gel-filtration treatment, and the product is used as the active component. The juice contains complex natural components, and the nature and the composition of the hypotensive components in the complex system are still unknown. However, the component can be used as a drug effective to various hypotensions without causing side effects e.g. by oral administration, intravenous injection, subcutaneous injection, etc. |
