Abstract
A multi-functional physiologically active substance can be obtained from the residue of saccharified malt which has been worthless other than feed for cattle. The isolation of the active substance is performed by an extraction of the residue with water or an aqueous solvent and removal of a low molecular weight fraction from the extract.
Claims2
A pharmaceutical composition comprised of
- 1) an extract which is derived from malt residue and prepared by saccharification of malt, filtration of the saccharified mixture, extraction of the filtered residue with water or an aqueous solvent and removal of a low molecular weight fraction from the extract and wherein said extract has the following properties:
- (i) Molecular weight of from 19.8.times.10.sup.4 to 22.1.times.10.sup.4 daltons as determined by the GPC-LALLS method,
- (ii) Infrared absorption spectra at 3,600-3,200 cm.sup.-1 and 1,700-1,6000 cm.sup.-1,
- (iii) Proton nuclear magnetic resonance spectra having peaks at 0.5-6.0 ppm and 6.0-8.5 ppm,
- (iv) Ultraviolet absorption spectra at 200-250 nm and 250-350 nm,
- (v) Positive to phenol sulfuric acid color reaction, and
- (vi) Positive to copper-Folin color reaction, and
- 2) a pharmaceutically acceptable carrier or diluent.
