Abstract

A physiologically-active novel substance "aldostatin" having an estimated molecular formula of C.sub.20 H.sub.20 N.sub.2 O.sub.8 is produced by culturing an aldostatin-producing microorganism of the Pseudeurotium, for example, the Pseudeurotium zonatum M4109 strain. Aldostatin inhibits the aldose reductase activity and as a consequence, avoids abnormal accumulation of sorbitol, galactitol, etc. It is therefore effective for the treatment of chronic complications such as cataract, retinopathy and neuropathy caused by diabetes renalis.
