ABSTRACT:
A novel valiolamine derivative of the formula (I): ##STR1## where R stands for hydrogen or .beta.-D-glucopyranosyl group is useful for a starting material of valiolamine which can be converted to more potent .alpha.-glucosidase inhibiting compounds. The valiolamine derivative is obtained by cultivating Streptomyces hygroscopics in a culture medium and recovering the valiolamine derivative produced and accumulated from the culture broth.
