    摘要: A compound of the formula ##STR1## wherein R is .beta.-D-glucopyranosyl, .beta.-D-galactopyranosyl, 6'-O-acetyl-.beta.-D-glucopyranosy or 6'-O-acetyl-.beta.-D-galactopyranosyl, or a pharmaceutically acceptable salt thereof, has bronchodilator, cardiac activity, smooth muscle relaxant activity and hormone excretion stimulant activity. It can be produced by culturing a microorganism belonging to the genus Nodulisporium and adapted to produce the compound in a culture medium, and isolating the produced compound from the cultured medium. The microorganism can be Nodulisporium sp. M5220 FERM P-8133. The compounds have inhibitory activity on cyclic-adenosine-3',5'-monophosphate phosphodiesterase.
