Abstract
Callus and suspension cultures of the liverwort, Heteroscyphus planus accumulated novel diterpenoid acids of the clerodane-type, namely, (12 Z)-5,10-trans-cleroda-3,12,14-trien-20-oic acid (heteroscyphic acid A) , -6-acetoxy-5,10-trans-cleroda-3,12,14-trien-20-oic acid (heteroscyph ic acid B) and (12Z)-3,4-epoxy-6-acetoxy-5,10-trans-cleroda-12, 14-die n-20-oic acid (heteroscyphic acid C). Their structures and relative st ereochemistry were elucidated on the basis of spectroscopic evidence t ogether with chemical transformation.
