Abstract The material balance for the biotransformation of grindelic acid by Aspergillus niger was determined along with the isolation of two novel dimers identified as methyl-8α-hydroxy-grindelate-7β- O -7′β-ether hydrate and methyl-3β-acetoxy-8α-hydroxy-grindelate-7β- O -7′β-ether hydrate. Also identified were the known 19-hydroxy-grindelic acid and the novel 6α,17-dihydroxy-grindelic acid. All compounds
