Bioassay-guided fractionation of the MeOH extract of Pteropi faeces (the feces of Trogopterus xanthipes Milne-Edwards) furnished three hyaluronidase inhibitory active 6H-dibenzo[b,d]-pyran-6-ones (1-3), together with a new compound, 3,8,10-trihydroxy-6H-dibenzo[b,d]pyran-6-one (4). Their structures were established on the basis of the spectroscopic methods.
