10968284-4	2000	Bioassay-guided fractionation of the extract, guided by an assay to detect DNA polymerase beta inhibition, resulted in the isolation of six active pentacyclic triterpenoids (1-6).	triterpenoids	159-172	DNA polymerase beta	Homo sapiens	75-94	
10654412-3	1999	Bioassay-guided fractionation of the extract, using an assay to monitor the inhibitory potential of individual fractions toward DNA polymerase beta, led to the isolation of four active ursane and oleanane triterpenoids (1-4).	triterpenoids	205-218	DNA polymerase beta	Homo sapiens	128-147
