The abstract shows pentacyclic triterpenoids (including oleanolic acid) correlated with tyrosinase inhibition, but did not directly test the whitening efficacy of oleanolic acid, only inferred via correlation.
Oleanolic acid was isolated and tested for cholinesterase inhibition, but not for tyrosinase inhibition (whitening-related); only polar extracts showed tyrosinase activity, not attributed to oleanolic acid.
