  (12) were newly synthesized using 2β,3α-dihydroxy-11-oxo-18β-olean-12-ene-30-oic acid (1) and 2α,2β-dihydroxy-18β-ursan-12-ene-28-oic acid (7) as starting materials. The synthesized compounds were evaluated for their cytotoxicity and antioxidant activities and were compared to Oxaliplatin® and vitamin C as positive controls. Some of the compounds exhibited better cytotoxicity and antioxidant activities
