abstract：:Abstract Twenty-three phenolic compounds were isolated from Dioscorea opposita by bioactivity-guided method and their inhibitory effect against pancreatic lipase was evaluated. A total of 15 isolates reduced lipase activity at IC50 values of less than 50 µM and 3,3',5-trihydroxy-2'-methoxybibenzyl showed the highest i...
