HF-WE, water extract of H. fulva; HF-EE, ethanol extract of H. fulva; Elastatinal, positive control.
All values are mean±SD (n=3).
Different lowercase letters (^a-c) within the same column indicate significant differences among samples at the same concentration (p<0.05). Different uppercase letters (^A-F) within the same row indicate significant differences among concentrations within the same sample (p<0.05), based on Duncan’s multiple range test.
