Cis-piceid was more efficient than truns-piceid (pcO.O5), but considering the activities of the
aglycones of these compounds, truns-resveratrol was more potent than cis-resveratrol (~~0.05).
Radical scavenger activity was increased with the aglycone forms of these products (cisresveratrol
vs cis-piceid and trans-resveratrol vs truns-piceid; ~~0.05 and p
