? 2022Despite being rich in phenylpropanoids with insecticidal activity, Piper marginatum leaves are frequently attacked by the larvae of the Quadrus u-lucida moth. GC/MS analysis indicated isomerization of phenylpropanoid (Z)-asarone to (E)-asarone from the leaves by larvae. The phenylpropanoids (Z)-asarone, dillapiole and (E)-asarone were identified in concentrations of 48.01, 24.02 and 36.07 μg/mg, respectively. Only the phenylpropanoid (E)-asarone was found in the larval tissues and regurgitant material in a concentration of 15.52 and 2.53 μg/mg, respectively. Since (Z)-asarone has been reported to be more toxic than (E)-asarone, the isomerization of (Z)-asarone may be associated with the detoxification mechanism of larvae.
