The phytochemistry of species of the genus Piper has been studied extensively, including Piper solmsianum . However, no studies have addressed the phytochemistry of the sap content of Piper species. Objective To evaluate the transferring of secondary compounds from the saps of P. solmsianum to the honeydew of Edessa meditabunda . Methodology The honeydew of E. meditabunda and saps of P. solmsianum were analysed by GC‐MS, 1 H‐NMR and LC‐MS. Results The lignan (−)‐grandisin and the phenylpropanoid ( E )‐isoelemicin were detected in both saps of P. solmsianum and honeydew of E. meditabunda . Conclusion Analysis of honeydew secreted by the sap‐sucking insect E. meditabunda indicated that (−)‐grandisin and ( E )‐isoelemicin are absorbed from the phloem of Piper solmsianum .
