INTRODUCTION
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.
简介
椒属植物的植物化学已得到广泛研究，包括 Piper solmsianum。然而，尚未有研究涉及椒属植物 sap 液的植物化学。
目的
评估从 Piper solmsianum 的 sap 液转移到 Edessa meditabunda 的蜜露中的次生化合物。
方法
通过 GC-MS、(1)H-NMR 和 LC-MS 分析 E. meditabunda 的蜜露和 P. solmsianum 的 sap 液。
结果
在 P. solmsianum 的 sap 液和 E. meditabunda 的蜜露中均检测到木脂素（-）-大四叶苷和苯丙素（E）-异土木香内酯。
结论
对吸汁昆虫 E. meditabunda 分泌的蜜露的分析表明，(-)-大四叶苷和(E)-异土木香内酯是从 Piper solmsianum 的韧皮部吸收的。
