2,3-Dihydro-2-(4'-hydroxyphenyl)-3-methyl-5(E)-propenylbenzofuran (conocarpan) (1), 2-(4'-hydroxy-3'-methoxyphenyl)-3-methyl-5(E)- propenylbenzofuran (eupomatenoid-5) (2), and 2-(4'- hydroxyphenyl)-3-methyl-5(E)-propenylbenzofuran (eupomatenoid-6) (3), three known neolignans found for the first time in a species of the Piperaceae, were isolated from Piper decurrens via insecticidal bioassay-guided fractionation, along with a small quantity of a new related compound, 2,3-dihydro-5-formyl-2-(4'-hydroxyphenyl)-3-methylbenzofuran (decurrenal) (4), and 3,7,11,15-tetramethyl-2(E)-hexadecen-1-ol (trans-phytol).
2,3-二氢-2-(4'-羟基苯基)-3-甲基-5(E)-丙烯基苯并呋喃（柯诺卡潘）(1)、2-(4'-羟基-3'-甲氧基苯基)-3-甲基-5(E)-丙烯基苯并呋喃（优波马替诺-5）(2)和2-(4'-羟基苯基)-3-甲基-5(E)-丙烯基苯并呋喃（优波马替诺-6）(3)，这三种首次在胡椒科某一物种中发现的已知新木脂素，是通过杀虫生物测定引导的分级分离法从垂穗胡椒中分离得到的，同时还得到了少量新的相关化合物2,3-二氢-5-甲酰基-2-(4'-羟基苯基)-3-甲基苯并呋喃（垂穗胡椒醛）(4)和3,7,11,15-四甲基-2(E)-十六碳烯-1-醇（反式叶绿醇）。
