The chemical composition of essential oils (EOs) from ten Peruvian Piper species (Piper coruscans, Pc; P. tuberculatum, Pt; P. casapiense, Pcs; P. obliquum, Po; P. dumosum, Pd; P. anonifolium, Pa; P. reticulatum, Pr; P. soledadense, Ps; P. sancti-felicis, Psf and P. mituense, Pm) has been studied, along with their antifungal and phytotoxic activities. These EOs contained β-bisabolene/nerolidol (Pc), β-bisabolene/δ-cadinene/caryophyllene (Pt), caryophyllene oxide (Pcs), bicyclogermacrene/10-epi-Elemol (Po), bicyclogermacrene/germacrene-D/apiol (Pd), caryophyllene/germacrene-D (Pa), germacrene-D (Pr), limonene/apiol (Ps), apiol (Psf), and apiol/bicyclogermacrene (Pm) as major components, and some are described here for the first time (Ps, Pcs, Pm). A composition-based dendrogram of these Piper species showed four major groups (G1: Pc and Pt, G2: Pcs, Po, Pd, Pa, and Pr, G3: Ps, and G4: Psf and Pm). The spore germination effects (Aspergillus niger, Botrytis cinerea, and Alternaria alternate) and phytotoxicity (Lolium perenne and Lactuca sativa) of these EOs were studied. Most of these Piper essential oils showed important activity against phytopathogenic fungi (except G1), especially against B. cinerea. Similarly, most of the essential oils were phytotoxic against L. perenne (except G1), with P. sancti-felicis (G4), P. casapiense (G2), and P. reticulatum (G2) being the most effective. Caryophyllene oxide, β-caryophyllene, β-pinene, limonene, α-humulene, and apiol were evaluated against B. cinerea, with the most effective compounds being β-pinene, apiol, and limonene. This work demonstrates the species-dependent potential of essential oils from Peruvian Piper species as fungicidal and herbicidal agents.
对来自秘鲁的10种胡椒属植物（亮叶胡椒、瘤果胡椒、卡萨皮胡椒、斜叶胡椒、丛生胡椒、茴芹叶胡椒、网脉胡椒、索莱达胡椒、圣费利克斯胡椒和米图胡椒）的精油化学成分及其抗真菌和植物毒性活性进行了研究。这些精油的主要成分包括β-红没药烯/橙花叔醇（亮叶胡椒）、β-红没药烯/δ-杜松烯/石竹烯（瘤果胡椒）、氧化石竹烯（卡萨皮胡椒）、双环吉玛烯/10-表榄香醇（斜叶胡椒）、双环吉玛烯/吉玛烯-D/芹子烯（丛生胡椒）、石竹烯/吉玛烯-D（茴芹叶胡椒）、吉玛烯-D（网脉胡椒）、柠檬烯/芹子烯（索莱达胡椒）、芹子烯（圣费利克斯胡椒）以及芹子烯/双环吉玛烯（米图胡椒），其中一些成分在此首次被描述（索莱达胡椒、卡萨皮胡椒、米图胡椒）。基于成分的这些胡椒属植物的树状图显示出四个主要类群（G1：亮叶胡椒和瘤果胡椒，G2：卡萨皮胡椒、斜叶胡椒、丛生胡椒、茴芹叶胡椒和网脉胡椒，G3：索莱达胡椒，G4：圣费利克斯胡椒和米图胡椒）。研究了这些精油对孢子萌发的影响（黑曲霉、灰葡萄孢和链格孢）以及植物毒性（多年生黑麦草和莴苣）。这些胡椒属植物的大多数精油对植物病原真菌显示出重要活性（G1除外），尤其是对灰葡萄孢。同样，大多数精油对多年生黑麦草具有植物毒性（G1除外），其中圣费利克斯胡椒（G4）、卡萨皮胡椒（G2）和网脉胡椒（G2）最为有效。对氧化石竹烯、β-石竹烯、β-蒎烯、柠檬烯、α-葎草烯和芹子烯针对灰葡萄孢进行了评估，最有效的化合物是β-蒎烯、芹子烯和柠檬烯。这项工作证明了秘鲁胡椒属植物精油作为杀真菌剂和除草剂具有物种依赖性潜力。
