摘要

摘要:本研究旨在评价叶边胡椒(Piper marginatum Jacq)叶和花椒(Piper callosum Ruiz & Pav)气生部位(枝、叶、花序)精油的化学成分特征和杀螨活性。从胼胝体的空气部分(枝、叶和花序)中提取三种不同的精油，其化学成分含量不同。边草挥发油中主要化合物为δ-3-蒈烯和(E)-β-辛烯，而胼胼草挥发油中主要化合物为红花素。4 μL/L的边草挥发油浓度和2 μL/L的胼白桃挥发油浓度对72 h后的螨虫均有杀灭作用。50%致死浓度为1.19 ~ 2.16µl/ l，胼胝体为1.22 ~ 3.44µl/ l。

Chemical composition and acaricidal activity of the essential oils of Piper marginatum and Piper callosum collected in the Amazon region

ABSTRACT The objective of this study was to evaluate the chemical profile and acaricidal activity against the mite Suidasia pontifica of the essential oils from leaves of Piper marginatum Jacq and aerial parts (branches, leaves, and inflorescences) of Piper callosum Ruiz & Pav. From the aerial parts (branches, leaves and inflorescences) of P. callosum, three different essential oils were extracted with variations in the contents of their chemical constituents. The major compounds in the essential oil of P. marginatum were δ-3-carene and (E)-β-ocimene, while safrole was the predominant compound in the essential oils of P. callosum. Concentrations of 4 μL/L of the essential oil of P. marginatum and 2 μL/L of the essential oil of P. callosum killed all the mites tested after 72 h of exposure. The 50% lethal concentration ranged from 1.19 to 2.16 µl/L air for P. marginatum and from 1.22 to 3.44 µl/L air for P. callosum.

期刊介绍： Journal of Essential Oil Research ( JEOR) is the major forum for the publication of essential oil research and analysis. Each issue includes studies performed on the chemical composition of some of the 20,000 aromatic plants known in the plant kingdom. JEOR is devoted entirely to all phases of research from every corner of the world by the experts in their field. JEOR''s main areas of focus include: -Analytical chemistry- Biological activity- Biotechnology- Chemical composition- Chemical synthesis- Chemosystematics- Microbiological activity- Plant biochemistry/biosynthesis- Toxicology. Published six times per year, JEOR provides articles on the aromatic principles of a plant or its isolates and are directed toward furthering our readers'' knowledge of the aromatic plant and animal kingdoms.
