Abstract

This study determined the chemical composition of essential oils isolated from Zanthoxylum monophyllum (Lam.) P. Wilson, Z. rhoifolium Lam., and Z. fagara (L.) Sarg. fruits by steam distillation, as well as testing antifungal and insecticidal activities of essential oils as potential pesticides. Gas chromatography-mass spectrometry (GC/MS) analysis identified 57 compounds. The main constituents in Z. rhoifolium oil were β-Myrcene (59.03%), β-phellandrene (21.47%), and germacrene D (9.28%) , the major constituents of Z. monophyllum oil were sabinene (25.71%), 1,8-cineole (9.19%), and cis-4-thujanol (9.19%), whereas fruit oil of Z. fagara mainly contained germacrene D-4-ol (21.1%), elemol (8.35%), and α-cadinol (8.22%). Zanthoxylum fagara showed the highest activity on Colletotrichum acutatum Simmonds (EC50 153.9 μL L-1 air), and Z. monophyllum was the most active against Fusarium oxysporum Schlechtend: Fr. f. sp. lycopersici (EC50 140.1 μL L-1 air). Zanthoxylum monophyllum essential oil showed significant fumigant activity against Sitophilus oryzae (L.). This study demonstrated that Zanthoxylum essential oils exhibit important fungicidal activity on F. oxysporum and C. acutatum, which could become an alternative to synthetic fungicides to control plant fungal diseases, and Z. monophyllum oil is a potential fumigant against S. oryzae.

En este estudio se determinó la composición química de los aceites esenciales de frutos de Zanthoxylum monophyllum (Lam.) P. Wilson, Z. rhoifolium Lam. y Z. fagara (L.) Sarg. obtenidos mediante destilación por arrastre con vapor y se evaluó la actividad antifúngica e insecticida de los aceites esenciales para estimar su uso como posibles plaguicidas. El análisis por cromatografía de gases-espectrometría de masas (CG/EM) permitió la identificación de 57 compuestos. β-Mirceno (59,03%), β-felandreno (21,47%) y germacreno D (9,28%) fueron los componentes principales del aceite de Z. rhoifolium; los principales componentes del aceite de Z. monophyllum fueron sabineno (25,71%), 1,8 -cineol (9,19%) y cis-4-thujanol (9,19%), mientras que el aceite de frutos de Z. fagara está compuesto principalmente por germacreno D-4-ol (21,1%), elemol (8,35%) y α-cadinol (8,22% ). Zanthoxylum fagara presentó la mayor actividad sobre Colletotrichum acutatum Simmonds (EC50 153,9 μL L-1 de aire) y Z. monophyllum fue el más activo contra Fusarium oxysporum Schlechtend: Fr. f. sp. lycopersici (EC50 140,1 μL L-1 de aire). El aceite esencial de Z. monophyllum mostró actividad insecticida significativa contra Sitophilus oryzae (L.) Este estudio demuestra que los aceites esenciales de Zanthoxylum poseen importante actividad antifúngica sobre F. oxysporum y C. acutatum y podría convertirse en una alternativa frente a los fungicidas sintéticos empleados comúnmente para el control de enfermedades de las plantas, así como el aceite de frutos de Z. monophyllum tiene un potencial para ser utilizado como fumigante contra S. oryzae.

Botanical insecticides, deterrents, and repellents in modern agriculture and an increasingly regulated world.

Murray Isman (2006)

Botanical insecticides have long been touted as attractive alternatives to synthetic chemical insecticides for pest management because botanicals reputedly pose little threat to the environment or to human health. The body of scientific literature documenting bioactivity of plant derivatives to arthropod pests continues to expand, yet only a handful of botanicals are currently used in agriculture in the industrialized world, and there are few prospects for commercial development of new botanical products. Pyrethrum and neem are well established commercially, pesticides based on plant essential oils have recently entered the marketplace, and the use of rotenone appears to be waning. A number of plant substances have been considered for use as insect antifeedants or repellents, but apart from some natural mosquito repellents, little commercial success has ensued for plant substances that modify arthropod behavior. Several factors appear to limit the success of botanicals, most notably regulatory barriers and the availability of competing products (newer synthetics, fermentation products, microbials) that are cost-effective and relatively safe compared with their predecessors. In the context of agricultural pest management, botanical insecticides are best suited for use in organic food production in industrialized countries but can play a much greater role in the production and postharvest protection of food in developing countries.
