Chemical Composition, Insecticidal, and Antifungal Activities of Fruit Essential Oils of Three Colombian Zanthoxylum Species
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...

Zusammenfassung: | 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 main constituents
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 fung9icides 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.
