Cytotoxicity of Essential Oils from Murraya paniculata (L.) Jack. and their Biological Potential Against Fungi of Agronomic Interest

Fungos fitopatogênicos causam perdas significativas na agroindústria. O ensaio de toxicidade em que se utiliza Artemia salina é preliminar e altamente sensível a diversos tipos de compostos químicos. Portanto, este estudo descreveu as atividades citotóxica e antifúngica dos óleos essenciais (OEs) das folhas de Murraya paniculata (ML-EO) e de seus frutos (MF-EO), extraídos por hidrodestilação.Os óleos essenciais foram analisados por CG-EM e CG-DIC, enquanto as atividades citotóxica e antifúngica foram avaliadas pelo teste da Artemia salina e pelo método de difusão em disco, respectivamente. Os compostos majoritários foram β-cariofileno (20,8%), α-zingibereno (20,0%) e β-cubebeno (13,2%) e para MF-EO foram identificados β-cariofileno (20,1%), germacreno D (18,0%) e α-zingibereno (15,2%). No ensaio de citotoxicidade, os valores de LC50 para ML-EO e MF-EO foram 1785,3 e 1549,2 μg/mL, respectivamente. ML-EO e MF-EO foram avaliados contra Cladosporium cladosporioides, Colletotrichum gloeosporioides, Fusarium solani e Rhizopus stolonifer. ML-EO e MF-EO mostraram satisfatórios resultados de inibição do crescimento micelial na dose de 300 µL com valores entre 54-83% e revelou fraca atividade contra F. solani. Os óleos essenciais de M. paniculata apresentou LC50 > 1000 μg/mL, não sendo citotóxicos. A novidade e que os dois óleos estudados representam uma alternative natural para o controle de fungos pós-colheita e para estender a vida de prateleira de produtos agrícolas.

  • Abstract:

    Phytopathogenic fungi cause significant economic losses in the agroindustry. The brine shrimp (Artemia salina) assay is a convenient preliminary toxicity test, because brine shrimps are highly sensitive to several chemical compounds. Therefore, this study described cytotoxic and antifungal activities of essential oils (OEs) from Murraya paniculata leaves (ML-EO) and fruit (MF-EO) extracted by hydrodistillation. EOs were analyzed by GC-FID and GC-MS, while cytotoxic and antifungal activities were evaluated by the brine shrimp lethality test and the disc-diffusion method, respectively. Major compounds of ML-EO were β-caryophyllene (20.8%), α-zingiberene (20.0%) and β-cubebene (13.2%) and the ones of MF-EO were β-caryophyllene (20.1%), germacrene D (18.0%) and α-zingiberene (15.2%). In the cytotoxic assay, LC50 values of ML-EO and MF-EO were 1785.3 and 1549.2 μg/mL, respectively. ML-EO and MF-EO were evaluated against Cladosporium cladosporioides, Colletotrichum gloeosporioides, Fusarium solani and Rhizopus stolonifer. ML-EO and MF-EO showed satisfactory results between 54-83% inhibition of mycelial growth at 300 µL and revealed weak activity against F. solani. EOs from M. paniculata had LC50 > 1000 μg/mL, which is not cytotoxic. The novelty is that both ML-EO and MF-EO represent a natural alternative to control post-harvest fungi and to extend shelf-life of agricultural products.
