Cytotoxic evaluation of essential oil from Casearia sylvestris Sw on human cancer cells and erythrocytes

Abstract: Casearia sylvestris (Flacourtiaceae) is a plant popularly known as "guaçatonga" and it is used by indigenous population from South America (Brazil, Peru and Bolivia) in the treatment of several diseases, including cancer. Cytotoxic studies showed that it presents an interesting antitumoral potential due to the presence of casearins and the essential oil showed a high percentage of potent cytotoxic sesquiterpenes (β-caryophyllene and α-humulene). In this work, we verified that the essential oil of C. sylvestri… Show more

“…Various reports showed that the major constituents in the oils such as b-caryophellene, a-humulene, caryophyllene oxide and belemene exhibited cytotoxic activity against different cell lines. Their potency could be as a result of higher percentage of b-caryophellene and a-humulene present in the fractions, since (E)-bcaryophellene and a-humulene have been reported to be cytotoxic against several human cancer cell lines, such as Hela, MCF-7, MDA-MB-468, UACC-257, DLD-1, A549 and HT-29 (Cole et al 2007;Legault & Pichette 2007;Silva et al 2008;Su & Ho 2013). Owolabi et al (2013) reported in vitro cytotoxicity activity of (E)-b-caryophellene, caryophyllene oxide and a-humulene obtained from A. muricana leaf oil against MCF-7 cells with LC 50 values of 38.8, 23.0 and 22.1 lg/mL.…”

“…sylvestris es una planta utilizada por indí-genas de América del Sur para el tratamiento de varias enfermedades, incluyendo cáncer 8 . Nuestros resultados podrían explicar, al menos en parte, las propiedades antitumorales que se le atribuyen a esta planta (pues la casearina G es, según datos aún no publicados, el diterpeno tipo clerodano más abundante en esta planta), toda vez que la casearina G mostró efecto citotóxico y citostático in vitro contra células tumorales PC-3 y MCF-7.…”

Estudios previos de citotoxicidad muestran que la CD 50 (que en nuestro artículo se define como IC 50 ) del aceite de C. sylvestris para las células tumorales HeLa, A-549 y HT-29 es 63,3, 60,7 y 90,6 μg/ml, respectivamente 8 . También reportamos que la IC 50 de la casearina G para las células tumorales PC-3 y MCF-7 es 13,3 y 11,8 μM, respectivamente.…”
