Camellia consists of many plants of high economic importance that are used in different fields, especially in the food industry. Camellia cattienensis is a rare species and is native to Vietnam. Studies on the phytochemical and biological properties of this species have been unknown so far. In this study, the chemical components of the acetone extract from C. cattienensis leaves and its fractions, including n-hexane, chloroform, and ethyl acetate, were investigated using gas chromatography-mass spectrometry assay. Accordingly, 2-pentanone, 4-hydroxy-4-methyl- was the most abundant compound in the acetone extract and the ethyl acetate fraction, while phenol, 2,4-bis(1,1-dimethylethyl)-, phosphite (3:1) and hexanedioic acid, bis(2-ethylhexyl) ester are the richest components in the chloroform and n-hexane fractions, respectively. Furthermore, the acetone extract was active against four tested bacteria, including Klebsiella pneumoniae, Staphylococcus aureus, and Staphylococcus saprophyticus BAA750. The acetone extract of the C. cattienensis leaves also possessed DPPH, and ABTS free radical scavenging with the IC50 values of 91.63±1.88 and 13.32±0.49 μL, respectively. The outcomes of this study hold promise for potential applications of C. cattienensis leaves in food product development, especially in the future beverage industry.
La Camelia se compone de muchas plantas de alto valor económico y se utilizan en diferentes campos, especialmente en la industria alimentaria. Camellia cattienensis es una especie rara y originaria de Vietnam. Hasta el momento se desconocen los estudios sobre las propiedades fitoquímicas y biológicas de esta especie. En este estudio, se investigaron los componentes químicos del extracto de acetona de las hojas de C. cattienensis y sus fracciones, como n-hexano, acetato de etilo y cloroformo, mediante un ensayo de cromatografía de gases/espectrometría de masas. En consecuencia, 2-pentanona, 4-hidroxi-4-metil-fue el compuesto más abundante en el extracto de acetona y la fracción de acetato de etilo, mientras que fenol, 2,4-bis(1,1-dimetiletil)-, fosfito (3:1) y el ácido hexanodioico, el éster bis(2-etilhexílico) son los componentes más ricos en las fracciones de cloroformo y n-hexano, respectivamente. Además, se descubrió que el extracto de acetona era eficaz contra cuatro bacterias analizadas, incluidas Klebsiella pneumoniae, Staphylococcus aureus, y Staphylococcus saprophyticus. El extracto de acetona de las hojas de C. cattienensis también poseía eliminación de radicales libres DPPH y ABTS con valores de IC50 de 91,63±1,88 y 13,32±0,49 μL, respectivamente. Los resultados de este estudio son prometedores para aplicaciones potenciales de las hojas de C. cattienensis en el desarrollo de productos alimenticios, especialmente en la industria de bebidas en el futuro.
