ABSTRACT
The aim of the present study was to evaluate the in vitro antiproliferative activity of ethanolic extract of leaves and fruits Citrus paradisi plant on HepG-2 liver cell lines by MTT (3-(4, 5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-terazolium bromide) assay and to isolate and characterize the antiproliferative compounds by TLC (Thin layer chromatography) and FT-IR (Fourier transforms Infrared) spectroscopy. Qualitative phytochemical screening tests were performed to detect phytochemicals compounds from the crude extracts. Antioxidant activity of the plant extracts were characterized by using DPPH (2,2-Diphenyl-1-picrylhydrazyl) free radical scavenging method. The results showed that antioxidant activity using DPPH were found to be increased in a concentration dependent manner and decreased cell viability and cell growth inhibition in a dose dependent manner. The findings from this study indicated that fruit extract exhibited good antiproliferation and antioxidant potential. The seven functional groups of phytocompounds such as carboxylic acid, amine salt, aromatic compounds, cyclic alkene, aldehyde, fluoro compounds and alkene were detected by FT-IR which indicated that fruit extracts of Citrus paradisi possessed vast potential as a medicinal drug especially in liver cancer treatment.

Resumo O objetivo do presente estudo foi avaliar a atividade antiproliferativa in vitro do extrato etanólico de folhas e frutos da planta Citrus paradisi em linhagens de células hepáticas HepG-2 por MTT (3- (4, 5-dimetil-2-tiazolil) -2, Ensaio de brometo de 5-difenil-2H-terazólio) e isolar e caracterizar os compostos antiproliferativos por espectroscopia de TLC (cromatografia de camada fina) e FT-IR (infravermelho com transformadas de Fourier). Testes qualitativos de triagem fitoquímica foram realizados para detectar compostos fitoquímicos nos extratos brutos. A atividade antioxidante dos extratos vegetais foi caracterizada pelo método de eliminação de radicais livres DPPH (2,2-difenil-1-picrilhidrazil). Os resultados mostraram que a atividade antioxidante usando DPPH aumentou de uma maneira dependente da concentração e diminuiu a viabilidade celular e a inibição do crescimento celular de uma maneira dependente da dose. Os resultados deste estudo indicaram que o extrato de fruta exibiu bom potencial antiproliferação e antioxidante. Os sete grupos funcionais de fitocompostos, como ácido carboxílico, sal de amina, compostos aromáticos, alceno cíclico, aldeído, compostos de flúor e alceno, foram detectados por FT-IR, o que indicou que extratos de frutas de Citrus paradisi possuíam vasto potencial como medicamento, especialmente no tratamento de câncer do fígado.
