Explore the antiproliferative phytocompounds from ethanolic extracts of Citrus paradisi against liver cancer cell line by chemical analysis using TLC and FT-IR spectroscopy

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.

Effect of Annonaceous Acetogenins on Human Liver Cancer Cell Line HepG2 / 中国中医药信息杂志

Objective To observe the inhibitory action of annonaceous acetogenins AS-4 on human liver cancer cell line HepG2 in vitro. Method Using different concentration of annonaceous acetagenins group(6.25,12.5,25,50 ?g/mL),control group(25 ?g/mL) of masculine(DDP),control blank group,after routine culture of 24 or 48 hours,the effect of annonaceous acetogenins AS-4 on HepG2 was analyzed by colorimetry assay(MTT) and inverted phase-contrast microscope observing. Result AS-4 had the best inhibitory effect on HepG2,the highest inhibitory rate was 91.68%,and the effect was time-dosage dependent,and the 48 h IC50 was 6.67 ?g/mL. Conclusion AS-4 has lethal effect on HepG2 in vitro,and shows obvious cytotoxic effect.

The anti-tumor effect of ethaselen on transplanted liver cancer(H_(22)) and Lewis lung cancer mice / 西安交通大学学报(医学版)

Objective To observe the anti-tumor effect of ethaselen on transplanted liver cancer(H22)and Lewis lung cancer mice.Methods The transplanted liver cancer(H22)and Lewis lung cancer mice models were established.Each genus consisted of 60 mice,which were divided into control,CTX,and three ethaselen dose groups,respectively,with 12 mice in each.Intraperitoneal injection(ip.)of three dosages was performed once a day through the abdominal wall separately,from the second to the eighth day after cancer was transplanted.On the eleventh day,six mice in each group were killed to calculate the tumor inhibition ratio and observe the cell cycle by flow cytometry,and the others were observed for the life extension ratio.Results When ethaselen was given at the dosage of 25,12.5 and 6.3 mg/kg,the tumor inhibition ratio was 52.5%,43.6% and 30.2%,and the life extension ratio was 56.6%,38.7% and 14.2% in the transplanted liver cancer(H22)mice,respectively.The tumor inhibition ratio was 43.8%,29.6% and 18.9%,and the life extension ratio was 47.3%,17.9% and 6.3% in the transplanted Lewis lung cancer mice,respectively.Compared with that of the control,the apoptosis ratio was obviously increased in each group,and there was obviously induced S phase arrest in 25.0 mg/kg(P
