   • Selon VINHOLES J (2017)

     Extrait Camellia sinensis, the most consumed & popular beverages worldwide, and Eugenia uniflora, a Brazilian native species, have been already confirmed to have beneficial effects in the treatment of diabetes mellitus. Objective: The aim of this study was to evaluate the inhibitory properties of individual & combined ethanolic extracts of the leaves of CS & EU over alpha-glucosidase, a key digestive enzyme used on the Type 2 diabetes mellitus (T2DM) control.

   • Selon Setiani LA (2018)

     Extrait Setiani LA et al, Activity of Antioxidant & Inhibitor α-Glucosidase Instant Granul Ethanol Tea Leaf Extract (Camellia sinensis) & Tea Benalu (Scurulla atropurpureea BL Dans), Jl OF SCI INNOVARE, 01 :01, 2018-Abstract. Tea leaves are plants that are widely spread especially in the area of West Java, while parasites are parasitic plants in tea trees that empirically have various properties such as antioxidants & anti diabetic.

   • Selon SHE J (2024)

     Extrait Less research has been conducted on the association between camellia oil's (CO) phenolic composition & antioxidant capability. In this study, the phenolic profile of CO & its connection to antioxidant capacity were examined utilizing a combination of widely-targeted phenolic metabolomics & multivariate statistical analysis.

   • Selon Deep-Kaur C (2011)

     Extrait The main antioxidant polyphenols present in Camellia sinensis (green tea) are known as epicatechins which function as anti-inflammatory or anticarcinogenic agents. The individual antioxidant activity obtained was 51.12±1.8% &combined antioxidant activity (ascorbic acid with extract) showed additive synergistic effect as compared to that of standard.

   • Selon Masitha FS (2019)

     Extrait Soursop Leaves (Annona muricata) & Tea Leaves (Camellia sinensis) are plants that contain flavonoids which are considered to act as antioxidants & can become chemopreventive agents. The second stage is to examine the antioxidant activity of the combination of ethanolic extract against free radical DPPH (1,1-diphenyl-2-pikrihidrazil).

   • Selon Ponte MP (2012)

     Extrait To evaluate the antitumor activity of alcoholic extracts of green tea (Camellia sinensis). Following euthanasia on the tenth day, the tumor, liver, kidneys and spleen were excised and weighed, and tumor volume and tumor growth inhibition were quantified.

   • Selon Esghaei M (2018)

     Extrait MATERIALS & METHODS: A hydroalcoholic extract of C sinensis young leaves was prepared by percolation & compared with Cisplatin as a known anticancer drug for effects on two cell lines: Caco-2, colon carcinoma cells, & mouse normal fibroblasts (L929). Camellia sinensis, whose leaves are used to produce green tea was evaluated for anticancer effects in cell culture.

   • Selon Masitha FS (2019)

     Extrait Soursop Leaves (Annona muricata) & Tea Leaves (Camellia sinensis) are plants that contain flavonoids which are considered to act as antioxidants & can become chemopreventive agents. Docking molecular test of acetogenin & catechin compounds at HER-& ER-α receptors which are biomarkers of breast cancer.

   • Selon Choi JH (2006)

     Extrait The methanol & ethanol extracts of precipitated cells (MEP, EEP) exhibited stronger inhibitory effects on the growth of tumor cell lines than the water extract of precipitated cells (WEP) or the supernatant. The objective of this study was to investigate the antitumor activity of suspension cultures of tea callus cells grown in the presence of different concentrations of the growth regulator 2,4-dichlorophenoxy acetic acid (2,4-D) with or without light irradiation.

   • Selon Thakur P (2013)

     Extrait The present study was conducted to evaluate the antimicrobial activity of aquo-ethanolic (1:1) extract of leaves of Camellia sinensis against Carbapenem Resistant E coli at preclinical level using peritonitis infection model in Sprague Dawley rats. Histopathological studies also presented symptoms of hemorrhage & glomerular damage with structural distortion in glomerular capillary loops of infected groups, which were later recovered in treated groups, indicating the nephroprotective potential of C sinensis PTRC-31911-A.

   • Selon EMERA MS (2025)

     Extrait The antimicrobial potentials of green tea (Camellia sinensis), rosemary (Rosmarinus officinalis) & ginger (Zingiber officinale) extracts against MDR Campylobacter isolates were assessed by the disk diffusion assay & broth microdilution technique. Methods: This study investigated the antimicrobial & antibiofilm activities of some herbal extracts against multidrug-resistant (MDR) Campylobacter species recovered from different sources using phenotypic & molecular techniques.
