Abstract
Introduction: Green tea is a medicinal beverage extracted from the plant Camellia sinensis. Antioxidants that exist naturally can be extracted as pure compounds from their parent materials for nutraceutical and medicinal applications. The present study aims to assess the antioxidant activity of Zinc oxide-titanium dioxide nano-composites (ZnO-TiO2 NCs) containing green tea extract.
Materials and methods: The antioxidant activity was tested by Hydrogen Peroxide [H2O2] assay, Fluorescence recovery after photo-bleaching [FRAP] assay and 2, 2-diphenyl-1- picrylhydrazyl[DPPH] assay. All tests have shown very good results for the ZnO-TiO2 NCs.
Results: In this study, we present a straightforward, ecofriendly alternative for producing non-toxic zinc oxide and titanium oxide nano-composite material. This study could make a valuable contribution and create new opportunities in the market such as biological and pharmaceutical applications.
Conclusion: The in vitro tests concluded that the novel nanocomposite containing ZnO-TiO2 and green tea extract has good anti-oxidant properties and it is non-toxic to the biological systems.
期刊介绍:
Published since 1890 this journal originated as the Journal of the Straits Medical Association. With the formation of the Malaysian Medical Association (MMA), the Journal became the official organ, supervised by an editorial board. Some of the early Hon. Editors were Mr. H.M. McGladdery (1960 - 1964), Dr. A.A. Sandosham (1965 - 1977), Prof. Paul C.Y. Chen (1977 - 1987). It is a scientific journal, published quarterly and can be found in medical libraries in many parts of the world. The Journal also enjoys the status of being listed in the Index Medicus, the internationally accepted reference index of medical journals. The editorial columns often reflect the Association''s views and attitudes towards medical problems in the country. The MJM aims to be a peer reviewed scientific journal of the highest quality. We want to ensure that whatever data is published is true and any opinion expressed important to medical science. We believe being Malaysian is our unique niche; our priority will be for scientific knowledge about diseases found in Malaysia and for the practice of medicine in Malaysia. The MJM will archive knowledge about the changing pattern of human diseases and our endeavours to overcome them. It will also document how medicine develops as a profession in the nation. We will communicate and co-operate with other scientific journals in Malaysia. We seek articles that are of educational value to doctors. We will consider all unsolicited articles submitted to the journal and will commission distinguished Malaysians to write relevant review articles. We want to help doctors make better decisions and be good at judging the value of scientific data. We want to help doctors write better, to be articulate and precise.
