Cu/CNT > Cu-Zn/CNT, which related mainly to the chemical composition of Zn/CNT composite. Zn/CNT composite showed the highest degradation efficiency among the prepared composites, which achieved 97.7% after 70 minutes under visible light irradiation. The mechanism of the photocatalytic degradation of congo red dye under visible light irradiation was discussed.]]>

100 μg/mL). In addition, the extract exhibited reasonable antibacterial activity against Staphylococcus aureus, Bacillus cereus, and Escherichia coli with MIC values of (200, 500 and 500 mg/ml), respectively without the detection of any activity against Salmonella typhimurium, Candida albicans and Aspergillus brasiliensis. The phytochemical study revealed the identification of eleven polyphenolic compounds representing 80.8 % of the total area; the major compounds were chlorogenic acid (40.8 %), gallic acid (11.1%), catechin (8.2%) and taxifolin (7.6 %). Moreover, gallic acid, kaempeferol and catechin were isolated and identified for the first time from the ethyl acetate extract. In addition, the plant extract is found to be rich in natural pigments (total carotenoids = 864.64 g/100g). In conclusion, the current study revealed that ethyl acetate extract of Pleiogynium timorense leaves is rich with polyphenolic compounds, which play a vital role in the plant bioactivities.]]>

The invivo cytotoxicity of the complexes showed that, the complexes have no side effects after six weeks was confirmed by clinical and histopathological studies. The results augur well for breast cancer treatment.]]>
