| 1 | Intracellular biosynthesis of Au and Ag nanoparticles using ethanolic extract of Brassica oleracea L. and studies on their physicochemical and biological properties显示文摘In this present study, we reported broccoli(Brassica oleracea L.) as a potential candidate for the synthesis of gold and silver nanoparticles(NPs) in green chemistry method. The synthesized metal nanoparticles are evaluated their antimicrobial efficacy against different human pathogenic organisms. The physico-chemical properties of gold nanoparticles were analyzed using different analytical techniques such as a UV–Vis spectrophotometer, Field Emission Scanning Electron Microscopy, energy dispersive X-ray spectroscopy, X-ray diffraction and a Fourier Transform Infrared spectrophotometer. In addition, gold and silver NP antimicrobial efficacy was checked by disc diffusion assay. UV–Vis color intensity of the nanoparticles was shown at 540 and 450 nm for gold and silver nanoparticles respectively. Higher magnification of the Field Emission Scanning Electron Microscopy image shows the variable morphology of the gold nanoparticles such as spherical, rod and triangular shapes and silver nanoparticles were seen in spherical shapes. The average spherical size of the particles was observed in 24–38 nm for gold and 30–45 nm for silver NPs. X-ray diffraction pattern confirmed the presence of gold nanoparticles and silver nanoparticles which were crystalline in nature. Additionally,the functional metabolites were identified by the Fourier Transform Infrared spectroscopy. IR spectra revealed phenols, alcohols, aldehydes(sugar moieties), vitamins and proteins are present in the broccoli extract which are accountable to synthesize the nanoparticles. The synthesized gold and silver NPs inhibited the growth of the tested bacterial and fungal pathogens at the concentration of 50 μg/m L respectively. In addition, broccoli mediated gold and silver nanoparticles have shown potent antimicrobial activity against human pathogens. | Palaniselvam Kuppusamy Solachuddin J.A.Ichwan Narasimha Reddy Parine Mashitah M.Yusoff Gaanty Pragas Maniam Natanamurugaraj Govindan | 2015 | Journal of Environmental Sciences2015，27，3： | 3 |
| 2 | Nutraceuticals as potential therapeutic agents for colon cancer: a review显示文摘Colon cancer is a world-wide health problem and the second-most dangerous type of cancer,affecting both men and women.The modern diet and lifestyles,with high meat consumption and excessive alcohol use,along with limited physical activity has led to an increasing mortality rate for colon cancer worldwide.As a result,there is a need to develop novel and environmentally benign drug therapies for colon cancer.Currently,nutraceuticals play an increasingly important role in the treatment of various chronic diseases such as colon cancer,diabetes and Alzheimer's disease.Nutraceuticals are derived from various natural sources such as medicinal plants,marine organisms,vegetables and fruits.Nutraceuticals have shown the potential to reduce the risk of colon cancer and slow its progression.These dietary substances target different molecular aspects of colon cancer development.Accordingly,this review briefly discusses the medicinal importance of nutraceuticals and their ability to reduce the risk of colorectal carcinogenesis. | Palaniselvam Kuppusamy Mashitah M.Yusoff Gaanty Pragas Maniam Solachuddin Jauhari Arief Ichwan Ilavenil Soundharrajan Natanamurugaraj Govindan | 2014 | Acta Pharmaceutica Sinica B2014，4，3： | 2 |

| 7 | 以对二甲苯氧化为对苯二甲酸为例简要综述一级C–H键活化(英文)显示文摘The oxidation of para‐xylene to terephthalic acid has been commercialised as the AMOCO process(Co/Mn/Br) that uses a homogeneous catalyst of cobalt and manganese together with a corrosive bromide compound as a promoter. This process is conducted in acidic medium at a high tempera‐ture(175–225 °C). Concerns over environmental and safety issues have driven studies to find mild‐er oxidation reactions of para‐xylene. This review discussed past and current progress in the oxida‐tion of para‐xylene process. The discussion concentrates on the approach of green chemistry in‐cluding(1) using heterogeneous catalysts with promising high selectivity and mild reaction condi‐tion,(2) application of carbon dioxide as a co‐oxidant, and(3) application of alternative promoters. The optimisation of para‐xylene oxidation was also outlined. | Nor Aqilah Mohd Fadzil Mohd Hasbi Ab.Rahim Gaanty Pragas Maniam | 2014 | 催化学报2014，35，10： | 1 |
