The antibacterial activities of water extracts of the three major parts of the date palm fruit were compared against Eschereshia coli; Klebsiella pneumonia; Salmonella enteritidis; Pseudomonas aeruginosa; Staphylococcus aureus using the agar well diffusion method. Endocarp extract showed a wide range of activity against all Gram negative bacteria while it exhibited a low activity against Gram positive bacteria.The date tissue and endocarp didn’t show any activity against Klebsiella pneumoniae with a low or no activity against Pseudomonas aeruguinosa. Date tissue extract alone didn’t exhibit any activity against Klebsiella pneumoniae and Pseudomonas aeruguinosa. All types of extract were active against Escherichia coli. A consistently lower susceptibility of Klebsiella pneumonia and P. aeruginosa indicated its capability for developing resistance against various antibacterial substances. Antibacterial activities displayed by all extracts especially the endocarp also signified their remarkable potential for exploration of effective natural antibacterial agents against common pathogenic...

Four wild plant species (Chrysthanthemum cornarium, Capparis spinosa, Carthamus lanatus, Haplophyllum tuberculatum) were investigated for their antioxidant activity, phenolic and flavonoid contents of their methanolic extracts. The antioxidant activity of the extracts was assessed their free radical scavenging properties using DPPH. Total phenolics and total flavonoids were detected by spectrophotometric and HPLC methods. The HPLC analysis compared with 14 reference standard phenolic compounds, results confirmed that gallic acid , chlorogenic acid, caffeic acid, 2,5- dihydroxy benzoic acid, and catechin were detected in the four methanolic plant extracts. HPLC chromatograms of the plant extracts showed that there was noticeable valuation in the distribution of phenolic compounds in the four studied species. Six bacterial strains were used in this study, three Gram-positive and three Gram-negative. Concerning with antimicrobial activity, results showed that plant extracts of the studied species are a great source of phenolic compounds and represent the highest antibacterial activity against Gram-positive and negative bacteria. Results revealed that extracts represents the highest antibacterial activity against Gram-positive and negative bacteria and...

Many infectious diseases are known to be treated with herbal remedies throughout the history of mankind. Even today, plant materials continue to play a major role in primary health care as therapeutic remedies in many developing countries. Traditional system of medicine is found to have utilities as many accounts. Due to population rise adequate supply of drug and high cost of treatment in side effect along with drug resistance has been encountered in synthetic drugs, which has lead to an elevated emphasis for the use of plants to treat human diseases. A major part of the total population in developing countries still uses traditional folk medicine for different diseases obtained from plant resources. Due to the indiscriminate use of antimicrobial drugs, the emergency of human pathogenic microorganism’s resistance has been increased. According to WHO, as many as 80% of world’s population living in rural areas rely on herbal traditional medicines as their primary healthcare, the properties and uses of medicinal plants are interestingly growing. Thus, due to prevalence of...

Increased production of reactive oxygen species plays important role in pathogenesis of chronic fluoride toxicity resulting from prolonged exposure to fluoride. Oral (NaF) fluoride administration to rats at 20 mg/kg b.w./day for 30 days resulted in elevation in MDA, free amino acid N2, NO level and decreased activities of SOD, GPx, CAT, GR and reduced non enzymatic antioxidant like GSH. Significant alteration in protein and nucleic acid metabolism in discrete brain regions was observed associated with altered activities of proteolytic and transaminase enzymes in treated animals. Neanotis wightiana is traditionally used by local people of Tripura for brain and liver disorders. 3α-hydroxy olean-12-en-27-oic acid isolated from the plant was administered to rats at a dose of 5 mg/kg b.w./day orally for the last 14 days of fluoride exposure in order to elucidate the antioxidative role of this triterpenoid compound in brain protein and nucleic acid metabolism during toxic insult. The present study indicates that the compound appreciably prevented NaF-induced changes in above mentioned parameters in rat brain by antagonizing...

Coronary artery disease (CAD) is the major cause of mortality and morbidity worldwide. The incident of CAD is rising and they are predicted to be the biggest causes of death by 2020 in India. Therefore, the aim of the present study was to assess the association of oxidative stress, antioxidant enzyme and lipid status parameters in CAD patients and to compare the results age- sex matched healthy control in our community. Three hundred participants were enrolled for the present study, with their ages ranging from 40 to 60 years from Era’s Lucknow Medical College & Hospital, Lucknow. Out of which one hundred fifty were clinically new diagnosed case of coronary artery disease like angina pectoris and Myocardial infarction (MI), remaining one hundred fifty were healthy controls. These participants were investigated for serum lipid profile i.e. total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL), very low density lipoprotein (VLDL). High density lipoprotein (HDL) along with blood levels of TBARS and some antioxidant enzyme namely Catalase (CAT), Superoxide dismutase (SOD),...
