Peach (Prunus persica L.), being a potential source of bioactive compounds, has been demonstrated to have medicinal benefits. In this study variation minerals and antioxidant characteristics (total phenolic contents, total flavonoid reducing power, inhibition peroxidation using linoleic acid system DPPH free radical scavenging activity) between peel pulp parts different peach varieties, namely Golden, Shireen, Shahpasand were investigated. The extracts, derived from the varieties analyzed,...

Objective: Agro-industrial residues are primarily composed of complex polysaccharides that strengthen microbial growth for the production industrially important enzymes. For industrial use, pectinases can be produced from several agricultural pectin-containing wastes like orange peel. The selection cheap source benefits enzymes in term to costs-effective production. Methods: indigenously pectinase was purified homogeneity level using a combination ammonium sulphate precipitation and Sephadex...

Current study was planned to explore the therapeutic response of different doses hydroethanolic extract Epimedium grandiflorum leaves in male albino rats. Phytochemical analysis, HPLC and FTIR spectroscopy results revealed presence wide range phenolic compounds functional groups, respectively. Further, not induced significant hemolysis (7.56 ± 1.297%) against PBS (3.65 0.35%) as negative control; while have clot lysis (44 5.2%) potential, exhibited DPPH (78.87 5.427%) scavenging, H 2 O...

New, cost-effective source materials are being sought to enable the development of essential oils for potential use in pharmaceutical and commercial applications. The present study was aimed at investigating such features Cupressus sempervirens, which despite its exotic legendary attributes has been almost ignored up until now. Gas liquid chromatography (GLC) used determine various physico-chemical composition parameters (specific gravity, refractive index, acid ester values profile)...

There is growing interest in the development of novel nanomaterials with potential antimicrobial activity and lesser toxicity. In current research work, Mn 0.5 Zn Fe 2 O 4 nanoparticles were synthesized via a coprecipitation cum laser ablation technique yielding fine spinal structured material. The nanomaterial was structurally characterized by X‐ray diffraction which confirmed formation crystalline nature 0.50 nanomaterial. crystallite size determined Debye‐Scherrer’s formula found to be...

The study was carried out to determine, by PCR-RFLP, the magnitude of drug resistance in Mycobacterium tuberculosis. on 221 random sputum samples collected from patients and 120 suspected cases resistance. Genetic variation drug-resistant strains evaluated through PCR-RFLP for isoniazid, ethambutol, streptomycin, ofloxacin. Out 341 patients, 91.5% were confirmed as M. tuberculosis complex infected basis PCR. revealed 8.2% cases, while 73.3% those with found resistant. Among isolates, 56.1%...

Tuberculosis (TB) caused by Mycobacterium tuberculosis (MTB) is a chronic bacterial infection affecting many organs of the body particularly lungs. Another organ seriously affected TB hematopoietic system. patients co-infected with other disorders are more prone to death than alone. This study was aimed investigate variations in hematological profile pulmonary (PTB) infectious and metabolic disorders. The population (n = 366) include PTB (positive control) hepatitis C virus (HCV) infection,...
