The leaves of Acacia nilotica (L.) Delile was extracted with methanol and aqueous medium and studied for in vitro antimicrobial property. The methanol extract was found to be most active against all the bacterial species tested except S.aureus. Active methanol extract was further studied for HPTLC fingerprint and by phytochemical analysis. HPTLC analysis confirmed segregation of four individual...
Content fingerprinting and digital watermarking are techniques that are used for content protection and distribution monitoring. Over the past few years, both techniques have been well studied and their shortcomings understood. Recently, a new content fingerprinting scheme called active content fingerprinting was introduced to overcome these shortcomings. Active content fingerprinting aims to m...
Abstract Pressurized planar electrochromatography (PPEC) of dansyl (DNS) derivatives amino acids in normal- and reversed-phase systems is presented. The results have been obtained for mobile phases with different acetonitrile (ACN) concentrations (0–85%). data show differences separation selectivity between high-performance thin-layer chromatography (HPTLC) PPEC systems. These originate from th...
background and objectives: rutin, quercetin and liquiritin arepolyphenol flavonoids which have shown anti-inflammatory, antihepatotoxic, antiulcer, antiallergic, antidiabetic, antiviral and antioxidant activities. they are found in many herbal plants, one of them is cocculus hirsutus. the objective of this research was to develop and validate a new, accurate, precise and economic hptlc method ...
BACKGROUND: Colibacillosis is one of the most economically important diseases of poultry worldwide. OBJECTIVES: This study was conducted to examine the clonal relatedness and typing of 95 avian Escherichia coli isolates by ERIC-PCR. METHODS: Sixty-three E. coli isolates from two common manifestations of colibacillosis (yolk sac infection and colisepticemia) and 32 isolates from feces of apparen...
Context Quantitative standardization of plant-based products is challenging albeit essential to maintain their quality. Aims This study aims to develop and validate high-performance thin-layer chromatography (HPTLC) method for the simultaneous determination of rutin (Ru), quercetin (Qu), and gallic acid (Ga) from Psidium guajava Linn. (PG) and Aegle marmelos (L.) Correa. (AM) and correlate wi...
Abstract Bamboo tableware became popular as ecofriendly material. However, industrial products made of bamboo-melamine–formaldehyde resin material are not biodegradable. In addition, harmful compounds were detected if such consumer articles used with hot drinks or food, and risk assessment found that maximum daily dosages melamine formaldehyde exceeded. High-performance thin-layer chromatograph...
We analyze and demonstrate the feasibility and superiority of linear optical single-qubit fingerprinting over its classical counterpart. For one-qubit fingerprinting of two-bit messages, we prepare "tetrahedral" qubit states experimentally and show that they meet the requirements for quantum fingerprinting to exceed the classical capability. We prove that shared entanglement permits 100% reliab...
in the developing countries of tropical regions, mycotic infections are common cause of skin diseases.the use of medicinal plants in the treatment of skin diseases including mycotic infections is an age-old practice in many parts of the world. the drugs used against dermatophytosis have several side effects, but limited efficacy. there is therefore a distinct need for discovery of new, safer an...
Aim: To identify the hypericin content in Hypericum gaitii Haines through HPTLC & FTIR, an endangered medicinal plant and potential for curing many diseases like cancer, AIDS, tumour etc. Methods: Methanolic extract of leaves derived from in vitro raised plants were used in the mobile phase of Toluene: Ethyl acetate: Formic acid (10:8:3) and scanned under UV at 254nm and 366 nm and under visibl...
