A simple and rapid reversed phase-high performance liquid chromatographic (RP-HPLC) method was proposed for simultaneous determination of imipramine hydrochloride and diazepam in pharmaceutical formulations. Elution was done utilizing methanol: water: 0.1%m sodium acetate (30:50:20 v/v/v) mobile phase with Chromosil C18 column in isocratic mode, at a flow rate of 1.0 ml/minute and detection wavelength of 243 nm. The measured retention times for imipramine hydrochloride and diazepam were 3.33±0.02

Phlomis Younghusbandii Mukerjee is a perennial herb (family Labiatae) and grows wildly in Qinghai-Tibet Plateau of China. It has been widely used to treat colds, coughs, sores ulceration, rheumatoid arthritis, pneumonia, bronchitis and other diseases for thousands years. In this paper, 5 iridoid glycosides (sesamoside, shanzhiside methylester, 7, 8-dehydropenstemoside, penstemoside and 8-O-acetylshanzhiside methylester) and 3 phenylethanoid glycosides (acteoside, alyssonoside, and isoacteoside) in

developing sensitive, simple, and rapid method for determination of DXM has been become an important target in control pharmaceutical dosage form. Therefore wide range of analytical methods for quantitation of DXM have been developed such as, high performance liquid Chromatography(HPLC) (Abdel-Moety, Al-Deeb, and Khattab 1995, Tedesco et al. 2013, Eichhold et al. 1997, Hoskins, Shenfield, and Gross 1997) (Abdel-Moety, Al-Deeb, and Khattab 1995, Tedesco et al. 2013, Eichhold et al. 1997, Hoskins, Shenfield

original values.Various methods have been discussed in the literature for determination of Famotidine and Flurbiprofen tablets like spectrophotometric analysis [2], potentiometric [9], Electrochemical, Flow injection analysis FIA. Among them, High performance liquid chromatography is precise, specific, rapid and simple. There is a need of such HPLC methods for detection of two drugs in a single dosage form.The object of this study was to formulate the

modern life, used to protect everything from flower gardens to agricultural crops from specific pests (Saravi & Shokrzadeh, 2011) Pesticides are considered a vital component of modern farming, playing a major role in maintaining high agricultural productivity. Consequently, in high-input intensive agricultural production systems, the widespread use of pesticides to manage pests has emerged as a dominant feature (Saravi & Shokrzadeh, 2011) Pesticides comprise a large number of substances that belong to

Rooibos tea is also an alternative health beverage because it contains no harmful stimulants and no caffeine. The health properties are mainly due to the low tannin content and the high levels of minerals and the free-radical capturing properties of the unique flavonoids; C-glucoside dihydrocharcones asphalathin and nothofagin. In addition to the antispasmodic activity the rooibos tea also has antioxidant, anti-mutagenic and anti-aging

The structures of LPSF-33, LPSF-34 and LPSF-35, including both E and Z isomers, were drew using the SPARTAN 08' program [20] and the optimization of each structure was carried out using the RM1 [21] method, available as part of the SPARTAN 08’ program, using internal default settings for convergence criteria. Docking analysis was carried out on Peroxisome Proliferator Activated Receptor (PPAR) Gamma (PDB code: 2PRG). The chosen PPAR structure has been used in another work involving an antidiabetic

High Performance Liquid Chromatography, abbreviated HPLC, is a type of Chromatography that uses liquids to separate mixtures. Unlike other chromatography methods, HPLC uses liquid mixtures for both the mobile and the stationary phases. A syringe is used to inject a small amount of the mixture we’re looking to separate into the HPLC column, and the mobile phase acts as the transporter. The mobile phase contains a carrier liquid that is comprised of all of the dissolved substances that are of interest

phase (mobile phase). During the chromatographic development process, the mixture to be separated is distributed between the stationary and mobile phases. (Spangenberg Bernd et al 2011). It is mostly used because of its simplicity, relatively low cost, high sensitivity and relatively fast speed of separation. TLC also functions on the same principle as all other chromatography techniques. A compound has different affinities for the mobile and stationary phases, and this affects the speed at which it migrates
