A reverse-phase liquid chromatographic (RP-HPLC) method was developed for the determinations of loperamide hydrochloride and norfloxacin in their marketed formulation and bulk. The separation was carried out using mobile phase of triethylamine and acetonitrile (50:50%) with pH 4.The pH adjusted with orthophosphoric acid. The column used was Capcell pack C18 Column (250mn x 4.6mm, 5mm) and flow rate of 1 ml/min. Detection carried out at 213 nm. The retention time loperamide hydrochloride 5.6 and norfloxacin were found to be 2.1 min respectively. Developed method was validated according to ICH guideline. Linearity was observed at concentration rang of 2-6 mg/ml for loperamide hydrochloride and 200-600 mg/ml for norfloxacin. The regression equation were found to be Y=48615x-435565 and Y=72087x-14016 the correlation coefficient (r2) 0.9996 and 0.9988 norfloxacin and loperamide hydrochloride respectively. The percentage RSD for the method precision was found to be less than 2%. The accuracy is found in 98-101 %. The proposed method is precise, accurate, selective and rapid for simultaneous determination of loperamide hydrochloride and...

Azima tetracantha is a small flowering shrub belongs to salvadoraceae family and commonly known as mulluchangu or mulsangu in Tamil. It is an best known medicinal plant ,which have a central role in the treatment of disease from pre historical period. From the plant lot of phytochemicals has been reported such as alkaloids, steroids ,tannins, terpenoids, flavonoids, glycosides, phenols etc and also possesses activities such as antioxidant, antifungal, antibacterial , hepatoprotective, antidiabetic and antihyperlipidemic etc .In the present study preliminary evaluation and isolation of an active pharmacological compound euphol was obtained from the chloroform extract of the leaves of Azima tetracantha was carried out. The compound euphol is a tetracyclic triterpene alcohol which produces antinociceptive effects in inflammatory and neuropathic pain. The compound was isolated by column chromatography and characterized by chemical test, TLC, FTIR, NMR, C 13 NMR spectrum. In future it may be a promising molecule for the management of neuropathic...

The Wheat, Maize and Cotton are the major crops in the agriculture field specially in Maharashtra, India. So for better productivity this study aims to prepare steam soluble aroma compounds called hydrosols. Hydrosols of different plant species (Ipomea carnea Leaves and Flowers, Lantana Camera Leaves) were prepared by steam distillation method. The purpose of this study was to determine the effect on the growth of Wheat, Maize and Cotton crops by using Ipomea carnea leaves and flowers and Lantena camera leaves. In this study the wheat, maize and cotton crops were germinated in different pots and continuous dosing of hydrosol was applied with fixed quantity and result was observed after...

Advances in nanoparticulate frameworks for enhanced medication conveyance show an extraordinary potential for the organization of urgent dynamic particles. The fundamental motivation behind creating elective medication conveyance advances is to build proficiency of medication conveyance. Pterospermum acerifolium is normal plant in India is viewed as carminative, stimulant and emmenagogue. The point of this study was to figure another conveyance framework for impacts of neurobehavioural by the joining of concentrate of Pterospermum acerifolium into strong lipid nanoparticles SLN. SLN plans were set up by ethanolic extricate implanted lipid layer was softened by warming at 5°C above liquefying purpose of the lipid. After that, SLNs were sifted and dried .Shape and surface morphology of the strong lipid nanoparticles were envisioned by filtering electron microscopy (SEM).Particle Size and Size Distribution were dictated by Photon relationship spectroscopy (PCS). The change of molecule charge was considered by Zeta Potential (ZP) estimations. The CNS action was examined in a few test models for Epilepsy i.e. Limit Pentylenetetrazole prompted seizure, Models for anxiolytic study i.e. Hoisted...

Candesartan cilexetil, a prodrug is a racemic mixture containing one chiral center at the cyclohexyloxy-carbonyloxy- ethyl ester group. It is soluble in dimethyl formamide, acetone, methanol, 0.1 N sodium hydroxide solution and insoluble in water. Objective of the present study was to develop a simple, sensitive, accurate, precise and rapid derivative spectrophotometric bioanalytical method for the estimation of candesartan in pure form. For the estimation of candesartan, solvent system employed was absolute methanol and wavelength of detection (λdet) was 268.8 nm for first order derivative spectroscopy. The linearity was obtained in the range 2 – 10 µg/ml with a regression coefficient of R2 = 1. The limit of detection is 0.99 µg/ml and limit of quantification was found to be 3.1 µg/ml. Obtained results showed that there is minimum intraday and inter day variation. The developed method was validated and recovery studies were also carried out. Sample recovery using the above method was in good agreement with their respective labeled claims, thus suggesting the validity of the method and...
