ISOLATION AND DEVELOPMENT OF AN HPLC METHOD FOR THE QUANTIFICATION OF A BIOMARKER IN THE ROOTS OF PAULLINIA PINNATA
An RP-HPLC method to be used to quantitate the amount of a biomarker in the roots of Paullinia pinnata was developed. The root bark was milled and extracted and the dry powder obtained taken through column chromatography (CC). The biomarker was then isolated. The melting point of the biomarker was determined and found to be 117-119 oC. A RP-HPLC method was successfully developed and used to quanti...
Man has been dependent on plants for the treatment and cure of different diseases since time immemorial. Plants have served not only as a source of food and shelter but also as a very important source of different “portions” used for the treatment and cure of diseases. These portions are herbal or plant based mixtures made by traditional healers; who are individuals having a knowledge of medic...
Zika virus infection is caused by the bite of an infected Aedes mosquito, usually causing rash, mild fever, conjunctivitis, and muscle pain. First time the virus was isolated in 1947 in the Zika forest in Uganda. It is transmitted to people through the bite of an infected Aedes mosquito. Symptoms are similar to those of dengue and chikungunya, which are transmitted by the same type of mosquito. Au...
ANTIDIABETIC ACTIVITY OF HYDROETHANOLIC LEAF EXTRACT OF GYMNEMA HIRSUTUM WIGHT & ARN IN STREPTOZOTOCIN-INDUCED DIABETIC RATS
The present study has investigated the hypoglycaemic effect of oral administration of 50% ethanolic leaf extract of G. hirsutum Wight & Arn in normal and Streptozotocin–induced diabetic rats. Albino Wistar rats (190 to 220 gm) were induced diabetic condition by administration of Streptozotocin (STZ) (55 mg/kg bw) intraperitoneally. 50% ethanolic extract of G. hirsutum Wight & Arn l...
IDENTIFICATION, METHOD DEVELOPMENT AND METHOD VALIDATION FOR THE PROCESS AND DEGRADATION IMPURITIES OF VARDENAFIL HCl BY RP-UPLC AND UPLC-TOF
This present work is on method development of assay and related substances of Vardenafil HCl and degradation of drug substance under acid, base hydrolysis and oxidation conditions. Identification of the impurities were done by the UPLC-TOF. Waters LCT Premier time of flight HRMS instrument with 5 ppm accuracy employed for degradation impurity identification. The validation of the method for its im...
The study evaluates the effect of di-n-butyl phthalate (DBP), a ubiquitous environmental contaminant, on epididymal antioxidant system of Wistar rats. Adult Wistar rats were orally administered DBP (500, 1000 and 1500 mg/ kg b.wt) for 7 days. Body weight increased significantly while caput and cauda epididymal weight decreased. Significant reduction in total protein concentration, lipid soluble an...
DEVELOPMENT AND OPTIMIZATION OF CHITOSAN-CA-PECTINATE BEADS OF AMORPHOUS CELECOXIB BY RESPONSE SURFACE METHODOLOGY
The aim of the present work was to develop a new microbeads system for colon-targeted delivery of celecoxib. The ternary system were develop using PVP (polyvinylpyrrolidone) and hydroxypropyl-β-cyclodextrin (HPB) to increase solubility of celecoxib. DSC and XRD results confirmed formation of amorphous celecoxib complex with HPB. Chitosan and pectin were used for the development of microbeads of...
Despite significant progress made in the treatment of infectious diseases, caused by bacteria and fungi, it remains a major worldwide health problem due to rapid development of resistance against the existing antimicrobial drugs. In the present investigation, a novel series of chalcones 2a–2h were synthesized by the clasein-schmidt condensation of various aldehydes with methyl ketone in the pres...
Aim: To evaluate safety and efficacy of diclofenac 75 mg/1ml (Dynapar AQ) administered as IV bolus versus diclofenac 75mg/3ml administered as IV infusion in patients with postoperative pain. Methods: 350 postoperative adult patientswere randomized to receive either treatment. Primary efficacy endpoints were time to onset of analgesia and postoperative pain intensity while secondary efficacy end...
LUPEOL PROTECTS ABNORMALITIES IN CELL SURFACE MOITIES DURING 7, 12-DIMETHYLBENZ[A]ANTHRACENE INDUCED HAMSTER BUCCAL POUCH CARCINOGENESIS
Lupeol, a pentacyclic triterpene, possesses diverse pharmacological and biochemical activities including anticancer and antioxidant effects. Abnormalities in the status of glycoconjugates and lipids in the cell results in malignant transformation. The aim of the present study was to investigate the protective effect of lupeol on cell surface glycoconjugates and lipids abnormalities during 7,12-dim...
