INTRODUCTION Bhasma, an Ayurvedic metallo-mineral preparation, is claimed to be biologically produced nanoparticles. Rajata (silver) is a noble metal known for its antimicrobial activity. Rajata Bhasma (RB) is expected to be composed of nanoparticles. With all these facts in place, this study was conducted to evaluate RB for the presence of silver nanoparticle (SNP) and its antimicrobial effect...

eperisone hydrochloride is a skeletal muscle relaxant and paracetamol is cyclooxygenase inhibitor. these drugs in combination are used as antispasmodics. a simple, specific, precise and accurate method was developed, namely reverse phase high performance liquid chromatography for simultaneous estimation of eperisone hydrochloride and paracetamol in tablet dosage form. in rp-hplc method separati...

a rapid, specific and accurate proton quantitative nuclear magnetic resonance spectroscopic (1h qnmr) and also a reversed phase derivatization hplc method have been developed to quantify a toxic, uv-visible inactive and non-volatile impurity n,n-dimethylamine hydrochloride (dma∙hcl) in metformin hydrochloride (mf∙hcl), an active pharmaceutical ingradient. the method is based on proton quantitat...
