ABSTRACT

Objective:To explore the quantitative estimation of biomarkers gallic acid and berberine in polyherbal formulation Entoban syrup. Methods: High performance thin layer chromatography was performed to evaluate the presence of gallic acid and berberine employing toluene:ethyl acetate:formic acid:methanol 12:9:4:0.5 (v/v/v/v) and ethanol: water: formic acid 90:9:1 (v/v/v), as a mobile phase respectively. Results:The Rf values (0.58) for gallic acid and (0.76) for berberine in both sample and reference standard were found comparable under UV light at 273 nm and 366 nm respectively. The high performance thin layer chromatography method developed for quantization was simple, accurate and specific. Conclusions: The present standardization provides specific and accurate tool to develop qualifications for identity, transparency and reproducibility of biomarkers in Entoban syrup.

ABSTRACT

Objectives: To study the morpho-anatomy of the aerial parts of Rivea hypocrateriformi (Convolvulaceae) to increase the knowledge and standardization parameters of these plants and its family. Methods: Morpho-anatomical studies of aerial parts of have been carried out by free hand. The different types of histochemical tests were performed for the identification of micro-chemical by using staining reagents. Preliminary phytochemical and quantitative estimation has been determined along with HPTLC fingerprinting. CAMAG HPTLC system equipped with Linomat V applicator, TLC scanner 3, Reprostar 3 and WIN CATS-4 software was used for fingerprinting. Results: The morpho-anatomical structure of plant revealed the presence of thick wall collenchyma cell and parenchyma cells along with spharaphides and columnar palisade cells. Presense of numerous covering trichomes, parasitic stomata, oval shaped vascular bundles and calcium oxalate crystals were observed. In powder microscopy lignified xylem vessels, and covering trichomes were clearly seen. Physicochemical parameters, ash value, inorganic elements, moisture content and extractive value were determined to develop the stringent pharmacognostic standards. Qualitative standardization and HPTLC fingerprinting of phytochemical revealed the presense of various plant secondary metabolites. Conclusions:These findings will be useful in establishing pharmacognostic and phytochemical standards for identification, as well as assessment of purity and quality of this plant, which definitely gaining the relevance in plant drug research and establishment of plant monograph.

ABSTRACT

Piperine, a characterizing compound present in fruits of Piper nigrum and Piper longum used as bioavailability enhancer. Ingredients of antioxidant, anti-inflammatory activity has been extracted using soxhlet and supercritical fluid extraction technique. It was isolated using column chromatography. Characterization of compound was done by spectroscopic technique. A simple, rapid, accurate and specific HPTLC method developed and validated. The method proposed can be used for the routine analysis of both P.nigrum and P.longum fruit material and its formulations.
