“…A non fluorescent compound may fluoresce if mixed with impurities that are fluorescent. The fluorescent method is adequately sensitive and enables the precise and accurate determination of the analyze over a satisfactory concentration range without several time consuming dilution steps prior to analysis of pharmaceutical samples 14 . Fluorescence analysis of the leaf powder of Cynodon dactylon (L.) Pers.…”

From ancient time, plants serve as vast source for varied phytoconstituents exhibiting varied pharmacological property. Identifying such potential plants is of significance in medicine. So it becomes necessary to study the pharmacognostic characteristic and physicochemical parameters of the plant before they are use in the field of research and also in pharmaceutical formulations. Moreover it also helps in distinction from other allied species and adulterants, guarantee the safe use of quality products. In this connection, the pharmacognostical characteristics of the leaf of the Cynodon dactylon (L.) Pers. was examined. The macro and microscopical characteristics like, vein islet numbers, palisade ratio, stomatal index (upper and lower surfaces of the leaf) etc. were studied. Physicochemical parameters evaluated include ash values, extractive values and loss on drying. These findings will be helpful towards establishing pharmacognostic and physiocochemical standards on identification, purity, quality and classification of the plant, which is gaining relevance in plant drug research.

“…BI has actually played an outstanding role in the improvement of cellular assays. [45] Hodder and Ruzicka [46] introduced in 1999 a novel application of SI-BI by using beads as micro-carriers of living cells to measure elevation of intracellular calcium. High density of cells could be trapped in the small inner volume of a jet ring cell which was placed above a fluorescence microscope objective lens.…”

. (2008). Recent developments in automatic solid-phase extraction with renewable surfaces exploiting flow-based approaches. TRAC -Trends in Analytical Chemistry, 27(9), 749-761. DOI: 10.1016749-761. DOI: 10. /j.trac.2008 TrAC MS:08-00052-REVISED Abstract: Solid-phase extraction (SPE) has been consolidated as the most versatile sample processing method for removal of interfering species and/or analyte enrichment. Although significant advances have been conducted over the past two decades for automation of the entire analytical protocol involving SPE via flow injection approaches, on-line SPE assays performed in a permanent mode lack sufficient reliability as a consequence of the progressive tighter packing of the bead reactor, contamination of the solid surfaces and potential leakage of functional moieties. This article overviews the current state-of-the-art of an appealing tool for overcoming the above shortcomings, the so-called bead injection (BI) analysis, based on automated renewal of the sorbent material per assay exploiting the various generations of flow injection analysis. It addresses novel instrumental developments for implementation of BI and a number of alternatives for on-line chemical derivatization reactions and pinpoints the most common instrumental detection techniques utilised. Relevant environmental and bioanalytical applications reported within the past few years are presented and discussed in detail.
