“…Both of them showed almost the same FT-Raman spectra with a broad peak having an appreciable peak at about 850 cm -1 . Thus, ghost cells and keratinocytes showed similar Raman spectra, suggesting both of ghost cells of CCOT and keratinocytes have similar structure as observed in TEM study 10) .…”

“…Quercetin is a recognized antioxidant and has been studied for its gastro-protective effects, inhibition of carcinogenicity either alone or in combination with chemotherapeutic agents, reducing risk of cataract. Again, the ability of quercetin to inhibit inflammatory leukotriene production may be a key to its beneficial impacts 7,8 .…”

The curative parts of medicinal plants are not simply its woody stem or its leaves but the number of chemical compounds (phytoconstituents) it produces and uses for its own growth like flavonoids, alkaloids, gum, mucilage, protein, carbohydrate etc. The genus Phyllanthus is widely used in medicine but still lot of work left to explore this genus. So the species, Phyllanthus emblica which is widely used in Indian traditional system are selected for various screening. The mentioned plant materials are rich source of polyphenolic compounds and some typical type of polyphenolic are responsible for various pharmacological activities. The isolation and characterization of Phytoconstituents was done from the alcoholic extract by the chromatographic method. The structure of the isolated compound was established on the basis of physical, chemical test and spectroscopic evidences (IR, UV, 1HNMR, MS). A flavonoidal structure was isolated from the alcoholic extract of the plant. The yellow colored compound which solubilizes in methanol, ethanol and water having m.p. 315 o C and Rf value 0.19 in mobile phase Isopropanol: formic acid: water (2:5:5) was identified by the various spectroscopical methods. So from this study it is concluded that isolated compound may be quercetin which is responsible for various pharmacological activities of the plants.

the use of chemometric methods in the analysis of Raman and IR spectra of dyes has opened new possibilities in the areas previously reserved only for chromatographic methods or conventional uv-vis studies. this chapter is focused on the analysis of natural dyes, especially carotenoids, flavonoids, anthraquinones and indigoids presented in biological samples e.g. plants or food. the discussed chemometric methods are implemented both in the qualitative and quantitative determination of colorants with the techniques of vibrational spectroscopy
