Quanttitative estimation of primary and secondary metabolites on flowers of caryota urens.L.

ABSTRACT

This paper describes the quantitative determination of primary and secondary metabolites present in the flowers of Caryota urens. The primary metabolites are the trace elements such as zinc, copper, boron and molybdenum quantified by AAS (Atomic Absorption Spectrometer) method and minerals such as sodium, potassium and calcium is quantified by flame photometer. Magnesium is quantified by the titrimetric method and nitrogen is quantified by kjeldhal’s method. Iron, Phosphorous, Boron, Molybdenum and Sulphur are quantified by Spectrocolorimetric method. The secondary metabolites are quantified by HPLC method (Alkaloids, terpenoids, liginins, tannins, glycosides, serpentines and saponins). The phenols are quantified by Folin’s Ciocalteau method and flavonoids by spectrophotometric method. This study indicates that the analysed species is a rich source of flavonoids, alkaloids and tannins etc..,
