Medicinal plant is most exclusive sources of life saving drugs for the majority of the world population. Laboratory evaluations were made assess the study of primary metabolites of various plants in selected species Eupatorium triplinerve Vahl. During the present investigation comparative study of primary metabolites Carbohydrates, Protein, Ascorbic acid, Starch, Sugar, Chlorophyll, Carotenoids and Total phenol of genus Eupatorium triplinerve were undertaken for study and all the their chemical composition. The leaf highest amount of chlorophyll-a (4.95gm), chlorophyll-b (4.05gm), carotenoids (3.29gm),ascorbic acid (41.13gm/gdm), sugar (3.92gm/gdm), starch(5.89gm/gdm)protein (67.82µg/mg), total phenol (84.00gm/gdm). The root lowest amount of sugar (2.00gm/gdm), starch (3.15gm/gdm), protein (60.01µg/mg), ascorbic acid (43.09gm/gdm), total phenol (65.13gm/gdm).

The ferroelectric glycine phosphite single crystals have been grown from aqueous solution by both conventional and Sankaranarayanan-Ramasamy methods. The modified channelled spectrum method has been adopted for spectral dependence of optical birefringence studies over the wavelength range of 480-620 nm, which show that both the crystals exhibit relatively high birefringence values. The photoluminescence excitation studies were carried out for the grown crystals in a wide wavelength range between 300 nm and 600 nm at 224 K. The crystals were also subjected to scanning electron microscopy analysis in order to determine the ferroelectric domain pattern configuration.
