Abstract In this work, optical emission spectroscopy (OES) was used to estimate the parameters of plasma electron temperature (Te), electron density (ne), plasma frequency (fp), Debye length (λD), and Debye number (ND). Understanding how an energy pulsed laser affects these variables is also important. Irradiation of pure cadmium using an Nd: YAG laser pulse with a wavelength(1064)nm and energy ranging from (200-600)millijoules, of frequency (6) Hz. The spectrum of laser-induced plasma was detected under atmospheric pressure. It was discovered that when the energy of the laser pulse rises, the intensity of the CdI and CdII lines increases.

Scoparia dulcis Linn has been widely reported to have pharmacological uses arising from its wide spread uses. The different extracts were prepared by successive extraction with petroleum ether, chloroform, ethanol and water using soxhlet distillation method. Phytochemical analysis of plant extract revealed the presence of alkaloids, carbohydrates, glycoside, tannins, starch etc.Thin layer chromatography and Gas chromatography-mass spectrometric analysis revealed the presence of different components in the plant extract. Among the 50 components obtained, 10 important organic compounds were analyzed. All these compounds are found to be having some medicinal application.UV visible spectroscopic analysis of extract of Scoparia dulcis reported four chromatogram figures which showed prominent peaks having maximum absorption of 666 nm corresponded to wavelength of methylene blue and brilliant blue. FTIR spectroscopic analysis reveals the presence of important functional groups like-OH,-NO2,-SO3,-SH, -COOH, NH2, R-X etc. Antibacterial activity of petroleum ether, chloroform, and ethanol and water extracts of stems and leaves of Scoparia dulcis reveals that chloroform and ethanol extracts shows maximum resistance against Staphylococcus while ethanol and aqueous extracts showed maximum resistance against Klebsiela pneumonia.The exciting fact came out of the study is that water extract of Scoparia dulcis showed great potential to dissolve the Calcium oxalate crystals ie, the plant extract shows invitro antilithiatic activity for kidney stones. Thus Scoparia dulcis act as a source of different valuable organic compounds that are having medicinal applications and have a beneficial effect on kidney stone problem.
