Spectroscopic Analysis of the Double Lined Eclipsing Binary {\alpha}Vir
  {\alpha}Vir is a well known double-lined spectroscopic binary with a B-type for both components. In the present paper we have analyzed a total of 90 spectra obtained through 1992-2000. Spectral analysis are based on two spectral lines H(alpha) and HeI 6678 belong to H(alpha) region. Radial velocity analysis have suggested low eccentric orbit (e=0.002) at inclination (i=81.89+-2.34) and with 4d.01422 period, semi-amplitude k1=100 km/s, mass ratio q=0.49+-0.05 and mass function f(m) =0.547. Using KOREL program for spectrum disentangling we have been able to decompose the spectrum of the system to its primary and secondary components. Synthetic spectral analysis of both the individual and disentangled spectra has been performed and yielded effective temperatures Teff= 25000+-250 K, surface gravities log g=3.75+-0.25 and projected rotational velocities (v sin i= 180+-5 km/s) for the primary, while for the secondary they are Teff = 17000+-250 K, log g = 4.0+-0.25.
