  Type II AGNs with polarimetric broad emission line provided strong evidence
for the orientation-based unified model for AGNs. We want to investigate
whether the polarimetric broad emission line in type II AGNs can be used to
calculate their central supermassive black hole (SMBH) masses, like that for
type I AGNs. We collected 12 type II AGNs with polarimetric broad emission line
width from the literatures, and calculated their central black hole masses from
the polarimetric broad line width and the isotropic \oiii luminosity. We also
calculate the mass from stellar velocity dispersion, $\sigma_*$, with the
$\mbh-\sigma_*$ relation.We find that: (1) the black hole masses derived from
the polarimetric broad line width is averagely larger than that from the $\mbh-
\sigma_*$ relation by about 0.6 dex, (2) If these type II AGNs follow
$\mbh-\sigma_*$ relation, we find that the random velocity can't not be omitted
and is comparable with the BLRs Keplerian velocity. It is consistent with the
scenery of large outflow from the accretion disk suggested by Yong et al.
