Abstract

The oral bioavailability of vasicine (1) was investigated in hard gelatin capsules of lyophilized Vasa Swaras (aqueous extract of Adhatoda vasica Nees.,Fam.: Acanthaceae) The rat pharmacokinetic profile of lyophilized Vasa Swaras, Vasa Swaras, vasicine (1) (chief marker compounds of A. vasica) and a marketed capsule formulation of A. vasica were compared. Vasicine (1) was found to be more orally bioavailable from lyophilized Vasa Swaras, with an overall minor conversion to vasicinone (2).Copyright © 2010 Elsevier B.V. All rights reserved.
