Phytochemical Studies on Adhatoda Vasica Nees

A new triterpenoid, 3 alpha-hydroxy-D-friedoolean-5-ene (1), along with the known compounds, epitaraxerol (2) and peganidine (3), which have been isolated for the first time from the aerial parts of Adhatoda vasica Nees. The structures of these compounds were elucidated by spectral studies. X-Ray diffraction studies on a bronchodilating and hypotensive principle of A. vasica, vasicinone (4), were also carried out.
