The structures of the isolated compounds were assigned on the basis of ID and 2D NMR spectral analysis and by comparison with the reported data. publisher: Chemical Publishing Co. date: 2014 type: Article type: PeerReviewed identifier: Khan, I.U. and Khan, F.U. and Hussain, J. and Badshah, S. and Muhammad, N. and Khan, R.A. and Kait, C.F. and Ali, M.A. and Khan, H. and Aslam, M.W. and Hussain, I.
