NovelbCarboline Alkaloidfrom Peganum Harmala AsAntibacterial Agant

A novel﷿bcarboline alkaloid isolated from the aerial parts of Peganum harmala L. (Gen: Phyeophylaceae) have been characterized as l-thioformyl-8- �≤ -D-glucopyranoside-bis-2,3-dihydro-isopyridinopyrrol.It is one of﷿bcarboline alkaloids derivatives. The chemical structure was elucidated on the basis of elementary analysis and spectroscopic studies (UV, IR, 1 H-NMR & MS). The isolated coshowed significant antibacterial activity against Streptococcus pyogenus.
