Abstract Plant identification is an overwhelming task due to different biological attributes and great diversity in plant species. In the absence of physical markers, molecular techniques have become useful for the identification of species of origin of medicinal plant seeds, pastes, and formulations of suspected plants. The ITS region of nuclear rRNA was amplified from thirteen different toxic plant species by using universal primer ITS 1 & 4. Nucleotide sequences of all selected plants were submitted in NCBI and accession numbers were acquired. The results of this study give accurate identification of thirteen plant species and proved the ITS region of 18s-26s nuclear ribosome to be an important tool for phylogenetic analysis and species identification of plants. The sequence was aligned with top matched reference sequence and presented in Clustal Omega software for making a phylogenetic neighbour tree. The significance of these findings is paramount in forensic toxicology scenarios especially when fragmentary plant material is found in the stomach/intestine and its morphological identification becomes impossible. In these circumstances, the PCR based molecular technique surely plays a significant role in solving complicated forensic cases. صلختسلما ةيجولويبلا تامشلا ببشب ةقاش ةمهم تاتابنلا ديدتح نوكي ام ابًلاغ ةيئايزيفلا تاملاعلا بايغ لظ فيو .ةيتابنلا عاونألال يربكلا عونتلاو ةفلتخلما أاشنم عاونأا ىلع فرعتلل مادختشلا في ةديفم ةيئيزلجا تاينقتلا حبشت هذه فيو .اهب هبتشلما ةيتابنلا تارشحتشلماو ينجاعلماو ةيبطلا روذبلا افًلتمخ اعًون رشع ةثلاثل rRNA نم ITS ةقطنم ميخشت تم ةشاردلا يمدقت تمو .ITS 1 & 4 لماشلا ئدابلا مادختشاب ةماشلا تاتابنلا نم لوشلحا تمو NCBI في ةراتخلما تاتابنلا عيملج تاديتويلكوينلا لشلشت .ديقلا ماقرأا ىلع ايًتابن اعًون رشع ةثلاثل اقًيقد ادًيدتح ةشاردلا هذه جئاتن يطعتو ةمهم ةادأا نوكتل 18s-26s يوونلا موشوبيرلا نم ITS ةقطنم نأا تتبثأاو عاونألا ديدتحو ينيلجا عونتلا نم ققحتلاو ،تاتابنلل يثارولا ليلحتلل تمو قباطتم يعجرم لشلشت ىلعأا عم لشلشتلا ةمءاوم تتمو .ةيتابنلا روطتلاو ءوشنلا ةرجش ءاشنإل Clustal Omega جمانرب في هيمدقت .يرواجتلا مومشلا ملع تاهويرانيش في ىوشق ةيمهأا تاذ جئاتنلا هذه برتعتو /ةدعلما في ةأازمج ةيتابن ةدام ىلع روثعلا متي امدنع ةشاخ يئانلجا نم فورظلا هذه في .لًايحتشم يجولوفرولما اهديدتح حبشيو ،ءاعمألا يدؤوت لشلشتلما زايرميلوبلا لعافت ىلع ةمئاقلا ةيئيزلجا ةينقتلا نأا دكؤولما .ةدقعلما ةيئانلجا اياشق لح في امًهم ارًود Arab Journal of Forensic Sciences & Forensic Medicine 2020; Volume 2 Issue (2), 171-181 Techical Note
