ABSTRACT
Background: Medicinal plants of Genus Ferula are prennial herbs of Apiaceae family which are widely distributed all around the word. Many of Feula species are exclusive and endemic to Iran which has widespread uses in traditional medicine as food additive, as well as a carminative, antispasmodic and expectorants. Coumarins, flavonoids and sulfur-containing compounds with different biological effects have been reported from the plant
Objective: The phytochemical investigation on total extract of the aerial parts of Ferula persica Willd var. Latisecta collected from the Central Alborz Protected Area was subjected with the aim of purification and determination of main metabolite constituents of the plant extract
Methods: Dried and powdered plant material was extracted by maceration method. Then the extract was concentrated under reduced pressure to leave a residue which was defatted and chromatographed on a silica gel column by increasing slightly the polarity with solvent. After the serial fractionation the fractions were compared by TLC, and those giving similar coumarin spots were combined and further purified on PLC to give a pure natural compound
Results: After the purification step the remarkable constituents were obtained. Elucidation of results by spectral methods [IR, 1H-NMR, 13C-NMR and DEPT] demonstrate that a coumarin namely: Auraptene [7-genaryloxycoumarin] was isolated from the aerial parts of F. persica. var. latisecta
Conclusion: F. persica is an endemic and endangered species of medicinal plants of Iran which contains different natural compounds such as coumarins. So the Protection of the plant for its economic and scientific uses is so important
ABSTRACT
Echinococcosis or hydatidosis is a chronic, zoonotic worldwide infection that occurs by the larval stages of taeniid cestodes of the genus Echinococcus. Iran is known as endemic region for this infection in the world. Vaccination has been considered as a good prevention method for this disease. Recombinant vaccines containing EG95 protein, against E. granulosus, has shown a high degree of protection against E. granulosus infection. In this study EG95 gene was extracted from Iranian isolates of E. granulosus and then cloned and expressed in expression vector. Protoscoleces were collected from sheep hydatid cysts. Then DNA and RNA were extracted from protoscoleces, and amplified by PCR and RT-PCR with specific primer. Afterward the purified RT-PCR products were successfully ligated into pTZ57R/T plasmid vector. The pcDNA3 plasmid was used as expression vector and Eg95 fragment sub cloned into this plasmid. The pcEG95 plasmid was digested by restriction enzymes to confirm cloning of this gene in pcDNA3 plasmid. In last step, the subcloned gene was expressed in CHO as eukaryotic cell. EG95 fragment successfully was subcloned in pcDNA3 and EG95 protein was expressed by eukaryotic cell. The recombinant EG95 protein was confirmed by SDS-PAGE and Western blot. Recombinant plasmid of pcEG95 was constructed successfully and express of recombinant EG95 protein was confirmed
