AbstractThe commercially processedThe phytochemical analysis showed that the extract contained flavonoids, terpenoids, glycosides, tannins and saponins. In the acetic acid-induced writhing test, the extract significantly reduced the number of writhes at 100 and 200 mg/kg but not so much at 50 mg/kg. In the formalin-induced paw lick test, the effect was similar to that of the acetic writhing test. The analgesic effects were comparable to that of indomethacin used at 10 mg/kg. In the anti-inflammatory test, the extract reduced the formation of oedema especially at a dose of 200 mg/kg. In the anti-oxidant test, the extract was found to possess a free radical-scavenging property and is concentration related.The use of this extract for medicinal and nutritional purposes may have thus been justified; however, caution must be exercised in its use to prevent the toxic effect.

Introduction: Free radicals have singlet electron in their outer layer rendering them high reactivity against biomolecules (i.e., DNA, carbohydrates, proteins, and lipids). Oxidative stress is created when the production of free radicals exceeds their removal by antioxidant systems and is involved in the pathogenesis of several diseases such as diabetes, arthritis, inflammatory conditions, and various cancers. Regarding the therapeutic potential of nanoparticles (NPs) in human diseases, the purpose of this study was to synthesize cerium oxide NPs using Origanum majorana leaf extract. Methods: Cerium oxide nanoparticles (CeO2 -NPs) were synthesized using aqueous leaf extract of O. majorana. The sizes of NPs were characterized by a particle size analyzer. The antioxidant properties of the CeO2 -NPs were determined by Ferric-reducing antioxidant power (FRAP) assay. The anti-inflammatory effects of the NPs were also determined by measuring gene expressions of IL-1β and IL-10 using real-time polymerase chain reaction (PCR). Results: The CeO2 -NPs were successfully synthesized using O. majorana leaf extract. The results of FRAP assay showed that the anti-oxidant activities of CeO2 -NPs at concentrations of 50, 100, and 400 μg/mL were 75%, 77.1%, and 94.5%, respectively. Moreover, interleukin 10 (IL-10) gene expressions increased by 4.6 folds while the expression of IL-1β gene decreased by 0.75-fold in HUVECs. Conclusion: The CeO2 -NPs synthesized using the aqueous extract of O. majorana demonstrated antioxidant and anti-inflammatory properties. Therefore, these NPs can be used as potential therapeutic agents in medicine.

Coumarin Compounds

Coumarin and its derivatives are widely spread in nature. Coumarin goes to agroup as benzopyrones, which consists of a benzene ring connected to a pyronemoiety. Coumarins displayed a broad range of pharmacologically useful profile.Coumarins are considered as a promising group of bioactive compounds thatexhibited a wide range of biological activities like anti-microbial, anti-viral,antiparasitic, anti-helmintic, analgesic, anti-inflammatory, anti-diabetic, anticancer,anti-oxidant, anti-proliferative, anti-convulsant, and antihypertensiveactivities etc. The coumarin compounds have immense interest due to theirdiverse pharmacological properties. In particular, these biological activities makecoumarin compounds more attractive and testing as novel therapeuticcompounds.
