Identification and Characterization of the Phenolic Profile of A Hydroalcoholic Extract of Punica Granatum (Published)

More than half the world’s population use or used at some point a herbal because of its potential healing. The pomegranate, as well as another 70 medicinal plants are listed as species of interest to the public health system in order to generate new effective and safe medicines. The objective of this study was to evaluate a hydroalcoholic extract of Punica granatum about their biochemical and biophysical characteristics. The extract was serially diluted and exposed to different conditions. The values of wavelengths, absorbance, pH and conductivity were observed. The analysis values, it can be concluded that the extract in question has the characteristic of stability in the different conditions and that has possibly flavonoids, tannins and anthocyanins in its composition.

This research studied the effects of alkaloids and flavonoids extracts of Vitex doniana seeds on some pathogenic bacteria and fungi. The bacteria are: P. aeroginosa, B. subtilis, S. aureaus, E. coli and S. typhi. The fungi are C. albican and A. niger. It was found that the alkaloid and flavonoid extracts of the seed inhibited the above named five bacteria successfully. The alkaloid and flavonoids extracts of the seed cannot inhibit the above mentioned two test fungi. Alkaloid and flavonoids extracts of V. doniana seeds are antibiotic in action. This knowledge can help the new generation pharmacists in their formulation of new drugs to improve health care delivery.

Possible Anti-Hemolytic and Antioxidnt Role Of Ethanolic Extract Of Coriander On Irradiated Rats (Published)

Foods wealthy in antioxidants play an essential role in the prevention of diseases.Coriander (Coriandrum sativum L.), a conventional annual herb selected for assessing antihemolytic and antioxidant properties. To study the effectiveness of Coriandrum sativum as an antihemolytic and antioxidant agent, the oxidative stress was induced in rats by gamma radiation exposure with 4 Gy shot dose after 14 days oral administration of coriander extract (600 mg/kg b.wt). Exposing rats with 4 Gy gamma rays was significantly decreased RBCs, WBCs and Platelets counts. But the percentage of segmented cells as well as the activity of serum aspartate transaminase (AST) and endothline 1 (ET1) level was significantly increased after radiation exposure. Interestingly, among the tested parameter, the ethyl extract of coriander showed marked improvement in both haematological and biochemical changes. In conclusion, addition of coriander to food will increase the antioxidant content and may have potential as a natural antioxidant and thus inhibit unwanted oxidation processes.
