Opis:
Oxidative stress occurs as a result of an imbalance between production of reactive oxygen species and the regulatory mechanism produced by human cells. The stress contributes to the pathogenesis of inflammatory diseases. Synthetic antioxidants like butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT) and ascorbic acid, are used in curtailing the menace of the stress. Their potential depends on the type of phytochemicals in the oil. It is on this basis this study aimed at isolating, characterizing and investigating antioxidant potential of rind essential oil of C. reticulata. To achieve this aim, 500g of fresh rinds of C. reticulata were pulverized and hydro-distilled for three hours. GC and GC-MS analysis of the oil revealed the abundance of hydrocarbon monoterpenoids (96%). The most abundant compounds in the oil were D-limonene (82.4%), γ-Terpinene (9.4%) and β-Myrcene (2.2%). The oil exhibited antioxidant activity, with IC50 value (10.73 μl/ml), which was lower to the activity of ascorbic acid (49.14 μl/ml). This shows that the oil is more active than ascorbic acid. Hence, the oil could be explored for the treatment of oxidative stress.

Opis:
The antimicrobial and antioxidant activities of extracted essential oils in some aromatic plants were determined. Phytochemical screening was conducted using standard qualitative techniques, while the essential oils was extracted from the Citrus limon linn leaf, Vitex trifolia seed and Cananga odorata by modified steam distillation apparatus. Furthermor, the plant materials were tested using Antioxidant activity and Antimicrobial activity test. Citrus limon linn produced large volume essential oil (1.4 ml), Vitex trifola (0.7 ml) and Cananga odorata (0.5 ml) after 3hours of steam distillation. Antioxidant activities test using DPPH method reveals that all the essential oil determined showed positive effect, but the oil extracted from Citrus limon linn leaf could be a better antioxidant than that of Vitex tifolia and Cananga odorat when compared to commercial Ascorbic acid. The antioxidant activities of the essential oils of different plants under investigation showed a variation which may be as a result of the difference in their chemical compositions. Antimicrobial activities showed that all the essential oils were inhibited on the entire five microorganisms being used. However, Citrus limonlinn showed highest inhibition on the organisms (E. coli, S. typhi C. Kleb, P. avengunosa and S. aureus) compared to Cananga odorata and Vitex trifolia.
