Opis:
In this work, we prepared cobalt oxide nanoparticles using Celery stalks and green tea leaves extract. The synthesized cobalt-oxide NPs were characterized using X-Ray diffraction. This showed the highest peak and top control (222) at (38.18 degree) with regard to Camellia sinensis extract and (220) at (30.14 degree) for Apium graveolens extract, Field Emission scanning electron microscopy (EF_SEM) at the range of 21-72 nm, revealed the highly uniform shape of particles, while UV-Visible spectroscopy techniques recorded the highest value of the absorptive at 230 nm and the energy band gap to be 3.55 eV for Camellia sinensis and 225 nm and energy band gap 3.85 eV at Apium graveolens, respectively. Our results indicate that the best achievable result in inhibiting bacteria such as Staphylococcus aureus and Pseudomonas aeruginosa comes by way of using Camellia sinensis extract (27-29 mm).

Opis:
In this study, the proximate, mineral, anti-nutrient content and sensory evaluation of the tea brands sold in Nigeria were evaluated. Fours brands including Lipton tea (LPT), Anti Malaria Tea (AMT), Green Tea (GRT) and Eternal slimming tea (SLM) and lemon grass tea (LEM) as control were studied. The official methods of Analysis of Association of Analytical Chemists were adopted for the analysis. Results for proximate showed that GRT showed significant difference (P>0.05) Moisture content (5.99 %) while SLM had significant low value p≤0.05 (4.85 %) compared to LEM (control) (5.12). The Protein content of the tea samples was discovered in traces having SLM as the highest (0.46 %). The crude fat as ether extract of the samples ranged between LPT (3.18) as the highest (3.18 %). SLM appeared to have high (6.08) value in Ash and GRT lowest value. LEM (control) had a high (88.58 %) value in Carbohydrate compared to the other tea brands with LPT as the lowest (86.03 %) value. The results of the mineral analysis showed that LEM has the highest (28.31 mg/kg, 85.96 mg/kg and 18.31 mg/kg) for calcium and potassium content respectively SLM had the highest (7.35 mg/kg) value for Magnesium. Antinutrient results showed that all teas brands had traces of alkaloid at various values ranging from GRT (0.15 mg/kg) to SLM (0.01 mg/kg). Phytate and oxalate was not detected at all in GRT and was discovered in traces the other tea brands. The average taste scores of tea samples ranged from 6.60-5.30 with highest (6.75) taste scores assigned to sample LPT while lowest (4.95) taste scores were observed in sample AMT. The four tea brands evaluated in this study are nutritionally valuable, including the natural extract of lemon grass which contains zinc, which helps boost the immune system and acts as an antioxidant that protects the body. The content of this tea brands and lemon grass are also safe.
