“…Besides, the moisture, fibre, and ash content of vegetables and spices have also been regarded important for human health. Trace elements and heavy metals have certain risks [2], and thus it is important to determine the level of these compounds in widely consumed vegetables. In addition to vitamins, the presence of phytochemicals is also considered to be of crucial nutritional importance in the prevention of chronic diseases [3].…”

Objective: Capsicum annum L. is a well-known spice and has long been used in Chinese traditional medicine for the treatment of various ailments. So, the present study was aimed to analyse its nutritional profile and free radical scavenging activity. Methods:The green Capsicum annum L. cultivated in 24 Parganas [South], West Bengal, were studied for the quantitative analysis of proximate composition, mineral and vitamin content. Aqueous and hydroethanolic extracts were screened on a comparative basis for the presence of in vitro antioxidant potential including the total phenol and flavonoid content, along with ferric reducing power, and 2,2-diphenyl-1-picrylhydrazyl (DPPH), hydroxyl and superoxide radical scavenging activity. Results:The sample was found to contain 89.89% total carbohydrate, 13.48% soluble carbohydrate, 7.95% crude protein, 4.80% fat, 12.9% fibre, 95.42% moisture and 5.12% ash. Besides, the vegetable was also found to be abundant in vitamins and minerals like, sodium (24.4), iron (4.834), zinc (1.632), magnesium (92.612), manganese (0.88), calcium (19.562), copper (1.11), cobalt (0.02), chromium (0.016), boron (0.316), lycopene (2.4) and β-carotene (14.85) expressed in mg/100 g; and potassium (2.236), vitamin C (1.77), vitamin E (6.08), all expressed in g/100 g dry weight of the sample. The free radical scavenging activity, total phenol and flavonoid content of the aqueous extract were significantly higher than the hydroethanolic extract (p<0.05). Conclusion:It can thus be concluded that capsicum is a nutritionally rich spice and a potential source for antioxidant. The aqueous extract is more potent than the hydro-ethanolic extract in scavenging free radical.

This research was carried out to investigate key physicochemical parameters of milk samples collected from camel, cow and goat in Jigjiga district, Eastern Ethiopia. Sixty fresh milk samples were collected purposively from camels, cows and goats (twenty samples from each species) and analyzed. The results revealed that, cow milk had 6.30 ± 0.15 pH, 0.29 ± 0.04% titratable acidity, 14.6 ± 0.60% total solid, 0.75 ± 0.07% ash, 3.54 ± 0.12% protein, 5.54 ± 0.65% fat and 1.06 ± 0.03 specific gravity. Camel milk had 6.13 ± 0.11 pH, 0.36 ± 0.01% titratable acid, 13.65 ± 1.39% total solid, 0.73 ± 0.03% ash, 3.15 ± 0.15% protein, 3.93 ± 0.15% fat, and 1.03 ± 0.00 specific gravity. Results for goat milk was also recorded as 6.38 ± 0.08 pH, 0.33 ± 0.03% titratable acidity, 14.25 ± 1.16% total solid, 0.73 ± 0.07% ash, 4.62 ± 0.56% protein, 6.79 ± 0.38% fat and 1.04 ± 0.00 specific gravity. It can be concluded that goat milk had higher protein and fat content than cow and camel milk.

“…Some trace elements are essential and may have both curative and preventive roles in combating diseases, as they promote good human health. On the other hand, heavy metals such as lead and cadmium are nonessential and at elevated levels can be dangerous or toxic to the human system (11)(12). This study was designed to evaluate the heavy metals and mineral elements on the leaves of V. ambigua, V. oocephala and V. pupurea with a view to assess their therapeutic potentials or safety in relation to their uses.…”

Background: Vernonia species are widely consumed as vegetables or medicinal herbs for the treatment of various human diseases in Nigeria. Nevertheless, there exists a growing concern for consumption safety of those herbal plants, due to increasing environmental pollution. This is because plants can accumulate some heavy metals that constitute a potential risk to human health. Nonetheless, also essential elements may be accumulated in plants, which provide nutrients for combating diseases and maintaining human health. Objectives: The purpose of the study was to analyze some heavy metals and mineral elements on Vernonia ambigua, V. oocephala and V. pupurea commonly used in Northern Nigerian traditional medicine. Methods: Atomic absorption spectrometry (AAS) was used to determine the major elements (calcium and magnesium), trace elements (iron and manganese) and heavy metals (copper, cobalt, chromium, cadmium, lead and zinc). Results: We found a high Ca and Fe content in V. ambigua, Mg and Co in V. oocephala, and Cu and Cr in V. pupurea; in contrast, the last specie, showed low accumulation of Pb and Cd among all studied species. Conclusion: This study revealed that toxic elements concentrations are lower than the allowed dietary intake (ADI) in all the three Vernonia species. The quantitative estimation of these elements is important to understanding the pharmacological and/or toxicological actions of medicinal plants for safe use.
