“…In North America, of the 17 species of Vernonia all have the same effective properties as a blood purifier, uterus toner and helps also in the prevention of atherosclerosis [22,41]. Many herbalists and naturopathic doctors recommend aqueous extracts for their patients as treatment for anemia, nausea, diabetes, loss of appetite, dysentery and other gastro intestinal track problems.…”

Abstract:The proximate analysis and the phytochemical constituents were investigated in Magnifera, Morinda lucida, Parquetina nigrescens, Oscmium gratissimum, Chenopodium ambrosioides and Veronia amygaldalina using standard reference methods. The proximate analysis in % showed that Chenopodium ambrosioides had the highest amount of ash content of 17.30 and moisture content of 89.40 while Magnifera indica had the lowest amount of ash content 12.04 and moisture content 68.40. Veronia amygaldalina had the highest amount of protein 30.02 and carbohydrate 54.00 while Parquetina nigrescens had the least amount of protein 25.06 and carbohydrate 40.23. Parquetina nigrescens had the highest amount of crude fibre of 25.05 while Chenopodium ambrosioides had the highest amount of crude fat 18.22. The moisture content was found to be 89.40%, ash content 17.30, fat 18.22%, protein 30.02%, crude fibre 25.05% and carbohydrate 54.00%. The phytochemical constituents indicated flavonoid 28.58% alkaloid 25.84% and tannin 2.94% in Magnifera indica, Veronia amygaldalina and Morinda lucida respectively. The presence of high secondary metabolites in the leaves are good indication that if the plant is subjected to further research such as identification and characterization of plant, bioactive compounds with strong biological activities may be isolated and novel compounds may also be identified.

“…This study showed that the antioxidant activity of the ethanolic extracts was higher than that of the aqueous extracts, and compared favourably with synthetic antioxidant BHT and BHA [29]. However another study reported that methanol extract displayed highest antioxidant activity followed by acetone and water extract [30].…”

Vernonia Amygdalina (VA) is a tropical African plant of the Asteraceae family and is occasionally cultivated for its medicinal uses, which include as a treatment for diarrhea, skin wounds, fever mastitis and worms infection. The aim of this study is to isolate and elucidate the structure of some of the chemical constituents from the leaf of Vernonia Amygdalina and its bioactivities. The methanol extract of Vernonia Amygdalina, after repeated chromatography led to the isolation of a different compound, one of this compound (MM-4) is partially characterized based on the spectral data (IR, 1 H NMR, 13 C NMR, and DEPT) and extracts from Vernonia Amygdalina has been shown to have antimicrobial activity.
