“…Flavonoids on the other hand prevent oxidative stress and have strong anticancer activity. They also protect against allergies, tumors and ulcers [15]. Plant phenolics are believed to play a key part as defense compounds when environmental stresses, such as high light, low temperatures and pathogenic infection lead to an increased production of free radicals and other oxidative species in plants [16].…”

The present study investigated the phytochemistry and antioxidant activity of Pterocarpus angolensis (Mubvamaropa) from Mupandawana. Pt. angolensis has numerous medicinal uses. The bark, sap, leaves and roots are all used to treat different ailments. The sap is used to stop nose bleeds, treatment of ulcers and kill ringworms. Several studies have supported the use of the tree’s sap to treat cataracts, malaria as well as skin inflammations. Pterocarpus angolensis bark was collected from Gutu, Masvingo province and authenticated by a plant taxonomist at the Zimbabwe National herbarium (Mr Chapano). The bark was cleaned using distilled water and oven dried at 40°C for 4 hours to constant weight. Size reduction was achieved using a Thomas-Wiley laboratory mill model with a 2 mm sieve mesh. The phytochemical analysis revealed that the ethanolic extract had more phyto-constituents than the water extract which only four phyto-constituents present all of which were weakly positive. DPPH scavenging activity was 95.11% at a concentration of 500 μg/mL bark extract, while that of the control, ascorbic acid, was 97.60%. Ascorbic acid had an IC50 value of 4.35 µg/mL while the bark extract had a value of 150.64 µg/mL.

“…Pterocarpus erinaceus foliage is known to provide excellent fodder for livestock. In many Sub-Saharan African countries, the foliage and immature pods of the plant are harvested for feeding livestock, especially during the dry season when livestock feed becomes increasingly scarce [1] [5]. In Sub-Saharan Africa, Pterocarpus erinaceus is known to be one of the most exploited plant species for traditional medicinal purposes.…”

“…Leaves of P. erinaceus are used for the treatment of severe fever, the bark for the treatment of toothache and mouth-related diseases, and the exudates or resins are used for the treatment of stomach ulcers, diarrhea, dysentery, and intestinal worm infections. In North America and Europe, P. erinaceus was widely used for the treatment of chronic diarrhea until the middle of the 20 th Century [1] [10] [11]. Figure 1 below depicts the image of P. erinaceus.…”

Plants have always been exploited worldwide for food, medicines, shelter, and other purposes because they are readily available, affordable and acceptable to a large populace of the world. The study was conducted to gather information on the proximate composition of fresh and dry leaves of Pterocarpus erinaceus. The proximate composition of the leaf samples was determined using the standard methods of analysis of the Association of Official Analytical Chemists (AOAC). Proximate analysis of the fresh leaf samples of the plant shows a higher moisture content compared to the dry leaf samples. The total fat and total ash contents of the fresh leaf samples were however lower compared to values recorded for the dry leaf samples. The dry matter content of fresh leaf samples was also lower compared to that of the dry leaf samples. Fresh leaf samples again recorded the least crude protein content compared to dry leaf samples. Carbohydrates content in fresh leaf samples was higher compared to dry leaf samples. Generally, higher proximate values were recorded for dry leaf samples than for fresh leaves. Dry matter and moisture contents were detected in high quantities in both fresh and dry leaf samples of P. erinaceus. These results could be a justification for the multiple uses of the plant leaves across Sub-Saharan Africa. Further research should be carried out on the mineral, phytochemical and vitamin composition between the fresh and dry leaves of the plant.

This study described the chemical composition, antioxidant and antibacterial activities of the ethanol and aqueous extracts of fresh and dried leaves of Phyllantus amarus (PA) (Stone breaker), Cymbopogon citratus (CC) (Lemon grass) and combination of stone breaker and lemon grass (PA/CC and DL/DP) using standard methods. The proximate and mineral results showed that both fresh and dried samples of Phyllantus amarus and Cymbopogon citratus were rich in crude fibre (18.53%, 14.65%), ash (16.27%, 2.29%), potassium (95.56 mg/100g, 54.04 mg/100g), calcium (58.57 mg/100g, 7.05 mg/100g), and sodium (15.23 mg/100g, 9.84 mg/100g) respectively. The ability of the extracts to scavenge 2, 2 diphenyl -2- picryl-hydrazyl (DPPH) radical showed that the fresh PA had the highest scavenging activity of 91.12 mg/g, followed (PA/CC) 90.93 mg/g and dried PA (85.61mg/g). The phytochemical composition of the extracts also revealed that they contain high content of cardiac glycoside (11.62 mg/g - 64.81 mg/g), terpenoid (14.56 mg/g - 69.66 mg/g), phenol (14.73 mg/g - 53.93 mg/g), saponin (22.61 mg/g - 30.47mg/g). Dried lemon and dried Phyllantus amarus (DL/DP) was found to be rich in Vitamin A (22.22 mg/g), while the lowest value of Vitamin E (0.36 mg/g) was obtained from fresh lemon grass (0.36mg/g). Antibacterial assay carried out on the two leaves extracts showed that they produced mild antibacterial activity against some foodborne pathogen (Bacillus cereus, Shigella dysenteriae, Escherichia coli, Salmonella spp, Staphylococcus aureus, Pseudomonas spp). with zones of inhibition of 4.3 mm -9.1mm. Further studies should be carried out to investigate the employment of the leaves in production of functional food
