“…The total polyphenol content of the extracts was determined by ultra violet (UV) spectrophotometry (Perkin Elmer Lambda 25 UV-vis) at 760 nm using Folin-Ciocalteu reagent by the method of Othman et al [39] and Modnicki et al [40] (2009) [41,42] . The concentrations of the total polyphenols were determined in Gallic equivalents (GAE) per gram of the extract.…”

AIM:To investigate the presence and potency of natural enzyme inhibitors with hypoglycemic potentials amongst Eucalyptus Spp. by in vitro assays. METHODS:The leaf extracts of the three different Eucalyptus species [E. globulus (EG), E. citriodora (EC), E. camaldulensis (ECA)] were subjected to in vitro assay procedures to explore the prevalence of natural enzyme inhibitors (NEIs) after preliminary qualitative and quantitative phytochemical evaluations, to study their inhibitory actions against the enzymes like α-amylase, α-glucosidase, aldose reductase, angiotensin converting enzyme and dipeptidyl peptidase 4 playing pathogenic roles in type 2 diabetes. The antioxidant potential and total antioxidant capacity of the species were also evaluated. RESULTS:Major bioactive compounds like polyphenols (341.75 ± 3.63 to 496.85 ± 3.98) and flavonoids (4.89 ± 0.01 to 7.15 ± 0.02) were found in appreciable quantity in three species. Based on the IC50 values of the extracts under investigation, in all assays the effectivity was in the order of EG > ECA > EC. The results of the ferric reducing antioxidant power assay showed that the reducing ability of the species was also in the order of EG > ECA > EC. A strong correlation (R 2 = 0.81-0.99) was found between the phenolic contents and the inhibitory potentials of the extracts against the targeted enzymes. CONCLUSION:

The aim of this study was to determine the chemical composition, nutritional properties and antioxidant activity of Monkey apple methanol extract. Results expressed on dry matter basis revealed the seeds contained the following: 2.74% protein, 15.86% crude fat, 7.67% crude fiber, 468.74kcal, 82.01% moisture content, 5.72% ash, 88.98% carbohydrate. The seeds further contained considerable amounts of minerals and vitamins as follows: 14.14mg/100g for iron, 2.37mg/100g for potassium, 1434.38mg/100g for manganese, 82.71mg/100g for magnesium, 185.49mg/100g for calcium, 28.33mg/kg for ascorbic acid, 13.33mg/kg for thiamine and 55.83mg/kg for pyridoxine. Furthermore, it was found out that both the seeds and pulps were also rich in the following: 297.49-304.94mg QE/100g for total flavonoids, 2086.98-2304.72mgGAE/100g for total phenolics, 1.6-96400mg/kg for citric acid, 5880-9280mg/kg for malic acid, 960-1040mg/kg for tartaric acid, 30.8-38.8mg/kg for fumaric acids, 232-660mg/100g for oxalates, 1186.67-1320mg/100g for phytic acid and 130.23-515.23mg/100g for tannins. The seeds and pulp oils were also found to be rich in unsaturated fatty acids ranging from 46.27-50.21%. Our results therefore demonstrate that Monkey apple could serve as supplementary source of essential nutrient and antioxidant components with health benefits.
