“…Changes in amylase activity have also been reported during ripening of mango fruits (Mangifera indica). The climacteric rise in mango fruit was reported to be marked by an appreciable increase in the activity of amylase (Lima et al, 2001). In Cucumis melo which is commonly called muskmelon or cantaloupe, a progressive increase in the amylase activity has been observed with the degradation of starch throughout the period of ripening in the fruit.…”

Solanum species (eggplants) are edible, highly valued constituents of the Nigerian food and indigenous medicines. In this study, the activities of enzymes involved in carbohydrate degradation such as amylase and invertase were evaluated in two Solanum species viz Solanum melongena (round and oval varieties) and Solanum aethiopicum during different ripening stages. The activity of amylase was found to reduce significantly in both varieties of Solanum melongena (p < 0.01) while there was a non -significant reduction in amylase activity of Solanum aethiopicum (p > 0.01) from the unripe to the overripe stage. Also, invertase activity in both varieties of Solanum melongena was observed in this study to be significantly reduced (p<0.01) from the unripe to the overripe stage, with a nonsignificant reduction in invertase activity occurring in Solanium aethiopicum (p > 0.01). The variations observed in the activities of these carbohydrate degrading enzymes correlate with the decrease in glucose level that has been reported during ripening in Solanum species; thereby confirming the ripe and overripe eggplants as nutritionally good diet for diabetic patients and individuals, who are watching their weight.© JASEM http://dx.doi.org/10.4314/jasem.v18 i2.20Introduction: Solanum species, which are also known

“…Fuchs et al (1980) observed that in developing phase of mango fruits parts increased amylase activity corresponding to the increase in fruit part weight which suggested that changes taking place during ripening and development time as well as in the nature of the amylolytic enzyme activity during these development phases. Moreover, Lima et al (2001) also found increased activity of α -amylase in mango fruits (Mangifera indica L.) and decreased starch content which was an important role of carbohydrate metabolism during ripening of mango.…”

The aim of this study was to determine the effects of maize (Zea mays L.) in diabetic patients in vitro. Three varieties (Golden, Sultan and Agatti: 85) were used to study the level of antioxidants and bio-molecules. Results showed that maize ears parts of all three varieties were more effective inhibitor in the oxidation process. Variety Golden silks was found to contain abundant activity of protease (22488 units/g f.wt.), α-amylase (390 units /g f.wt.), total sugar contents (307 mg/g f.wt.), and nonreducing sugar (288 mg/g f.wt.), and husks were rich in reducing sugar contents (16.9 mg/g f.wt.), and grains (kernels) in (15 mg/g f.wt.) protein content. Variety Sultan silks contained total phenolic content (38100 µM/g f.wt.), husk contained peroxidase activity (88655 U/g f.wt.), and grains manifested catalase (555 U/g f.wt.) activity. In varietyAgatti85 a highest activity of superoxide dismutase (292 U/g f.wt.) and malondialdehyde content (35 µM/g f.wt.) was recorded in silks. The findings of this research showed that maize probably inhibits the reaction of oxidation and decreases the complications occurring in diabetes mellitus. It was concluded that performed active parameters (total phenolics, SOD, peroxidase, catalase) may be responsible for higher antioxidant activity, which can be successfully used to reduce the extent of diabetes in the patients.

“…10000 ppm crude ethanolic extract is more effective in lowering blood glucose level when compared to 5000ppm of the same extract which suggests that at higher concentration of the hexane extract, hypoglycemic activity is observable. In general, according to Lima et al (2001) in "Changes in Amylase Activity Starch and Sugar Contents in Mango Fruits Pulp", the contents of reducing sugar may be attributed to lower activities of amylase. The presence of reducing sugar in the extracts (10000ppm of hexane, aqueous and crude ethanolic) according to the phytochemical screening test of Billacura and Laciapag (2017) make them susceptible to inhibit the activity of alpha-amylase the greatest.…”

“…The presence of reducing sugar in the extracts (10000ppm of hexane, aqueous and crude ethanolic) according to the phytochemical screening test of Billacura and Laciapag (2017) make them susceptible to inhibit the activity of alpha-amylase the greatest. Some possible reasons by which these plant extracts exert this kind of effect may be due to their action on carbohydrate-binding region of alpha-amylase enzymes that catalyze the hydrolysis of the internal alpha-1,4-glucosidic linkages in starch and other related polysaccharides have also been targeted for the suppression of postprandial hyperglycemia (Lima et al, 2001).…”

In this study, Crescentia cujete Linn. fruit was extracted using 95% ethanol and was concentrated in vacuo. The crude ethanolic extract (CEE) was then subjected to solvent partitioning using hexane and water. Fresh (FE) and decocted (DE) extracts were also prepared by m/v ratio of sample:water. Among the plants samples in vitro hypoglycemic assay, 10000ppm hexane extract possessed the highest ability to inhibit (55.21%) the activity of alphaamylase. Also, 10000ppm AE and CEE exhibited 32.87% and 32.64% inhibition, respectively. FE, DE, HE, AE and CEE were administered to the 24-hour starved Mus musculus via oral gavage for eight consecutive days. The initial blood glucose level (BGL) of the test organisms was recorder and determined using one-touch glucometer. Twenty four hours after the eightday treatment, the blood glucose level was determined. In vivo hypoglycemic assay revealed positive BGL lowering in the FE, 10000ppm of HE, AE and CEE upon comparison to the inducer, Alloxan. Protective potential assay also revealed significant lowering of BGL in the previously mentioned extracts with the addition of 1:1 m/v decocted and 5000ppm CEE. Moreover, Alloxan group was monitored for five days after its administration on the third day thus proving Alloxan's degradation. Colorimetric determination of glucose concentration in the plant sample was performed and it shows the increase in sample extract concentration is proportional to the amount of glucose in it. The pure decoction 4:0 m/v ratio revealed the highest glucose concentration (453.30ppm), while the 100ppm of CEE has the lowest glucose content (55.66ppm). The extracts of Crescentia cujete Linn. reveals hypoglycemic potential and its utilization before the occurrence of the metabolic disorder diabetes mellitus can help in regulating BGL in the blood.
