“…The results of this study demonstrated that the biological effects including α-glucosidase inhibitory and antioxidant activities from the fruits of E. multiflora significantly depended on the flavan-3-ol contents. Our work was similar to those of the previous studies (30,33). The most predominant flavan-3-ol was epicatechin gallate and its content showed 1.000 (25% ethanol extract, 44%), 2.008 (50% ethanol extract, 64%), 2.038 (75% ethanol extract, 71%), and 1.574 mg/g (100 % ethanol extract, 78%), respectively.…”

The purpose of this study was to investigate the phytochemical contents and biological activities, including α-glucosidase inhibitory activity and antioxidant activity, from the fruits of Elaeagnus multiflora using different solvent systems. The 50% ethanol extract of this species showed the most potent α-glucosidase inibitory activity (88.5%) at a concentration of 1 mg/mL. Moreover, this extract also displayed the strongest antioxidant activity in each assay, showing 96.3% in DPPH scavenging activity, 98.2% in ABTS scavenging activity, and 2.5% in reducing power. The highest total phytochemical contents, including flavan-3-ols, phenolic acids, and flavonoids, were observed in the 50% ethanol extract. Interestingly, flavan-3-ols (3.150 mg/g) were detected at a significantly higher total content than those of phenolic acids (0.380 mg/g) and flavonoids (not detected). Additionally, the contents of individual phytochemicals showed remarkable differences, especially the epicatechin gallate (2.008 mg/g) and gallic acid (0.099 mg/g), which were the predominant constituents of each phytochemical type. Therefore, our results suggest that the 50% ethanol extract of E. multiflora fruits has strong biological activities, which are correlated with high phytochemical contents.

“…For methanolic and acetone extracts differences between shorter and longer extraction were rather smaller and not important. There was no correlation between polyphenols or catechins content and activity The activity of methanolic and aqueous extracts from parsley leaves against DPPH • was investigated by Wong and Kitts [2006]. They achieved lower results, i.e.…”

“…It is consistent with results obtained in the reported experiment. In turn, Wong and Kitts [2006] reported on 54% chelating capability in methanolic extracts and 47% chelating capability in aqueous extracts. The lower results may be due to a different chemical composition of the experimental material as well as to losses of antioxidants at the stage of samples preparation or extraction.…”

a b s t r a c tWithania somnifera Dunal, commonly known as ashwagandha, has been used for centuries in ayurvedic medicine to increase longevity and vitality. Various groups of researchers support its polypharmaceutical uses by confirming anti-inflammatory, immuno-modulatory and antistress properties in the whole plant extract. The present investigation adds up the antioxidant assay profiling in this list. The Ashwagandha root extracts were prepared in different solvents of varied polarity in a sequential fashion. The maximum yield (5.8%) and total polyphenolic compounds (TPC, 88.58 µg GAE/mg extract) were recorded in methanolic fraction. All the extracts were screened for their potential antioxidant activities using tests such as free radical scavenging activity, metal chelation activity, hydroxyl radical scavenging activity, superoxide radical scavenging activity and hydrogen peroxide scavenging activity. Results of study showed methanolic extract as the most potent fraction and a strong correlation could be established with its TPC. Overall, the study suggests that Ashwagandha root extract could be of great use for the preparation of antioxidant rich nutraceuticles to treat various human diseases and its complications. It is quite likely that the antioxidant capacity of plant/root is one of the reasons for its established anti-stress, anti-inflammatory and immunomodulatory properties.
