Sorghum biscuits were enriched with mushroom powders (Lentinula edodes, Auricularia auricula and Tremella fuciformis) at 5%, 10% and 15% substitution levels. An in vitro gastrointestinal digestion was used to evaluate the effect of this enrichment on the phenolic content and soluble peptide content as well as antioxidant activities of the gastric or intestinal supernatants (bio-accessible fractions), and the remaining portions of phenolic compounds, antioxidants and β-glucan in the undigested residue (non-digestible fraction). The phenolic content of the gastric and intestinal supernatants obtained from digested mushroom-enriched biscuits was found to be higher than that of control biscuit, and the phenolic content was positively correlated to the antioxidant activities in each fraction (p < 0.001). L. edodes and T. fuciformis enrichment increased the soluble protein content (small peptide) of sorghum biscuits after in vitro digestion. All mushroom enrichment increased the total phenolic content and β-glucan content of the undigested residue and they were positively correlated (p < 0.001). The insoluble dietary fibre of biscuits was positively correlated with β-glucan content (p < 0.001) of undigested residue. These findings suggested that enriching food with mushroom derived dietary fibre increases the bioavailability of the non-digestible β-glucan and phenolic compounds.

Green leafy vegetables are the most underexploited class of vegetables despite high nutritional value. The current study has been focused on the evaluation of anti-oxidant status of fresh and dehydrated under- utilized green leafy vegetable namely Mukia maderaspatana (L.) (Family: Cucurbitaceae), an indigenous plant; traditionally it is used as an ingredient of various cocktail preparations for the management of severe inflammatory disorders in Indian system of medicine. The total phenolic content (TPC), total flavonoid content (TFC) and total antioxidant activities were evaluated for the ethanolic extract of leaves to assess the in vitro antioxidant activities. The results showed that there exist a linear correlation between polyphenol content and antioxidant property. The ethanolic extract of dehydrated Mukia leaves showed the highest phenolic content (269.34 ± 0.78mg GAE/g), and total antioxidant activity (543±46 µmol Trolox/100 g). HPTLC analysis has revealed the presence of significant quantity of Quercitin (26.52%), an important flavonoid of tremendous antioxidant, anticancer and ant inflammatory properties in both the fresh and dehydrated leaves which might be the chief bioactive principle in Mukia.

Abstract:Herbal infusions are among the most widely consumed beverages throughout the world. Their popularity arises due to not only their pleasant aroma and taste, but also their high phenolic content and antioxidant activity. A vast number of in vitro studies revealed their high phenolic content, together with strong antioxidant activity. However, the majority of them seem to ignore some important physiological parameters, such as bioavailability or bioaccessibility. The present study was planned to evaluate the stability of phenolic content and antioxidant activities of seven most widely preferred herbal infusions. A stimulated version of gastrointestinal infusion was added to the study for comparative purposes. The results indicated the loss of both phenolic content and antioxidant activity of herbal infusions after being submitted to digestion.

Abstract Polyphenolic compounds reportedly produce physiological effects that are beneficial to health. Bee products are particularly rich in polyphenolic compounds. We determined the antioxidant capacity and the phenolic and flavonoid compounds content of 81 samples of honey. We used the Folin-Ciocalteu reagent method to evaluate the total phenolic content. The antioxidant activities were evaluated using in vitro scavenging assays of 2,2-diphenyl-1-picrylhydrazyl (DPPH ) and hydroxyl radicals (OH ), Trolox equivalent antioxidant capacity (TEAC ), and ferric-reducing antioxidant capacity (FRAC ). Total phenolic content ranged from 40.3 to 193.0 mg gallic acid equivalents (GAE )/100 g; the flavonoid content varied from 1.4 to 7.5 mg quercetin equivalents (QE)/100 g. Eucalyptus honeys exhibited significantly higher phenolic content and free radical-scavenging activity than clover honey samples (p<0.05 for all). Principal component analysis explained 73% of the differences observed in antiradical activity with respect to floral origin. Total phenolic content may be more useful than the radical-scavenging assay for detecting antioxidant capacity in honey; it also represents the variable that most appropriately discriminated among these honeys.

Abstract This research aimed to determine the yield, total phenolic content (TPC), in vitro sunscreen (SPF), and antioxidant activities (AA) of Damonorops draco resin (DDR). The DDR was macerated with ethanol at various concentration (EC) namely 100% (E100), 90% (E90), 80% (E80), and 70% (E70) and the DDR:solvent ratio (D:S) were 1:5, 1:10, and 1:15. This research showed that the interaction between the EC and D:S affected AA, SPF, and TPC of DDR extract (DDRE), but it didn’t affect the DDRE yield. The DDR extraction with E70, E100, and D:S of 1:15 produced the highest DDRE yield. The extraction with E70 and three different D:S produced DDRE with the highest TPC. The highest AA of DDRE was obtained from extraction with E80 and D:S 1:10 (E80-10), E70-15, and E90-5 respectively. The highest SPF of DDRE was obtained from the extraction with E90-15, E70-15, E90-5, and E70-10, respectively. The extraction with E70 and D:S of 1:15 is the best extraction condition because it produces DDRE with a yield of 17.4±3.9%-20.71±1.6%; TPC of 263.93±5.25 mg GAE/g DDRS; AA with an IC value of 78.3±0.3 ppm, and sunscreen with an SPF value of 33.1±0.0.

Phenolic content and antioxidant activity of two common fruits of Bangladesh, namely Phyllunthus emblica and Elaeocarpus floribundus, were measured in water, methanol, ethanol, acetone and hexane extracts. Several in vitro models including phosphomolybdenum assay, DPPH free radical scavenging assay, FRAP assay and reducing power assay were used to assess the antioxidant activity of these extracts in comparison with reference antioxidants. Between the two fruits, P. emblica showed higher phenolic content and antioxidant activity in all the solvents used. In the DPPH scavenging assay, the activity of P. emblica extracts was close to reference antioxidants, ascorbic acid and BHT. Besides, considering the solvents used, extracts of both fruits had the highest phenolic and antioxidant activity in polar solvents. The correlation coefficient between total phenolics and antioxidant activities was found statistically significant. These findings suggest that P. emblica could be an excellent antioxidant resource for industries like food, pharmaceutical, and cosmetics.
