TLM was also subjected to preliminary phytochemical screening test for various constituents.

. The maximum amount of TPC was recorded with the methanol extract of B. The total flavonoid content TFC was determined according to Dewanto Wu Adom and Liu 2002 with a modification. The total yield total phenolic TPC and total flavonoid contents TFC of all the fractions were also determined.

In conclusion the propolis extracts showed stronger antioxidant potential with higher TPC and TFC values. Acta Agraria Debreceniensis 2020. However the cooking time considered 5 min was too short to significantly affect the TPC and antioxidant activity.

Similar trends were observed in various antioxidant assays and microwave processing exhibited highest antioxidant potency composite index 8652. The TPC and TFC were evaluated using FolinCiocalteu reagent and aluminum chloride colorimetric method respectively. TPC Total Phenolic content TFC Total flavonoids Content Crepidium acuminatum antioxidant antioxidant activity ROS.

Quercetin was used as standard and the absorbance was measured at 510 nm. Determination of total phenolics TPC flavonoids TFC and antioxidant activity by DPPH ABTS and reducing power assays. The TPC and TFC in bee bread bee pollen beeswax and honey are presented in Figure 1.

This study also noted the presence of bioactive compounds from local stingless bee propolis that could potentially be utilised for their medicinal and health benefits. The presence of phytochemicals and then analyzed for TPC and TFC using gallic acid and rutin as reference standard. Mutabile rind followed by 80 ethanol extract.

The total phenol content TPC of all 12 plant extracts under study was found in ranging from 444 to 18191 μg of GAEmg as Gallic Acid equivalents. This result is concordant with the observation of who reported that cooking time did not significantly affect the TPC and antioxidant activity of edible mushrooms. TPC of the samples varied from 03 02 to 285 03 mg TAEg FW whereas TFC of the samples ranged between 01 01 and 153 03 mg REg FW.

Almost four times lower TPC value was determined in the bee bread 823 024 mg GAEg. Boiling reduced TPC by 1074 whereas other processes enhanced TPC and TFC by 29681054 and 5122645 respectively. The highest TFC was reported in ethyl acetate peel extracts of both yellow and green lemon peels.

All the processes reduced the levels of phytates. TFC significantly correlated to TPC r 057 as well as to chicoric acid r 073. After 5 min 0375 mL of 03 M AlCl 3 6 H 2 O solution was added and the mixture was allowed to stand for 5 min.

Study on Total Phenolic Content TPC Total Flavonoid Content TFC and Antioxidant Activities of Urtica dioica. This study aimed to examine total phenolic contents TPC total flavonoid contents TFC proximate mineral contents and the in vitro antioxidant potentials of the spina-christi Ethiopian. 17372075 Development of the antioxidant indexes FRAP TFC TPC of scabbing resistant apple varieties in storage.

TFC was calculated by aluminum chloride colorimetric assay. Alata 533 01 mg GAEg dry weight and 28 00 mg QEg dry weight respec- tively. TPC was determined by Folin-Ciocalteu colorimetric method using gallic acid as standard and various concentrations of the extract solutions were measured at 760 nm.

The total phenolic contents TPC 121931 mg GAEg extract of TLM while total flavonoid contents TFC of TLE 609 22 mg RTEg extract were. View in full-text. The TPC had a superior linear correlation r20817 with 22-azinobis 3-ethylbenzothiazoline-6-sulfonic acid values.

The antioxidant capacities of the extracts were evaluated by DPPH ABTS and FRAP method respectively. The oxygen radical absorbance capacity ORAC of extracts ranged from 1144 to 4288 mg Trolox equivalent TEg DW extract whereas ORAC for TPC and TFC was 474024019 mg TEg and 0721122 g TEg respectively. TPC and TFC measured in undigested extracts were generally significantly p 005 lower than the corresponding gastric digests of all the investigated co-products with the exception of water and 100 ethanol extracts of marc and the increments followed similar trends as observed for undigested samples in terms of solvent extracts and co-products with.

Among the investigated Ephedra species the highest TPC and TFC were found in E. Briefly 85 mL of 20 ethanol was mixed with 085 mL of the extract and 0375 mL of 05 M NaNO 2. نتایج جستجو برای TPC and TFC.

Figure 1showed also that TPC FC 2363 0014 g GAE100 g and TFC SP 1265 0023 g rutin100 g provided by the MAE method were higher than those obtained by UAE followed by CSE and SC-CO 2. MihályOrosz-Tóth SándornéKincses متن کامل. The major phenolic compounds identified were gallic acid vanillin cathechol and ferulic acid.

The antioxidant potential of the different extracts was. While antioxidant activities were determined by DPPH radical scavenging and FRAP assays. TFC reported in ethyl acetate peel extracts of yellow and green lemon are 25925 095 mg REg extract and.

Antioxidant as compared to hydroalcolic and alcoholic extracts. Total phenolic contents TPC were 772 1125 1249 and 2624 mg GAE100 g for HAD ID USV and FD respectively. There was a significant and positive correlation between rosmarinic acid and antioxidant activity r 046.

The TPC was within the range from 047 004 to 3252 219 mg GAEg and its highest value was determined in the bee pollen 3252 219 mg GAEg. The highest TPC was determined in the water extract of N. Data represents the mean of three replicates and each letter a-c indicates significance at P 005 from publication.

Overall time did not have a significant effect on the TPC and TFC of the garlic extracts. Total phenolic content TPC and total flavonoid content TFC were measured using a Folin-Ciocalteau reagent and AlNO3-NaNO2complexometry respectively. The TPC and TFC values of commercial tomato pastes were 20962 1702 mg gallic acid equivalent GAE and 4252 485 mg catechin equivalent CE respectively and they were significantly higher p 005 than those of homemade counterparts which had the TPC and TFC values of 11225 5301 mg GAE and 3424 860 mg CE100 g respectively.
