Universitas Negeri Surabaya. When I am calculating the amount of the respective contents from the standard curve in the equation Cc1XVN cTotal content of the phenol in mgg. Best regards 0 votes 0 thanks.

C z mg GAEml vol. Results were expressed percentage ww and calculated using following formula Total phenolic content ww GAEVD10 6 100W GAE - Gallic acid equivalent μgml V - Total volume of sample ml D - Dilution factor W - Sample weight g. Using the equation below you can calculate total phenolic content of that sample in mg GAEg.

The correlation of total phenolic and flavonoid content with antioxidant capacity is shown in Figure 5 ab. 300µL of crude extract mixed with 600µL ofFC reagent10 and 24 mL of sodium bicarbonate700mM. Of chemical used in assay ml.

Y00005x 0039 x y-003900005 y0602 x1126 ugml - this is the concentration in extract. Firstly from the measured absorbance and calibration curve you should calculate the concentration in ugml. Vulgaris root were evaluated for the amount of total phenolic content and total protein content by using Folin-Ciocalteus method and Lowerys method respectively.

Where C total phenolic content mg GAEg dry extract c concentration. C c vm Where C is the total content of phenolic compounds mgg c is the concentration of gallic acid determined from the standard curve mgmL v is the volume of the extract mL m is the weight of pure tissue g. The total phenolic content can be calculated as natural compound gallic acid equivalent GAE by the following equation.

T is the total phenolic content in mgg1 of the extracts as GAE C is the concentration of gallic acid established from the calibration curve in mgml1 V is the volume of the extract solution in ml and. The total phenolic contents in all samples was calculated the using the formula. The total phenolic contents TPC can be calculated by the Folin-Ciocalteu colorimetric method based on the oxidation-reduction reaction by using gallic acid as standard since it.

Then the total amount of TPC in 100 ml is 1126 ug and that is the amount in 1 g of extract. Total volum was 33 mLy 00398x - 00006 R² 09971GAE equivalent value. The total phenolic content could be determined using UV spectrophotometer The oxidizing reagent was FolinCiocalteu reagent.

Total Phenolic and Flavonoid content of Hot Water Extracts of Herbs and Spices. The total volume of extract is 10ml 1ml of extract 05ml Folin ciocalter reagent 5ml distilled water 15ml sodium carbonate and this was made up to 10ml. The total phenol is determined by the FolinCiocalteu method the reaction mixture contained 200 μL of diluted extracts 800 μL of freshly prepared diluted Folin Ciocalteu reagent and.

The method is composed of a water extraction of dried extracts with sonication followed by reaction with the Folin-C reagent. The extract weigh in this case is. Estimation and comparison of total phenolic and total protein content in Phyllanthus emblica amla fruit and Beta vulgaris beet root root.

The total phenolic content of the methanolic root extract calculated from the calibration curve R2 0998 was 4517 170 gallic acid equivalentsg and the total flavonoid content R2 0999 was 35 220 rutin equivalentsg Table 1. Of mixed herbs F1 showing the flavonoid content of 040 01 mgg. 783 gThe crude extracted 783 g were dissolved in 40 ml methanolAmount used in FC assay.

Emblica fruits and B. After 1 h the absorbance was measured to determine the total phenolic contents in both extracts separately using the formula c c1 vm where c total phenolic content in mgg in gae gallic acid equivalent c 1 concentration of gallic acid established from the calibration curve in mgml v volume of extract in ml and m the weight. Then y is the average absorbance of your sample and calculate for x which is the phenolic content of your sample expressed as grams per Gallic acid equivalent or grams per tannic acid equivalent depending on the one you used for the calibration curve.

Apologise for in the clip my wrong word usage of absorption at the place of absorbanceThe total phenolic content of different compounds in the plant was. H 2 O 2 R 2 066 were observed at a 95 confidence level. H 2 O 2 R 2 071 and total flavonoids DPPH R 2 084.

Phenolic compounds have redox properties which allow them to act as antioxidants 20. High correlations between antioxidant capacity and total phenols DPPH R 2 075. C c Vm.

Add to 05 ml of. 3 describes the TPC and TFC of all the three formulations of herbs and spices while figure4 shows their graphical presentation. From your straight line equation make x the subject formula Ie x y-0041100131.

T C XVM. A single-laboratory validation of a method using Folin Ciocalteus phenol reagent Folin-C reagent for determination of total phenolic content of selected dietary supplement extracts was performed. Content of phenolic compounds in the extracts were calculated by the following formula.

First you need to use equation y 11924x - 00307 to calculate the value of x Where y Absorbance x concentration from the calibration curve This implies that x y 0030711924 x.
