Total phenolic and phytosterol compounds and the radical scavenging activity of germinated Australian sweet lupin flour. The extracted total phenolic compounds increased obviously with increasing extraction temperature, especially when E. cottonii was fed as a starting material. Rumiyati(1), Jayasena V, James AP. TOTAL PHENOLIC CONTENT, FLAVONOID CONCENTRATION AND ANTIOXIDANT ACTIVITY OF Marrubium peregrinum L. EXTRACTS Milan S.

Total phenolic compounds and flavonoids were determined using Folin–Ciocalteu and HPLC, respectively.
Author information: (1)Faculty of Pharmacy, Universitas Gadjah Mada, Sekip Utara, Yogyakarta, Indonesia, 55281. The amount of total phenolic compounds increased with the increase in extraction temperature from 120°C to 160 and 200°C at the same reaction time. Phenolic compounds that contained in the plants have redox properties, and the properties allow them acting as antioxidants [6, 7].
The high contents of phenolic compounds indicated that these compounds contribute to the antioxidant activity. TPC activity is the process to figure out the amount of phenolic content in the samples.
In this month, values of phenolic compounds of Texas, Ferragnes and Nonpareil were 2.03 μg mg-1, 2.82 μg mg-1 …

3.1. Phenolic compounds in the leaves of Nonpareil, Texas and Ferragnes varieties were high in October (Figure 3) (p < 0.05). Results of the study revealed that all the plants tested exhibited excellent antioxidant activity with IC 50 in the range of 21.3 to 89.6 μg/mL. phenolic compounds in bulk lids in the regions of Tehran 9 and 22 with other areas (p<0.001), but there was no significant difference between the other regions. total phenolic compounds in the brands 5 (semi-fat) and 9 (full-fat) with other brands (p<0.001) but there was no significant difference between other brands.

Colorimetric spots were formed by reacting diazotized aminobenzenes namely sulfanilic acid, sulfanilamide, or aniline with TPCs in the extract to form an azo dye. Antioxidant Capacity and Determination of Total Phenolic Compounds in Daisy (Matricaria chamomilla, Fam. Fig 1.3: Total phenolic and total flavonoid content of the selected plants CONCLUSION The present study revealed the phenolic and flavonoid spectrum of medicinally important plants.
The present work describes a novel and rapid approach for evaluating total phenolic compounds (TPCs) in tea and fruits using colorimetric spots and the digital image-based (DIB) method. The amount of total phenolic compounds extracted at 200°C was almost twofolds than that obtained at 120°C.
