Interest in edible beans as nutraceuticals is increasing. In the present study, the individual phenolic acids, the total phenolic content (TPC), the total flavonoid content (TFC), and the antioxidant and antidiabetic potential of 13 varieties of rice beans from China were investigated. Eight phenolic compounds (catechin, epicatechin, p-coumaric acid, ferulic acid, vitexin, isovitexin, sinapic a...

The effect of variation of harvest season and cultivar on the total phenolic content (TPC), total flavonoid content (TFC), HPLC-UV/DAD profile and antioxidant properties in Vaccinium ashei (Rabbiteye blueberry) leaves grown in Brazil was evaluated. The cultivars collected in December and March were Aliceblue, Powderblue, Climax, Bluegem and FloridaM. It was observed that leaves from March had t...

In the past two decades public interest in herbal products has increased significantly in Europe, especially in the plant-based products from non-European traditions. Eleutherococcus senticosus has been used for the treatment of inflammatory diseases, anemia, and rheumatoid arthritis. The Eleutherococcus senticosus fruits intractum was examined for the content of phenolic acids (LC-ESI-MS/MS), ...

Ultrasonic-assisted extraction (UAE) was developed to extract phenolic and flavonoid antioxidants from Clerodendrum cyrtophyllum Turcz leaves. The optimal experimental parameters for antioxidant extraction from C. cyrtophyllum leaves were measured using single-factor experimentation combined with response surface methodology (RSM). Total phenolic content (TPC) and total flavonoid content (TFC) ...

Preservative fruits have gained popularity in recent years as part of food consumption, but their benefits towards human health are not known. This study compared total phenolic (TPC), total flavonoid (TFC), β-carotene, lycopene, ascorbic acid (AA) contents and antioxidant properties between fresh and pickled papaya. The results indicated that mean TPC (mg gallic acid equivalent/100 g dry sampl...

Abstract. Nurlela, Nurfalah R, Ananda F, Ridwan T, Ilmiawati A, Nurcholis W, Takemori H, Batubara I. 2022. Variation of morphological characteristics, total phenolic, and flavonoid in Adenostemma lavenia, A. madurense, platyphyllum. Biodiversitas 23: 3999-4005. has long been used as a herbal medication. Despite some studies regarding the morphology potency carried out, variation traits, phenoli...

Antioxidants have been widely used in the food industry to enhance product quality by preventing oxidation of susceptible substances. This work was carried out to maximise the recovery of total phenolic content (TPC), total flavonoid content (TFC), 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) radical-scavenging capacity and 2,2'-diphenyl-1-picrylhydrazyl (DPPH) radical-scaveng...

Introduction. Globally, the consumption and production of tea are on rise because its beneficial constituents. Scarce literature exists effects extraction periods contents biologically important protective phytochemicals such as phenolics, flavonoids, antioxidants in locally produced teas Uganda. Aim. This study determined aqueous total phenolic content (TPC) local Camella sinensis, black prima...

In this study, antioxidative activities of aqueous extract of Biarum bovei (BBE) in stabilizing of canola oil during storage at 20°C was evaluated. For this purpose, the total phenolic (TP), flavonoids (TFC), and tocopherol content (TTC) of the extract were determined and β-carotene bleaching system was used to assess the antioxidant efficacy of BBE. The amount of TP, TFC, and TTC in BBE indica...
