Banana is a commercially important fruit, but its flavonoid composition and characteristics has not been well studied in detail. In the present study, the metabolism of flavonoids was investigated in banana pulp during the entire developmental period of fruit. 'Xiangfen 1,' a novel flavonoid-rich banana germplasm, was studied with 'Brazil' serving as a control. In both varieties, flavonoids wer...

The presence of phenolic, flavanoid and tannin compound content in the methanolic extract of Garcinia atroviridis were investigated in this study using UV-Vis Spectrometry and consequently find the relationship between the chemical contents with the antioxidant activity. Garcinia atroviridis has phenolic content the highest followed by flavonoid and tannin content. The antioxidant activities of...

In plants from temperate climates such as Arabidopsis thaliana low, non-freezing temperatures lead to increased freezing tolerance in a process termed cold acclimation. This process is accompanied by massive changes in gene expression and in the content of primary metabolites and lipids. In addition, most flavonols and anthocyanins accumulate upon cold exposure, along with most transcripts enco...

The work studied the effect of germination on proximate, phenol and flavonoid content and antioxidant activities (AOA) of African Yam been (AYB). Germination was done in controlled dark chamber (100% RH, 28C). The proximate, phenol and flavonoid content and antioxidant activities before and after germination were investigated. The crude protein, moisture, and crude fiber content of germinated A...

Total flavonoid and phenolic content, antiradical properties and external flavonoid profiles on extracts of six samples of flower heads of cultivated Arnica montana was assessed. The studied samples were compared in relation to location of cultivation, origin of the seeds, time of harvesting, method of propagation: in vitro and in vivo. Four flavonoid aglycones were detected of examined exudate...

This study compared the total flavonoid content of Glycyrrhiza glabra L. leaf and root extracts. Results suggested that the total flavonoid content in the leaf extract was obviously higher than that in the root extract. Pinocembrin, the main compound in the leaf extract after purification by column chromatography, showed good antioxidant activity and nitrite scavenging capacity, but moderate in...

 Background: The use of natural products as anticancer and antioxidant agents has a long history. Several drugs currently used in chemotherapy were isolated from plant species. Objective: The aim of this study was to evaluate cytotoxicity and antioxidant activity as well as phenol and flavonoid contents of five plant species of Solanaceae family. Methods: Five plant species of Solanace...

Plants are almost reach sources of phenolic compounds such as flavonoids which are the most importantnatural antioxidants. Antioxidant compounds are essential for protecting human body against oxidativestress. However use elicitors could increase the antioxidant activity of plant. The purpose of this studywas to evaluate the effects of Chitosan on the content of phenolic and flavonoid compounds...

Kaempferol-3-O-gentiobioside, the major flavonoid glycoside in Indonesian Cassia alata was quantified in various parts of the plant. The mature leaf was found to contain the highest content of this metabolite. A decrease of the flavonoid content in the juvenile leaf during the period of October through December was also observed. The contents ranged from 2.0 to 5.0% and 1.0 to 4.0% in mature an...

BACKGROUND Sorghum possesses phenolic compounds that are health-promoting constituents of the grain. There are approximately 40 000 sorghum accessions, many of which have not been evaluated for the grain's health-promoting potential. Conventional methods for measuring total phenolic content, flavonoid content and 2,2-diphenyl-1-picrylhydrazyl (DPPH)-scavenging capacity are time-consuming and la...
