Total Phenolic Content, Total Flavonoid Content and Radical Scavenging Activity from Zingiber zerumbet Rhizome using Subcritical Water Extraction
Subcritical water extraction (SWE) is an alternative technique that implement water as a solvent. The objective of this work was to compare the efficiency of SWE in temperature range from 100ºC to 180ºC at extraction times ranging from 5 to 25 minutes with an ethanolic soxhlet extraction in terms of total phenolic content (TPC), total flavonoid content (TFC) and radical scavenging activity (RSA...
متن کاملAntioxidative Ability of Defatted Rice Bran Extract Obtained by Subcritical Water Extraction in Bulk Oil and Aqueous Dispersion Systems
Defatted rice bran was treated with subcritical water between 120 and 240°C. The extraction temperature af fected the total carbohydrate and protein contents of the extracts. In the tested temperature range, the total carbohydrate and protein contents were the highest at 180°C and 210°C. The DPPH radical scavenging activity of the extracts increased with increasing extraction temperature up to ...
متن کاملFree Radical Scavenging Activity and Total Phenolic Content of Methanolic Extracts from Male Inflorescence of Salix aegyptiaca Grown in Iran
This study was designed to examine the in vitro antioxidant activities and total phenolic contents of the methanolic extracts from male inflorescence of Salix aegyptiaca L. grown in Iran. The methanolic extract (ME) and its three fractions including water (WF), butanol (BF) and chloroform (CF) were prepared and then their antioxidant activities, as well as total phenolic contents, were evaluate...

متن کاملEnhancement of Phenolic Production and Antioxidant Activity from Buckwheat Leaves by Subcritical Water Extraction
To enhance the production of phenolic compounds with high antioxidant activity and reduce the level of phototoxic fagopyrin, buckwheat leaves were extracted with subcritical water (SW) at 100~220°C for 10~50 min. The major phenolic compounds were quercetin, gallic acid, and protocatechuic acid. The cumulative amount of individual phenolic compounds increased with increasing extraction temperatu...
