The study on antioxidant activity of ulvan-calcium derivative

Ulvan is a water-soluble polysaccharide that is extracted from the algae Ulva pertusa (Chlorophyta). In this study, ulvan-calcium derivative (U-calcium) was prepared and calcium content was 5.2%. Ulvan-calcium could effectively scavenge on 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2’-azino-bis (3-ethyl-benzothiazolie-6-sulfonic acid) (ABTS), hydroxyl, and superoxide radicals. The inhibition rate on superoxide...

Development and validation of a new method to quantify vitexin-2''-O-rhamnoside on Passiflora L. extracts

The genus Passiflora L. is the most representative of the Passifloraceae family and includes about 500 species. The aim of this work was to analyze three different passion fruit species in relation to vitexin-2´´-O-rhamnoside content by high-performance liquid chromatography coupled to a diode-array ultaviolet detector. Samples were prepared by water infusion (10% w/v), dried by lyophilization, and stored in...

Chemical composition and antibacterial activity against Escherichia coli of extracts of a common household plant

Plants have long been a source for a wide variety of compounds with medicinal properties; of significant interest are plant antimicrobial compounds. Given the continual increase in bacterial resistance, it is imperative that new antimicrobial compounds need to be discovered. The purpose of this study was to screen some common household plants for antibacterial activity, specifically against Escherichia coli. Leaves of...
