Acanthophora spicifera, red algae are known to possess antioxidant activities. The objective of this study is to evaluate the ameliorative effect of the ethyl acetate extract of A. spicifera against the puffer fish Arothron hispidus induced biochemical alterations and oxidative stress. 24 Mice were divided into four groups were used in this study. Group 1 received normal saline as control, Grou...

The antioxidant activities of the petroleum ether, ethyl acetate, n-BuOH and water extract fractions from Dracaena cambodiana Pierre ex Gagnep were evaluated in this study. The ethyl acetate fraction contained the highest amount of total phenolics and total flavonoids, and showed the greatest DPPH˙, ABTS+ and Superoxide anion radical-scavenging capacities. The DPPH˙, ABTS+ and Superoxide anion ...

The antioxidant activities of the ethanol, petroleum ether, ethyl acetate, n-butanol and water extract fractions from the seeds of papaya were evaluated in this study. The ethyl acetate fraction showed the strongest DPPH and hydroxyl free radical-scavenging activities, and its activities were stronger than those of ascorbic acid and sodium benzoate, respectively. The n-butanol fraction demonstr...

BACKGROUND The Cheilanthes albomarginata Clarke (CA), a fern belonging to Pteridaceae family, is found mainly in India, Nepal, Pakistan and Bhutan at an altitude of 1300-2700 m. It grows mostly in the rock crevices on slopes. Juice from the rhizome of CA has been used to treat peptic ulcer. In this study, the biological activities (antioxidant, anti-inflammatory, anti-adipogenic and anti-obesit...

objectives this study was designed to determine the chemical composition, in vitro antioxidant activity, and total phenol content of various extracts of s. chloroleuca. materials and methods dried aerial parts of the plant were crushed, then sequentially extracted with n-hexane, ethyl acetate, and methanol. the fractions of s. chloroleuca were subjected to silica gel column chromatography and s...

salvia genus is one of the largest genera of the lamiaceae family. its species have been used for a wide variety of disorders in the local traditional medicine systems. therefore, the genus has been the subject of several phytochemical and biological studies. the aim of the study was to identify the major antioxidant compound(s) from the methanol extract of salvia verticillata using activity-gu...

ducrosia anethifolia (dc.) boiss. is belongs to the apiaceae family. it is one of the three species of iranian ducrosia boiss. species growing wild in several areas of the country. in this research, we extracted the essential oil and it analyzed by gc/ms. the analysis of essential oil from leaves of d. anethifolia about 19 constituents was identifed and percentage composition was determined (94...

Amoora cucullata (Meliaceae), a mangrove plant, has folkloric reputation as a medicinal agent in Bangladesh. In this study, the n-hexane, ethyl acetate and methanolic extracts of the stem bark of this plant were subjected to microbiological investigation and brine shrimp lethality bioassay. In case of antimicrobial screening, the ethyl acetate and methanolic extracts appeared to be potent in te...
