in the present study, we have reported the total phenolic content, total flavonoid content, antioxidant and antimicrobial activity of aerial parts of salvia leriifolia extracts and fractions. methanolic, n-hexane, chloroform, and ethyl acetate extracts were screened to analysis their antioxidant activities by four complementary test systems, namely dpph free radical scavenging activity (rsa), t...
Herb Kalanchoe pinnata is grown as weeds in the tropical countries like India. It has a wide range of active constituents which has potent medicinal properties. The main objective was to overview the total antioxidant capacity of the herb Kalanchoe pinnata. Antioxidant activities were evaluated in terms of total phenolics content, total antioxidant activity, and reducing power. Different studie...
UNLABELLED It is possible that brucellosis may be related to increase free radical production and antioxidant depletion. Thus, in the present study we aimed to evaluate the oxidative status in patient with brucellosis and healthy controls. METHODS This study includes the patients with brucellosis diagnosed by clinical findings and positive agglutination titer. The paraoxonase, ceruloplasmin, ...
Leafs have contain wide antioxidant range which may provide prevention against radical oxygen species. The aim of this work was to measure the antioxidant capacity of 15 commercially available leaf extracts (ethanol, methanol, water) using ferric reducing antioxidant power (FRAP) assay and trolox equivalent antioxidant capacity (TEAC) assay. Also we evaluated total phenolic and monomeric anthoc...
In order to screen the Catalpa plant with high antioxidant activity and confirm the corresponding active fractions from Catalpa ovata G. Don, C. fargesii Bur., and C. bungei C. A. Mey., total flavonoid contents and antioxidant activities of the extracts/fractions of Catalpa plant leaves were determined. The determined total flavonoid content and antioxidant activity were used as assessment crit...
Black liquor alkaline lignin and magnesium lignosulfonate were liquefied at 320 C. The antioxidant abilities of the liquefaction products were compared with the raw materials. Results showed that the total phenol content and unit antioxidant power of both alkaline lignin liquefaction products (ALLP) and magnesium lignosulfonate liquefaction products (MLLP) were improved, and ALLP had a larger i...
