the antibacterial and antioxidant activities of methanol and acetone extracts of three marine algae, including hypnea hamulosa, gracilaria corticata and enteromorpha intestinalis wereinvestigated.antioxidant activities were determined by means of total antioxidant capacity, total phenolic compounds, dpph radical scavenging activity and ferric reducing antioxidant power. antibacterial activity w...

the phenolic compounds of pomegranate (punica granatum l.) peel extracted by two methods (solvent and ultrasound-assisted) with five solvents (acetone, methanol, ethanol, water and ethyl acetate) were compared with supercritical fluid extraction (sfe). the total phenolic compounds were determined according to the folin-ciocalteu reagent using tannic acid as standard. the overall results showed ...

Antibacterial activity of two cyanobacterial strains i.e. Nostoc polludosum and Cylindrospermum licheniforme was studied. Both cyanobacterial strains were isolated from agricultural fields of Varanasi, India. Crude extracts of both strains in five solvents i.e. Ethanol, Petroleum ether, Acetone, Methanol, and Chloroform were screened against two human pathogenic bacteria i.e. S. aureus and E. c...

Many investigators of tyrosine oxidation have used systems in vitro such as slices, minces, and, more recently, homogenates of liver. During our search for a suitable preparation other than liver slices for studying the conversion of phenylalanine to tyrosine, an extract of rat liver acetone powder was tested. Although the phenylalanine to tyrosine conversion was not demonstrated, it was found ...

That the adrenal gland plays a specific r81e in fat metabolism has been suggested for many years (1). More recently this hypothesis received further support when Long and Lukens (2) reported that adrenalectomy produces a marked reduction in the acetone body excretion of the depancreatised cat. This observation soon received ample confirmation by other investigators who found that adrenalectomy ...

new approaches for treatment of infectious diseases in aquatic animals have important roles in aquaculture technology progress. in the present study, in vitro effects of different extracts of propolis, royal jelly and pollen obtained from beehives have been investigated on aquatic pathogenic bacterial isolates. the isolated bacteria identified on the basis of their biochemical properties and se...

The potential antioxidant and antiproliferative activities of acetone and methanolic extracts of green micro algae, Desmococcus olivaceous and Chlorococcum humicola, were evaluated in vitro. Total phenolic and flavonoid content were determined in both the extracts. Free radical (DPPH) scavenging potential was higher in Desmococcus olivaceous than cholorococcum humicola. Reducing power ( H2O2 ) ...

A total of 115 different plant extracts from our collection, representing 96 plant species, have been evaluated for in vitro antileishmanial activity against L. amazonensis promastigotes. In addition, the extracts were screened for cytotoxic activity against BALB/c mouse macrophages in order to assess a selectivity index. Crude extracts that showed a selectivity index (CC50 for macrophage / IC5...

In the present investigation, effects of Ramalina capitata acetone extract on micronucleus distribution on human lymphocytes, on cholinesterase activity and antioxidant activity (by the CUPRAC method) were examined, for the first time as well as its HPLC profile. Additionally, total phenolic compounds (TPC), antioxidant properties (estimated via DPPH, ABTS and TRP assays) and antibacterial acti...

The potency of Solenostemma argel (asclepiadaceae) as anti-inflammatory and antioxidant effects was investigated. Three solvent extract were used for extracting (polyphenolic, flavonoids and tannins) from the leaves of Solenostemma argel (S. argel). Three complementary antioxidant systems: (DPPH∙ free radical scavenging, Fe2+-chelating and iron reducing power) as well as the total phenolic, tot...
