This paper is the first phytochemical and ABTS cation radical decolorisation activity, cupric reducing antioxidant capacity, anticholinesterase and DNA damage protection effect of endemic Verbascum pinetorum (Boiss.) O. Kuntze. Phenolic profile of V. pinetorum were qualified and quantified by UHPLC-ESI-MS/MS analysis. Malic acid (47250.61±2504.28 µg/g) and luteolin (7651.96±527.98 µg/g) were fo...

The aim of this study was to investigate the antioxidant activity of orange (Citrus auranthium) flesh (OF) and peel (OP) extracted with acetone, ethanol, and methanol. Antioxidant potential was examined by measuring total phenolic content (TPC), 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity (RSA), total radical-trapping anti-oxidant potential (TRAP), oxygen radical absorbance...

Acetone is a ubiquitous compound due to its source strength of about 95 Tg/yr and poor reactivity in the gas phase [1]. The latter allows acetone to reach the upper troposphere where it is mainly removed by photolysis reactions. Acetone degradation has an impact on the oxidizing capacity of the (upper) troposphere producing HOx and ozone. Another potential sink for acetone in the tropospheric m...

Breath analysis has been considered a suitable tool to evaluate diseases of the respiratory system and those that involve metabolic changes, such as diabetes. Breath acetone has long been known as a biomarker for diabetes. However, the results from published data by far have been inconclusive regarding whether breath acetone is a reliable index of diabetic screening. Large variations exist amon...

Early evidence for the metabolic activity of acetone was derived from studies showing a partial disappearance of administered doses of the compound (1, 2). It is clear from these investigations, and from subsequent work (3,4), that most of the acetone excreted as volatile iodoform-forming substance appears in the exhaled air; a smaller fraction is excreted in the urine. Schwarz (1) demonstrated...

[1] Acetone is one of the most abundant carbonyl compounds in the atmosphere and it plays an important role in atmospheric chemistry. The role of the ocean in the global atmospheric acetone budget is highly uncertain, with past studies reaching opposite conclusions as to whether the ocean is a source or sink. Here we use a global 3-D chemical transport model (GEOS-Chem) simulation of atmospheri...

in iranian traditional medicine, there are some report regarding the anticonvulsant effect of ferula gummosa boiss. in this study, anticonvulsant activity, neurological deficits and lethality of the root acetone extract of this plant were evaluated in mice. the extract exhibited dose-dependent prevention of tonic seizures induced by pentylenetetrazole (ed50 = 154.4 mg/kg). however, the extract ...

Comparatively few methods are available for the determination of the acetone bodies in blood. Marriott (1913-14, b) has described a method by which the nephelometric technique described by him (1913-14, a) could be applied to the determination of these substances in blood. Scott-Wilson’s reagent was used in this determination (Scott-Wilson, 1911). Marriott used this method in studying the relat...

Due to the need for new fumigants to control insects that attack food commodities, the toxicity of acetone was determined on some species of stored pest insects in Urmia University in the year 2000. In empty space tests, the LC50 values of acetone for Oryzaephilus surinamensis (L.), Callosobruchus maculatus (F.), Tribolium confusum (Duv.) and Sitophilus granarius (L.) were 15.40, 15.51, 17.55 a...
