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...

A crude acetone extract of the pit of date palm (Phoenix dactylifera L.) was prepared and its antiviral activity evaluated against lytic Pseudomonas phage ATCC 14209-B1, using Pseudomonas aeruginosa ATCC 25668 as the host cell. The antiviral activity of date pits was found to be mediated by binding to the phage, with minimum inhibitory concentration (MIC) of <10 μg ml(-1). The decimal reduction...

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...

in the present study, plumbago zeylanica linn. (plumbaginaceae) , one of the folk medicinal plants commonly used as antifertility agent was evaluated for its antifertility effect. five successive solvent extracts, petroleum ether, chloroform, acetone, ethanol and water extracts, of the stems of p. zeylanica were studied on estrous cycle at two dose levels, 200 and 400 mg/kg respectively.   of t...
