2-propanone

(prō`pənōn), CH3COCH3, colorless, flammable liquid. Acetone melts at −94.8°C; and boils at 56.2°C;. It is the simplest aliphatic ketoneketone
, any of a class of organic compounds that contain the carbonyl group, C=O, and in which the carbonyl group is bonded only to carbon atoms. The general formula for a ketone is RCOR′, where R and R′ are alkyl or aryl groups.

. Acetone is widely used in industry as a solvent for numerous organic substances and is a component of most paint and varnish removers. It is used in the manufacture of synthetic resins and fillers, smokeless powders (e.g., cordite), and numerous other organic compounds. Acetone is produced commercially chiefly by catalytic dehydrogenation of isopropanol.

Since hepatotoxic reactions were observed with traditional aqueous kava extracts as well as ethanolic and acetonic extracts, the used solvents appear to play no major role for the observed hepatotoxicity (Teschke et al.
Regarding ethanolic and acetonic kava extracts, the upper limit in Germany was 120mg kavalactones per day before the kava ban (Commission E 1990), determined by TLC and not by HPLC (Loew and Franz 2003).
However, the methanolic and acetonic extracts showed good, hot water extract showed moderate activities at the concentration tested.
At 8 mg/ml, the strongest reducing power was determined in acetonic extract with a value of 1.
A methanolic and an acetonic extract were obtained from the root, and a methanolic extract from the leaves of the same cultivar, consisting of 3 years old greenhouse kava plants.
No clear difference in the total amount of kavalactones was observed in the methanolic and the acetonic root extract, respectively.
The results showed a significant differences in mortality of insects to acetonic extract of O.
It was postulated that these traditional aqueous extracts contained a spectrum of other constituents compared to the industrial acetonic and ethanolic extracts which are commercialized in the western countries (Moller 2002).
The mutagenicity of the same acetonic extract was investigated by means of the Ames test using Salmonella typhimurium TA98, TA100, TA1535, TA 1537 and TA1538, with and without metabolic activation (rat liver S9 mix) at dosages of up to 2.
