General description

Petroleum ether is a low boiling point fraction having boiling point in the range of 40-60°C. Extracts of leaves of Litchi chinensis Gaertn. (Sapindaceae) have been prepared in petroleum ether and were evaluated for antiinflammatory, analgesic and antipyretic activities.

Application

Petroleum ether may be used in absorption chromatographic purification of organic compounds.

Pharmacological studies were conducted with the petroleum ether extract of leaves of the plant Litchi chinensis Gaertn. (Sapindaceae) on experimental animals. The extract was found to possess antiinflammatory, analgesic and antipyretic activity. Acute toxicity studies revealed that the extract, up
