Antinociceptive Effects of Turkish Endemic Eryngium kotschyi Boiss. Roots by Bioactivity Guided Fractionation
Eryngium species (Apiaceae) are well known plants in ethnobotanical culture throughout world and also in Turkey. They are used as antitussive, diuretic as well as for analgesic and antiinflammatory purposes in traditional medicine. This study aimed to evaluate the antinociceptive activity of endemic Eryngium kotschyi Boiss. root extracts by bioguided fractionation. The antinociceptive activity of the extracts/fractions/compound was studied in mice using acetic acid induced writhing test and and hot plate test. The methanolic extract was sequentially partitioned with hexane, dichloromethane and water saturated n-butanol. Among the fractions, the n-BuOH fraction showed the most significant re…
