Protocol
Structure Identification:
European Food Research and Technology. A, 2007, 224(4):483-488.
Phytochemical and biological investigationOf Stevia rebaudiana Bertoni; 1-labdane-type diterpene.[Reference: WebLink]

METHODS AND RESULTS:
Five labdane diterpenoids, austroinulin, iso-austroinulin, sterebin E, sterebin E acetate, and Sterebin A acetate, along with hydrocarbons, aliphatic alcohols, beta-amyrin, beta-sitosterol and stigmasterol were isolated from the chloroform soluble fraction of the methanol extract of Stevia rebaudiana leaves. Chlorogenic and caffeic acids were isolated from the EtOAc fraction.
CONCLUSIONS:
All the isolated compounds were identified using spectral tools. The chloroform and methanol extracts proved significant anti-inflammatory effect and caused marked inhibition of carrageenan-induced paw oedema in rats.
