Abstract:

Five extracts (n-hexane, chloroform, ethyl acetate, n-butanol and water) of Scutellaria rivularis Benth. were evaluated for their anti-inflammatory activity against carrageenan-induced paw edema in rats and compared with indomethacin. The result indicated that chloroform extract proved to be the most effective in all of the extracts. Consequently, three major components (baicalin, baicalein and wogonin) of the chloroform extract were further tested for their anti-inflammatory activity using the same model. It was found that baicalin exhibits the greatest inhibition activity against carrageenan

Thus, de-colourization of sacha inchi shells before extraction using solvents could be a means to bring about the extract with a lighter colour, which could be applied in foods without constraints.
