Effects of ethoxyquin on the color stability of oleoresin paprika extracts and amount of residual ethoxyquin, a color stabilizer, in commercial extracts were determined. The oleoresin paprika extracts dissolved in ethanol gave the highest maximum photo-absorbency at 444-458 nm, with the color index of United States product 2-6 times higher than that produced in India. The residual solvents in oleoresin paprika extracts were mainly acetone and methanol, although some other extracts also contained small amounts of hexane. HPLC analysis was determined as a proper analytical method for residual ethoxyquin assay in the oleoresin paprika extracts, particularly when hexane was used as a solvent. The residual ethoxyquins were detected in the extracts produced in US and Spain which had relatively high color indices.

This study has attempted to examine the effect of Artemisia princeps and A. argyi on liver function-related enzymes in rats with $CCl_4$ adminisration. The activities of serum aspartate aminotransferase(AST), alanine aminotransferase(ALT) and alkaline phosphatase(ALP) from A. princeps were decreased by 33, 23 and $19\%$, respectively, compared to control. The activities of AST, ALT and ALP from A. argyi were decreased by 37, 33 and $26\%$, respectively. Total phenol contents were 10.2 mg/mL and 4.7 mg/mL in A. princeps, and A. argyi, respectively. Also, flavonoid contents were $6.1\;mg\%\;and\;3.6\;mg\%$ in A. princeps, and A. ar효i, respectively. Ethanol extract from A. argyi showed higher electron donating ability toward DPPH than A. princeps. A total of 31 volatile components(3 hydrocarbons, 10 terpenes, 5 carbonyls, 8 alcohols and 5 esters) were indentified in A. princeps, and A. argyi. The major volatile components of A. princeps were $\delta$-3-carene($2.2\%$) in terpenes and nerolidol($0.9\%$) in alcohols. The major volatile components of A. argyi were eugenol($1.4\%$) in alcohols and thyl pentadecanoate($1.1\%$) in esters.
