Aerial parts of Compositae plants were harvested from pastures and crop fields of Sunchon area at vegetative stage to determine their antioxidant activity. Among 13 species, three species Taraxacum officinate, Breea segeta, and Artemisia princeps were selected as potent plant materials. Through measurement by Rancimat and TBARS method, antioxidative effect was the greatest in Taraxacum officinate among plant species. Antioxidative index (AI) investigated by Rancimat showed Siegesbeckia glabrescensi was 1.51 while commonly-used antioxidants, BHT and ascorbic acid were 3.86 and 2.43, respectively. The highest TBARS value was also obtained from Taraxacum officinate(0.18) at 4 weeks after storage, indicating the plant had the strongest antioxidant activity during long time. Even though TBARS value (0.18) in Taraxacum officinate sample showed lower in all plants than two synthetic antioxidants(0.05-0.09), antioxidant activities of the plants were much higher than that of a control (1.01). The results suggest that the plants have antioxidant potential as an alternative natural antioxidant based on natural plant resources.

This study was conducted to investigate the anti-oxidative, anti-oxidative and tyrosinase inhibitory effects of MeOH 80% extract and hexane, chloroform, ethyl acetate, butanol and aqueous fraction on three kinds of compositae plants in Korea. In the antimicrobial effect, the extract and chloroform fraction of Eclipta prostrata and hexane fraction of Carpesium abrotanoides L. and chloroform fraction of Siegesbeckia glabrescens exhibited significant inhibition. The antioxidant activity of ethyl acetate and butanol fractions was more than 90% in all three plants. In case of tyrosinase activity, showed a potent inhibition ethlyacetate fraction of Siegesbeckia glabrescens and Carpesium abrotanoides L, which were higher than control group. In MeOH 80% extracts, there was not found to have antimicrobial, anti-oxidant and tyrosinase inhibitory activity, however there was ethylacetate fraction of Siegesbeckia glabrescens to show effectss commonly in the three assay system.

This study was designed to examine the effects of Compositae plants on plasma glucose and lipid levels in streptozotocin (STZ) induced diabetic rats. Sprague-Dawley rats were randomly assigned to 5 groups: normal, STZ-control and three experimental groups [Artemisia iwayomogi (A. iwayomogi), Atractylodes lancea (A. lancea), and Taraxacum mongolicum (T. mongolicum)]. Normal and STZ-control group were fed an AIN-93 diet and three experimental groups were each fed a modified diet containing 10% compositae powder for 4 weeks. The plasma glucose levels at 4 weeks of A. iwayomogi, A. lancea, and T. mongolicum groups were significantly lower than STZ-control group. The A. iwayomogi and A. lancea groups had significantly suppressed hypertrophy of liver and kidney. The hematocrit levels of A. lancea and T. mongolicum group were significantly lower than STZ-control groups. The total cholesterol and triglyceride levels and atherogenic index (AI) of A. lancea group were significantly lower than STZ-control group. Intake of Compositae plants may be effective in antihyperglycemia by lowering blood glucose levels. The A. iwayomogi, A. lancea, and T. mongolicum can be beneficial for the diabetic complications and damage from the lipid peroxidation.

From the ethanol extract of the leaves of Artemisia selengensis a new sesquiterpene endoperoxide, bisabolene-2,5-endoperoxide, has been isolated. The structure of the peroxide was established on the basis of spectroscopic evidence.

The diethylet er fraction from the leaves extract of Ligularia fischeri var. spiciformis (Compositae) was subjected to silica gel column chromatography and yielded three new terpenoids named spiciformisin a (1), spiciformisin b (3), and monocyclosqualene (2). Acyclic diterpenes, spiciformisin a and -b, were established as 3,7,11,15-tetramethyl-1,3(20)-hexadecadiene and 3,7,11,15-tetramethyl-1,3,6,10,14-hexadecapentaene (IUPAC), respectively. A monocyclic triterpene, monocyclosqualene, were determined as [3,8,12,16,16-pentamethyl-(3,7,11,15-hexadecatetraenyl)]-3,3,5-trimethyl-1-cyclohexene. The structures were determined on the basis of NMR and MS analysis. Spiciformicin b showed potent cytotoxicity ($IC_{50},{\;}<9.7{;\}{\mu\textrm{g}}/ml$ against HL-60) in contrast to no cytotoxicity ($IC_{50},{\;}>200{\;}}{\mu\textrm{g}}/ml against HL-60 cells) of spiciformicin a with a cis-conjugated dienyl diexomethylene.
