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.

The chromatographic separation of the MeOH extract of the aerial parts from Aster hispidus (Compositae) led to the isolation of eight compounds. Their structures were established by spectroscopic methods to be ${\beta}-amyrin$ (1), oleanolic acid (2), (2R)-1, 2-O-(9Z, 12Z, $15Z-dioctadecatrienoyl)-3-O-{\beta}-D-galactopyranosyl\;glycerol$ (3), trans-phytol (4), 9, 12, 15-octadecatrienoic acid (5), kaempferol (6), 3,5-dicaffeoyl quinic acid (7), 3,4-dicaffeoyl quinic acid (8) and kaempferol-3-O-rutinoside (9). Compounds 1, $3{\sim}6$ and 9 showed non-specific moderate cytotoxicity against five human tumor cell lines $(5.44{\sim}23.51\;{\mu}g/ml)$. The other compounds were of marginal activity against tested five human cancer cell lines $(9.05{\sim}>30.0\;{\mu}g/ml)$.

Lactuca raddeana (Compositae) is used to treat obesity and complications due to diabetes. The five phenolic compounds including chlorogenic acid, chicoric acid, luteolin 7-O-glucoside, luteolin 7-O-glucuronide, luteolin were qualitatively identified by LC-ESI-MS analysis. The contents were quantitatively determined by HPLC, under the condition of a Capcell Pak C18 column ($5{\mu}m$, $250mm{\times}4.6mm\;i.d.$) and a gradient elution of 0.05% trifluoroacetic acid (TFA) and 0.05% TFA in $MeOH-H_2O$ (60 : 40). The contents of chicoric acid (100.99 mg/g extract) and luteolin 7-O-glucoside (101. 69 mg/g extract) were high, while those of other three phenolic substances were very low. The 3T3-L1 adipocyte cells treated with chicoric acid and luteolin 7-O-glucuronide significantly suppressed the accumulation of fat, suggesting they are effective against obesity. Since high level of peroxynitrite (ONOO) causes cardiovascular disease in obese patients, its scavenging activity was also studied.

The compositional analysis and the peroxynitrite ($ONOO^-$) scavenging assay were undertaken to demonstrate beneficial dietary effect of lettuce (Lactuca sativa L., Compositae). Quinic acid derivatives of the seven cultivars were qualitatively and quantitatively analyzed by HPLC to lead to the finding of 3,4-di-O-caffeoyquinic acid and 3-O-p-coumaroylquinic acid and their contents ranged over 2.72-4.47 mg/g and 8.97-23.26 mg/g, respectively. A cultivar Hacheong had the highest quantity of quinic acid derivatives. The peroxynitrite scavenging effect of the five cultivars (Jangsu, Gosina 27, Gopung, Yeolpungjeogchima, and Mipungjeogchugmyeon) were ranged over 7.45-8.26${\mu}g$/ml as $IC_{50}s$ while those of Hacheong and Mihong had less effect ($IC_{50}$ >10 ${\mu}g$/ml).

Aucklandia lappa Decne (Compositae) has been used for treatment of vomiting, diarrhea, abdominal pain and indigestion and Inula helenium L. (Compositae) for sweat and urination. In spite of difference species and efficacy, we have been used Aucklandia lappa Dence together with Inula helenium L. To distinguish Aucklandia lappa Dence from Inula helenium L., we have compared the contents of dehydrocostuslactone and costunolide by HPLC. The average contents of costunolide of Aucklandia lappa Dence was 0.84% $({\pm}\;0.29)$ but was not detected in Inula helenium L. The contents of dehydrocostuslactone from Aucklandia lappa Dence and Inula helenium L. were about 1.70% $({\pm}0.37)$ and 1.82% $({\pm}0.59)$, respectively.

To find the anti-Alzheimer's activity of Cacalia hastata var. orientalis (Compositae), caffeoylquinic acids were analyzed in this plant by HPLC and the inhibitory activities of the extract on cholinesterases including acetylcholinesterase (AChE) and butyrylcholinesterse (BChE) and peroxynitrite ($ONOO^-$) were assayed. Sum of caffeoylquinic acids in the 80% MeOH extract was quantitatively higher in leaves (35.8% of the extract) than in stems (3.7%). The compound, 3,5-dicaffeoylquinic acid, was contained in the highest amount in the leaf (44.32 mg/g dry weight). The $IC_{50}s$ of the 80% MeOH extract were shown to be $67.45{\mu}g/ml$ for AChE, and $8.59{\mu}g/ml$ (for $ONOO^-$), respectively, suggesting that the leaves would have the anti-Alzheimer's activity due to the high content of caffeoylquinic acids.

태백산맥에서 발견된 Saussurea속의 신식물을 태백취(S. grandicapitula)로 기재하였다. 우리나라 특산인 본 종은 크기가 70-100cm에 달하는 장대한 식물로, 잎 뒷면이 창백한 녹색이며, 적갈색의 얽힌 털이 엽병에 나고, 수개의 두화가 짧은 화경에 달리며, 구형의 커다란 총포에는 갈색의 얽힌 털이 밀생하고, 포편은 뒤로 젖혀지기도 하는 특징을 가져서, 한반도 북부나 일본의 다른 종들과는 명확히 구별된다. 이는 태백산맥의 눈 많은 환경에 적응 진화한 종으로 생각된다.

The chromatographic separation of the hexane soluble fraction of the methanol extract of the aerial parts of Solidago virga-aurea var. gigantea Mo. (Compositae) led to the isolation of a new benzylbenzoate (1) together with four known benzylbenzoates (2-5). Their structures were determined as 2-methoxybenzyl-2-hydroxybenzoate (1), benzyl-2-hydroxy-6-methoxy­benzoate (2), 2-methoxybenzyl-2,6-dimethoxybenzoate (3), 2-methoxybenzyl-2-methoxy-6­hydroxybenzoate (4), and benzyl-2,6-dimethoxybenzoate (5). Their structures were established by spectroscopic methods. Biological effects of compounds, 1 and 2, were investigated in vitro usingherapeutic agents by stimulating macrophage functions, with potential use in the treat­ mouse peritoneal macrophages. The benzylbenzoates (1 and 2) could serve as immunotherapeutic agents by stimulating macrophage functions, with potential use in the treatment of infectious diseases.
