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.

Objectives: Obesity is an important cause of insulin resistance that leads to obese type 2 diabetes. Recently it has been found that obesity is associated with adipose tissue accumulation which causes systemic inflammation. In this study, we investigated effects of Inula helenium on the inflammation in high fat diet-induced insulin resistance mouse. Methods: Insulin resistance was induced in C57BL/6 male mice (19~21 g) on a 60% fat diet. Mice were divided into 3 groups (n=6) of normal, control and Inula helenium. After 12 weeks, body weight, FBS, oral glucose tolerance test (OGTT), serum level of insulin, epididymal fat pad, liver weight and the gene expression of tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-6, interleukin (IL)-10 and cluster of differentiation (CD) 68 were measured. Also, adipose tissue macrophage was analyzed by fluorescence activated cell sorting. Results: Inula helenium significantly reduces oral glucose tolerance levels, insulin serum level and adipose tissue macrophage. Also Inula helenium increased IL-10 gene expression and decreased CD68 gene expression. Conclusions: These results show that Inula helenium has anti-insulin resistance and anti-inflammatory effects on a high fat diet-induced insulin resistance mouse model.

Inula helenium L. is rich source of eudesmane-type sesquiterpene lactones, mainly alantolactone and isoalantolactone, which have the various pharmacological functions. In this study, we examined the inhibitory effects of nitric oxide (NO) production of hexane, methylene chloride, ethyl acetate, butanol, and water fractions from I. helenium and investigated the anti-inflammatory effect of hexane fraction of I. helenium (HFIH) in LPS-induced RAW 264.7 cells. Quantification of alantolactone and isoalantolactone from HFIH was carried out for the standardization by multiple reaction monitoring using triple quadrupole mass spectrometer. HFIH significantly inhibited inducible NO synthase (iNOS) and cyclooxygenase-2 (COX-2) protein as well as their downstream products NO and prostaglandin $E_2$ ($PGE_2$) in LPS-stimulated RAW 264.7 cells. Moreover, HFIH suppressed $NF-{\kappa}B$ transcriptional activity by decreasing the translocation of p65 to the nucleus. The in vivo study further confirmed that HFIH attenuated the paw edema induced by carrageenan in an acute inflammation model. These findings suggest that HFIH may be useful as a promising phytomedicine for inflammatory-associated diseases.

The purpose of this study was to introduce the differential standard of Mok-Hyaeng Radix species. We established the classificatory standard according to the external and internal morphology and the pattern in 4 kinds of Mok-Hyaeng Radix. The results follow: 1. On the external morphology, Radix of Vladimiria souliei had a sticky material in the head of roots and it was yellowish white in the cut surface. It attached to teeth during chewing. Radix of Aucklandia lappa (=Saussurea lappa) was dark grayish brown and was grayish brown in the cut surface. It had special odor and was not attache to teeth chewing it. On the other hand, Radix of Inula helenium was dark brown. In the cut surface, cortical layer was different from wood layer. Radix of Aristolochia contorta was yellowish brown. In the cut surface, it was not smooth and cortical layer was different from wood layer. 2. On the internal morphology, Radix of Vladimiria souliei had many fascicular fibers and scattered large oil chambers in the bast ray, xylem ray, and parenchyma. On Radix of Aucklandia lappa (=Saussurea lappa), it was difficult to find out the trace when the cork layer was exfoliated. The cambium formed circle and the large oil chambers were scattered in the phloem and xylem. On the other hand, external cortical layer of Radix of Inula helenium was detached and cambium was formed to indistinct circle and large oil chambers were scattered in the phloem and xylem. On Radix of Arustolochia contorta, the large oil chambers were scattered in the surface later, bast part was relatively broad and cambium formed circle. 3. On the TLC pattern, Radix of Aristolochia contorta, Inula helenium, Aucklandia lappa, and Vladimiria souliei were chromogenic to violet and purple according to sulfuric acid colour pattern, especially faint on Aristolochia contorta. 4. On the pattern analysis of HPLC, we compared the content and the pattern of constunolide and dehydrocostus lactone, Radix of Aucklandia lappa was similar to Radix of Vladimiria souliei and Radix of Aristolochia contorta was similar to Radix of Inula helenium. On the total HPLC component pattern, constunolide and dehydrocostus lactone were similar in all four types, but it showed the Rf 5-6 peak was only in Radix of Aristolochia contorta, not in Radix of Inula helenium, Aucklandia lappa, and Vladimiria souliei. It is considered the results of this study will be furnished the basis to succeeding studies and it is needed to extensive comparative study for the same genus-degree of relatedness.

The oils of Acorus gramineus, Cinnamomum sieboldii, Eugenia aromatica, and Inula helenium were tested for their acaricidal activity against Dermatophagoides farinae and D. pteronyssinus. Responses varied according to dose and mite species. As compared to the oils, the oil most toxic to D. farinae and D. pteronyssinus was E. aromatica, followed by C. sieboldii, A. gramineus, and I. helenium. On the basis of $LD_{50}$ values of the oils in A. gramineus, C. sieboldii, and E. aromatica, the compound most toxic against D. farinae and D. pteronyssinus was eugenol congeners (isoeugenol>eugenol>acetyleugenol) followed by benzyl benzoate, salicylaldehyde, safro1, DEET, cinnamyl alcohol, and 3-carene. As a naturally occurring acaricide, these oils and eugenol congeners could be useful as new acaricidal agents against Dermatophagoides spp.

The anticancer effect of medicinal plants against two oral carcinoma cells, A253 and SCC-25 were investigated in this study. Methanol extracts from 63 medicinal plants, which have anticancer activities against other cancers such as stomach, hepatocellular or colon carcinomas, were prepared and screened for their anti- oral cancer activity by using MTT assay. Thirty one samples showed anti-oral cancer activity against either cell line used, however, other 32 samples had no anti-oral cancer activity. Among these samples methanol extract of Caesalpinia sappan revealed the strongest anti-oral cancer activity. The $IC_{50}$/ values of this extract against A253 and SCC-25 cells were 16 and 25 $\mu$g/m1, respectively. Fractions of n-hexane, dichloromethane, ethylacetate, n-buthanol and water were prepared from methanol extracts of Caesalpinia sappan, Anthriscus sylvestris, Rhus japonica, Curcuma arowatica, Inula helenium, Sinoarnudinaria reticulata, and Polygonum cuspidatum, respectively. Among these 35 fractions the n-hexane fraction of Inula helenium showed the strongest anti-oral cancer activity, the $IC_{50}$/ value was 1.6$\pm$0.3 $\mu\textrm{g}$/ml. Ten other fractions showed $IC_{50}$/ values lower than 10 $\mu\textrm{g}$/ml.

Premenstrual syndrome (PMS) is a common disorder affecting the emotional and physical health of women during certain periods of the menstrual cycle. Many researchers who have previously studied PMS have believed that PMS is associated with changes in sex hormones and serotonin levels at the beginning of the menstrual cycle. However, recent studies suggest that progesterone/estrogen imbalance and elevation of prolactin-induced by dopamine low-secretion play a crucial role in increasing PMS symptoms. Because of this, we have focused on mitigating PMS symptoms through the mechanism of prolactin secretion inhibition by dopamine receptor activation. The inhibition of prolactin secretion by 61-kinds of medicinal herb extracts was investigated in GH3 pituitary cells. Among them, Inula heleniun L. root extract (IHE) showed excellent prolactin secretion inhibitory effect. IHEs were prepared using 30, 50, and 70% ethanol. And the yield, cytotoxicity, dopamine receptor activity and inhibition of prolactin secretion of each extract were measured. Through a series of experiments, we found that prolactin secretion was significantly reduced (P<0.01) by the components present in IHE and that dopamine receptor regulation was possible (P<0.05). Considering yield and safety, we suggest the use of 30% ethanol IHE in the development of PMS symptom relief products.

The cytotoxic activities of the methanol extracts of 44 plant species in 31 families against five human solid A549 (lung), SK-OV-2 (ovarian), SK-MEL-2 (melanoma), XF-498 (central nervous system), and HCT-15 (colon) tumor cell lines were examined using the sulforhodamine B (SRB) assay. Responses varied with both cell line and plant species used. Potent cytotoxic activities ($ED_{50}$, <$40{\mu}g/ml$) against all model tumor cell lines were produced from the extracts of Rhus chinensis gall (Galla rhois), Betula platyphylla var. japonica bark, Inula helenium root, Cinnamomum cassia bark, Cinnamomum sieboldii root bark, Lysimachia davurica whole plant, and Evodia rutaecarpa fruit. These plants may be useful for developing new types of naturally occurring anti-tumor agents.
