Saussurea lappa Clarke is a well-known transitional medicine in Asia including Korea, China and Japan. It has been reported that Clarke has diverse effects such as anti-viral, anti-inflammatory, anti-cancer in human gastric cells and human prostate cancer cells. However, the anti-cancer effects and the mechanism of actions of Saussurea lappa Clarke are still unknown in breast cancer. In this study, we observed that Saussurea lappa Clarke inhibits the cell growth in a dose- and time-dependent manner in highly-metastatic MDA-MB-231 breast cancer cells. In order to examine whether Saussurea lappa Clarke suppresses cell growth inducing apoptosis cell death or cell cycle arrest, we analyzed DNA contents and cell cycle distribution using a flow cytometer and western blotting in MDA-MB-231 cells. We suggest that Saussurea lappa Clarke dose not induced apoptosis and induced G2/M phase cell cycle arrest. Moreover, Saussurea lappa Clarke also decreased the expression level of metastasis-angiogenesis releated protein such as VEGF. However, dose not changed the expression level of metastasis related protease MMP-1 in highly-metastatic MDA-MB-231 breast cancer cells. Therefore, Saussurea lappa Clarke might be good and useful chemotherapy agent highly-metastatic breast cancer patients.

This study was performed to investigate the potential use of Saussurea lappa C.B. Clarke as a source of antioxidant agents. Various solvent fractionates from S. lappa C.B. Clarke roots were investigated for their anti-oxidative effectiveness. The contents of total phenolics and flavonoids were determined by the Folin-Ciocalteu's colorimetric and the aluminum nitrate method, respectively. Total phenolic and flavonoid contents of n-butanol soluble fractionates from S. lappa C.B. Clarke, 44.43 ${\mu}g$ gallic acid equilibrium (GAE)/g extract and 92.15 ${\mu}g$ quercetin equilibrium (QE)/g extract, respectively, were higher than those of other solvent fractionates. The n-butanol soluble fractionates of S. lappa C.B. Clarke (1,000 ppm) showed the strongest inhibitory potential on 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical and reducing power at 92.98% and 0.38, respectively. Thus, our data shows that the S. lappa C.B. Clarke plant may help prevent antioxidative stress.

We investigated the total phenolic and flavonoid contents and the antimicrobial activity of ethanol extracts obtained from Saussurea lappa C.B. Clarke. The ethanol extracts of S. lappa C.B. Clarke were fractionated with various solvents (n-hexane, chloroform, and n-butanol). The antimicrobial activity of S. lappa C.B. Clarke was examined by disc-diffusion and micro-dilution susceptibility assays with six food-borne pathogens, and compared to that of the synthetic antibiotics. It is found that the S. lappa C.B. Clarke ethanol extract and n-hexane fraction have strong activity against B. cereus and V. parahaemolyticus strains compared to ampicillin. The inhibitory concentration ($IC_{50}$) values of hexane fraction against L. monocytogenes, B. cereus, and B. subtilis were 62.5, 250 and 500 ppm, respectively. Therefore, these data suggest that S. lappa C.B. Clarke may be useful as antimicrobial agents against food-borne pathogens.

The volatile flavor compounds of Saussurea lappa C.B. Clarke, a perennial, aromatic and medicinal herbaceous plant of the Asteraceae family, were isolated by the hydro distillation extraction method using a Clevenger-type apparatus, and analyzed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC/MS). The plant yielded a light yellow colored oil (0.02%, v/w). From S. lappa C.B. Clarke root oil, sixty-three volatile flavor compounds were tentatively identified, among which sesquiterpene was predominant (21.70%). The identified compounds of the root oil constituted 87.47% of the total peak area. From the constituents making up more than 5% of the volatile flavor components, a long-chain aldehyde, (7Z, 10Z, 13Z)-7, 10, 13-hexadecatrienal, was the most abundant volatile flavor compound (21.20%), followed by dehydrocostuslactone (10.30%) belonging to sesquiterpene lactone, valerenol (5.30%) and vulgarol B (5.06%).

The root of Saussurea lappa includes sesquiterpene lactones such as costunolide and dehydrocostus lactone, and has been shown to be anti-tumorigenic with being used in traditional medicinal therapy in the Eastern Asia. However, the molecular basis of the effects of Saussurea lappa on fate of gastric carcinoma, which incur very frequently in the area, has not been well identified. In this study, the cytostatic effects of Saussurea lappa were examined using gastric AGS cancer cells. Cell viability was dramatically reduced by Saussurea lappa, in a dose-dependent manner. As time passed after its treatment, apoptotic population was increased and clearly showed G2-arrest. Being consistent, its treatment resulted in maintaining of G1 and S-phase cyclins D1, E, and A even until a significant apoptotic population was observed, for example, at 24h after treatment. However, G2/M phase cyclin B1 was reduced even at 12 h after treatment. In addition, its treatment increased expression of p53, p21/sup Wafl / cyclin dependent kinase inhibitor (CKI), and Bax, resulted in cleavages of procaspase 3 and poly ADP-ribose polymerase(PARP), indicating that such G2 arrest- and apoptosis-related molecules are involved. Therefore, these suggest that extracts of Saussurea lappa root may be a safer and effective reagent to deal with gastric cancers either by traditional herbal therapy or combinational therapy with conventional chemotherapy.

Costunolide is an active sesquiterpene lactone isolated from the root of Saussurea lappa Clarke and is known to exhibit a variety of biological activities, including anti-carcinogenic and anti-inflammatory effects. Nevertheless, the pharmacological pathways of costunolide have not yet been fully elucidated. In this study, its cytotoxic effects were examined using AGS gastric cancer cells. Its treatment resulted in apoptosis in a dose- and time-dependent manner. The effects were attributed to the regulation of pro-apoptotic molecules and suppression of anti-apoptotic molecules. These results suggest that costunolide may be a candidate to deal with gastric cancers by chemopreventive agents.

Saussurea costus (Falc.) Lipchitz syn S. lappa C. B. Clarke (commonly known as 'Kuth') belonging to the family Asteraceae is a well known medicinal plant which finds wide usage in different indigenous systems of medicine of India, China, Korea & Tibet. In different folk medicines the roots of S. costus are used to treat various disorders like ulcer, stomachache, malaria, leprosy, dysentery and toothache. However due to over exploitation, it has become endangered and has become the concern of different governmental bodies in India. The increasing demand of this endangered Himalayan species has resulted in a situation where it is often substituted, knowingly or unknowingly, by other morphologically similar species. Arctium lappa, belonging to the same family, is one such plant that has often been found to be present in the market samples of 'Kuth'. The present study was thus carried out and morphoanatomical characters, physicochemical as well as chemical parameters were developed for proper identification of roots of S. costus and its differenciation from A. lappa as well as authentication of the commercial market samples. The detailed morphoanatomical studies revealed that roots of S. costus can be distinguished from A. lappa on the basis of some important microscopial characters eg. the schizogenous resin ducts observed in roots of S. costus, were absent in A. lappa.. Besides, the HPTLC fingerprint profile showed a distinct band at Rf. 0.72 in S. costus, which was totally absent in A. lappa and a band at $R_f$ 0.64 in A. lappa which was absent in S. costus Chlorogenic acid, used as a chemical marker for HPTLC analysis, was estimated to be 0.077% in S. costus as compared to 0.107% in A. lappa. Thus these detailed pharmacognostical parameters can be successfully used to distinguish between roots of S. costus and A. lappa.

Isolation and quantitative determination of costunolide from Saussurea lappa Clarke (Compositae) has been conducted by using HPLC method. Costunolide in an acetone extract from the crude drug was separated on a RP-18 column using a $MeOH-H_20$ mixture (65:35) as an eluent and the average content is about $1.32{\sim1.42%.$ The content of costunolide in dried extract was decreased by about 24% in seven days. However it showed a slight decrease in solution. It is highly recommended that quantitative determination of costunolide from Saussureae Radix should be conducted as early as possible after solvent extraction.

In this study, we experimented the influence of three herbal medicines, which are Saussurea lappa Clarke, Poncirus trifoliata Rafin, Citrus aurantium Linne, which are called 'Yigiyak(理氣藥)' on drug metabolizing enzyme cytochrome P450 3A4 in Human Liver Microsome. Above all, the reason for this study is that herbal medicines can be assumed that herbs might have interactions with drugs, other herbs, alcohol and chemicals whether those are much better synergy effects than expected effects when the medicine was treated alone or not. As a result, we showed that all of five traditional herbal medicines had no CYP 3A4 inhibition effect on 10, 20, 30, 40, $50{\mu}g/m{\ell}$ doses in Human Liver Microsome even Saussurea lappa Clarke showed a little inhibition as about 93% and 79% inhibition rate of control. However, this result are mostly not enough to prove that SLC has a CYP 3A4 inhibition effect. Moreover, it is not that those rates showed that those herbal medicines have CYP 3A4 induction effect. In conclusion, the result could support that those herbal medicines are more safe than chemical drugs even if this is the basic step to prove that result. Therefore, more specific studies to support this result, which are Kinetic study, cell and animal study then finally until clinical research, are required.
