Chinese crude drug 'Se Sin'(細辛)has been used to cure headache, cough and expectorant. To the botanical origin of 'Se Sin', Zhong-yao-zhi(中葯志) reported Asarum heterotropoides var. mandshuricum. A. sieboldii and A. sieboldii var. seoulensis, and Zhong-yao-da-ci-dian(中葯大辭典) reported Asarum heterotropoides var. mandshuricum and A. sieboldii of Aristolochiaceae. In Korea, this crude drug has been used as a Korean folk remedy for tothache and aromatic. The botanical origin of 'Se Sin' is considered to be Asarum species of Aristolochoaceae. But there has no pharmacognostical confirmation on it. To clarify the botanical origin of 'Se Sin', we studied on the anatomical characteristics of Asarum species growing wildly in Korea i.e. A. maculatum, A. sieboldii, A. sieboldii var. seoulensis, and of 'Se Sin' from Korea on Korean market. Through our studies, the botanical origin of 'Se Sin' from Korea was proved to be whole plant of Asarum sieboldii and A. sieboldii var. seoulensis.

Asarum sieboldii has been used for treatment of fever, pain, common cold, and chronic sinusitis in Korea. In this study, we performed quantification analysis of seven major constituents including aristolochic acid I, aristolochic acid II, ${\alpha}$-asarone, ${\beta}$-asarone, elemicin, methyl eugenol, and safrole in the 70% ethanol extract of Asarum sieboldii and its solvent fractions, n-hexane, ethylacetate, n-butanol, and water ones using a ultra-performance liquid chromatography-electrospray ionization-mass spectrometer(UPLC-ESI-MS) and gas chromatography-mass spectrometer(GC-MS). Regression equations of seven components were acquired with $r^2$ values >0.99. The values of limit of detection(LOD) and quantification(LOQ) were 0.1-3.9 ng/mL and 0.3-11.7 mg/mL, respectively. The amount of the seven compounds in Asarum sieboldii were not detected -143.66 mg/g. The established LC-MS/MS and GC-MS methods will be helpful to improve quality control of Asarum sieboldii.

Taxonomic treatment and the identification key for 6 species and 4 varieties from the genus Asarum (Aristolochiaceae) in Korea were presented on the basis of the morphological analyses. Recently the taxonomy of the genus Asarum in Korea is controversial in the definition of species and the establishment of variation range. Our morphological studies supported that the species A. patens, A. misandrum and A. versicolor should be recognized as independent species by the unique morphological characters such as calyx lobes, stylar protuberance and leaf variegation. Second, A. sieboldii var. cornutum, A. koreanum, A. maculatum and A. sonunsanense, regarded as species or variety by different scholars, showed a close relationship with A. sieboldii by the similar calyx characters. Thus, new combinations, such as A. sieboldii for. cornutum, A. sieboldii for. koreanum, A. sieboldii for. maculatum and A. sieboldii for. sonunsanense, are proposed. And A. heterotropoides var. seoulense and A. heterotropoides var. mandshuricum also had a close relationship, thus, new combinations, A. mandshuricum for. seoulense, A. mandshuricum for. mandshuricum, are proposed. Furthermore, it is appropriate that A. heterotropoides var. heterotropoides, only distributed in Japan, is revised into A. heterotropoides as independent species by the unique character from the 2 varieties above. Consequently, the genus Asarum in Korea is classified into 3 species and 7 forma.

Cathamus tinctorius, Coptis japonica and Asarum sieboldii were tested as substrate for the production of Flammulina velutipes. Among the C. tinctoris , C. japonica and A. sieboldii , C. tinctoris was the best substrate for the production of fruitbody. The effects of addition of C. tinctoris to sawdust substrate resulted in the increased mycelial growth on inoculum culture, 3.1% in ratio of fully culture and shorted one day in culture period. C. tinctoris was decreased 6.1% in ratio of fully culture, 11.0% in ratio of fruitbody productive culm. The addition of C.tinctoris, C.japonica to sawdust substrate increased 134.6%, 114.1% on the yield of the mushroom fruitbody respectively . But A. sieboldii decreased the mycelial growth and pineheading ratio delayed the production of fruitbody.

Root of Asarum sieboldii has been used in chinese medicine. It was been known that the extract of A. sieboldii has medicinal effect such as antifebrile, anodyne, and anti-inflammatory. Antifungal activity of the essential oil extracted from A. sieboldii against various epiderman and opportunistic human pathogenic fungi was investigated. Steam-distillated essential oil demonstrated very high antifungal activity against Aspergillus fumigatus, Aspergillus niger, Cryptococcus neoformans, and Candida albicans. MIC (minimum inhibitory concentration) of the essential oil against C. albicans was 5 ul/ml, indicating that the essential oil may be used as natural preserves for cosmetic and nutritional products.

Background: To investigate the possibility of using Asarum sieboldii as an environment-friendly fumigant for protecting organic cultural heritages, the inhibitory effect of A. sieboldii extract against wood rot fungi on Hanji was examined. Methods and Results: The physical, optical, and morphological properties of Hanji inoculated with Trametes versicolor and Tyromyces palustris, and exposed to the n-hexane fraction of A. sieboldii extract, were measured. The physical properties were expressed as weight loss, zero-span tensile strength and viscosity and the optical properties were depicted by luminance and chromaticity ($L^*$, $a^*$, and $b^*$). The results showed that, the n-hexane fraction of A. sieboldii extract inhibited the growth of fungi on Hanji, and preserved its condition. At a concentration of 25 mg, the n-hexane fraction of A. sieboldii extract maintained zero-span tensile strength, increased viscosity, and restricted discoloration of Hanji. It also was confirmed that the weight of fungi infested Hanji exposed to the extract did not decrease. Scanning electron microscopic images revealed that the spores and hyphae of T. versicolor and T. palustris were not present on Hanji during treatment with > 25 mg of the n-hexane fraction of A. sieboldii extract. Conclusions: These results indicate that the n-hexane fraction of A. sieboldii extract by virtue of its antifungal effectiveness may help in preserving Korean paper cultural heritages, including Hanji.

Asarum sieboldii Miq. (Aristolochiaceae) is a perennial herbaceous plant and has been used as traditional medicine for treating diseases, cold, fever, phlegm, allergies, chronic gastritis, and acute toothaches. Also, it has various biological activities, such as antiallergic, antiinflammatory, antinociceptive, and antifungal. However, the anticancer effect of A. sieboldii have been rarely reported, except anticancer effect on lung cancer cell (A549) of water extracts of A. sieboldii. This study investigated the anticancer activity of methanol extracts of A. sieboldii (MeAS) and the underlying mechanism in human FaDu hypopharyngeal squamous carcinoma cells. MeAS inhibited FaDu cells grown dose-dependently without affecting normal cells (L929), as determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide and live and dead assay. In addition, concentration of MeAS without cytotoxicity (0.05 and 0.1 mg/mL) inhibited migration and colony formation. Moreover, MeAS treatment significantly induced apoptosis through the proteolytic cleavage of caspase-3, -7, -9, poly (ADP-ribose) polymerase, and downregulation of Bcl-2 and upregulation of Bax in FaDu cells, as determined by fluorescence-activated cell sorting analysis, 4'6-diamidino-2-phenylindole stain, and western blotting. Altogether, these results suggest that MeAS exhibits strong anticancer effects by suppressing the growth of oral cancer cells and the migration and colony formation via caspase- and mitochondrial-dependent apoptotic pathways in human FaDu hypopharyngeal squamous carcinoma cells. Therefore, MeAS can serve as a natural chemotherapeutic for human oral cancer.

To search for anit-H5N1 influenza virus agent, the anti-viral activity of methanol and aqueous extracts from thirty medicinal plants were examined in this study. The plant material (30 g) was extracted with methanol (300 mL) for 24 hr at room temperature. Methanol extracts were filtered and evaporated, then freeze-dried. Aqueous extracts were prepared with dried plant material (30 g) and hot distilled water (300 mL). After 3 hr, the aqueous extracts were filtered and evaporated, then lyophilized. Extracts prepared from different plants were tested the antiviral activity against influenza viruses [A/vietnam/1194/04 (H5N1)-NIBRG-14] using the hemagglutination (HA) assay. Among the test plants, Asarum sieboldii was found to be a potent inhibitor of H5N1 influenza virus in MDCK cell culture. Virus titers were 7 log, whereas with methanol extract of Asarum sieboldii for 48 hr titers were 3 log, indicating that methanol extract of Asarum sieboldii inhibited the H5N1 influenza viruses from the infected cells.
