In this study, the chemical constituents of bulb from Lilium lancifolium and Lilium tsingtauense were investigated. The content of moisture, crude protein and fiber of bulb from L. tsingtauense was higher than that of L. lancifolium, whereas the content of crude ash and nitrogen free extract of bulb from L. lancifolium was higher than that of L. tsingtauense. HPLC analysis revealed that total free sugar and amino acid content of bulb from L. tsingtauense was higher than that of L. lancifolium. There was no remarkable difference in proximate composition between the two species. The content of p-coumaric acid and ferulic acid was 1.93 mg% and 0.25 mg% in ethyl acetate fraction of L. lancifolium, on the other hand, 2.94 mg% and 0.46 mg% in ether fraction of L. tsingtauense. These results suggest that the bulb of L. tsingtauense can be considered as promising oriental medicine resource likewise L. lancifolium.

Plant regeneration system from zygotic embryos (2n=24) of Lilium lancifolium Thunb. via bulblet formation was estabished. Zygotic embryos of Lilium lancifolium formed bulblets and somatic embryos simultaneously when they cultured on MS medium supplemented with low concentration of 2,4-D. The highest frequency of bulblet and somatic embryo formation from zygotic embryos of Lilium lancifolium was 66.7% and 56.7%, respectively. The frequency of bulblet and somatic embryo formation was decreased when they cultured on MS medium over than 1 mg/L of 2,4-D. To regenerate whole plants, somatic embryos formed on zygotic embryos were transferred to MS basal medium. However somatic embryos did not fully converted into plantlets. Further incubation in the light, elongated somatic embryos formed numerous bulblets at the base of somatic embryos. Upon transfer to MS basal medium, bulblets were successfully converted into plantlets after further 4 weeks of culture in the light. After acclimatization, plantets from bulblets were transferred to soil and grown to normal plants in growth chamber (approximately $30\;{\mu}mol\;m^{-2}s^{-1}$, 16/8h photo period, $25^{\circ}C$) The chromosome analysis revealed that plants regenerated from zygotic embryos showed 2n=24. These results indicate that chromosome stability of source tissue is maintained during plant regeneration via bulblet formation.

To improve transformation efficiency, the callus of Lilium lancifolium Thunb. were bombarded by particles coated with pIG 121 Hm which include NPT II and GUS genes, and then cocultivated with Agrobacterium tumefaciens EHA101 which contain pIG121Hm binary vector, carrying neomycin phosphotransferase (NPT II) and $\beta$-Glucuronidase (GUS) genes. Three days after cocultivation with Agrobacterium tumefaciens and particle bombardment, the callus clusters were transferred to MS medium containing 1mg/L 2,4-D, 0.1mg/L BAP, 100mg/L kanamycin and 200mg/L carbenicillin. Four weeks after transfer to the selection medium, GUS expression was detected and PCR analysis revealed the presence of NPT II fragment of the expected size (700 bp) in the transformed callus. The GUS expression from Agrobacterium-mediated transformants after particle bombardment increased to over 3-folds compared with that of callus cocultivated with Agrobacterium tumefaciens without particle bombardment. The callus clusters containing kanamycin resistant gene were transferred to MS medium containing 1mg/L NAA and 1mg/L BAP. Somatic embryos were developed in four weeks and microbulbs expressing GUS were formed.

This study was performed to investigate the effects of various media compositions in regeneration of Lilium lancifolium. The adventitious bud initiation from microscale was the best on MS medium supplemented with BAP 1.0 mg/L and NAA 0.1 mg/L after 4 weeks of culture. However, from bulbscales, adventitious bud initiation was the best in dark condition on MS medium supplemented with BAP 0.5 mg/L and NAA 0.1 mg/L. On the other hand, callus induction was found to be the best from the microscales incubated in complete dark condition for 8 weeks on MS medium supplemented with 2,4-D 1.0 mg/L and BAP 0.1 mg/L. The highest plantlet regeneration from callus was obtained after incubation in the light condition for 8 weeks on MS medium supplemented with NAA 0.5 mg/L and BAP 0.1 mg/L. Rooting of shoots was obtained easily on MS medium and the plantlets were transferred to soil pots after 8 weeks. The chromosome analysis of the root tip cells was revealed that the callus-derived plantlets had normal chromosome number, 2n=24. No variation was observed in the morphology of the plantlets.

Lilium lancifolium (LL) is widely cultivated in East Asia and used to attenuate airway diseases. Our current study aimed to investigate the therapeutic effect of LL on pain level and inflammatory response in a rat model of monosodium iodoacetate (MIA)-induced osteoarthritis (OA). We first examined the effect of LL on inflammatory cytokines and inflammatory mediators in IL-1β-treated HTB-94 cells. The LL extract was found to significantly inhibit the levels of Interleukin-6 (IL-6), Interleukin-8 (IL-8), and prostaglandin-E2 (PGE-2) in Interleukin-1 β (IL-1β)-stimulated HTB-94 cells in a dose-dependent manner. Moreover, chronic oral administration of LL effectively restored the weight-bearing distribution in the rat model of MIA-induced OA. In addition, administration of LL inhibited inflammatory cytokines and inflammatory mediators, such as C-reactive protein (CRP), IL-6, leukotriene B4 (LTB-4), PGE-2, and matrix metalloproteinase-9 (MMP-9). Our findings collectively suggested LL as one of the potential therapeutic agents for OA, owing to its properties of reducing pain and inflammatory responses.

In this study, Lilium sp. were separated into bulbs, leaves, and flowers. Then, total polyphenol contents, electron donating ability (EDA), superoxide dismutase (SOD)-like activity, hydroxyl radical scavenging activity, and antimicrobial activity were measured from the extracts of each of the three aforementioned parts. The examination of physiologically active substances in the three parts revealed that Lilium davidii leaves had high total polyphenol contents, SOD-like activity, hydroxyl radical scavenging activity, and EDA, while the flowers of L. lancifolium showed high SOD-like activity, hydroxyl radical scavenging activity, and EDA, as well as a high level of total polyphenols in the bulb. Measurements of the antimicrobial activities of the extracts against Gram positive bacteria revealed that the leaves and flowers of L. davidii and L. lancifolium caused Bacillus subtilis and Salmonella enteritidis to form clear zones greater than 10 mm. Furthermore, the flowers of L. lancifolium showed particularly high antimicrobial activity against B. subtilis, and the flowers of L. davidii had high activity against S. enteritidis. For the Gram negative bacteria, the leaves and flowers of L. davidii and L. lancifolium caused Listeria monocytogenes and Escherichia coli to form clear zones greater than 10 mm, and finally, the flowers of L. davidii and L. lancifolium showed high antibacterial activity, with inhibition exceeding 12 mm.

Lilium lancifolium, which is one of the Korean native lilies, possesses several useful genetic characteristics such as growth vigor, bulbil formation and resistance to Fusarium. Hybridization was performed to insert useful traits of Asiatic hybrid "Dreamland" as the male parent with upward direction and dark brown spotless on the petal into L. lancifolium as the female parent. The rate of pollen germination of L. lancifolium and "Dreamland" were 30% and 60%, respectively. The pollen germination ratio of $F_1$ progenies at flowering date was 25-57%, which is between the parents'pollen germination ratio. The individual flowering time was between 113 days and 131 days after planting. Of 99% of all plants, the leaf shape index was more than five, which means that the leaf shape of $F_1$ plants is more influenced by female than male parent. The flower color was separated into four types. 51.5% of the progenies showed orange and 44.2% showed light orange, respectively. The colors seemed to be highly influenced by female parents. Mixed colors of parents, orange yellow and light yellow orange, were 3.1%, 1.2%, respectively. Flowering directions were segregated by three different ways, upside, side, and downside. Side direction, which is medium type between female and male parent, was 73%. All progenies showed lots of spot on petals except one offspring. The percentage of bulbil formation on leaf axil was 49.4%. Among those, the maximum number of bulbil formation was 25. The mean number of bulbil formation per plant was five.

This study was carried out to develop a new traditional alcoholic beverage by using lily scale in order to utilize lily scale as a new matter for nutritious foods. The condition of alcohol fermentation was investigated by the addition of 2.5, 5.0, 7.5, 10.0, 12.5 and 15.0% dried lily scale and 10, 20, 30, 40 and 50% raw lily scale into mash, respectively. The maximum amount of ethanol was produced when 15% dried lily scale and 20% raw lily scale were added to cooked rice at $25^{\circ}C$ for 10 days. In overall acceptability of sensory evaluation, the LSD-5 alcoholic beverage (added 5% dried lily scale into mash) and LSR-20 alcoholic beverage (added 20% raw lily scale into mash) showed the best acceptability. Physiological functionalities of LSD-5 and LSR-20 alcoholic beverage were investigated. Electron donating ability by DPPH solution ($16.5{\sim}23.2%$), SOD-like activity ($20.4{\sim}24.7%$), ACE inhibitory activity ($24.7%{\sim}78.2%$) and tyrosinase inhibitory activity ($57.4{\sim}62.6%$) of LSD-5 and LSR-20 alcoholic beverage were better than the control (non-added liquor). Moreover, acceptability and physiological functionalities of LSD-5 alcoholic beverage are better than LSR-20.
