In order to obtain basic data for utilization of the aerial parts of Cnidium officinale Makino (APCO), the antioxidant properties of the aerial parts and rhizomes of C. officinale were measured using DPPH and ABTS radicals, and nitrite scavenging assays. The ethyl acetate (EA) fraction prepared from the aerial parts of APCO showed the strongest antioxidant activities, and contained high level of total phenolic compounds (325.81 mgTE/g) and flavonoids (259.16 mgRE/g). The concentrations for 50% reductions ($RC_{50}$) values of the DPPH and ABTS radicals, and nitrite by the EA fraction of APCO were $11.27\;{\mu}g/m{\ell}$, $14.34\;{\mu}g/m{\ell}$, and $10.26\;{\mu}g/m{\ell}$, respectively. APCO exhibited approximately 3-9 times higher antioxidant activity than rhizomes of C. officinale. The antioxidant capacities of APCO were positively correlated with its total phenolic contents. Therefore, it was concluded that the aerial parts of C. officinale can be a useful and cost-effective source of natural antioxidant for food or cosmetics.

Background: Measurement of chlorophyll fluorescence (CF) is useful for detection the ability of plants to tolerate environmental stresses such as drought, and excessive sunlight. Cnidium officinale Makino is highly sensitive to water stress and excessive sunlight. In this study, we evaluated the effect of soil water and shade treatment on the photosynthesis and leaf temperature change of C. officinale. Methods and Results: C. officinale was cultivated under uniform irrigation for 1 week drought stress (no watering) for 6 days. A significant decrease in CF was observed on the 5th day of withholding water (approximately 6% of soil water content) regardless of shading. Notably, the Rfd_lss parameter (CF decrease rates) with and without shade treatment was reduced by 73.1% and 56.5% respectively, at 6 days compared with those at the initial stage (0 day). The patterns of the degree of CF parameters corresponded to those of the soil water content and difference between leaf temperature (Ts) and air temperature (Ta). Meanwhile, CF parameters recovered to the 3 - 4 days levels after re-watering, while the soil water potential was completely restored. The suitable soil water content for C. officinale optimal growth was between -5 kPa and -10 kPa in this experiment. Conclusions: Lack of soil water in the cultivation of C. officinale, even with shading, decreased latent heat cooling through transpiration. As a result, heat dissipation declined, and the plant was subjected to drought stress. Soil water content plays a major role in photosynthesis and leaf temperature in C. officinale.

Psoriasis is an auto-immune skin disease, which is characterized by the excessive generation of plaques on the skin with typically a long-lasting red, itchy and scaly symptoms. Imiquimod, which has been used for the treatment of external genital warts, actinic keratosis, and superficial basal cell carcinoma, induced of psoriasis-like skin disorders with skin erythema and thickness in mice. In the present study, we tried to find the bioactive herbal extract against imiquimod-induced psoriasis-like skin disorder in mice. During the searching of the herbal extract with anti-psoriatic effect, the ethanolic extract of Cnidium officinale ameliorated imiquimod-induced psoriasis-like skin disorder in mice. The morphological evaluation, H&E staining and Psoriasis Area and Severity Index (PASI) score showed that ear and back thickness, and erythema induced by imiquimod were significantly reversed after the treatment of the cream of the ethanolic extract of C. officinale. The overexpressed myeloperoxidase (MPO) and keratin 6A levels were decreased by the treatment of C. officinale cream. Also, $IFN-{\gamma}$, c-fos and $I{\kappa}B-{\alpha}$ mRNA levels, which are related to the progression of psoriasis, were reduced by C. officinale cream. Thus, the ethanolic extract of C. officinale ameliorated psoriasis-like skin disorder induced by imiquimod and might be the therapeutic agent for psoriasis.

Dendritic cells (DCs) play a pivotal roles in the initiation of T cell-mediated immune responses, making them an attractive in immuno vaccines. Angelica gigas and Cnidium officinale were a medicinal herb widely used in Asian countries. In this study, we examined the effects of A. gigas and C. officinale extracts on the DCs functional maturation and phono-type. Immature DCs were cultured in the presence of GM-CSF and IL-4, and the generated immature DCs were stimulated with OVA in the presence or absence A. gigas and C. officinale extracts, respectively, for 24 hours. The antigen-presenting capacity of A. gigas and C. officinale extracts-treated DCs as analyzed by $CD4^+$ helper T cell clone (OVA-specific) proliferation and cytokines (IL-2 and $IFN-{\gamma}$) production were significantly increased. But A. gigas and C. officinale extracts were not directly effected $CD4^+$ helper T cell clone function. Also, the expression of surface co-stimulatory molecules, including major histocompatibility complex (MHC) class II, CD86 and CD11c, is increased on DCs that were stimulated with A. gigas and C. officinale extracts. These results indicate the immunomodulatory properties of A. gigas and C. officinale extracts, which might be medical supplies or health foods.

This study was carried out to investigate the usefulness of the aerial part of Cnidium officinale Makino as a bioactive material source. The aerial part(leaf and stem) of Cnidium officinale Makino was extracted with three kinds of solvents and determined their antimicrobial activities against several bacteria and yeast strains using the paper disc method and the microtiter dilution method. The extracts of the Cnidium offocinale aerial part exhibited the broad spectrum of antibacterial activity against Gram (+) and Gram (-) bacteria, including food-borne pathogens such as Listeria monocytogenes, Salmonella typhimurium, and Staphylococcus aureus. The extracts of Cnidium officinale also showed antifungal activity against Saccharomyces cerevisiae. The ethyl acetate extracts completely inhibited the growth of Staphylococcus aureus and Pseudomonas aerogenes, and moderately inhibited the growth of Escherichia coli and Enterobacter cloacae at the concentration of 0.5 mg/mL. However, water extract of Cnidium officinale exhibited lower antimicrobial activity than ethyl acetate and methanol extracts. The inhibitory effect of the ethyl acetate extract of Cnidium officinale Makino was not destroyed by heating at $100^{\circ}C$ for 30 min or at $121^{\circ}C$... for 15 min. These results suggest that the aerial part of Cnidium officinale Makino could be a useful source for a natural antimicrobial material.

This study investigated the acaricidal and repellent activities of various plant extracts and Cnidium officinale-derived materials against Haemaphysalis longicornis. Among the 24 methanolic plant extracts, C. officinale showed the highest acaricidal activity (93.3%) against H. longicornis. Platycodon grandiflorus, Phytolacca americana, Magnolia denudata, Houttuynia cordata, C. officinale, and Pueraria montana showed significant differences in their repellent activity. Consequently, the activity of solvent-fractionated materials and the derived material of the C. officinale, was investigated and a 90% acaricidal effect was observed three days after hexane fraction treatment, indicating that the repellent response was statistically significant. Butylidenephthalide, which is a C. officinale-derived compound, showed 90% acaricidal activity seven days after treatment. Additionally, all H. longicornis moved to the untreated area in the t-tube olfactometer experiment, confirming the repellent activity of butylidenephthalide. Therefore, the results of this study suggest the use of C. officinale crude extract and butylidenephthalide as potent acaricidals and repellents against H. longicornis, respectively.
