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.

약용식물인 천궁(Cnidium officinale Makino)의 미활용 부위의 생리활성 탐색을 위한 기초연구로서, 천궁 지상부(잎과 줄기)를 ethyl acetate, methanol, 물의 3가지 용매로 추출한 후, paper disc method와 microtiter broth dilution method를 이용하여 항균활성을 측정하였다. 천궁 지상부 ethyl acetate 추출물과 methanol 추출물은 비교적 높은 항균활성을 보였으며, Gram 양성균, Gram 음성균, 그리고 효모 등에 대해 broad한 항균범위를 지닌 것으로 나타났다. 특히 ethyl acetate 추출물은 0.4 mg/disc의 농도에서 Staphylococcus aureus, Salmonella typhimurium, Listeria monocytogenes등의 식중독균에 대해 각각 9.7 mm, 9.2 mm, 10.0 mm의 억제환을 보였다. Saccharomyces cerevisiae에 대한 항진균활성은 물 추출물과 유기용매 추출물에서 확인되었다. 그러나 물 추출물의 항균 및 항진균 활성은 유기용매 추출물에 비해 현저히 낮아 비교적 높은 농도에서 항균효과가 나타났다. 천궁 지상부 ethyl acetate 추출물의 항균활성은 사용 농도와 균의 종류에 따라 다른 것으로 나타났으며, 0.5 mg/mL의 농도에서 Staphylococcus aureus와 Pseudomonas aerogenes의 생육은 완전히 저해되었으나, 0.25 mg/mL 이하의 농도에서는 생육억제효과가 감소하는 것으로 나타났다. Enterobacter cloacae는 0.5 mg/mL의 추출물 처리에 의해 생육이 2 log cycle정도 억제된 반면, Escherichia cole는 비교적 저항성이 강한 것으로 나타났다. 천궁의 ethyl acetate 추출물은 열에 매우 안정하여 $100^{\circ}C$ 30분 또는 $121^{\circ}C$에서 15분간의 열처리(autoclave)에 의해서 항균활성이 감소되지않는 것으로 나타났다. 따라서 약용으로 이용되고 있는 천궁의 근경 이외의 미활용자원인 잎과 줄기 등의 지상부위를 이용한 천연 항균소재 개발이 가능할 것으로 판단된다.
