The purpose of present study is to clarify the differences between EIslwitzia Ciliata (Thunb.) Hylander(향유) and Elsholtzia splendens Nakai ex F. Maekawa (꽃향유) for standardization and the proper usage as medicinal herbs. The major ingredients of both species were isolated by distillation and extraction. The qualitative and quantitative analyses of major distillates were carried out by the use of GC/MS. There was a significant difference between the components of Elsholtzia ciliata and Elsholtzia splendens in the aspects of major components. Several common ingredients were identified as linalool, cumene, elsholtzia ketone, naginata ketone isomer, naginata ketone, myristicin, and sesquiterpene alcohol. Comparison between Elsholtzia. ciliata and Elsholtzia splendens was done in the aspect of major compounds. Myristicin (33.7%) has been shown to be the major component in Elsholtzia ciliata whereas naginata ketone isomer (26.1%) was believed to be a major ingredient in Elsholtzia splendens. The elsholtzia ketone was also one of the major differentiating factors between Elsholtzia splendens and Elsholtzia ciliata, and the quantity is 15.1% in Elslwltzia splendens compared to 2.87% in Elsholtzia ciliata. Moreover, in the Elsholtzia splendens, 4- vinylguaiacol and isoosmorhizole were absent, but both compounds were present in the EIsholtzia ciliata.

Elsholtzia splendens Nakai has been used in North-East Asia as an ingredient of folk medicines for treating cough, headache and inflammation. The present investigation was carried out to establish its in vivo anti-inflammatory activity using several animal models of inflammation and pain. The 75% ethanol extract of the aerial part of E. splendens significantly inhibited mouse croton oil-induced, as well as arachidonic acid-induced, ear edema by oral administration (44.6% inhibition of croton oil-induced edema at 400 mg/kg). This plant material also showed significant inhibitory activity against the mouse ear edema induced by multiple treatment of phorbol ester for 3 days, which is an animal model of subchronic inflammation. In addition, E. splendens exhibited significant analgesic activity against mouse acetic acid-induced writhing (50% inhibition at 400 mg/kg), while indomethacin (5 mg/kg) demonstrated 95% inhibition. E. splendens ($5-100{\;}{\mu}g/mL$) significantly inhibited $PGE_2$ production by pre-induced cyclooxygenase-2 of lipopolysaccharide-treated RAW 264.7 cells, suggesting that cyclooxygenase-2 inhibition might be one of the cellular mechanisms of anti-inflammation.

Essential oil components were analysed in forty seven individual plants of Elsholtzia splendens collected from eight different regions in Korea to identify their chemotypes. Major oil components of chemotype 1 was dihydrotagentone (75%) and naginataketone and elsholtziaketone were not detected at all. Chemotype 2 was naginataketone (NK) type which content was more than 60%. Chemotype 3 had more than 60% of elsholtziaketone (EK) as major volatile oil. EK type and NK type plants selected were maintained stably in their progenies after seed generation. Naginatketone and elsholtziaketone had functional properties such as antioxidation and antibacteria.

From 2006 to 2007, the stem rot of Elsholtzia splendens Nakai caused by Sclerotium rolfsii occurred sporadically in an herbs exhibition at Gyeongsangnam-do Agricultural Research and Extension Services, Korea. The typical symptom is water-soaking, dark brown on the stem and rotting, wilting and blighting. The infected plants were mostly died. White mycelial mats were spread over lesions, and then sclerotia were formed on stems and near soil line. The sclerotia were globoid in shape, $1{\sim}3$ mm in size and white to brown in color. The optimum temperature and sclerotia on PDA was $30^{\circ}C$ and the hyphal width was $4{\sim}9{\mu}$. The typical clamp connections were observed in the hyphae of the fungus grown on PDA. On the basis of mycological characteristics and pathogenicity to host plants, this fungus was identified as Sclerotium rolfsii Saccardo. This is the first report on the stem rot of E. splendens caused by S. rolfsii in Korea.

This study was carried out to find the possibility of use of Solid Phase Microextraction (SPME) for extracting the volatile aroma compounds in the five aromatic plants (Agastache rugosa O. Kuntze, Mentha arvensis Linne, Thymus quinquecostatus Celakovsky, Elsholtzia splendens Nakai, Schizonepta tenuifolia Briquet) belongs to the Labiatae. In the result of the analysis, the volatile aroma compounds were mainly composed monoterpene alcohol (linanol, menthol, ${\alpha}-terpineol$, borneol), monoterpene ketone (limonene, menthone) and sesquiterpene (trans-caryophyllene,${\delta}-cadinene)$. The volatile aroma compounds of Agastache rugosa O. Kuntze and Mentha arvensis Linne were extracted by SPME more identified than the SDE. However, Schizonepta tenuifolia Briquet more identified by the SDE and in Elsholtzia splendens Nakai similar to the SDE. Especially, the SPME showed the sesquiterpene contents was more than the SDE. The major volatile aroma compounds were difference but the composition of those between the SPME and the SDE showed no difference. Within the results, the SPME showed the most convenient and a rapid extraction method to analysis of the volatile aroma compounds.

Objective : We try to find out the literature and clinical evidences of seasonal formula through the analysis of the addition and subtraction of medical herbs in the formula according to the season. Method : In this study, we analyzed 122 seasonal prescriptions from "Dong-uibogam(東醫寶鑑)", "Bang-yakhappyeon(方藥合編)", "Jeongchijunsueng(證治準繩)", "Dangyesimbeop(丹溪心法)", "Uihakimmun(醫學入門)", "Uihakjeongjeon(醫學正傳)", "Gyeong-akjeonseo(景岳全書)" and "Taepyeonghyeminhwajegukbang(太平惠民和劑局方)". Results : In spring, pungent-warm herbs such as the dried rhizome of cnidium officinale Makino, the dried root of SEdebouriella divaricata (Turcz.) Schischk. are used. In summer, bitter-cold such as the dried root of Scutellaria baicalensis Georgi, the dried rhizome of Coptis chinensis Franch. or pungent herbs such as the dried aerial part of Elsholtzia splendens Nakai, the dried ripe seed of Dolichos lablab L. are added. In fall and winter, pungent-bitter-hot herbs such as the dried ripe fruit of Evodia rutaecarpa Benth., the dried rhirome of Zingiber officinale Rosc. are used. Conclusions : In this paper, we have shown that several medical herbs could be added and subtracted in the formula according to the season because they have the seasonal characteristic Gi or treat seasonal pathogens.
