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.

This study was conducted to investigate the composition of flavor components of Elsholtzia ciliata and Eisholtzia splendens in order to obtain basic informations for the application of tobacco and food industry. Flavor components extracted were divided into three fractions ; essential oil, absolute and oleoresin from E. ciliata and E. splendens. Essential oil was extracted by simultaneous steam distillation(SDE), absolute and oleoresin were extracted by $100\%$ n-hexane and $50\%$ ethanol, respectively. Yields of the essential oil, absolute and oleoresin fractions from E. ciliata were $0.34\%,\;11.34\%\;and\;15.24\%,$ and those from E. splendends were $0.28\%,\;12.45\%\;and\;9.95\%$, respectively. The major components of essential oil of E. ciliata were naginata ketone$(29.37\%)$, elsholtzia ketone$(14.37\%)$ and rosefuran$(11.76\%)$. The major components of essential oil of E. splendens were 2-cyclohexen-1-one$(26.81\%)$, elsholtzia ketone$(13.46\%)$ and naginata ketone$(5.26\%).$ The composition of flavor components showed a slight difference between essential oils of E. ciliata and E. splendens. The major components of absolute fraction from E. ciliata were linoleic acid$(12.07\%),$ palmitic acid$(10.46\%)$ and 2-cyclohexene-1-one$(5.39\%).$ And those from E. splendens were linoleic acid$(12.38\%),$ palmitic acid$(9.47\%)$ and naginata ketone$(8.86\%).$ Ethyl linoleolate was a major component in oleoresin of E. ciliata and E. splendens.

In this study, we evaluated anti-oxidation, whitening and anti-inflammatory effects of Elsholtzia ciliata extract for use as the cosmeceuticals. Elsholtzia ciliata extracts (30, 70 and 100% methanol extract) exhibited a significant tree radical scavenging effect (up to 80% over 0.025% concentration of 30 and 70% methanol extract, over 0.01% concentration of 100% methanol extract) against DPPH radical generation and showed a significant inhibitory effect (up to 80% over 0.1% concentration) on melanin synthesis in B-16 Melanoma cells. We separated 4 fractions from Elsholtzia ciliata extract (70% methanol extract) by MPLC. The 1st, 2nd, and 3rd fractions showed anti-oxidation (DPPH radical scavenging activity and suppressive effect on Mn-SOD), whitening(inhibitory effect on melanin synthesis) and anti-inflammatory (suppressive effects on $IL-1{\alpha}$, IL-6, COX-2, and total NO synthesis) effects.

The present GC-MS analysis elucidated the composition of the essential oil obtained from the herb of Elsholtzia ciliata(Lamiaceae). Overall, the content of monoterpenes was higher than that of sesquiterpenes. Monoterpenes rich in this oil were carvone (peak area, 26.180%), camphor (2.304%), borneol (9.974%), dihydrocarveol (3.296%), ${\alpha}$-citral (=geranial, 4.025%), geranic acid (2.961%), while sesquiterpenes occupying relatively higher percentage were ${\alpha}$-humulene (0.918%), (-)-spathulenol (0.974%), ${\alpha}$-caryophyllene oxide (2.014%), globulol (1.362%), ${\beta}$-caryophyllene oxide (0.750%). The components characterizing this oil were 1-octen-3-ol, acetophenone, and butylated hydroxytoluene. The $IC_{50}$ of this oil on acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) were $42.37{\mu}g/ml$ and $121.34{\mu}g/ml$, respectively, suggesting that the essential oil of E. ciliata may be active on the memory loss of patients suffering from Alzheimer's disease.

The essential oil fraction was extracted from the aerial parts of the plant by steam distillation method and its composition was analyzed by GC-MS (gas chromatography-mass spectrometry) which led to the identification of 43 compounds. Dehydroelsholtzia ketone (56.81%) and elsholtzia ketone (30.05%) were identified as the predominant components of this oil. The antibacterial activities of the essential oil fraction were assessed by micro-dilution tests against antibioticsusceptible and -resistant strains of Streptococcus pneumoniae, Staphylococcus aureus, Salmonella enteritidis, and S. typhimurium. The oil inhibited most of the tested strains significantly resulting MICs (minimum inhibiting concentrations) between 2 mg/ml and >16 mg/ml. In most cases of this study Streptococcus pneumoniae and Staphylococcus aureus showed higher sensitivity to this oil than Salmonella strains.

This study was to evaluate the biological activity of flavor components extracted from E. ciliata and E. splendens in order to survey the possibility applicable to tobacco and food industry. Flavor components were extracted with dividing into three parts; essential oil, absolute, oleoresin. In the nonenzymatic lipid peroxidation system, the inhibition rate($\%$) of essential oil were $67.3\;\pm\;20.7\%,\;58.1\;\pm\;19.3\%$ at the concentration of 50 ${\mu}g/mL$ of E. ciliata and E. splendens, respectively. The inhibition rate($\%$) of the oleoresin in E. ciliata was higher than one in E. splendens. In the enzymatic lipid peroxidation system, the inhibition rate($\%$) of essential oil and oleoresin was$14.28\;\pm\;2.38\%,\;and\;65.93\;\pm\;0.01\%,\;and\;was\;22.58\;\pm\;2.84\%\;and\;40.73\;pm\;6.04\%$. The oleoresin of two species were showed above $90\%$ of the inhibition rate($90\%$) against autooxidative lipid peroxidation system. $EC_{50}$ values in neutral red uptake assays 24 h of exposure times were $23.3\;{\mu}g/mL,\;341.0\;{\mu}g/mL\;and\;17.2\;{\mu}g/mL$ in essential oil, absolute and oleoresin from E. ciliata respectively, and were $46.4\;{\mu}g/mL,\;681.7\;{\mu}g/mL\;17.6\;{\mu}g/mL$ in three extractions of E. splendens. Oleoresin of two species showed high rate in the cytotoxic effect by neutral red uptake assay. Absolute and oleoresin did not show antibiotic and mutagenic activity. On the contrary, essential oil with over 500 ug/plate showed antibiotic and mutagenic activity in Ames test. Essential oil and oleoresin have a prolongating effect the ciliostasis of rat trachea. This results indicate that flavor components extracted from E. ciliata and E. splendens can be considered to be toxicological safe and to be the possibility applicable the cigarette, food and drug industry as a flavor for expectoration.

Schizonepeta tenuifolia (Korean name "Hyung- Gae") is an oriental medicinal plant that is widely used in Korea, China and Japan. S. tenuifolia (Hyung-Gae) has many pharmacological activities and is mostly used for many medicinal preparations. The dried aerial part (spikes and stems) of three oriental medicinal plants, S. tenuifolia (Hyung-Gae), Agastache rugosa (Kwhak-Hyang) and Elsholtzia ciliata (Hyang-Yoo) belonging to the same family, mint family Labiaceae, have such similar shape and smell that it is difficult to differentiate between them. The trnL-F regions of chloroplast DNA of the three medicinal plants were sequenced and used as targets in multiplex PCR reaction to identify S. tenuifolia. After alignment of trnL-F sequences of the authenticated plant samples, one single nucleotide polymorphism (SNP) specific to S. tenuifolia was found. Based on this SNP, a new primer was designed that specifically amplifies the trnL-F region of S. tenuifolia. The established multiplex-PCR was proven to be effective in the differentiation of commercial S. tenuifolia samples from A. rugosa and E. ciliata. This rapid and accurate molecular method is highly promising for use in the food industry.

Elsholtzia hallasanensis, E. springia, and E. splendens var. fasciflora (Lamiaceae) were reported recently as new species or new varieties of E. splendens according to their morphological characteristics. To reappraise the taxonomic status of these additional taxa and to determine the relationships between all Korean Elsholtzia taxa except E. saxatilis, which is distributed in North Korea, molecular studies based on the nrDNA (ITS) and cpDNA (rpl16, and trnH-psbA) sequences of seven taxa of Elsholtzia and one outgroup were carried out. The molecular data support that E. angustifolia and E. minima are distinct species from E. splendens and E. ciliata, respectively, because they have several private marker genes and show monophyly. The molecular data also support that E. splendens has a very close taxonomic relationship with both E. hallasanensis and E. springia. We found that E. splendens var. fasciflora, with multiple inflorescence, was based on several private marker genes and on the monophyly of its trees, suggesting that it can be considered as a variety. Elsholtzia springia, with the same sequences and the same morphological characteristics with E. hallasanensis after transplanting, should be treated as a synonym of E. hallasanensis. Moreover, we consider the taxonomic status of E. hallasanensis as E. splendens var. hallasanensis (Y. Lee) N.S. Lee & C.S. Lee, stat. nov.
