The germicidal and insecticidal properties of volatile components extracted from star anise(Illicium verum Hooker filius) and clove (Eugenia caryophyllata THUNBERG)were evaluated against five microorganisms and three insects for the purpose of developing biocidal active substances from medicinal plants. The volatile components of star anise and clove showed strong antimicrobial effect against Aspergillus niger, Penicillium funiculosum, Mucor hiemalis, Trichoderma viride, and Aureobasidium pullulans. The extracts of each medicine also showed insecticidal effects against Sitophilusoryzae L., Lyctus linearis GOZE, and Reticulitermes spertus kyushuensis Morimoto. Fumigant toxicities to adult insects were determined. In the case of fumiganttoxicity, the extract of star anise showed 100% mortality against R. spertus, S.oryzae, and L. linearis at rates of $2.5\mu\ell$, $50\mu\ell$, $250\mu\ell$/filter paper, respectively but showed no killing effects by clove. The volatile components of star anise and clove were investigated by means of GC/MS. The main constitute, anethole among 20components from star anise and eugenol among 9 components from clove were identified. The mixture of star anise and clove as the volume ratio of 2 : 1 showed higher properties for antimicrobial and insecticidal effect than each volatile component. A. niger was inhibited by the mixture(125ml/$m^3$) for up to 10 days of exposure. Also, from the result of observing state change of organic materials by volatile extracts of star anise and clove, volatile extracts effects have no effect on natural organic materials of organic cultural properties and can be used as biological control agent. As research contents as above, the insecticidal and germicidal agents from star anise and clove and the mixture of them were more efficient and high level to prevent biological damage for conservation of organic cultural properties. So they may be used in new development of biologicalinsecticidal and germicidal agents for conservation of cultural properties.

This study was carried out to investigate the biological activities of star anise extracts obtained from four different solvents (water, methanol, ethanol and chloroform) by measuring total polyphenol and flavonoid contents, DPPH radical scavenging, hydroxyl radical scavenging, nitrite scavenging activity and antimicrobial activity. The methanol extract showed the highest extraction yield, followed by ethanol, water and chloroform. The properties of the extracting solvents significantly affected the total polyphenol content. Methanol extracts contained more total polyphenols than any other extracts. The highest DPPH radical scavenging activity was found in methanol extract. The hydroxyl radical and nitrite scavenging activity were highest in methanol and ethanol extracts. In antimicrobial activity, water extract showed stronger activities than methanol and ethanol extract against Micrococcus luteus and Bacillus subtilis, and no inhibitory effects on Gram negative bacteria were found in all extracts at the concentration used.

Headspace solid phase trapping solvent extraction (HS-SPTE) and GC-MS was applied for the characterization of volatile flavors from fennel, anise seed, star-anise, dill seed, fennel bean, and Ricard aperitif liquor. Tenax was used for HS-SPTE adsorption material. Recoveries, precision, linear dynamic ranges, and the limit of detection in the analytical method were validated. There were some similarities and distinct differences between fennel-like samples. The Korean and the Chinese fennels contained trans-anethole, (+)-limonene, anisealdehyde, methyl chavicol as major components. The volatile aroma components from star anise were characterised by rich trans-anethole, (+)-limonene, methyl chavicol, and anisaldehyde. Additionally, principal component analysis (PCA) has been used for characterizing or classifying eight different fennel-like samples according to origin or other features. A quite different pattern of dill seed was found due to the presence of apiol (dill).

The purpose of this study was to analyze factors affecting acceptance of four kinds of dak-jjim samples in third year school-aged children (n=100). Soy sauce, red pepper paste, Vietnam fish sauce, and star anise were applied to samples for their familiar and exotic characteristics. Significant differences among samples were observed in odor, taste, and acceptance (p<0.001). Soy (Soy sauce sample), RPPaste (Red pepper paste sample), and Soy_FishS (Soy sauce and Vietnam fish sauce sample) samples scored higher than Soy_StarA (Soy sauce and star anise sample) sample. On the other hand, there were no significant differences in intensities of saltiness, sweetness, and hot spicy flavor (p>0.05). Liked attributes in samples were saltiness, sweetness, chicken flavor, potato flavor, moistness of chicken, hot spicy flavor, and color. Disliked attributes in samples were hot spicy flavor, saltiness, and ginger flavor. Significant differences among samples were observed in familiar intensity and willing to try again (p<0.001). Soy, RPPaste, and Soy_FishS samples scored higher than Soy_StarA sample. Panels considered taste (46%) and nutrition (45%). Higher familiar intensity of sample was associated with higher acceptance in samples. In other words, familiarity of food affects acceptance of food. Therefore, familiar ingredients such as soy sauce and chicken can be used for development of Korean menu items considering taste and nutrition with enhanced Korean food acceptance in school-aged children.

Skeletal muscle, essential for metabolism, thermoregulation, and immunity, undergoes myogenic differentiation that results in myotube formation. Trans-anethole (TA), the major constituent in essential oil produced by anise, star anise, and fennel, whose function in skeletal muscle has not yet been elucidated. Therefore, we investigated whether TA influenced muscle differentiation in mouse C2C12 myoblasts. Cells were induced to differentiate using a differentiation medium with or without TA (50 or 200 mg/mL) daily for 5 days. We measured myotube length and diameter after differentiation days 1, 3, and 5 and analyzed the expression of myogenic markers (myoblast determination protein 1, myogenin, myocyte enhancer factor 2, muscle creatine kinase, and myosin heavy chain) and atrophy-related genes (atrogin-1 and muscle ring finger-1 [MuRF-1]) using quantitative real-time PCR. Additionally, we observed the expression of total protein kinase B (Akt) and phosphorylated Akt (p-Akt) using western blotting. Our data showed that TA significantly induced the formation of smaller and thinner myotubes and reduced the myogenic factor expression. Furthermore, the atrogin-1 and MuRF-1 expression markedly increased by TA. Consistent with these findings, TA significantly decreased the expression of total Akt and p-Akt. Taken together, these results indicate that TA inhibits myogenic differentiation of C2C12 cells via reduction of both total Akt and p-Akt. Our findings may provide valuable insights into the impact of PAA on individuals at risk of muscle atrophy.

The superoxide dismutase(SOD)-like activities for 26 kinds of herbs and spices and 10 kinds of instant curry products were determined by measuring their abilites to reduce nitroblue tetrazolium. All samples showed the SOD-like activities. Rosemary, cassia, tarragon, allspice, oregano, bay leaves, basil, marjoram, thyme and star anise had higher activities than $10^5\;unit/g$ and clove had highest activity of $232,143{\pm}19.989\;unit/g$. The SOD-like activities for 10 kinds of instant curry products were in the range of $400{\sim}700\;unit/g$ when measured after heat treatment at $100^{\circ}C$ for 10 min. The water extracts of spices, herbs and curries were obtained by heat treatments of $25^{\circ}C$ for 60 min or $100^{\circ}C$ for 10 min, and their nitrite scavenging activity was measured at different pH conditions(1.2, 4.2 or 6.0). The nitrite scavenging activities were higher at acidic pH. However, the effects were not different from two heat treatments. The water extracts from cassia, bay leaves, allspices, oregano, staranise, rosemary, clove and tarragan had high nitrite scavenging activity(>90%) when they were measured at pH 1.2, and those from clove was highest $(97.58{\pm}0.88%)$. The pure curry used as raw materials for instant curry products had the nitrite scavenging activity in the range of $50{\sim}60%$ at pH 1.2 and the activity was not changed during the aging period$(0{\sim}12weeks)$. The ten brands of instant curry products had the nitrite scavenging activities of $12{\sim}28%$ at pH 1.2

An Electronic Nose(E-Nose) and Gas Chromatography/Mass Spectroscopy (GC/MS) are meanwhile conventional technique to analyze volatile materials in many industries (e.g., food, medicine, environment) and have broad acceptance in the analysis of tobacco products. In this study, an experiment where tin oxide gas sensor array responses and GC/MS profiles are used to characterize the volatile compounds of different cigarettes at the same time is performed and the measurements of two instruments are compared for cigarette samples with a known chemical information. E-Nose and GC/MS were employed to differentiate and match flavored cigarettes with commercial tobacco flavoring agents (lavender, vanilla, peppermint, orange, star anise). For verifying reliability of two systems, the analyses were conducted in terms of amount of flavors in each cigarettes using partial least squares (PLS) and with the principal components analysis (PCA). Various chemical sensors and GC/MS data was reduced into two principal factors (PC1, PC2) for being distinguished with visualized regions. Both systems provided adequate results for odor characteristics of cigarettes in this study with each instrument having its own advantages and disadvantages.

The sauce and paste, which is collectively called as 'jang' in Korean is the staple seasoning of Korean cuisine. Although China shares some aspects of the Jang (醬), the exact types and forms are different. In this study, we explore the current Korean jang through the six culinary books- "Seongwonlog (醒園錄)", "Yangsolog (養小錄)", "Jojeongjip (調鼎集)", "Susiggeeumsigbo (隨息居飮食譜)", "Junggwerok (中饋錄)", and "Sosigseolyag (素食說略)" from the Qing Dynasty of China. The Jang of Qing Dynasty are further classified into the Chumjang (甛醬), Dusi (豆豆支), Chungjang (淸醬), and jangyou (醬油). To make these four types, the huangzi (黃子) has to be first made from the flour or beans, after which salt is added and sun-dried. Chumjang is the type of Chunjang used to make Zhajiangmian and is widely used in the Northern part of China. Like Chumjang, Dusi is made from flour and beans. Salt as well as various spices like Star anise, Chinese pepper and sesame are added. This type of paste is widely used in the Southern part of China. Chungjang is made when salt and water are added and sun-dried, after which it is filtered through an apparatus called Jangyou. The final product is sauce similar to today's soybean sauce.

Headspace micro solid phase extraction using mulberry paper bag (HS-MPB-$\mu$-SPE) has been developed and validated for the analysis of volatile flavor compounds from five spice by gas chromatography-mass spectrometry (GC/MS). HS-MPB-$\mu$-SPE was performed with adsorbent particles enclosed inside a mulberry paper bag. Four different kinds of adsorbents such as Tenax TA, Porapack Q, dimethylpolysiloxane and polyethylene glycol were tested. The extraction solvents compared were petroleum ether, methylene chloride, and chloroform. Better results were obtained when Tenax TA and petroleum ether were used. The limit of detection (LOD) and the limit of quantitation (LOQ) were in the range of 1.3 ng/mL and 4.3 ng/mL, respectively, for o-cymene as a model compound of monoterpene. Proposed method showed good reproducibility (3.3%, RSD) and good recoveries (94.0%). The HS-MPB- μ-SPE is very simple to use, inexpensive, rapid, requires small sample amounts and solvent consumption. Because the solvent for extraction is reduced to only a very small volume (0.6 mL), there is minimal waste or exposure to toxic organic solvent and no further concentration step. This method allows successful characterization of the headspace in contact with the five spice sample. Strong trans-anethole from star anise or fennel is a characteristic flavor of five spice powders. HS-MPB-$\mu$-SPE combined with GC/MS can be a promising technique for the broad spectrum measurement of volatile aroma compounds from solid spices.
