This study extracted essential oil from the native Korean plant Valeriana fauriei and performed fragrance component analysis, antioxidant (DPPH, ABTS), cell viability (MTS), and anti-inflammatory (Nitric oxide) experiments based on the analysis results. The fragrance component analysis revealed that the major effective component of Valeriana fauriei, bornyl acetate, was present at a high content of 47.88%, compared to other regions. Additionally, patchouli alcohol (18.9%), camphene (11.37%), α-Pinene (5.44%), and D-limonene (1.11%) were identified. The antioxidant activity showed that the DPPH radical scavenging activity was 73.62% at 250 µl/ml, and the ABTS radical scavenging activity was 82.17% at 250 µl/ml. At a concentration of 5 µl/ml, which did not exhibit cytotoxicity, the NO production inhibition rate decreased by 62.02% compared to the control group. Through these findings, the potential for the application of Valeriana fauriei essential oil in functional products has been scientifically validated, contributing to research utilizing Valeriana fauriei essential oil.

This study was conducted to compare fragrance and volatile chemicals of essential oils in Gom-chewi (Ligularia fischeri) and Handaeri Gom-chewi (Ligularia fischeri var. spicifoprmis). Essential oils were extracted by steam distillation of leaves of Gom-chewi (GC) and Handaeri Gom-chewi (HGC), after which samples were collected by solid-phase micro extraction and the compositions of the essential oils were analyzed by gas chromatography-mass spectrometry (GC-MS). The yields of the essential oils in GC and HGC were 0.12% and 0.04%, respectively, and the threshold levels of the essential oils in GC and HGC were 0.01% and 0.1%, respectively. There were 19 constituents of the essential oil of Gom-chewi: 14 carbohydrates, 4 alcohols, and 1 acetate, and the major constituents were L-${\beta}$-pinene (36.02%), D-limonene (25.64%), ${\alpha}$-pinene (24.85%) and ${\beta}$-phellandrene (5.39%). In the essential oil of HGC, 25 constituents were identified: 17 carbohydrates, 4 alcohols, 3 acetates, and 1 N-containing compound, and the major constituents of HGC were D-limonene (39.74%), L-${\beta}$-pinene (35.43%) and ${\alpha}$-pinene (11.94%). The minor constituents of HGC were ${\rho}$-cymene, ${\gamma}$-muurolene, ${\gamma}$-cadinene, germacrene D, ingol 12-acetate and butyl 9,12,15-octadecatriene and nimorazole were not identified in the GC essential oil. Overall, the results showed that the fragrance and chemical compositions of essential oils in GC and HGC differed, suggesting that both essential oils could be used for the development of perfumery products.

The paper is an attempt to explore various aspects of Thai traditional cake culture in order to understand the characteristics of Thai tradition cakes and their significance in Thai cultural life. The study will focus on cake culture in both folk culture and court culture as well as observe the changes of this culture in the present time of globalization. In the text book on Thai Khanom, Kobkhaew Natpinit sums up the characteristic of Thai traditional 'Khanom' as follows: 1. Thai traditional (cake) Khanom are mostly made from rice, sugar and coconut. 2. The tastes of Thai Khanom are sweet and rich in coconut cream with a little bit of salty taste to enhance the flavour of coconut. 3. The colour and scents of Thai Khanom are naturally fragrant. Fresh fragrant flowers are used to add pleasing fragrance and colour to Thai Khanom.

A fast and simple sampling and sample preparation device, (NTD) has been developed and applied to sample and analyze volatile components from ground coffee beans. Coffee fragrances and other volatile organic compounds (VOCs) were sampled by the NTD and then analyzed by gas chromatograph-mass spectrometry (GC/MS). Divinylbenzene (DVB) particles (80/100 mesh size) were the sorbent bed of the NTD. More than 150 volatile components were first identified based on the database of the mass library and then finally 30 fragrances including caffeine were further confirmed by comparing experimental retention indices (i.e. Kovat index) with literature retention indices. Total sampling time was 10 minutes and no extra solvent extraction and/or reconstitution step need. Straight n-alkanes (C6-C20) were used as retention index probes for the calculation of experimental retention indices. In addition, this report suggests that an empty needle can be an alternative platform for analyzing polymers by pyrolysis-GC/MS.

Methanol extract (1.0 wt%) of Scutellaria baicalensis George satisfied preservation standard of CTFA (The Cosmetics, Toiletry, and Fragrance Association) against Staphylococcus aureus, Pseudomonas aeruginosa, Candida albicans and Escherichia coli which were inoculated in skin lotion. Even at a low concentration (0.01 wt%) the extract showed high superoxide dismutase-like activity. The CTFA standard could also be satisfied for the above four strains when methanol extract of Liriope platyphylla were combined with the 1.0 wt% extract of S. baicalensis George. This result suggests that extract of L. platyphylla does not hinder the preservation activity of S. baicalensis George. Moreover, skin moisture content could be maintained for 6 hours after the application of a cream containing the extract of L. platyphylla.

The present study was designed to evaluate central inhibitory effects of an essential oil from Acori graminei Rhizoma (AGR), the dry rhizomes of Acorus gramineus Solander (Araceae) upon fragrance inhalation (aroma therapy). Preinhalation of an essential oil of AGR markedly delayed the appearance of pentylenetetrazole-induced convulsion. Furthermore, the inhalation of an essential oil of AGR impressively inhibited the activity of ${\gamma}$-aminobutyric acid (GABA) transaminase, a degradating enzyme for GABA as inhalation period is lengthened.

The problem of detecting individual differences of chemically similar liquids remains to be unsolved for various areas of the natural sciences, such as medicine, biology, nutrition, and cosmetics 1. This problem is of crucial importance for the cosmetic sciences, including perfumery and aromatherapy. For example, some certain subtle differences of smell and taste between chemically similar liquids are very difficult to detect by using conventional methods of analysis, such as gas chromatography (GC) and the like (except under unique advanced techniques that are expensive, time consuming, and are not readily available). However, a trained human nose and! or mouth of a perfumer and/ or taster can detect differences of that kind. There are two conventional ways to make a fragrance.(omitted)

The purpose of this study was to explore consumer behavior of perfume products. Data were collected through 7 focus group interviews with 33 female consumers whose ages ranged between the 20's and 40's. According to analysis of groups divided by age and frequency of use, some group differences were found in information source, purchase place, consideration factors, fragrance preference, etc. The study results indicated that perfume consumption behaviors could be explained in part by the innovation adoption and communication theories. Especially, relative advantage, compatibility, observability, and trialability were important factors influencing consumers' adoption of new perfume. Also, many respondents used perfume as a tool to present their own image and identity, as well as to send messages regarding their mood and condition to others.
