Solvent-extracted volatile components from dry powder prepared from Citrus unshiu products such as immature Citrus unshiu (PCU), mature Citrus unshiu (MCU), Citrus unshiu peel (CUP), and citrus juice processing wastes (CJPW), were examined. Also, solvent-extracted volatile components from mushroom mycelia of Pycnoporus coccineus (PC), Lentinus edodes (LE), Pleurotus eryngii (PE), Hericium coralloides (HC), Panellus serotinus (PS), and Ganoderma lucidum(GL), all cultivated using citrus pulp solid media, were assayed. Twenty-nine volatile components were identified in dry powder prepared Citrus unshiu and 18 volatile components were characterized from mushroom mycelia. Of these, ${\beta}-elemene$, germacrene-D, and ${\delta}-cadinene$, were derived from CJPW, but caryophyllene, hexadecanoic acid, decanoic acid, and tetradecanoic acid were synthesized by mushroom mycelia.

This study was carried out to investigate the volatile flavor compounds of Pinus densiflora Sieb & Zucc according to extraction solvents and steam distillation method. The research results are as follows: 29 kinds of components were extracted by extraction solvents. Hydrocarbon was the major flavor components of the Pinus densiflora Sieb & Zucc. When the flavor components were extracted by solvents and analyzed by GC-Mass, in the hexane, ${\alpha}$-pinene was the highest and the contents ${\beta}$-thujene, trans-caryophyllene, ${\beta}$-mercene, ${\beta}$-cubebene were higher; in the ethyl acetate, the ${\alpha}$-cubebene content was the highest and the contents ${\alpha}$-cubebene, 3,6,9,12,15-pentaoxanonadecan-1-ol, camphene were higher; in the ethanol, the ${\beta}$-D4-tetrahydropyran was the highest and the contents ${\gamma}$-cadinene, 3-ethyl-1,4-hexadiene, ${\alpha}$-cubebene were higher. When the volatile constituents were extracted by steam distillation method, 44 kinds of components were extracted. Hydrocarbon was the major flavor components of the Pinus densiflora Sieb & Zucc. The ${\beta}$-cubebene content was the highest and the contents trans-caryophyllene, 2-hexenal, T-muurolol, ${\delta}$-cadinene were higher. This fact indicated that volatile constituents differ depending upon the extracting solvents and method.

In order to reconstruct the traditional technology of Korean golden varnish(Hwangchil) made from the exudates of D. morbifera, this study in the second step was carried out to analyze the chemical composition and oil properties of the exudates for coatings and bark extractives made from the trees of D. morbifera more than 20 years old grown in Wando and Jejudo islands in the southwestern part of Korean peninsula according to the physiological seasons. The results obtained are as follows: 1. The exudates appeared to be a phytoalexin because it exudated after several days in tapping only in summer season. 2. Both the exudates and bark-extracts with acetone contained 50~60% unsaponifiables and 30~50% saponifiables 3. A major component of essential oil in bark-extractives was ${\beta}$-cubebene and reached to 60~80%, while that of exudates included only 34% ${\beta}$-cubebene and some other compounds such as ${\beta}$-cadinene of 12%, aromadendrene of 9%, ${\beta}$-selinene of 9%, CAS030021-74-0 of 10%, etc. in GC-MS spectrometer. 4. A mjor component of fatty oil fraction in bark-extractives was linoleic acid and reached to more than 60%, while the exudates had mostly other components such as terpenes and phenolics instead of fatty acids accordint to GC-MS spectrometer. 5. Iodine value of samples after oil refining had 214mg/g in the exudates and more than than 150mg/g in bark-extractives, so the latter belonged to a drying oil.. 6. Therefore, the exudates from D. morbifera for traditional Korean golden varnish seems to have beeen used to a good varnish because it has some specific compounds different from its bark-extractives or general varnishes.

The composition of the essential oil of Ligustrum japonicum leaves was determined by GC-MS analysis. The major constituents of L. japonicum leaf oil were germacrene D (40.50%), ${\alpha}$-pinene (13.63%), (-)-${\beta}$-elemene (6.42%), ${\beta}$-caryophyllene (5.73%), and $\delta$-cadinene (5.47%). The acaricidal activities of L. japonicum oil were evaluated against acaridae and pyroglyphid mites. In the fumigant bioassay, the $LD_{50}$ values of L. japonicum oil were 16.48, 12.38, and $15.63{\mu}g/cm^3$ against Tyrophagus putrescentiae, Dermatophagoides farinae, and D. pteronyssinus, respectively. In the contact bioassay, the $LD_{50}$ values of L. japonicum oil were 8.02, 5.02, and $7.67{\mu}g/cm^2$ against T. putrescentiae, D. farinae, and D. pteronyssinus, respectively.

The aim of this study was to investigate the terpenoids of Total Volatile Organic Compounds (VOCs) released during drying of Cryptomeria japonica using the thermal extractor (TE). Considering the drying process of C. japonica, temperatures of TE were set at $27^{\circ}C$, $60^{\circ}C$, $80^{\circ}C$, $100^{\circ}C$, and $120^{\circ}C$, respectively. As the result, the emission factors of VOCs and terpenoids were increased as temperature increased. The amount of terpenoids included in VOCs emission factors were 87.5%, 81.6%, 83.6%, 90.1%, and 97.3% depending on above temperatures, respectively. Especially at$100^{\circ}C$ and $120^{\circ}C$, the amount of terpenoids were measured more than 90%. ${\delta}$-cadinene was the highest yield at each temperature and 32 types of terpenoids were collected. Emitted terpenoids were classified into the sesquiterpene group which consists of 15 carbon sources. These 32 sesquiterpenes were used for determining the useful bioactivity such as antifungal activity by the agar dilution. As the result, they showed the antifungal activity against Trichophyton rubrum, Trichophyton mentagrophytes, Microsporum gypseum. The 5,000 ppm concentration of terpenoids showed a strong activity with 100% against the 3 fungi. At the 1,000 ppm concentration of terpenoids, the antifungal activities against three fungi were 95.2%, 98.7%, and 97.3%, and their activities were a little inhibited at 100 ppm concentration.

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.
