Truffles are the fruiting bodies of ascomycete fungi that form underground. Truffles are globally valued, culturally celebrated as aphrodisiacs, and highly sought-after delicacies in the culinary world. For centuries, naturalists have speculated about their mode of formation, and in cultures surrounding the Mediterranean Sea, many species have been prized as a delectable food source. Truffle fruiting bodies form underground and emit a variety of volatile organic compounds (VOCs). Truffle volatiles are believed to have evolved to attract animals that disperse their spores. The main VOCs identified from truffles include sulfur compounds, such as dimethyl sulfide (DMS) and dimethyl disulfide (DMDS); in addition, 1-octen-3-ol and 2-methyl-1-propanol have been found in most truffle species. Humans use pigs and dogs trained to detect truffle VOCs in order to find these prized subterranean macrofungi. Truffles have pharmacological potential, but until more reliable cultivation methods become available their high price means they are unlikely to see widespread use as medicinals.

Forests are valuable natural resources for people living around the mountains. In particular, the comfortable feeling or healing is one of the most important benefits obtained from forests. This healing can be possible by many aspects of forests, including the landscape, natural sounds, anions, and pleasant aromas. We focused on the volatile organics from forest causing pleasant aromas, phytoncides. Twenty phytoncides were monitored from February to September in a national tree garden (BaekDoDaeGan SooMokWon). Five sites were monitored two times per month and 20 phytoncides were detected. Borneol showed the highest annual average concentration and the order of concentration was borneol > mycene > sabinene > limonene > α-pinene. The average phytoncide concentration was relatively high in spring and summer season when the trees were physiologically active. Daily monitoring showed that the afternoon hours had higher concentrations of phytoncides than the morning hours, which may be due to the stabilized atmospheric conditions at the sites. Among the five sites, coniferous forests gave higher phytoncide emissions than broadleaf tree forests. The current study showed that forests produce several phytoncides that cause a healing effect and a forest bath may be beneficial to the health of visitors to forests.

지리오갈피(Acanthopanax chilsanensis)를 이용한 지역특산품을 개발할 목적으로 먼저 지리오갈피 뿌리, 줄기 및 열매 자체에 대한 이화학적 성분분석을 행하였다. 지리오갈피의 일반성분을 분석한 결과 뿌리, 줄기 및 열매의 조지방은 각각 2.09, 2.51 및 7.94%이었으며, 조단백질은 11.50, 7.18 및 10.17%로 나타났다. 그리고 조회분은 각각 11.07, 6.85 및 6.38%로 뿌리 중의 조회분이 줄기와 열매 중의 조회분 보다 약간 높게 나타났다. 환원당은 각각 18.90, 10.70 및 24.05 g/100 g으로 측정되었다. 색도를 측정한 결과 명도(L)는 줄기가, 적색도(a)는 열매가, 그리고 황색도(b)는 뿌리가 높은 것으로 나타났다. 유리당은 뿌리, 줄기, 열매 모두 fructose, glucose 및 sucrose의 순으로 높게 나타났다. Acanthoside-D 함량은 줄기(18.95 mg/100 g), 뿌리(8.10 mg/100 g) 및 열매(2.85 mg/100 g)의 순으로 높게 나타났다. 유리아미노산은 줄기가 955.26 mg/100 g으로 뿌리보다는 4.5배, 열매보다는 8.5배 높게 검출되었다. 향기성분 중에서는 $\alpha$-pinene, $\beta$-pinene, 3-carene 및 D-limonene 등과 같은 천연향기 성분이 동정되었다.

화장품 항균제로 사용되는 합성물질인 paraben과 천연물질인 aroma oil의 항균력을 비교하였다. Aroma oil은 pine, rosemary, lemon, eucalyptus와 paraben은 methylparaben, butylparaben을 사용하였으며 각 농도는 0.0, 0.1, 0.2, 0.4, 0.8, 1.0wt%으로 하였다. 대상 균주는 그람양성균인 Staphylococcus aureus (ATCC No. 6538), Bacillus subtilis(ATCC No. 6633)와 그람음성균인 Escherichia coli (ATCC No. 8739), Pseudomonas aeruginosa(ATCC No. 9027)을 사용하였으며, 항균력은 disk paper method와 broth dilution method로 측정하였다. Aroma oil과 praben의 항균력은 그람음성균보다 그람양성균에 대하여 우수하게 나타났으며, aroma oil이 paraben보다 높은 항균효과를 보였다. Aroma oil은 eucalyptus, lemon, pine, rosemary 순으로 항균력이 높게 나타났으며, butylparaben이 methylparaben보다 우수하게 나타났다. Rosemary와 pine을 각각 단독으로 사용했을때 보다 3/1의 비율로 혼합하였을 때 항균력이 더욱 우수하게 증가하는 상승효과를 나타내었다.
