주요 소나무류잎의 특수성분을 분석하여 시판되고 있는 솔잎 가공식품의 기초데이터를 제공함과 동시에 임산화학 분야의 학문적 기초데이터를 축적하기 위하여 실시한 결과, 펙틴은 잣나무가 가장 높게 분석되었으며, 탄닌은 잣나무가 높게 분석되었고, 소나무와 해송은 유사하였다. 테르페노이드 성분중 ${\alpha}$-pinene은 소나무와 잣나무에서, ${\beta}$-pinene은 리기다와 해송에서 높게 분석되었으며, 희귀성분으로는 잣나무에서 sabinene과 citronellol, 리기다에서는 ${\alpha}$-pinene oxide 등이 분석되었다. 특히 소나무잎에 다량 존재하는 성분은 ${\alpha}$-pinene, ${\beta}$-caryophyllene, ${\beta}$-phellandrene, ${\Delta}^3$-carene, phytol 등 이었다. 향기성분의 주체인 ${\alpha}$-pinene, limonene, bornylacetate들이 소나무와 잣나무에서 보다 많이 분석된 것으로 보아 삼림욕의 신선하고 상쾌한 내음의 주체성분이라고 생각된다.

블루베리혹파리(Dasineura oxycoccana)(파리목: 혹파리과)는 국내에서 재배되고 있는 블루베리의 주요해충으로 알려져 있다. 우리는 이 해충을 효과적으로 예찰하기 위한 수단을 개발하고자, 블루베리 휘발성 물질과 성페로몬의 유인 효과를 검정하였다. 블루베리로부터 방출되는 휘발성 물질을 고체상미량추출법(SPME)으로 포집하여 기체크로마토그래피-질량분석기(GC-MS)로 분석한 결과, 꽃의 주요 물질은 cinnamaldehyde와 cinnamyl alcohol이었고, 신초와 어린과실의 주요 물질은 β-caryophyllene, germacrene D, 및 α-farnesene인 것으로 조사되었다. 2019년에 군산에 소재하고 있는 블루베리 포장에서 시판 중인 cinnamaldehyde, cinnamyl alcohol, β-caryophyllene, 및 α-farnesene의 효능을 시험하였는데, 이 4가지 성분을 단독 또는 혼합물로 처리하였을 때 블루베리혹파리는 유인되지 않았다. 반대로 이 종의 성페로몬으로 알려진 (2R,14R)-2,14-diacetoxyheptadecane은 수컷을 효과적으로 유인하였다. 유인효과에 있어서 성페로몬과 기주식물 휘발성 물질 사이에 시너지 효과는 관찰되지 않았다. 2020년 군산 블루베리 포장에서 블루베리혹파리 성충은 5월부터 8월까지 성페로몬 트랩에 유인되었고, 발생최성기는 3회로서 5월 중순, 6월 하순, 및 7월 하순으로 나타났다.

Background: Allelopathy has been suggested as one potential mechanism facilitating the successful colonisation and expansion of invasive plants. The impacts of the ongoing elevation in atmospheric carbon dioxide (CO₂) on the production of allelochemicals by invasive species are of great importance because they play a potential role in promoting biological invasion at the global scale. Common ragweed (Ambrosia artemisiifolia var. elatior), one of the most notorious invasive exotic plant species, was used to assess changes in foliar mono- and sesquiterpene production in response to CO₂ elevation (389.12 ± 2.55 vs. 802.08 ± 2.69 ppm). Results: The plant growth of common ragweed significantly increased in elevated CO₂. The major monoterpenes in the essential oil extracted from common ragweed leaves were β-myrcene, DL-limonene and 1,3,6-octatriene, and the major sesquiterpenes were β-caryophyllene and germacrene-D. The concentrations of 1,3,6-octatriene (258%) and β-caryophyllene (421%) significantly increased with CO₂ elevation. Conclusions: These findings improve our understanding of how allelochemicals in common ragweed respond to CO₂ elevation.

A comparison of essential oils composition of Aster tataricus L. (gaemichwi), Ligularia fischeri (gomchwi), Solidago virga-aurea var. asiatica Nakai (miyeokchwi), and Aster scaber (chamchwi) was performed by gas chromatography and mass spectrometry for the identification of volatile flavor characteristics in chwi-namuls. The essential oils were extracted by the hydro distillation extraction method. One hundred volatile flavor components were identified from gaemichwi essential oil. ${\alpha}$-Pinene (11.5%) was the most abundant compound, followed by myrcene (8.9%) and ${\beta}$-pinene (7.5%). Ninety-one volatile flavor components were identified from the essential oil of gomchwi. Aromadendrene (14.8%) was the most abundant component, followed by ${\beta}$-caryophyllene (7.6%) and 1-methyl-4-(1-methylethylidene)-cyclohexene (7.3%). Ninety-five volatile flavor constituents were detected in the essential oil of miyeokchwi, moreover, spathulenol (15.7%) was the most abundant component. Ninety-six volatile flavor constituents were detected in the essential oil of chamchwi. Epi-bicyclosesquiphellandrene (21.9%) was the most abundant component, followed by ${\beta}$-caryophyllene (9.5%) and ${\delta}$-terpinene (8.9%). The essential oil composition of gaemichwi was characterized by a higher contents of pinenes. The essential oil composition of gomchwi can be easily distinguished by the percentage of aromadendrene. Spathulenol and epi-bicyclosesquiphellandrene were regarded as the characteristic odorants of miyeokchwi and chamchwi, respectively.

The essential oils of leaves and resins from P. densiflora and P. koraiensis were analyzed to identify their components. After each retention times of 45 known terpenoids were dertermined with a fixed analytical condition by GC the essential oil compounds of leaves and resins were identified by comparing their retention times with the retention times of known standards. To confirm these results the essential oil components of leaves from P. koraiensis were analized by 2 different GC/MS. According to these results, 36 terpenoids in essential oils of leaves from P. densiflora and P. koraiensis were identified and 15 terpenoids and 22 terpenoids were identified from P. koraiensis resin and P. densiflora resin, respectively.

This study investigated the volatile flavor composition of essential oils from Solidago virga-aurea var. asiatica Nakai with different harvesting area. The essential oils obtained by the hydrodistillation extraction method from the aerial parts of the plants were analyzed by gas chromatography (GC) and GC-mass spectrometry (GC-MS). Ninety-five (91.61%) volatile flavor compounds were identified in the essential oils from the S. virga-aurea var. asiatica Nakai harvested in Koheung, Jeolanamdo. The major compounds were hexadecanoic acid (29.22%), 7-hexyl eicosane (9.12%), spathulenol (7.701%), 3,8-dimethyl decane (6.48%), caryophyllene oxide (4.52%) and α-copaene (4.23%). Fifty-seven (97.43%) volatile flavor compounds were identified in the essential oils from the S. virga-aurea var. asiatica Nakai harvested in Seoguipo, Jejudo. The major compounds were 2-carene (40.95%), α-copaene (10.77%), α-muurolene (5.81%), and spathulenol (3.11%). The chemical composition of the essential oils was significantly different in quality and quantity with the different harvesting area. The quantitative variations of hexadecanoic acid, 7-hexyl eicosane, spathulenol, 3,8-dimethyl decane, caryophyllene oxide, 2-carene, and α-copaene according to different harvesting area can serve as a quality index of the S. virga-aurea var. asiatica Nakai essential oils in food industries.

In this study, we identified the volatile compounds of Artemisia princeps Pampan. cv. ssajuari (ssajuarissuk) essential oils and analyzed changes in the contents of volatile compounds under four different storage conditions, such as exposure to air at $20^{\circ}C$ and $40^{\circ}C$. Sixty-five volatile compounds consisting of 6 monoterpene hydrocarbons, 23 oxygenated monoterpenes, 16 sesquiterpene hydrocarbons, 6 oxygenated sesquiterpenes, 1 diterpene, 6 benzene derivatives, and 7 non-isoprenoid compounds were identified on the basis of their mass spectra characteristics and retention indices from original ssajuarissuk essential oils. Identified compounds constituted 90.56% of the total peak area. Borneol (10.29%) was the most abundant compound in the original ssajuarissuk essential oils, followed by 1,8-cineole (9.06%), viridiflorol (8.99%), spathulenol (8.73%), $\alpha$-thujone (5.28%), and camphor (4.39%). After six months storage at $40^{\circ}C$ with the cap opened for 3 min everyday, the total amount of volatile compounds in essential oil as determined by the percentage peak area decreased by 84.93%. The total levels of cis-sabinene hydrate, camphor, 4-terpineol, humulene oxide, $\beta$-caryophyllene oxide, and caryophyllene alcohol increased significantly. For ssajuarissuk essential oils stored under experimental conditions, changes in the contents of volatile compounds in essential oils were accelerated by temperature and contact with the atmosphere.
