This study investigated the chemical composition of Solidago virga-aurea var. asiatica Nakai essential oils collected using different extraction methods. The essential oils obtained by simultaneous steam distillation extraction (SDE) and hydrodistillation extraction (HDE) methods from the aerial parts of Solidago virga-aurea var. asiatica Nakai were analyzed by GC and GC-MS. Ninety-nine volatile flavor compounds were identified in the essential oil produced from Solidago virga-aurea var. asiatica Nakai using the SDE method. These compounds were classified into eight categories in terms of chemical functionality: 26 hydrocarbons, 8 aldehydes, 36 alcohols, 7 ketones, 12 esters, 5 oxides and epixides, 4 acids, and a miscellaneous one. Spathulenol (15.66%) was the most abundant compound. Ninety-eight compounds including of 35 hydrocarbons, 6 aldehydes, 29 alcohols, 6 ketones, 10 esters, 4 oxides and epixides, 7 acids, and a miscellaneous one were identified in the essential oil from the plant using the HDE method. Hexadecanoic acid (24.74%) was the most abundant compound. The chemical composition of Solidago virga-aurea var. asiatica Nakai essential oils extracted by SDE and HDE methods are characterized by high content of sesquiterpene alcohols and acids, respectively. The extraction methods may be influenced in the chemical composition of natural plant essential oils.

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.

본 연구에서는 울릉도 특산 약용 작물 추출물이 항염증에 대한 실험연구가 이루어져 있지 않은 것에 착안하여 LPS에 의해 활성화된 대식세포로부터 유도되는 염증반응에 대한 억제효과를 조사하였다. 울릉도 자생 식물인 곰취, 미역취, 삼나물의 세가지 식물 추출물을 이용하여 피부 염증에 대하여 연구를 하였다. 산화질소와 cytokine의 생산은 면역세포의 대표적인 염증인자이다. 세포는 LPS 처리 후 한 시간 뒤에 곰취, 미역취, 삼나물 70% 아세톤 추출물을 처리를 하였다. 세포 독성이 나타나지 않는 농도인 1, 10, 100 ug/ml를 사용하였다. 곰취, 미역취, 삼나물 70% 아세톤 추출물은 NO, $PGE_2$, TNF-${\alpha}$, IL-1${\beta}$, IL-6, iNOS, COX-2의 생성을 저해 시켰다. $PGE_2$는 100 ug/ml의 농도에서 60%에 가까운 저해율을 나타내었다. iNOS와 COX-2 역시 100 ug/ml의 농도에서 각각 54%, 65%가 저해가 되었다. 게다가 곰취, 미역취, 삼나물 70% 아세톤 추출물은 염증성 사이토 카인인 TNF-${\alpha}$, IL-1${\beta}$, IL-6의 생성을 감소 시켰다. 이러한 결과로 곰취, 미역취, 삼나물 추출물은 염증 예방과 치료에 효과적임을 확인할 수 있었다.

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.

Objectives : This study aimed to analyze contents of chlorogenic acid among major ingredients and determine the optimal solvent for the antioxidant activity from Solidago virga-aurea var. gigantea(SV) aerial part. Methods : Mature aerial part of extracted SV at the first crop on June 2018 was used. SV was mixed with each at the ethanol concentrate rates of water, 10, 30, 50, 70, and 100% and extracted them for three times for eight hours at $70^{\circ}C$. The contents of chlorogenic acid and seven kinds of antioxidant activities were measured in SV extracts. Results : The highest the contents of chlorogenic acid was from 10% ethanol extracts showed. Total polyphenol and flavonoids of SV extracts were 126.16 mg/g and 105.84 mg/g, respectively. Scavenging activities of DPPH, ABTS, and hydroxyl radical significantly increased in a dose-dependent in SV extracts, while it was almost similar with control at the concentration of $500{\mu}g/mL$. $Fe^{2+}$ chelating activity significantly increase in a dose-dependent in SV extract, it was lower than control. Nitrite scavenging activity increased, dose-dependent in the sequence of pH 1.2> pH 3.0 > pH 6.0 in SV extracts, while it was almost similar with control at the concentration of $500{\mu}g/mL$, pH 1.2, and pH 3.0. Conclusions : Thus, this study found that higher contents of chlorogenic acid and excellent antioxidant activity were contained in 10% ethanol extracts in mature aerial part of SV. It is expected to be used as basic data as natural antioxidant materials.
