Abstract

The essential oil was obtained from the aerial part of Rhododendon mucronulatum Turcz. var. ciliatum Nakai by steam distillation, samples were collected by headspace (HS) and solid-phase microextraction (SPME) methods, and the compositions of the oil were analyzed by gas chromatography-mass spectrometry (GC-MS). Nineteen constituents were identified from the essential oil: 15 carbohydrates, 3 alcohols, and 1 acetates. Major constituents were 2-${\beta}$-pinene (16.1%), camphene (11.9%), ${\delta}$-3-carene (11.4%), d,l-limonene (9.5%), and ${\gamma}$-terpinene (9.5%). By SPME extraction, seventeen constituents were identified: 13 hydrocarbons, 1 alcohol, 1 nitrogen-containing compound, 1 acetate, and 1 amine. Major constituents of the SPME-extracted sample were cam phene (19.6%), 2-${\beta}$-pinene (18.0%), ${\delta}$-3-carene (17.4%), trimethyl hydrazine (9.7%), ${\gamma}$-terpinene (8.5%), and d,l-limonene (5.5%). By HS extraction, thirteen constituents were identified: 11 hydrocarbons, 1 alcohol, and 1 nitrogen-containing compound. Major constituents of the HS-extracted sample were camphene (25.8%), ${\delta}$-3-carene (24.8%), 2-${\beta}$-pinene (20.2%), d,l-limonene (5.4%), tricyclene (5.1%) and trimethyl hydrazine (4.6%). The fragrance of the essential oil was coniferous, balsamic, and woody, and the $IC_{50}$ value of the essential oil was 0.030 ${\mu}g/mg$ in MTT assay using UaCaT keratinocyte cell line.

우리나라의 자생식물인 털진달래(Rhododendon mucronulatum Turcz. var. ciliatum Nakai)지상부위로부터 정유를 얻고, 휘발성분을 headspace(HS)와 solid-phase microextraction(SPME)법으로 흡착시킨 다음 GC-MS로 분석하였다. 털진달래 정유에는 탄화수소 15종, 알코올 3종, 아세테이트 1종 등 총 19종의 화학성분이 함유되어 있었으며, 다함량 성분은 2-${\beta}$-pinene(16.1%), camphene(11.9%), ${\delta}$-3-carene(11.4%), d,l-limonene(9.5%), and ${\gamma}$-terpinene(9.5%)이었다. SPME법으로 흡착된 시료에는 탄화수소 13종, 알코올 1종, 질소화합물 1종 등 총 17종의 휘발성 화학물질이 함유되어 있었고, 이들 중 다함량 성분은 camphene(19.6%), 2-${\beta}$-pinene(18.0%), ${\delta}$-3-carene(17.4%), timethyl hydrazine(9.7%), ${\gamma}$-terpinene(8.5%), and d,l-limonene(5.5%)이었다. 그리고 HS법으로 흡착된 시료에는 탄화수소 11종, 알코올 1종, 질소화합물 1종 등 총 13종의 휘발성 화학물질이 함유되어 있었으며, 이들 중 다함량 성분은 camphene(25.8%), ${\delta}$-3-carene(24.8%), 2-${\beta}$-pinene(20.2%), d,l-limonene(5.4%), tricyclene(5.1%), trimethyl hydrazine(4.6%)이었다. 털진달래 정유의 향취는 coniferous, balsamic, woody하였으며, HaCaT 각질형성세포에 대한 $IC_{50}$ 값은 0.030 ${\mu}g/mg$이었다.
