  • Volatile flavor compounds were isolated from the flowers of Chrysanthemum indicum L. (gamguk) produced in Korea and China by the hydro distillation, and were analyzed by gas chromatography-mass spectrometry (GC/MS). The yield of oils from Korean and Chinese gamguk were 2.0 and 0.5%(v/w), respectively. Sixty-three volatile compounds of Korean gamguk representing 89.28% of the total peak area were tentatively identified, including 35 hydrocarbons, 12 alcohols, 6 ketones, 3 esters, 5 aldehydes, 1 oxide, and 1 miscellaneous component. Thirty-six volatile components of Chinese gamguk constituted 58.15% of the total volatile composition were tentatively characterized, consisting of 19 hydrocarbons, 7 alcohols, 2 ketones, 2 esters, 4 aldehydes, 1 oxide, and 1 miscellaneous component. The predominant components of Korean oil were ${\alpha}$-pinene, 1,8-cineol, and chrysanthenone. Whereas, camphor, ${\alpha}$-curcumene, and ${\beta}$-sesquiphellandrene were the main aroma compounds of Chinese gamguk.

  • 감국(Chrysanthemum indicum L.)은 한방재료로서 식품 및 향기제품의 소재로 활용된다. 본 연구에서는 국내에서 육성된 감국 품종별 휘발성 향기성분을 분석 및 동정하여 이들이 함유하는 화학성분을 구명하고자 수행되었다. 국내에서 육성한 네 품종(품종명 : 감국 1호, 감국 2호, 감국 3호, 원향) 감국을 동일한 시기에 같은 지역(경상남도 산청군)에서 재배하여 수확한 후 GC-MS Headspace를 이용하여 향기성분을 분석하였다. 향기성분 분석 결과 네 품종에서 23종의 성분이 동정되었고, 이 중 8개의 화합물이 공통적으로 존재하였다. 감국 1호, 감국 2호, 감국 3호에서는 3-carene, camphene, ${\beta}$-phellandrene, eucalyptol과 (+)-camphor로 등이 주요 향기성분으로 확인되었다. 감국 1호는 (+)-camphor (31.40%)를 포함하여 11개 화합물이 존재하였고, 감국 2호의 주요 향기성분으로는 camphene (25.60%)을 포함한 12개 화합물이 존재하였으며, 감국 3호는 (+)-camphor (26.88%) 등 13개 향기성분이 검출되었다. 원향에서는 주요 향기성분인 trans-piperitol (47.33%), sabinene, ${\gamma}$-terpinyl acetate을 포함한 17종류의 향기성분이 분석 되었다. 본 연구를 통해 감국 품종 간에 기능성 향기성분의 종류 및 비율의 차이가 있음을 확인하였고, 이러한 연구결과는 향후 다양한 향기제품의 산업화 소재로서 이용가치를 높일 수 있을 것으로 기대된다.

  • Determining the elution of water-soluble substances from herbal teas is an important factor in their efficient use in terms of taste, perfume, and content of health-related components. The antioxidant activity and content of catechins in commercial Chrysanthemum indicum (gamguk) teas were determined for optimum elution conditions. The water extract of gamguk teas did not differ significantly in yield compared to methanol extracts and showed stronger antioxidant activity. Catechin contents in gamguk teas were 8-18% of the extracts when individual peaks in high-performance liquid chromatography analysis were compared to standard catechin peaks. Gamguk teas exhibited faster release of antioxidants, and the antioxidant activity was positively correlated with the thermal treatments. Gukhwacha (GC) was the best tea for rapid release (30 sec) of antioxidants with the $50^{\circ}C$ treatment, whereas antioxidants in other teas were relatively slower released.
