Abstract

In order to extract the essential oil contained in the Elsholtzia splendense Nakai, a fully-bloomed individual was collected and the living body was used for the experiment. Plants were divided into 0.7kg of flowers and 1.5kg of leaves + stems, and extracted by parts and used for scent pattern analysis, and extracted after adding 5kg of outpost for the analysis of essential oil components. Essential oil extraction was performed using the SDE method improved by Schultz et al. (1977), and the extraction time was limited to 1 hour after the material started boiling. The extracted essential oil component was analyzed for fragrance pattern analysis using an e-nose, and the results of analyzing the substance of the essential oil component by GC-MS are as follows. 1. As for the fragrance pattern analysis, in the case of essential oils extracted from flowers, the scent quality was the best at 10-20 minutes, and the scents extracted from stems and leaves were somewhat of poor scent quality, but the fragrance was good at 10-40 minutes. The intensity of scent was the strongest in 10-20 minutes, and the intensity of incense was high even in 30-40 minutes. The scent extracted from the stems and leaves was generally not strong, but appeared high in 10 to 20 minutes. 2. There were 40 kinds of essential oils contained in Elsholtzia splendense Nakai oil. Among them, Mequinol, Benzene, 1,2,3,4-tetramethyl, Elsholtziaketone, and Dehydroelsholtziaketone were identified.

꽃향유에 함유된 정유를 추출하기 위해 개화한 개체를 채집한 후 생체를 실험에 이용하였다. 재료는 꽃 0.7kg, 잎 + 줄기 1.5kg으로 나누어 부위별로 추출 후 향기패턴 분석에 사용하였고, 정유성분 분석을 위해 전초 5kg을 넣은 후 추출하였다. 정유추출은 Schultz등(1977)이 개량한 SDE 법으로 정유를 추출하였으며, 추출시간은 시료가 끓기 시작한 후부터 1시간으로 하였다. 이렇게 추출한 정유성분을 전자코를 이용하여 향기패턴 분석과 GC-MS로 정유성분의 물질을 분석하였던 결과는 다음과 같다. 1. 향기패턴 분석은 꽃에서 추출한 정유성분의 경우 10~20분에 나오는 향의 질이 가장 좋았고 줄기와 잎에서 추출한 향은 다소 향의 질은 좋지 못했지만 10~40분에 나오는 향이 좋았다. 향의 세기는 꽃만으로 추출한 것은 10~20분에서 가장 강한 향이 나왔고, 30~40분에서도 향의 세기는 높게 나타났다. 줄기와 잎에서 추출한 향은 대체로 향의 세기가 강하지 못하였지만 10~20분에서 높게 나타났다. 2. 꽃향유에 함유된 정유의 종류는 40종을 얻었다. 이중 Mequinol, Benzene, 1,2,3,4-tetramethyl, Elsholtziaketone, Dehydroelsholtziaketone을 확인하였다.
