순비기나무의 잎, 꽃, 줄기 및 열매로부터 수증기 증류법으로 정유를 분리한 다음 GC-MS 및 GC를 이용한 표준품과 머무름 시간의 비교에 의해 76종의 성분을 동정하였다. 동정된 성분은 monoterpene hydrocarbons 16종, oxygenated monoterpenes 30종, sesquiterpene hydrocarbons 10종, oxygenated sesquiterpenes 8종, diterpenes 3종, 기타 성분 9종으로서, 특히 ${\alpha}-pinene$, ${\beta}-pinene$, sabinene, 1,8-cineole, terpinen-4-ol, ${\alpha}-terpineol$등의 monoterpene류가 주요 구성성분들이었다. 부위별 주요 구성성분으로서 잎에서는 ${\alpha}-pinene$ (30.25%) > 1,8-cineole (19.89%) > sabinene (9.56%) > ${\alpha}-ternineol$ (7.94%) > ${\beta}-pinene$ (5.69%) > terpinen-4-ol (2.37%), 꽃에서는 ${\alpha}-pinene$ (25.47%) > 1,8-cineole (7.69%) > manoyl oxide(6.21%) > ${\beta}-pinene$ (4.20%) > ${\alpha}-terpineol$ (3.76%) >sabinene (2.78%), 줄기에서는 ${\alpha}-pinene$ (13.24%)>${\alpha}-terpineol$ (10.64%)>1,8-cineole (4.40%)>manoyl oxide (4.02%) > ${\beta}-pinene$ (2.39%) > terninen-4-ol (2.21%), 그리고 열매에서는 ${\alpha}-pinene$ (20.24%) > 1,8-cineole (11.47%) > ${\beta}-pinene$ (9.79%) > u-terpineol (7.08%) > sabinene (3.68%) limonene (2.77%)의 순서로 조성비율이 높았다. 전반적으로 순비기나무의 잎과 열매에서 분리한 정유에서는 monoterpene류의 조성비율이 높았으나 꽃과 줄기에서는 잎이나 열매에 비해 sesquitepene류, diterpene류 이외에도 구조를 동정하지 못하였으나 diterpene류 일 것으로 예상되는 분자량이 비교적 큰 성분들의 조성비율이 높았다.
The essential oils isolated from leaves, flowers, stems, and fruits of Vitex rotundifolia by steam distillation and extraction (SDE) method were analyzed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). A total of 76 components detected by GC, 42 components were identified positively by GC-MS and GC co-injection with authentic standards, and 34 components were identified tentatively by mass spectral data only. They included 16 monoterpene hydrocarbons, 30 oxygenated hydrocarbons, 10 sesquiterpene hydrocarbons, 8 oxygenated sesquiterpenes, 3 diterpenes, and 9 miscellaneous components. The major components in the oil from the leaves were ${\alpha}-pinene$ (30.25%), 1,8-cineole (19.89%), sabinene (9.56%), ${\alpha}-terpineol$ (7.94%), ${\beta}-pinene$ (5.69%), and terpinen-4-ol (2.37%), and those in the flower oil were ${\alpha}-pinene$ (25.47%), 1,8-cineole (7.69%), manoyl oxide (6.21%), ${\beta}-pinene$ (4.20%), ${\alpha}-te.pineol$ (3.76%), and sabinene (2.78%). The major components in the oil from the stems were ${\alpha}-pinene$ (13.24%), ${\alpha}-terpineol$ (10.64%), 1,8-cineole (4.40%), manoyl oxide (4.02%), ${\beta}-pinene$ (2.39%), and terpinen-4-ol (2.21%) while those in the oil from the fruits were ${\alpha}-pinene$ (20.24%), 1,8-cineole (11.47%), ${\beta}P-pinene$ (9.79%), ${\alpha}-terpineol$ (7.08%), sabinene (3.68%), and limonene (2.77%). The percentage composition of monoterpenes in the oils from the leaves and the fruits were higher than in those from the flowers and the stems, whereas the oil from the flowers and the stems were characterized by a large content of sesquiterpenes, diterpenes and other unknown high molecular weight components.
