Since Houttuynia cordata is well known as a medicinal herb, due to its antibacterial activity on various microorganisms, present investigation was performed to identify the flavor compounds for volatile essential oil. Volatile essential oil was collected by simultaneous distillation-extraction(SDE), and then the oil components were separated on HP-5 capilliary column$(25m{\times}0.25mm\; i.d.)$ and identified those components by GC-MS. Fifty two compounds were isolated from the volatile essential oil of Houttuynia cordata and forty four were positively identified by GC-MS. The volatile compounds were composed mainly of terpenoids(25 classes), aldehydes(7 classes), alcohols(4 classes), ketones(3 classes), acids(1 class) and miscellaneous compounds(4 classes). Of these, the major compounds were ${\beta}-myrcene$, ${\beta}-ocimene$, decanal, 2-undecanone and geranyl propionate.

민간요법에서 각종 질병치료에 사용되고 있는 어성초의 항균활성 물질을 규명하기 위한 목적으로 연속증류추출장치를 이용하여 포집한 휘발성 정유를 GC-MS로 각 성분을 분리 동정했다. 그 결과 어성초의 휘발성 정유는 GC column에서 52종의 화합물로 분리되었으며, 이중 44종의 화합물이 GC-MS에서 동정되었다. 밝혀진 화합물들은 terpene류 25종, aldehyde류 7종, alcohol류 4종, ketone류 3종 및 기타 5종이며, 이들 중 주요 화합물은 ${\beta}-myrcene$, ${\beta}-ocimene$, decanal, 2-undecanone 및 geranyl propionate이었다.
