초록

SDE연속추출장치로 추출, 농축한 어성초 휘발성 향기성분 추출물이 15종의 병원성 세균에 대한 항균활성을 측정한 결과는 다음과 같았다. 어성초의 추출물은 주로 Vibrio와 Bacillus속의 세균들에 대해 강한 항균활성을 나타냈고, S. aureus와 epidermidis, S. dysenteriae, C. xerosis, L. monocytogenes에도 비교적 높은 활성을 나타냈다. 하지만 E. coli, S. typhi, E. cloaceae, Y. enterocolitica와 같은 세균들은 어성초 휘발성 향기성분 농축물에 저항성을 가지는 것으로 나타났다. 어성초의 잎과 줄기에 대한 일반성분 중 수분, 조단백질, 조지방, 조회분은 잎에 많이 함유되어 있고 조섬유는 줄기에 많이 함유되어 있었다. 잎에서 9종의 유리아미노산이 검출되었고, 줄기에서는 8종의 유리아미노산이 총 8.81 mg/l00 g 으로 더욱 많이 검출되었다. 지방산조성을 분석한 결과 잎과 줄기에 linolenic acid (C18:3), linoleic acid (C18:2), palmitic acid (C16:0)이 다량 함유되어 있다. 무기성분 중 잎과 줄기에서 K의 함량이 가장 많았고 Ca, P, Mg, Fe, Zn, Cu의 순으로 많이 함유되어 있었다.

For developing natural antibacterial agents from Houttuynia cordata Thunb., antibacterial effects of volatile flavor component using various bacterial sp. were tested. Extraction from Houttuynia cordata Thunb. by using SDE (Simultaneous steam Distillation-Extraction) showed strong antibacterial activities against Vibrio and Bacillus genus, such as Vibrio. cholerae, V. parahaemolyticus, V. vulnificus, Bacillus. cereus, and B. subtilis. Then chemical compositions of leaf and stem were analyzed. The contents of crude protein, lipid, and ash in stem were less than those of leaf, but fiber contents were higher than those of leaf. Among the amino acids, aspartic acid, glutamic acid, glycine, and arginine were higher than those of other amino acids. Linolenic acid, linoleic acid, oleic acid, and palmitic acid were major fatty acids. Major minerals of Houttuynia cordata Thunb. were potassium, calcium, phosphorus, magnesium, iron, zinc, and copper. Especially, in the case of potassium, it was highest.
