Abstract
From the leaves of Ixeris sonchifolia (Compositae), luteolin and its glucoside and apigenin glucuronide were isolated and their structures were characterized on the basis of spectral data. Besides these flavonoids, the composition and relative content of free amino, acids and related compounds, compared to standards determined under identical conditions was also investigated using automatic amino acid analyzer. Major free amino acids were glutamic acid, aspartic acid, serine, proline, valine and arginine.
고들빼기 잎으로부터 플라보노이드인 luteolin, luteolin 7-0-glucoside 및 apigenin 7-0-glucuronide를 분리하고 그들의 구조를 기기적인 분석방법에 의하여 동정하였으며 또한 유리 아미노산과 관련 화합물들의 조성과 상대함량을 표준품과 동일조건하에서 아미노산 자동분석기로 비교 검토하였다. 가장 함량이 많은 유리 아미노산들은 glutamic acid, aspartic acid, serine, proline, valine 그리고 arginine이었다.
