식물체내(植物體內) ABA의 미량분석법(微量分析法) 개발(開發)을 위(爲)하여 시험(試驗)한 결과(結果) 식물체(植物體)의 ABA 추출물(抽出物)을 pentafluorobenzyl bromide로 ester 화(化)시켜 ABA-PFB ester 형태(形態)로 GLC-ECD 분석(分析)하므로서 ABA-methyl ester 보다 높은 감도(感度)를 보여 5 pg의 ABA 까지 측정(測定)이 가능(可能)하였다.
A new method for micro-quantification of abscisic acid from plant tissue is described. GLC-ECD method of abscisic acid pertafluorobenzyl ester synthesized by reaction of plant extract with pentafluorobenzyl bromide showed higher sensitivity than that of abscisic acid methyl ester, and the detection limit of abscisic acid by the described method was as low as 5 pg.
