摘要
Ｍｅｄｅｒｍｙｃｉｎ、Ｇ－１５Ｆ和Ｇ－１５Ｇ三个化合物都有醌式结构。在底物甘油中，准分子离子为（Ｍ＋３Ｈ）＋，但在底物３－硝基苯甲醇（ＮＢＡ）中，准分子离子为（Ｍ＋Ｈ）＋。本文用ＦＡＢＭＳ对此作了研究。
In the present paper the quasi-moleculer ion of quinone compounds-medermycin,G-15F and G-15G was Measured.We have found that the quasi-moleculer ion in the glycerol matrix is not the same as in the 3-nitrobenzyl alcohol(NBA) matrix.They are(M+3H) +and (M+H)+ respectively.It probably resulted from the hydroquinone in the glycerol matrix of the FAB source.
