用凝胶过滤法从玉米、黑麦、小麦和薏苡幼苗中分离出1，4-苯并恶嗪衍生物的糖苷。2-（2，4-二羟基-7-甲氧基-1，4（2H）-苯并恶嗪-3（4H）-酮）-β-β-d-吡喃葡萄糖苷（DIMBOA-Glc.）和2-（2-羟基-7-甲氧基-1，4（2H）-苯并恶嗪-3（4H）-酮）-β-d-吡喃葡萄糖苷（HMBOA-Glc.）2-（2，4-二羟基-1，4（2H）-苯并恶嗪-3（4H）-酮）-β-D-吡喃葡萄糖苷（DIBOA-Glc.）2-（2-羟基-1，4（2H）-苯并恶嗪-3（4H）-酮）-β-D-吡喃葡萄糖苷（HBOA-Glc.）黑麦和玉米。HBOA-Glc的结构。先前没有描述过。未受伤的植物组织中没有发现游离的苷元。丁博阿-葡萄糖和HMBOA-Glc。; DIBOA-Glc.和HBOA-Glc。似乎是氧化还原对，并且发现它们的相互关系随着组织的生理条件而变化。
Glucosides of 1,4-benzoxazine derivatives have been isolated from corn, rye, wheat and Coix Lachryma Jobi seedlings by gel filtration. 2-(2,4-Dihydroxy-7-methoxy-1,4(2H)-benzoxazin-3(4H)-on)-β-β-d-glucopyranoside (DIMBOA-Glc.) and 2-(2-hydroxy-7-methoxy-1,4(2H)-benzoxazin-3(4H)-on)-β-d-glucopyranoside (HMBOA-Glc.) were demonstrated in all four plants, with 2-(2,4-dihydroxy-1,4(2H)-benzoxazin-3(4H)-on)-β-d-glucopyranoside (DIBOA-Glc.) in rye, wheat and corn and 2-(2-hydroxy-1,4(2H)-benzoxazin-3(4H)-on)-β-d-glucopyranoside (HBOA-Glc.) in rye and corn. The structure of HBOA-Glc. has not been described previously. No free aglucones were found in uninjured plant tissue. DIMBOA-Glc. and HMBOA-Glc.; DIBOA-Glc. and HBOA-Glc. appear to be redox pairs and their mutual relation was found to vary with physiological conditions of the tissue.
