姜黄属植物过氧化物酶同工酶的研究
刘念; 吴德邻;
中国科学院华南植物研究所
摘要:
用聚丙烯酰胺凝胶电泳分析姜黄属14种(28个样品)植物的过氧化物酶同工酶。结果表明属内种间有明显的酶谱差异,各种都有特征酶谱。根据酶谱特征及酶谱距离,结合根茎颜色,可把14个种分成三群:第一群,根茎黄色至深红色,有姜黄、毛姜黄、郁金、印尼莪术、C.petiolata和C.sP.(2);第二群,根茎灰白色,有广西莪术、大莪术和温郁金;第三群,根茎浅黄而间淡蓝色或深蓝色,有莪术、顶花莪术、细莪术、C.aeruginosa及C.zedoaria。研究结果还表明:1.国产莪术的酶谱与从美国引入的C.zedoaria和C.aeruginosa均不相同,而与引自新加坡的C.Phaeocaulis一致;2.不同形态的广西莪术具有完全一致的酶谱;3.温郁金与郁金的酶谱有差异。
