紅花是菊科一年生草本植物红花(Carthamus tinctorius L.)的花冠,别名草红花,在我国新疆吉木萨尔、河南新乡、四川简阳等地大量种植,资源量丰富[1]。红花为传统中藏药,主要用于治疗冠心病、心绞痛、跌打损伤、高血压及妇科疾病等[2]。现代药理学研究发现,红花具有降低冠脉阻力[3]、抑制血小板聚集[4]、改善心脑血液循环[5]、抗炎[6]及抗肿瘤[7-8]等功效,进一步研究发现其主要有效成分为红花黄色素、羟基红花黄色素、多糖类等水溶性成分[9]。但对于红花超临界萃取物的化学成分及抑菌活性的报道极少。笔者采用超临界CO2萃取了红花花冠的脂溶性成分,并对其化学成分和抗菌活性进行了初步的研究,为红花脂溶性成分的开发利用提供科学依据。
