摘　　要：竹红菌甲素（HypocrellinA，HA）是我国特有的一种茈醌类色素，具有光敏性，目前发现其具有抗菌、消炎、抗病毒、抗肿瘤等生理功能。近年来HA作为一种应用前景广阔的光疗药物，在医学上已引起国内外极大关注并被成功开发。本实验测定了HA对18种主要植物病原菌的抑制作用，为HA开发绿色高效生物农药提供理论依据。Inhibition of Hypocrellin A （HA） against 18 pathogenic fungi by mycelium growth rate in light and dark conditions was evaluated. The results showed that 50 mg .L-1 HA exhibited antifungal activities against all of 18 pathogenic fungi under luminous intensity of 12 000 Lx. The inhibition rates of HA to Lecanosticta acicola, Fusarium graminearum, Valsa mali and Botryosphaeria dothidea were all higher than 90%. The EC50 of HA to Botryosphaeria dothidea and Lecanosticta acicola was 0.60 mg . L-1 and 0.77 mg . L-1 respectively. However, HA showed weak and even no antifungal activity in dark condition. The study suggested that the potential of HA could be as a new kind of photoactivated biopesticide.
