其中水蓼、川黄柏、连翘等8种植物提取物对黄瓜白粉病菌具有较好抑制作用，EC50值均小于0.5%，除茵陈和马齿苋外，其他6种植物提取物对黄瓜白粉病的保护效果均高于治疗效果。8种植物提取物在1.25%浓度下对黄瓜白粉病的保护效果均高于化学药剂三唑酮100μg/mL(74.42%)；1.25%的川黄柏、广藿香、马齿苋、蛇床子、南五味子提取物对黄瓜白粉病的治疗效果达到82%以上，高于三唑酮100μg/mL(78.89%)，说明在黄瓜白粉病发生之前或初期使用这8种植物提取物能够达到较好的防治效果。

The cytomorphological changes of K562 cells were observed in the electron microscope.Results RRTJ at the concentration of 1μL/mL expressed obviously inhibitory effect on the growth of K562 cells.The inhibitory effect at the concentration of 2μl/ml went up to its highest at 83.4%.RRTJ showed virulence to K562 cells.The karyon changed because of RRTJ attending.

结果 每mL培养液含1μL刺梨汁即对肿瘤细胞增殖有明显的抑制作用，每mL培养液含2μL刺梨汁抑制作用达到最大，为83.4%，再加大剂量抑制作用无明显升高，各种剂量的刺梨汁对细胞均无毒性，刺梨汁的加入使得细胞体积明显变小，细胞核形态发生改变，异染色质增多。
