Results:①The amount of human colon carcinoma cell line SW480 treated by quercetin decreased. The morphology of partial SW480 cells was shrunk volume, integrated cell membrane, condensed cytoplasm, pyknotic chromatin, nuclear fragmentation. Apoptotic Corpuscles were found by electron microscope.②MTT colorimetric assay showed quercetin inhibited the growth of human colon carcinoma cell line SW480 in a time- and dose-dependent manner when the concentration of quercetin was 30、60、90μmol/L.③Flow cytometry analysis showed the cell cycle of SW480 cell was restricted in G1/S. G0/G1 phase rate increased and S phase rate decreased with increasing concentration of quercetin and time lasting.④ Zymogram analysis assay showed the secretion of matrix metalloproteinases in human colon carcinoma cell line SW480 treated by quercetin decreased. With increasing concentration of quercetin, the secretion of MMP-2 and MMP-9 decreased.⑤Immunohistochemistry method demonstrated the position expression of Cathepsin-D in SW480 cell was suppressed by quercetin in a time- and dose-dependent manner.

研究结果：经槲皮素处理的人结肠癌SW480细胞数量减少，部分细胞体积缩小，细胞膜完整，胞浆浓缩，核染色质固缩，细胞核碎裂，形成凋亡小体；MTT法检测显示当作用浓度为30μmol/L~90μmol/L时，槲皮素对人结肠癌SW480细胞的生长有抑制作用，其抑制作用随着作用浓度的增加和作用时间的延长而增强；流式细胞学发现槲皮素主要作用于人结肠癌SW480细胞周期的G1/S期，大部分细胞被阻断于S期，随药物浓度的升高和作用时间的延长，G0/G1期细胞比例逐渐增加，S期细胞比例逐渐减少；酶谱分析法检测显示不同浓度的槲皮素能够抑制人结肠癌SW480细胞分泌MMP-2及MMP-9，随浓度的升高，MMP-2及MMP-9的分泌量减少；免疫组织化学法显示不同浓度的槲皮素处理人结肠癌SW480细胞后，Cathepsin-D的表达随药物浓度的升高和作用时间的延长而降低。
