目的探讨白花蛇舌草乙醇提取物对BALB/c小鼠CT-26结肠癌细胞株增殖的抑制作用.方法采用甲基噻唑蓝(MTT)法测定不同浓度白花蛇舌草乙醇提取物对CT-26细胞株的生长抑制作用,计算半数抑制浓度(IC50).结果在同一浓度下,白花蛇舌草乙醇提取物对CT-26细胞的抑制作用随着作用时间的延长而增强,0.08 mg/mL的白花蛇舌草乙醇提取物作用CT-26细胞24 h、48 h、72 h,细胞抑制率分别为(16.67±9.35)%,(34.66±9.23)%,(40.07±9.16)%.白花蛇舌草乙醇提取物作用24 h、48 h、72 h的IC50值分别为0.315,0.155,0.115.在同一作用时间内,白花蛇舌草乙醇提取物对CT-26细胞的抑制率随着药物浓度的增加而增加,在72 h内不同浓度药物(0.06 mg/mL,0.08 mg/mL,0.10 mg/mL,0.12 mg/mL,0.14 mg/mL,0.16 mg/mL,0.18 mg/mL,0.20 mg/mL)作用下,细胞抑制率分别为(35.46±3.59)%,(40.07±9.16)%,(40.77±6.92)%,(52.81±1.87)%,(54.22±2.35)%,(68.72±3.71)%,(70.04±8.03)%,(71.84±3.12)%.结论白花蛇舌草乙醇提取物可以抑制BALB/c小鼠CT-26结肠癌细胞株的增殖,其对CT-26细胞增殖的抑制作用呈现时效和量效的关系.
Objective To explore the inhibitory effect of the ethanol extract of Oldenlandia diffusa on the proliferation of CT-26 colon cancer cells which come from BALB/c mice. Method We determined the inhibitory effect of different concentrations of ethanol extract of Oldenlandia diffusa on CT-26 cells' proliferation by using methyl thiazolyl tetrazolium (MTT), and calculated the 50% inhibiting concentration (IC50) . Results As to the same concentration, the inhibitory effect of the ethanol extract of Oldenlandia diffusa on CT-26 cells was increased with time, for exsample:after treated with 0.08 mg/mL of ethanol extract of Oldenlandia diffusa for 24 h, 48 h and 72 h, the inhibitory rates of CT-26 cells were (16.67 ±9.35)%, (34.66 ±9.23)%and (40.07 ±9.16)%, respectively. After treating CT-26 cancer cells for 24 h, 48 h and 72 h, the IC50 values of the ethanol extract of Oldenlandia diffusa were 0.315,0.155 and 0.115 mg/mL, respectively. In the same treatment time, the inhibitory effect of the ethanol extract of Oldenlandia diffusa on CT-26 cells was increased with the increase of concentration:after treatment for 72 h with different concentrations (0.06 mg/mL,0.08 mg/mL,0.10 mg/mL,0.12 mg/mL, 0.14 mg/mL,0.16 mg/mL,0.18 mg/mL and 0.20 mg/mL) of the ethanol extract of Oldenlandia diffusa,the inhibitory rates of CT-26 cells were (35.46 ±3.59)%, (40.07 ±9.16)%, (40.77 ±6.92)%, (52.81 ±1.87)%, (54.22±2.35)%, (68.72±3.71)%, (70.04±8.03)%and (71.84±3.12)%, respectively. Conclusion The ethanol extract of olenlandia diffusa can inhibit the proliferation of CT-26 colon cancer cells from BALB/c mice in a time and dose dependent manner.
