| 摘要: |
| 该研究采用超声提取法,得到红海榄的叶、秋茄的茎和叶、水黄皮的叶和桐花树的茎的95%乙醇提取物,并用MTS法检测提取物对前列腺癌DU145、PC3细胞增殖抑制效果,结果桐花树茎95%乙醇提取物对DU145细胞增殖抑制作用最强,对DU145干预24、48、72 h的IC50分别为75.23、88.81、76.53 μg·mL-1。在此基础上,依次采用石油醚、乙酸乙酯、正丁醇对桐花树茎95%乙醇提取物进行梯度萃取,得到不同极性部位后选择桐花树茎乙酸乙酯部位(EACS)对19种肿瘤细胞(HT-29,SW480,DLD-1,COLO205,PC3,DU145,SKOV3-S,A2780,SGC-7901,Tca-8113,MDA-MB-231,HepG2,SMMC-7721,Bel-7402,MHCC-97H,Hela,PANC-1,EJ,A549)和3种正常细胞(HUVEC,EC304,RWPE-1)进行MTS实验检测其抗增殖作用,用集落形成进一步检测EACS对细胞HT-29、DLD-1、SW480、DU145、PC3、SKOV3-S的增殖影响。结果表明:EACS对16个肿瘤细胞和3个正常细胞均具有不同程度的增殖抑制作用,其中对RWPE-1的增殖抑制作用最强,药物作用72 h后的IC50为22.78 μg·mL-1; EACS对细胞HT-29、DLD-1、SW480、DU145、PC3、SKOV3-S的集落形成均具有抑制作用,抑制作用强度与浓度成正相关关系。 |

| Abstract: |
| Ninety-five percent of ethanol extracts from the leaves of Rhizophora stylosa, stems and leaves of Kandelia candel, leaves of Pongamia pinnata and stems of Aegiceras corniculatum were extracted by ultrasonic extraction method. The cytotoxicity of 95% ethanol extracts from these four mangrove plants on prostate cancer cells DU145 with 24, 48 and 72 h and PC3 were tested by MTS assay. The results showed that the anti-proliferation on prostate cancer cell DU145 of 95% ethanol extract of A. corniculatum stems was the strongest among the tested samples with IC50 value of 75.23, 88.81 and 76.53 μg·mL-1 to DU145, respectively. On this basis, the ethanol extract of A. corniculatum stems was successively treated with petroleum ether, ethyl acetate and n-butanol to yield four fractions, then the ethyl acetate fraction of A. corniculatum stems(EACS)were tested for anticancer activities against nineteen tumor cells(HT-29, SW480, DLD-1, COLO205, PC3, DU145, SKOV3-S, A2780, SGC-7901, Tca-8113, MDA-MB-231, HepG2, SMMC-7721, Bel-7402, MHCC-97H, Hela, PANC-1, EJ, A549)and antiproliferative effects of three normal cells(HUVEC, EC304, RWPE-1)by MTS assay, the effects of EACS on proliferation of HT-29, DLD-1, SW480, DU145, PC3 and SKOV3-S cells were detected by the colony formation assay. The results showed that EACS exhibited different degrees of inhibitory effect on proliferation of sixteen tumor cells and three normal cells, and had the stronger inhibitory effect on the proliferation of RWPE-1 with IC50 value of 22.78 μg·mL-1 after 72 h drug treatment. EACS inhibited the colony formations of HT-29, DLD-1, SW480, DU145, PC3 and SKOV3-S cells in a dose-dependent manner. |
