中文大意: 對(duì)于DHT前人做了很多研究。黃柳舒采用柱層析方法和逆流色譜方法,結(jié)合Sephadex LH-20和制備型HPLC等技術(shù)對(duì)山核桃外果皮的石油醚萃取相和乙酸乙酯萃取相分別進(jìn)行分離純化得到DHT。研究表明該化合物對(duì)人的宮頸癌Hela細(xì)胞及人的肝癌SMMC-7721細(xì)胞具有一定的體外增殖抑制作用。吳德玲等采用硅膠柱色譜和Sephadex LH-20對(duì)山核桃外果皮的化學(xué)成分進(jìn)行分離純化得到了DHT,并通過(guò)MTT法對(duì)分離出的DHT進(jìn)行了抗腫瘤活性研究,發(fā)現(xiàn)DHT具有一定的抗腫瘤活性。 謝謝! |

| Predecessors had made many investigations on DHT. In the study of Liushu Huang, DHT was separated and purified from petroleum ether and ethyl acetat extraction phase of pecan epicarp on the basis of using column chromatography method and countercurrent chromatography method combined with Sephadex LH-20 and preparative HPLC technologies. |

The results showed that this compound (DHT) had certain inhibition effect on vitro proliferation of human cervical carcinoma HeLa cell and liver cancer SMMC-7721 cell. Chemical components of pecan epicarp were separated and purified to obtain DHT based on Deling WU's study of using silica gel column chromatography and Sephadex LH-20, and the antineoplastic activity of separated DHT was investigated through MTT method, and it indicated that DHT has some antineoplastic activity. |
