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.
