Use of naringine, naringenine or their derivatives in the manufacture of an anticancer composition

摘要

Naringin and naringenin are disclosed as pharmaceuticals that selectively inhibit the growth of cancer cells in the presence of normal cells. They are also effective against cancer cells that are resistant to chemotherapy or radiotherapy. It is shown that naringin and naringenin selectively contract DNA chains of tumor cells but not DNA chains of normal cells. The subject compounds also exhibit anti-viral activity. A novel method for the recovery of naringin and naringenin from natural vegetable sources is taught.
