Abstract: The invention relates to active principles having an antineoplastic action, extracted from plants of the family Pittosporacee, and to pharmaceutical preparations based on at least one of the substances or compositions to be found in said extracts. With respect to other known antitumoral drugs, these antineoplastic chemotherapeutic drugs show greater selectivity towards degenerated cells and a lower level of interference with the metabolism of healthy cells. The invention also extends to the process for extraction and separation of the components of the extracts and to their use for the preparation of antineoplastic drugs or drugs for the treatment of other pathologies.

Abstract: Provided are active principles having an antitumoral activity, extracted from plants of the family Palma, the subfamily Phoenicoideae and the genus Phoenix, and pharmaceutical preparations containing at least one of the substances and compositions present in said extracts. In comparison with all the other antitumoral drugs known to date, these active principles show increased selectivity on neoplastic cells and a lower involvement of the normal cells. Also provided is a process for extraction and separation of the components of the extracts, and their use for the preparation of antineoplastic drugs and drugs for the treatment of other pathologies.
