Aryltetralin lignans from Linum pamphylicum (Boiss.) Pod. sub sp. olympicum

Lignans are phenolic compounds that are very wide-spread in the plant kingdom. Lignans have been found in a large number of species belonging to more than sixty families of vascular plants and have been isolated from different parts of plants; roots and rhizomes, stems, leaves, fruits, seeds and resins [2–4] and show a wide variety of biological activities: antitumour, anti-HIV, immunosuppressive, hipolipidemic, antifungal, phytoestrogenic and antiasthmatic activities [1–3]. From a medical point of view, the most important compounds today are etoposide, teniposide and etopos, semisynthetic derivatives of podophyllotoxin which are used in cancer chemotherapy. Generally, aryltetralin types of lignans have been reported in the section Syllinum [5–8]. In Turkey, genus Linum is represented by 39 species. L. pamphyllicum is member of section Syllinum in a part of our ongoing study on the Linum species we identified podophyllotoxin and 6- methoxypodophyllotoxin from this species.
