Flavonoids of Smyrnium olusatrum from Algeria
- 79 Downloads
The genus Smyrnium is not well documented. Previous reports have shown sesquiterpene lactones to be the main constituents in the studied species [1, 2, 3, 4, 5]. The species Smyrnium olusatrum L., the subject of the present work, is traditionally also used as antiscorbutic . To our best knowledge, flavonoids have never been reported from the genus.
Smyrnium olusatrum L. (Apiaceae) was collected in May 2006 at Constantine (eastern Algeria). The plant was gathered by Mr. Kamel Kabouche and authenticated by Prof. Gerard De Belair (Annaba University, Algeria). A voucher specimen (ZKLOST So05/06) was deposited at the Herbarium of the Laboratory of Therapeutic Substances (LOST), Faculty of Sciences, Mentouri-University, Constantine, Algeria.
Air-dried and powdered aerial parts (1 kg) of Smyrnium olusatrum L.  were macerated in a methanolic solution (70%). The extract was successively concentrated to dryness (under low pressure); the residue was dissolved in boiling water and extracted...
