Phytochemical investigation of Tanacetum parthenium L. family Asteraceae cultivated in Egypt resulted in isolation and identification of four flavonoids. One surface flavonoid was isolated from the fresh leaves and three other flavonoids were isolated from the flower heads. Four sesquiterpene lactones were isolated from the leaves. Two sterols were isolated from the roots. A comparative study o...

The lipophilic ̄avonoids in leaf and ̄ower of Tanacetum parthenium and T. vulgaris have been compared. While those of T. parthenium are methyl ethers of the ̄avonols 6-hydroxykaempferol and quercetagetin, the surface ̄avonoids of T. vulgare are methyl ethers of the ̄avones scutellarein and 6-hydroxyluteolin. Apigenin and two ̄avone glucuronides are surprisingly present in glandular trichomes on...
