Flavonoids from the aerial parts of Artemisia biennis Willd
Background and objectives: The genus Artemisia contains over 250 species all over the world. A. biennis Willd is one of the species which grows wildly in Iran. Camphor and (E)-beta-farnesene have been reported as the major components of the essential oil from A. biennis. In spite of the presence of a rather wide range of reported bioactivities there i...
متن کاملNew diterpenoids from the aerial parts of Salvia reuterana
The genus Salvia is a valuable origin of structurally diverse terpenoids. In a project directed at structurally interesting bioactive metabolites from Iranian Salvia species, we studied Salvia reuterana. Two new labdane diterpene, 6β,14α-dihydroxy-15-acetoxysclareol (1), and 14α,15- dihydroxy sclareol (2), were isolated from the aerial part of the plant. Their structures were established mainly...

متن کاملPolysaccharide from the Roots of Polygonum Equisetiforme Sibth. & Sm.: Isolation, Chemical Composition, Antioxidant Potential and Cytotoxic Activity
A water-soluble polysaccharide (PEP) was isolated and purified from the aqueous extract of Polygonum equisetiforme Sibth. & Sm. roots. Structural features of PEP were investigated by a combination of instrumental and chemical analyses, including acid hydrolysis, methylation analysis, IR, GPC, HPLC and GC/MS. The results indicated that PEP has a backbone of (1→4)-linked glucose residues, which o...
متن کاملIdentification and quantitative determination of flavonoids in the aerial parts of Teucrium polium by HPLC
Review of literature shows that large varieties of compounds have been found to bear hypoglycemic action. For instance, glycosides afford active principles that lower blood sugar in test animals. Following the I.V. administration of a 4 percent decoction of the dried T. polium herb, a definite reduction of blood sugar level has been exhibited. With reference to PDR for Herbal Medicines for the ...
