Evaluation of Antioxidant Properties of Phaulopsis fascisepala C.B.Cl. (Acanthaceae)
The antioxidant activities of crude extract of Phaulopsis fascisepala leaf were evaluated and compared with alpha-tocopherol and BHT as synthetic antioxidants and ascorbic acid as natural-based antioxidant. In vitro, we studied its antioxidative activities, radical-scavenging effects, Fe(2+)-chelating ability and reducing power. The total phenolic content was determined and expressed in gallic ...
متن کاملTerpenoids from Achillea setacea.
The aerial parts of Achillea setacea afforded, in addition of a rare monoterpene triol and 12 known sesquiterpene lactones, a new guaianolide containing an endoperoxide ring. Its structure was elucidated by spectral methods.
متن کاملTerpenoids from endophytic fungi.
This work reviews the production of terpenoids by endophytic fungi and their biological activities, in period of 2006 to 2010. Sixty five sesquiterpenes, 45 diterpenes, five meroterpenes and 12 other terpenes, amounting to 127 terpenoids were isolated from endophytic fungi.
متن کامل[Terpenoids from Euphorbia antiquorum L.].
To study the chemical constituents of Euphorbia antiquorum L., the constituents were isolated with normal-phase and reverse-phase silica gel column chromatography and their structures were elucidated on the basis of spectroscopic data. Seven terpenoids were obtained from EtOAc extract of E. antiquoru L. They were identified as antiquorine A (1), antiquorine B (2), ent-13S-hydroxy-16-atisene-3,1...
متن کاملTerpenoids from the Octocoral Sinularia gaweli
Two eudesmane sesquiterpenoids, verticillatol (1) and 5α-acetoxy-4(14)-eudesmene-1β-ol (2) and two cembrane diterpenoids, (-)-leptodiol acetate (3) and sinulacembranolide A (4) were isolated from the octocoral Sinularia gaweli and compounds 2-4 are new isolates. The structures of new terpenoids 2-4 were elucidated by spectroscopic methods and by comparison the spectral data with those of known ...
