Antioxidant and anticholinesterase active constituents from Micromeria cilicica by radical-scavenging activity-guided fractionation
(Elsevier Sci Ltd, 2011)
From the acetone extract of Micromeria cilicica, two new (1 and 2) and five known (3-7) compounds were obtained through radical-scavenging activity guided isolation. Structures of the compounds were identified as piperitone ...
Antioxidant and Anticholinesterase Activity Evaluation of ent-Kaurane Diterpenoids from Sideritis arguta
(Amer Chemical Soc, 2009)
The petroleum ether and acetone extracts of the aerial parts of Sideritis arguta afforded two new and six known diterpenoids with the ent-kaurane skeleton. The structures of the new diterpenoids were determined as ent-7 ...
Chemical composition of the essential oil and hexane extract of Salvia chionantha and their antioxidant and anticholinesterase activities
(Pergamon-Elsevier Science Ltd, 2010)
The essential oil and methyl ester of hexane extract of Salvia chionantha Boiss. were analysed by GC and GC-MS. Totally, 54 components were detected in the essential oil and all of them were fully determined. Germacrene D ...
