Isolation and Identification of Chemical Constituents from Ethanol Extract of Camptosorus sibiricus
To study the chemical constituents in 95%ethanol extract of the whole plant of
Camptosorus sibiricus
and determine its antioxidant activity.
Method:
2
Compounds were isolated by a combination of various chromato-graphic techniques
including column chromatography over silica gel and Sephadex LH-20 and reversed-phase HPLC. Their structures were identified on the basis of physicochemical properties and spectral data reported in the literature.
Result:
2
Eleven compounds were identified as

Compounds 3-11 are isolated from the genus
Camptosorus
for the first time. In the
in vitro
SOD-like activity assays
compounds 7
