Constituents from a water-soluble portion of ethanolicextract of Iodes cirrhosa

Objective: To investigate chemical constituents of Iodes cirrhosa.Method: Constituents were isolated by using a combination of various chromatographic techniques including column chromatography over silica gel,Sephadex LH-20,and C-18,as well as reversed-phase HPLC.Structures of the isolates were identified by spectroscopic and chemical methods.Result: Twenty-four compounds were obtained from a H2O-soluble portion of an ethanolic extract of the root of Iodes cirrhosa Turcz.Structures of the isolates were ide...
