Abstract:
Chemical constituents of water extracts of Asplenium ruprechtii were investigated. Five compounds were isolated by silica gel, Sephadex LH-20 gel column chromatographies and preparative HPLC, and their structures were identified by various spectral analyses as aspleniumside G(1), trans-p-coumaric acid(2), trans-p-coumaric acid 4-O-β-D-glucoside(3), cis-p-coumaric acid 4-O-β-D-glucoside(4), and(E)-ferulic acid-4-O-β-D-glucoside(5). Among them, compound 1 is a new 9,19-cycloartane glycoside.
