[Studies on chemical constituents in rhizome of Matteuccia struthiopteris].

To study the chemical constituents in rhizome of Matteuccia struthiopteris.The compounds were isolated by normal phase silica gel chromatography. The structures were identified by physical and spectral data.Six compounds were isolated and identified as woodwardic acid (1), ergost-6,22-diene-3beta,5alpha,8alpha-triol (2), apigenin (3), riboflavin (4), 4-O-beta-D-glucopyranosyl-p-coumaric acid (5), 4-O-beta-D-glucopyranosylcaffeic acid (6).All the compounds were obtained from this plant for the first time.
