Chemical constituents from rhizome of Matteuccia orientalis / 中草药

Objective: To study the chemical constituents from 60% ethanol extract of the rhizomes of Matteuccia orientalis. Methods: Chromatographic methods were used for the isolation and purification. Structures were identified on the basis of spectroscopic analysis. Results: Eleven compounds were isolated from M. orientalis and identified as (±)-thunberginol C (1), (2S)-5, 7, 3′, 5′-tetrahydroxyflavanone (2), naringenin (3), strobopinin (4), farrerol (5), leptorumol (6), cis-3, 5-dihydroxystilbene (7), dihydropinosylvin (8), paeonol (9), 3, 4-dihydroxybenzalacetone (10), and caffeic acid methyl ester (11). Conclusion: Compounds 1-11 are isolated from the plants of Matteuccia Todaro for the first time.
