Abstract:
To investigate the chemical constituents from the aerial parts of Lygodium japonicum. Methods:Various chromatographic techniques were employed for isolation and purification of the constituents. The structures were elucidated by chemical evidence and spectral methods. Results:A new stigmasterol glycoside,(24R)-stigmastan-3β,5α,6β-triol 3-O-β-D-glucopyranoside (1),together with three known phenolic glycosides:6-O-p-coumaroyl-D-glucopyranose (2),6-O-caffeoyl-D-glucopyranose (3),1-O-(E)-caffeoyl-β-D-gentiobiose (4) were obtained and identified by spectroscopic methods. Conclusion:All compounds were isolated from Lygodiaceae for the first time.
