[Two new compounds from Dryopteris fragrans]
Objective:
To study the chemical constituents of Dryopteris fragrans.
Methods:
Two new compounds were isolated and purified from this plant by column chromatography and their structures were elucidated through spectroscopic analysis.
Results:
Two new compounds were identified as trans-S-trans-p-hydroxy cinamic acid-9-beta-D-xylpyranosyl (1 --> 2) -beta-D-glucopyranosyl ester, methyl-2-eth-yl-6-((3, 4, 5-trihydroxy-6-(hydroxymethyl) tetrahydro-2H-pyran-2-yl) oxy) benzoate.
Conclusion:
Compounds 1 and 2 are new and named fragranoside J and fragranoside K.
