Fund Project: The author is grateful to Ping Lang (Department of Analysis) for the measurement of IR, CD and NMR spectra.

Two new flavanone glycosides 1 and 2 were isolated from the aerial parts of Macrothelypteris torresiana (Gaud.) Ching. The structures of two products were identified as (2S)-5,7,2',5'-tetrahydroxyflavanone-20-O-β-D-6"-O-acetylglucopyranoside and (2S)-5,7,2',5'-tetrahydroxyflavanone-2'-O-β-D-glucopyranoside on the basis of their chemical and spectral analysis, respectively.
