The mono-, di-, and tri-O-methyl ether derivatives of 2-amino-2-deoxy-D-glucopyranose have been analyzed by gas–liquid chromatography of their fully acetylated 2-acetamido-2-deoxy-D-glucitol derivatives which were prepared from the glycoses by reduction with sodium borohydride followed by acetylation with acetic anhydride. The methyl ethers of 2-amino-2-deoxy-D-glucopyranose were also characterized by degradation with ninhydrin to the corresponding methyl ether derivatives of D-arabinose which were identified by paper chromatography.

The major constituent of the yellow frond exudate of the fern Notholaena sulphured was identified by spectroscopic methods as 3,5,2′-trihydroxy-7-methoxy-8-acetoxy flavone and its structure was confirmed by synthesis. This novel natural flavonoid was also detected in the frond exudate of five other Notholaena species. In the yellow form of N. sulphurea, the rare 5,2′- dihydroxy-7,8-dimethoxy flavone was also found, along with some trivial flavonoids. The white form of N. sulphurea produces three dihydrochalcones that are accompanied by some kaempferol methyl ethers and apigenin-7-methyl ether. The 3-acetoxy as well as the 3-butyroxy and the 4′- butyroxy derivatives of 7-methyl aromadendrin were also identified in this material. One of them was shown to belong to the extremely rare group of 3-cis-dihydroflavonols.
