Abstract:
To study the chemical constituents of Nervilia fordii (Hance) Schltr., various chromatographic methods were used, including D101 macroporous resin, silica gel, ODS and preparative HPLC chromatographic techniques. A new labdane diterpenoid glycoside named as nervilifordoside A was isolated from 60% EtOH extract of Nerviliafordii. The structure of compound 1 was elucidated as 12, 17-epoxy-3-hydroxy-17-methoxy-labdan-13-en-16, 15-olide 3-O-alpha-rhamnopyranosyl-(1 --> 2)-O-beta-glucopyranoside on the basis of HR-MS, 1D and 2D NMR spectroscopic data as well as chemical methods.
