[Chemical constituents of Eucommia ulmoides]
Objective:
To study the chemical compositions of Eucommia ulmoides.
Methods:
The compounds were isolated and purified from Eucommia ulmoides by silica gel column chromatography, Sephadex LH-20, MPLC packed with MCI gel and semi-preparative HPLC. The structures of these compounds were established on the basis of spectral analyses (1H-NMR, 13C-NMR and MS).
Results:
Thirteen compounds were obtained,and their structures were identified as betulin (1), syringin (2), pervoside A (3), glucosyringic acid (4), vanillic acid-beta-glucoside (5), geniposide acid (6), aucubin (7), geniposide (8), pinoresinol-4,4'-di-O-beta-D-glucopyranoside (9), syringaresinol di-O-beta-D-glucopyranoside (10), medioresinol di-O-beta-D-glucopyranoside (11), sucrose (12), and ethyl beta-glucopyranoside (13) on the basis of physical characteristics and spectral data.
Conclusion:
Compounds 3 - 5, 12 and 13 are isolated from this plant for the first itme.
