ABSTRACT

Objective:

To investigate the chemical constituents of the leaves of Hydrangea macrophylla.

Methods:

The chemical constituents were separated and purified by various isolation methods (silica gel, ODS, and HPLC column chromatography), and their structures were determined by the analysis of spectral data (1H-NMR, 13C-NMR, and MS).

Results:

Eleven compounds were obtained and elucidated as following secologanin ethyl methyl acetal (1), secologanin dimethyl acetal (2), secoxyloganin (3), 7-deoxyloganic acid (4), loganic acid (5), 8-epi-loganin (6), loganin (7), 7-dehydrologanin (8), sweroside (9), epi-vogeloside (10), and vogeloside (11).

Conclusion:

Compound 1 is a new compound, named as macrophyoside. Compounds 3 and 8 are isolated for the first time from the plants of Hydrangea Linn.
