Objective:To investigate chemical constituents from Chinese herbal medicine Hydrangea macrophylla.Method:The compounds were separated and purified by column chromatography over silica gel,ODS,and preparative HPLC.Their structures were identified by spectral methods including 1H,13C-NMR and MS.Result:Eleven compounds were isolated and identified as zeorin,hopane-6,22-diol (1),botulin (2),betulinic acid (3),2-ethyl-3-methyl-maleimide-N-β-D-glucopyranoside (4),uridine (5),thymidine (6),adenosine (7),nicotinamide (8),methyl pyroglutamate (9),hydrangenol (10) and hydrangenol-4'-O-β-D-glucopyranoside(11),respectively.Conclusion:Compounds 1-4 and 7-9 were obtained from the genus Hydrangea for the first time.
