title: [Chemical constituents from Hydrangea paniculata].
abstract: In order to study the chemical constituents of the plant of Hydrangea paniculata and provide reference for the study of the bioactive substances, we isolated nine compounds from the dried branches of H. paniculata. Their structures were determined by application of spectroscopic (NMR, MS) and chemical methods. These compounds were identified as skimmin (1), isotachioside (2), 8-methoxy-7-O-beta-D-glucopyranosyloxy coumarin glycoside (3), scopolin (4), 1-(alpha-L-rhamnosyl-(1 --> 6) -O-beta-D-glucopyranosyloxy) - 3, 4, 5-trimethoxybenzene (5), apiosylskimmin (6), umbelliferone (7), scopoletin (8), 7-hydroxy-8-methoxycoumarin (9). Compounds 1 - 7 were isolated from H. paniculata for the first time.
