Résumé

Two new phenylpropanoid glycosides named cuneataside E () and cuneataside F (), were isolated from the aerial parts of(Dum. Cours.) G. Don, whose structures wereandisomer, respectively. Their structures were elucidated on the basis of comprehensive spectroscopic analysis (UV, IR, HR-ESI-MS, 1D and 2D NMR). Inbioassays at 10 μmol/L, compoundshowed moderate hepatoprotective activity against-acetyl--aminophenol (APAP)-induced toxicity in HeG2 cells.

Résumé

In order to study the chemical constituents of the leaves of Tripterygium wilfordii and provide references for the bio-active study, we isolated nine compounds from the dried leaves of Tripterygium wilfordii. Their structures were determined by application of spectroscopic (NMR, MS) and chemical methods. These compounds were isolated and identified as (+)-lyoniresinol (1), (+)-isolariciresinol (2), burselignan (3), dibutyl phthalate (4), cyclo-(S-Pro-R-Phe) (5), cyclo-(S-Pro-R-Leu) (6), cyclo-(S-Pro-S-Ile) (7), 3-hydroxy-1-(4-hydroxy-3,5-dimethoxyphenyl)-1-propanone (8) and daucosterol (9). Compounds 1-3, 5-8 were isolated from this plant for the first time.

Résumé

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.
