| Nat Prod Commun. 2013 Feb;8(2):181-2. | | Phenolic glycosides from Lindera obtusiloba and their anti-allergic inflammatory activities.[Pubmed: 23513723] |
METHODS AND RESULTS:
Eight phenolic glycosides, tachioside (1), Isotachioside (2), koaburaside (3), 2,6-dimethoxy-4-hydroxyphenyl-1-O-beta-D-glucopyranoside (4), 4,6-dihydroxy-2-methoxyphenyl-1-O-beta-D-glucopyranoside (5), a mixture of erigeside C (6a) and salidroside (6b), and 6-hydroxyphenyl)-1-O-beta-D-glucopyranoside (7) were isolated from the stems of Lindera obtusiloba Blume. | | Zhongguo Zhong Yao Za Zhi. 2010 Nov;35(22):3007-9. | | Chemical constituents from Hydrangea paniculata.[Pubmed: 21355271] | 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.
METHODS AND RESULTS:
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).
CONCLUSIONS:
Compounds 1 - 7 were isolated from H. paniculata for the first time. |
