Antioxidant activities of natural phenolic components from Dalbergia odorifera T. Chen

Food Chemistry, 2000
Abstract The antioxidant activities on oil of natural phenolic components extracted from Dalbergia odorifera T. Chen were investigated. A new benzophenone 2,4-dihydroxy-5-methoxybenzophenone ( 1 ), together with eight known components, were isolated. The eight components were identified by chemical and spectroscopic methods as 2′,3′,7-trihydroxy-4′-

Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica, 2014
Fourteen compounds were isolated from Dalbergia odoriferae and purified by repeated column chromatography on silica and sephadex LH-20 gel and structurally identified by spectral analysis. These compounds were identified as 4, 9-dimethoxy-3-hydroxypterocarpan (1), medicarpin (2), 2', 4', 5-trihydroxy-7-methoxyisoflavone (3), 2', 3', 7-trihydroxy-4 ...

Neoflavonoids from Dalbergia odorifera

Phytochemistry, 1997
Abstract Two new neoflavonoids, 3′-hydroxymelanettin and 3′-hydroxy-2,4,5-trimethoxydalbergiquinol, were isolated from the heartwood of Dalbergia odorifera, together with the known compounds, dalbergin, melanettin, stevenin, 4-methoxydalbergione, and cearoin. The structures of the new compounds were established by spectral methods, especially 2D NMR.

Five new sesquiterpenoids from Dalbergia odorifera

Fitoterapia, 2014
Five new sesquiterpenes (1-5) along with ten known ones were isolated from the heartwood of Dalbergia odorifrea T. Chen. Their structures were determined by spectroscopic techniques including MS, UV, IR, 1D and 2D NMR. Bioassay results showed that compounds 1 and 9 had inhibitory effect on Candida albicans, and compound 9 exhibited inhibitory effects ...

Three new phenolic compounds from Dalbergia odorifera

Journal of Asian Natural Products Research, 2014
Three new phenolic compounds (1-3) were isolated from the heartwood of Dalbergia odorifera T. Chen. (Leguminosae). Their structures were established based on spectroscopic methods including 1D and 2D NMR (HSQC, COSY, HMBC and ROESY). Compound 2 exhibited cytotoxicity against BEL-7402 tumor cell lines.

Antioxidant properties of butein isolated from Dalbergia odorifera

Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1998
The antioxidant properties of butein, isolated from Dalbergia odorifera T. Chen, were investigated in this study. Butein inhibited iron-induced lipid peroxidation in rat brain homogenate in a concentration-dependent manner with an IC50, 3.3+/-0.4 microM. It was as potent as alpha-tocopherol in reducing the stable free radical diphenyl-2-picrylhydrazyl (

Pharmacokinetics and molecular docking of the cardioprotective flavonoids in Dalbergia odorifera

Journal of Separation Science, 2023
The purpose of this research was to investigate the cardioprotective effects and pharmacokinetics of Dalbergia odorifera flavonoids. The cardioprotective effects were detected by hematoxylin‐eosin staining histopathological observations and the detection of myocardial enzymes by kits in serum, peroxidation and antioxidant levels and ATPase activities ...
