5,5'-Dihydroxy-2',4'-dimethoxy-7-[(6-O-β-d-apiofuranosyl-β-d-glucopyranosyl)-oxy]isoflavone (1) was isolated as the major constituent of Dalbergia vacciniifolia root bark ethanol extract together with the four known compounds 5,7-dihydroxy-2',4',5'-trimethoxyisoflavone (3), 5,7-dihydroxy-2',4'-dimethoxy-isoflavone (4), 5-hydroxy-2',4',7-trimethoxyisoflavone (5) and 7-hydroxy-2',4',5'-trimethoxy...

This study evaluated, using replicated laboratory bioassays, the toxicities of the crude aqueous and ethanolic extracts of Dalbergia sissoo Roxb. 1832 (family Leguminosae) fruits, leaves, roots and stem bark against egg masses of Biomphalaria pfeifferi (Krauss, 1848), the snail intermediate host of Schistosoma mansoni (Sambon, 1907) in Nigeria. Viable 0-24 hr-old embryonated egg masses were sep...

Two flavonoids, 4,2',5'-trihydroxy-4'-methoxychalcone (1) and (2S)-6,7,4'-trihydroxyflavan (2), along with fourteen known flavonoids and two other known arylbenzofurans were isolated from the heartwood of Dalbergia odorifera. The structure of compounds 1 and 2 were established by spectroscopic (NMR and MS) analyses. Of the isolates, eight compounds (1, 4, 7, 10, 12, 14, 15, 17) were found to ha...

BACKGROUND AND AIMS Dalbergia nigra is one of the most valuable timber species of its genus, having been traded for over 300 years. Due to over-exploitation it is facing extinction and trade has been banned under CITES Appendix I since 1992. Current methods, primarily comparative wood anatomy, are inadequate for conclusive species identification. This study aims to find a set of anatomical char...

For the first time, current review fully provides information on phytochemicals, applications, and pharmacological aspects relating to 3 Dalbergia species, Siamese Rosewood ( cochinchinensis Pierre ex Laness.), Indian D sissoo Roxb.), Brazilian nigra (Vell.) Benth.). Based chromatographic separation, phytochemical studies these plants have, date, resulted in isolation structural elucidation of ...
