The genus Dalbergia contains many valuable timber species threatened by illegal logging and deforestation, but knowledge on distributions and threats is often limited and accurate species identification difficult. The aim of this study was to apply DNA barcoding methods to support conservation efforts of Dalbergia species in Indochina. We used the recommended rbcL, matK and ITS barcoding marker...

Illegal selective logging of tropical timber is of increasing concern worldwide. Madagascar is a biodiversity hotspot and home to some of the world's most sought after tropical timber species. Malagasy rosewoods belong to the genus Dalbergia (Fabaceae), which is highly diverse and has a pantropical distribution, but these timber species are among the most threatened as a consequence of intensiv...

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...

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...

Dalbergia sissoo Roxb (Indian rosewood) is an important tree species belonging to the family papilionaceae. It is a medium to large‐sized, gregarious deciduous tree, attaining a height up to 30 m and a girth up to 2•5 m in a favorable climate (sub‐tropical and tropical zones). According to Champion & Seth [1], the Shisham tree is a characteristic species of Khair-sissoo (Acacia catechu‐Dalbergi...

Dalbergia melanoxylon Gill. & Perr. known as African Blackwood or Mpingo in Swahili is a flowering plant in the family Fabaceae known to be an economically important tree with high-quality wood and being one of the most expensive timbers in the world (Jenkins et al. 2002, Ball, 2004). D. melanoxylon presently exploited for international trade is the most precious heartwood in the world (Ball, 2...

Dalbergia latifolia commonly known as bilayatti shisham (Fabaceae) is a medicinal plant. The dry bark is brown coloured astringent characters. Traditionally various species are reported to be used as aphrodisiac, abortifacient, expectorant, anthelmentic, antipyretic, appetizer, allays thirst, vomiting, burning sensation, cures skin diseases, ulcers Ayurvedic practice, bark is used as leucoderma...

DNA barcoding enables precise identification of species from analysis of unique DNA sequence of a target gene. The present study was undertaken to develop barcodes for different species of the genus Dalbergia, an economically important timber plant and is widely distributed in the tropics. Ten Dalbergia species selected from the Western Ghats of India were evaluated using three regions in the p...

The antioxidant activities of 24 isoflavonoids that were previously isolated as pure compounds from Dalbergia parviflora were evaluated using three different in vitro antioxidant-based assay systems: xanthine/xanthine oxidase (X/XO), ORAC, and DPPH. The isolates consisted of three subgroups, namely isoflavones, isoflavanones, and isoflavans, each of which appeared to have diversified substituen...
