Rosewood's inner wood chemistry helps confirm its family tree
Ethnobotany
The rosewood furniture and instrument trade depends on being able to tell true Dalbergia species apart from look-alike substitutes, and chemical fingerprints like this one are exactly how botanists and customs officials make that call.
Researchers cracked open the dense, dark heartwood of a rosewood tree called Dalbergia bariensis and pulled out its natural chemical compounds. Comparing those compounds to chemicals found in related rosewood species helps scientists figure out how closely different trees are related, almost like a chemical family photo.
Key Findings
1
Multiple chemical compounds were isolated and structurally identified from the heartwood of Dalbergia bariensis
2
Compound profiles were compared against related Dalbergia species to assess taxonomic relationships
3
Findings support using heartwood chemistry as a tool for classifying and distinguishing rosewood species

Technical Summary
Chemists examined the heartwood of a Southeast Asian rosewood tree, Dalbergia bariensis, and identified the natural chemical compounds inside it, information that helps botanists confirm how this tree relates to other rosewood species.
Rosewood is any of a number of richly hued hardwoods, often brownish with darker veining, but found in other colours. It is hard, tough, strong, and dense. True rosewoods come from trees of the genus Dalbergia, but other woods are often called rosewood. Rosewood takes a high polish and is used fo...
