Dalnigrin, a neoflavonoid marker for the identification of Brazilian rosewood (Dalbergia nigra) in CITES enforcement

Phytochemistry, 2010
International trade in Brazilian rosewood, Dalbergia nigra (Vell.) Allemão ex Benth., is regulated by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). One problem in enforcing these regulations is the difficulty in distinguishing the wood of D.

Alterations in seed reserves of Dalbergia nigra ((Vell.) Fr All. ex Benth.) during hydration [PDF]

Journal of Seed Science, 2013
Seed imbibitions is the first stage of the germination process and is characterized by the hydration of tissues and cells and the activation and/or induction of the enzymes responsible for mobilizing reserves for respiration and the construction of new cell structures. The objective of this study was to investigate the alterations in reserve substances

Diversity and genetic structure in a mini-garden of Dalbergia nigra: A tree threatened with extinction in the Atlantic Forest

Plant Gene, 2021
Abstract Maintaining genetic variability within rare or threatened species is essential for the development of conservation and restoration strategies. Therefore, the objective of this study was to characterize the diversity and genetic structure in Dalbergia nigra mini-garden. DNA samples from 90 individuals of D.

A New Isoflavone Glycoside from Dalbergia nigra

Journal of Natural Products, 1998
The new 5-hydroxy-6, 7-dimethoxy-4'-O-(6-O-D-apio-beta-D-furanosyl-beta-D-glucopyranosyl)i soflavone (1) has been isolated from Dalbergia nigra. The structure was elucidated using extensive spectroscopic analysis (1D and 2D NMR, MS, IR, UV).

Nitric oxide on the germination of Dalbergia nigra seeds with low vigor

2019
Nitric oxide is a compound that participates in many plant physiological processes, among which works by stimulating the germination both under normal and under stress conditions. This study aimed to investigate the effectiveness of potassium nitrate (KNO3) and sodium nitroprusside (SNP), forming nitric oxide, on the germination of seeds of low vigor ...
