Radial variation in pernambuco (Caesalpinia echinata) wood properties
IAWA Journal, 2017Caesalpinia echinata Lam. (pernambuco or pau-brasil) is recognized as the premier raw material for manufacturing stringed instrument bows. Several studies have identified properties considered important in determining the suitability of pernambuco wood for bow manufacture including density, modulus of elasticity (MOE), and, possibly, microfibril angle (

The heartwood of Caesalpinia echinata Lam. (Leguminosae) (commonly called brazilwood) is used for violin bow manufacture due to the unique vibrational and physical properties found in the wood. In the present work, the effects of Pycnoporus sanguineus (white-rot fungus), Gloeophyllum trabeum (brown-rot fungus), Chaetomium globosum (soft-rot fungus ...

Fourteen cassane-type diterpenoids, echinalides H-U, were isolated from the stem of Caesalpinia echinata Lam. (Leguminosae). The structures of the echinalides were elucidated by spectroscopic investigation, including 2D NMR spectroscopic analysis. The structures of echinalide H and echinalide T were further confirmed by single-crystal X-ray diffraction.

Caesalpinia echinata (brazilwood or Pernambuco wood) comprises a complex of three morphological leaf variants, characterized by differences in the number and size of the pinnae and leaflets, and occurring in allopatric and sympatric populations. The present study evaluates the utility of the chloroplast DNA trnL intron in a phylogenetic analysis of the
