A heartwood pigment in Dalbergia cell cultures

Phytochemistry, 2001
In an extensive survey of the genera Baphia, Caesalpinia, Dalbergia, Haematoxylon, and Pterocarpus, we have identified a number of species whose cell cultures accumulated pigments similar to those in heartwood. Thirteen rosewood (Dalbergia) species produced a purple quinonemethide pigment in the callus that was apparently identical between the species.

Fungitoxicity of Chemical Analogs with Heartwood Toxins

Current Microbiology, 1998
Trans-stilbene and tropolone as chemical analogs with naturally occurring fungitoxic heartwood compounds were studied with respect to their fungitoxic potency. While stilbene showed no fungitoxic activity towards the fungi Aureobasidium pullulans var. melanogenum, Penicillium glabrum, and Trichoderma harzianum in the concentrations tested, the minimal ...
