The notable resistance to decay of rosewoods (usually from the genera Dalbergia and Machaerium) is due to the presence of several types of phenolic compounds the neoflavonoids are major among these (Donnelly, 1982 Donnelly and Cannon, 1986). [Pg.187]

Machaerium scleroxylon) in a hobbyist handling the wood. Plants reported to cause erythema multiformelike eruption include poison ivy (Toxicodendron) (Schwartz and Downham 1981 Mallory et al. 1982), primula Primula obconica) (Hjorth 1966) and mug-wort (Artemesia vulgaris) (Kurz and Rapaport 1979). Mallory et al. (1982) reported urticarial eruptions with black deposits on the skin of four patients with Toxidocendron radicans dermatitis. Urticaria, erythema multiforme-like eruptions, in a patient from Rhus dermatitis was reported by Schwartz and Down-ham (1981). They recommended that patients with such reactions should be screened for systemic involvement as previous reports have shown that nephritis can be an associated feature (Meneghini and AngeUni 1981 Fisher 1986). [Pg.276]

Flavonoids of wood are covered separately in Sect. 7.5. Neoflavanoids as well as other rearranged or condensed flavanoids and related compounds are also significant constituents of some wood species. They will only briefly be discussed in this section. They contribute to the properties of wood and can serve as taxonomic markers. Representative neoflavanoids are dalbergin (47) and related compounds of Dalbergia and Machaerium spp. (Leguminosae) (27, 28, 87). [Pg.526]

Other related isoflavonoid types are known that may co-occur with one or more isoflavones in legume heartwoods. Related pterocarpans and isoflavans, for example, accompany isoflavones in the wood of various Dalbergia and Machaerium species (see Sect. 7.S.3.3). Again, the isoflavone quinone bowdichione (42) and the pterocarpan homopterocarpin, (46) occur with the isoflavones genistein (34) and calycosin (3 -hydroformononetin) (111) in the heartwood of Bowdichia nitida,... [Pg.550]

While flavans are quite rare in nature, the isomeric isoflavans are more numerous (there are 39 of them), and they occur fairly widely, at least in members of the Leguminosae. Isoflavans are optically active and compounds with both the R-and 5- configuration at C-3 have been described. Two typical isoflavans are equol (49) which occurs in the heartwood of Millettia pendula but is better known as a urinary metabolite in mammals of the isoflavone formononetin (109) and (-)-duartin (50) present in the heartwood of several Machaerium species. Isoflavans (and pterocarpans) occur in a different context than wood chemistry in the... [Pg.551]

Leguminosae they are also commonly formed in leaf tissue as phytoalexins, in response to microbial infection (21). TWo structural types closely related to the isoflavans are the isoflavan quinones and the isoflavenes. Examples are mucro-quinone (51) from woods of Machaerium mucronulatum and Cyclolobium claus-seni, and haginins B and D (52a, 52b) from wood of Lespedeza cyrtobotrya. [Pg.552]

The distribution of these phenolics in Dalbergia and Machaerium woods is indicated in Table 7.5.8. The two genera are close morphologically, and it is therefore interesting that they merge into each other chemically, with no sharp cut-off... [Pg.564]
