摘要

Psoralen bituminosa C.H. Stirton (syn. Bituminaria bi-tuminosa L.) is a perennial legume usually considered of low palatability because of the strong smell that can be emitted by oil glands located on its foliage. However the nutritive value of P. bituminosa in terms of forage composition and digestibility was proven similar to or even better than that of other legumes. The aerial part of this species may contain a high concentration of furano-coumarins, out of which psoralen and angelicin are the most abundant (Pe-cetti et al. 2007). These substances could be harmful to animals, being responsible for contact photodcrmatitis, in addition to possibly limiting forage intake. Nevertheless there are some examples of the utilisation of P. bituminosa either as green or dry forage. In the Canary Islands, it is grazed all year and also is collected from late spring to mid-summer to make hay used to feed goats (Ventura et al. 2009). In Israel P. bituminosa is grazed by cattle in particular in mid-spring, when the principal grasses become less palatable. In late spring, when the herbaceous species dry up, P. bituminosa becomes the only species with green leaves and cattle graze the whole plant intensively (Sternberg et al. 2006).

Bituminosa的营养值类似于甚至比其他豆类更好。该物种的空中部分可含有高浓度的呋喃 - 香豆素，其中牛肝菌和天使是最丰富的（PE-CETTI等，2007）。除了可能限制饲料摄入量之外，这些物质可能对动物有害，负责接触光学炎。然而，存在与绿色或干法腐烂的p. bituminosa的一些例子。在加那利群岛，全年放牧，也从春季到中午收集到中午，以制作用于饲料山羊的干草（Ventura等，2009）。在以色列中，沥青米莎在春天中养牛，当主要草变得不那么卑鄙时。在春天，当草本植物干涸时，P.Bituminosa成为唯一的绿叶和养牛的唯一物种，深受整个植物（Sternberg等，2006）。
