“…Method 1: acid hydrolysis after methanolic extraction. The following procedure had been used in previous research (Innocenti et al, 1989(Innocenti et al, , 1991 concerning new potential sources of furanocoumarins on the assumption that in plant tissues glycosylated precursors of furanocoumarins might be present. The samples were extracted with methanol in a Soxhlet apparatus for 48 h, and the solvent was evaporated.…”

The occurrence of bound coumarin derivatives in the Fabaceae has already been demonstrated. In an attempt to determine the yield of furanocoumarins following exhaustive recovery from Psoralea bituminosa, three different hydrolytic procedures have been employed. Method 1 involved the methanolic extraction of plant material followed by acid hydrolysis of the remaining plant material; methods 2 and 3 involved preliminary hydrolysis by acid or enzyme, respectively, followed by solvent extract. The lowest furanocoumarin recovery was obtained using the first extraction procedure, whilst the highest was obtained using the extraction procedure with enzymatic hydrolysis of bound forms (method 3). The linear isomer psoralen is more effectively recovered by the specific enzymatic hydrolytic method, with an average increase of the psoralen:angelicin ratio of about 20%. Although the preliminary acid hydrolysis (method 2) is less effective than the enzymatic one, it is a faster and less expensive procedure and it could be suitable and profitably used for extracting furanocoumarin from plant material on a large scale.

“…The nutritive value of B. bituminosa in terms of forage composition and digestibility has proved similar to or even better than that of other wild legumes 3, 10. However, the aerial part of this species may contain a high concentration of furanocoumarins, of which psoralen and angelicin are the most abundant compounds 11, 12. A substantial proportion of the furanocoumarin content is located on the surfaces of leaves, fruits, embryos and young seedlings 12–14.…”

“…These substances could be harmful to animals, being responsible for contact photodermatitis,13 in addition to possibly limiting forage intake 9. On the other hand, because they elicit skin photosensitisation, there is an increasing demand for furanocoumarins, which are widely used in cosmetics, for suntanning products and in dermatology for the photochemotherapy of some skin diseases 11. The presence of other secondary compounds (e.g.…”

Variation in forage quality and chemical composition among Italian accessions of Bituminaria bituminosa (L.) Stirt.

et al. 2007

Native Bituminaria bituminosa (L.) Stirt. accessions from central and southern Italy were evaluated for chemical composition to assess their nutritional value as forages. The germplasm was evaluated subjectively ex situ for intensity of 'oil' smell and analysed for fibre fraction, crude protein and water-soluble carbohydrate contents as well as furanocoumarin (psoralen and angelicin) concentration. Total phenolics and their antioxidant activity were also evaluated. The quality parameters indicated this species as a good forage source, showing nutritive values similar to those of other wild legume species. Psoralen and angelicin contents ranged from 2.8 to 5.4 and from 2.3 to 4.7 mg g −1 dry weight respectively, while total phenolic concentrations were between 11.2 and 13.5 mg g −1 dry weight. Correlations among forage quality parameters, chemical components and climatic features at sites of origin were also assessed.

“…Biosynthetically, they are mainly originated from shikimic acid pathway, with the intermediated of cinnamic acid. In the case of Bituminaria bituminosa, the presence of two furanocoumarins has been reported by different authors as psoralen (linear furanocoumarins) and angelicin (angular furanocoumarins) (Innocenti et al, 1991(Innocenti et al, , 1997Méndez et al, 2001;Tava et al, 2007). However, little information exits concerning the presence of these secondary compounds in the genus Cullen.…”
