“…Method 1 had been used in previous research and it represented an improvement (Innocenti et al, 1984) compared with simple methanolic extraction (Innocenti et al, 1977) which did not consider the possible occurrence, in plant material, of glycosylated precursors of furanocoumarins. However, method 1 proved to be unsatisfactory.…”

“…Psoralea bituminosa L., a very common Euro-Mediterranean species, formerly regarded as a poor natural source of the linear furanocoumarin psoralen and its angular isomer angelicin (Innocenti et al, 1977), showed high contents of bound furanocoumarins (Innocenti et al, 1993(Innocenti et al, , 1995 and therefore seemed to be a plant material that could be much more interesting than previously believed.…”

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 present work describes radiation-induced effects on vegetative, reproductive traits and psoralen content in Psoralea corylifolia L. The effects of gamma radiation on Psoralea seeds were investigated by exposing seeds with doses of 2.5, 5, 10, 15 and 20 kGy at dose rate of 1.65 kGyh -1 and studying the plant growth at three developmental stages: preflowering, flowering and post flowering (seed to seed) after irradiation. Irradiation with lower doses of gamma rays significantly improved vegetative traits while higher doses proved depressing for same parameters. Similar trend was followed in reproductive traits. Psoralen, showed highest concentration in seeds (7.56%) at 20 kGy and lowest in control roots (0.23%). Increment in psoralen was striking for higher gamma doses applied. These long-term changes in plant development may be attributed to alteration in plant genome induced by irradiation. The results show in depth development stimulation and enhancement of secondary metabolite in Psoralea corylifolia L. following low and high dose treatment respectively depicting the potential of gamma rays in plant biotechnology and metabolomics.
