Abstract: Psoralea corylifolia L. (Fabaceae) is a widely used medical plant in China. This study was designed to screen and identify bioactive compounds with anticancer activity from the seeds of Psoralea corylifolia L. One volatile fraction (fraction I) and three other fractions (fraction II, III, IV) from methanol extraction of P. corylifolia L. were obtained. Bioactivities of these fractions were evaluated by the cytotoxicity on KB, KBv200, K562, K562/ADM cancer cells with MTT assay. Major components in the active fraction were identified by HPLC/MSn. Fraction IV significantly inhibits the growth of cancer cells in a dose-dependent manner. The IC50 values were 21.6, 24.4, 10.0 and 26.9, respectively. Psoralen and isopsoralen, isolated from fraction IV, were subject to bioactive assay and presented a dose-dependent anticancer activity in four cancer cell lines (KB, KBv200, K562 and K562/ADM). The IC50 values of psoralen were 88.1, 86.6, 24.4 and 62.6, which of isopsoralen were 61.9, 49.4, 49.6 and 72.0, respectively. Apoptosis of tumor cell significantly increased after treated with psoralen and isopsoralen. Induction of apoptotic activity was confirmed by flow cytometry after staining with Annexin V/PI. These results suggested psoralen and isopsoralen contribute to anticancer effect of P. corylifolia L.

Abstract: “Bakuchi oil” is Ayurvedic medicinal oil prepared from the dried fruits of Psoralea corylifolia L. (Fabaceae) and Sesame oil is used widely in the treatment of vitiligo in Sri Lanka. The standardization of the oil is important for its safe and effective clinical use. A method was developed to quantitatively extract psoralen, the major photoactive compound in the oil and quantify it by TLC fluorodensitometry. The precision of the method was 4.3% CV (n = 6). A TLC fingerprint of the oil highlighting six fluorescent secondary metabolites of Psoralea corylifolia (psoralen, isopsoralen, corylin, psoralidin, dehydroisopsoralidin and isobavachalcone) was also developed. Of these dehydroisopsoralidin is being reported for the first time from a natural source. Analysis of the oil indicates that Bakuchiol, a major secondary metabolite of Psoralea corylifolia is not incorporated into the medicinal oil.

Abstract: The main objective of this study is to determine anti-inflammatory and antimicrobial activity of hexane extract of seeds of of Psoralea corylifolia Linn. Anti-inflammatory activity of Psoralea corylifolia Linn. was evaluated by carrageenan induced rat paw oedema assay. The seed of plant was extracted in soxhlet apparatus using hexane as solvent. Nine healthy swiss albino rats of either sex were divided into 3 groups, each consisting of 3 rats. The evaluation was done by Hind paw method and compared with standard and control groups. Further, the antimicrobial activity of Psoralea corylifolia Linn was studied by Disc diffusion method using different gram positive and gram negative bacterial and fungal strains, which showed that it has prominent activity compared with the standard used. The hexane extract of Psoralea Corylifolia showed significant anti- inflammatory activity (44%) when compared with the standard (55%). For antimicrobial activity, zone of inhibition were found to be in concentration of 5μg / ml for bacterial strains and 4μg / ml for fungal strains.

Abstract: High frequency shoot regeneration and evaluation of product synthesis at various stages in Psoralea corylifolia were investigated. In vitro regenerated shoots were induced from germinated seedling on MS medium supplemented with 2, 4, 8, 20 and 40 μM of thidiazuron and N 6–benzylaminopurine. The results revealed that optimum concentrations of thidiazuron (8 μM) into the medium increased shoot regeneration frequency. Root differentiation was achieved from regenerated shoots on growth regulator free MS medium with frequency of 91.2% and mean number of 4.5 roots per shoot. High concentrations of Indole-3-aceticacid (IAA) into the rooting medium resulted in slow growth. Regenerated shoots and roots enhanced isoflavones production compared to field grown plants. A reverse phase high performance liquid chromatography analysis revealed that in vitro regenerated shoots accumulated 0.85% dry wt of daidzein and 0.06% dry wt of genistein. Maximum daidzein (1.23% dry wt) and genistein (0.38% dry wt) were accumulated by roots which obtained from regenerated shoots, which is 6.3-fold more daidzein and 77-fold more genistein respectively than field grown plants. The regeneration protocol developed successfully in this study showed the possibility for rapid propagation of P. corylifolia and enhanced isoflavones production.

Abstract: The insecticidal activity of essential oils obtained from DCM extracts of Psoralea corylifolia (Fabaceae) against pupa of Epilachna insect was investigated in a series of laboratory experiments. Insecticidal activity was determined at 24 ± 4 C and 68 ± 5% R.H., in dark conditions. The DCM extracts of the dried seeds of the plants were subjected to Column chromatography and the oil obtained was then subjected to hydrodistillation using a Clevenger type apparatus. The major components in these essential oils are identified using GC-MS spectroscopy and their insecticidal activity was tested. The predominant components in the oil of Psoralea corylifolia are toluene, alpha-pinene, L-beta-pinene, beta-pinene, 3-carene, limonene, Gamma terpinene, terpinolene, alpha santolina alcohol, 4-terpineol, Cyclohexene, 1-methyl-4-(1-methyl ethenyl), caryophyllene, alpha caryophyllene, thumbergene. The mortality rate of the agricultural pests was checked against 1%, 5% and 10% conc. of essential oil. The essential oil from Psoralea corylifolia shows strong toxic effect against pupa of Epilachna insect. Finding insecticidal activity is of great importance as using plant extracts as insecticides, are biodegrable and do not leave toxic residues results in better crop and better human health.

Abstract: Objectives: Psoralea corylifolia L. (seeds) and Plumbago zeylanica L. (bark) were combined in the ratio of 8: 2 and named as “Swithranasini” and used for the treatment of skin diseases in ayurvedic medicine. Scientific studies validating the therapeutic properties for this indigenous medicine are lacking. This study focused on determining antimicrobial efficacy of methanol and butter milk extracts along with antioxidant efficacies of these plant parts independently and in combination. Materials and Methods: Antimicrobial activity was tested against seven pathogenic bacteria and six pathogenic fungi by measuring the zone of inhibition. In vitro antioxidant activities were assayed by 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging method and Ferric reducing antioxidant power (FRAP) method. Results: Individual extracts of the two plants showed better zone of inhibition (12- 40 mm) when applied alone but the activity was more when applied in combination (18-50 mm) against the tested pathogens. DPPH activity of methanol extracts showed higher radical scavenging activity when compared with the positive control, ascorbic acid. The IC50 values are 442.080, 457.825, 432.040 and 394.563 ug/ml for A, B, A+B and ascorbic acid respectively. The FRAP method also showed excellent antioxidant potential in combination (85.454 mg of Gallic acid equivalents/g) when compared with individual extracts A (78.571 mg GAE/g) and B (75.472 mg GAE/g).Conclusion: The results validate the potent use of “Swithranasini” against skin infections and results are an evidence for the existence of synergism among the compounds.
