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: Psoralea corylifolia known as “Babchi” is a medicinal plant for the treatment of skin diseases. In India, indigenous herbal remedies such as Ayurveda and other Indian traditional medicines have since ancient times used plants in treatment of various disorders. In our present investigation preliminary phytochemical analysis of Psoralea corylifolia has been evaluated for the presence of bioactive constituents using various polarity solvents including hexane, butanol, ethanol and water. The phytochemical screening of the plant extracts revealed the presence of maximum compounds including carbohydrates, terpenoids, alkaloids, phenols, tannins, amino acid and proteins, cardiac glycosides. The results suggest that the ethanolic extract of Psoralea corylifolia has promising therapeutic potential and can be used as a base for the development of novel potent drugs in phytomedicine.

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: 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: 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.

Abstract: Background Indiscriminate use of synthetic insecticides to eradicate mosquitoes has caused physiological resistance. Plants provide a reservoir of biochemical compounds; among these compounds some have inhibitory effect on mosquitoes. In the present study the larvicidal, adulticidal and genotoxic activity of essential oil of Psoralea corylifolia Linn. against Culex quinquefasciatus Say was explored. Methods Essential oil was isolated from the seeds of P. corylifolia Linn. Larvicidal and adulticidal bioassay of Cx. quinquefasciatus was carried out by WHO method. Genotoxic activity of samples was determined by comet assay. Identification of different compounds was carried out by gas chromatography- mass spectrometry analysis. Results LC50 and LC90 values of essential oil were 63.38±6.30 and 99.02±16.63 ppm, respectively against Cx. quinquefasciatus larvae. The LD50 and LD90 values were 0.057±0.007 and 0.109±0.014 mg/cm2 respectively against adult Cx. quinquefasciatus,. Genotoxicity of adults was determined at 0.034 and 0.069 mg/cm2. The mean comet tail length was 6.2548±0.754 μm and 8.47±0.931 μm and the respective DNA damage was significant i.e. 6.713% and 8.864% in comparison to controls. GCMS analysis of essential oil revealed 20 compounds. The major eight compounds were caryophyllene oxide (40.79%), phenol,4-(3,7-dimethyl-3-ethenylocta-1,6-dienyl) (20.78%), caryophyllene (17.84%), α-humulene (2.15%), (+)- aromadendrene (1.57%), naphthalene, 1,2,3,4-tetra hydro-1,6-dimethyle-4-(1-methyl)-, (1S-cis) (1.53%), trans- caryophyllene (0.75%), and methyl hexadecanoate (0.67%). Conclusion Essential oil obtained from the seeds of P. corylifolia showed potent toxicity against larvae and adult Cx. quinquefasciatus. The present work revealed that the essential oil of P. corylifolia could be used as environmentally sound larvicidal and adulticidal agent for mosquito control.
