Objective: To evaluate antibacterial and antifungal activity of hexane and methanol extracts of Psoralea Corylifolea Seed. Method: Psoralea Corylifolia seeds were extracted by using different solvents hexane and methanol and the test extracts were assayed for antibacterial and antifungal activity. The antibacterial activity was tested against Staphylococcus aureus and antifungal activity was tested against Candida albicans and Aspergillus niger by agar well diffusion method and measuring the zone of Inhibition. Results: The hexane and methanol extracts of Psoralea corylifolia seed was very effective against Staphylococcus aureus, Candida albicans and Aspergillus niger. The results showed unique characters of the plant in inhibiting bacterial and fungal growth. Conclusion: In the present study antibacterial and anti fungal activity of hexane and methanol extracts of psoralea corylifolea seed was confirmed.

The compounds containing thiazole, thiadiazole, oxazole, oxadiazole, imidazole, pyrimidine, pyridine & benzothiazole rings have been found to exhibit broad spectrum of biological activities.Derivatives of 1, 2, 4-thiadiazole and 1, 2, 4-thiadiazolidines exhibit antibacterial and antifungal activity1. Thiazolyl guanidines2 and various substituted aryl guanidine’s have been found to exhibit antibacterial & antifungal activities3.Keeping all these views in mind attempts were made to synthesized some new 1,3-di methyl Substituted Guanidine.In the present work 2,4 Dimethyl -3,5-(di Aryl imino)-1,2,4-thiadiazolidines were prepared by nitrous acid oxidation of N-methyl –N Aryl thiourea4 & 2,4 dimethyl-3,5-(diaryl imino)-1,2,4-thiazolidines were converted to corresponding 1,3 di methyl substituted guanidine’s by their acid catalyzed re-arrangment5.(Scheme-1)Antibacterial & Antifungal activity of the title compounds were evaluated against two bacteria, E.coli & lactobacillus & two fungi, A.Brassicicola & Aspergillus Niger. N=methyl-N`-Aryl thiourea (1-10) were prepared by refluxing a mixture of different 2-Amino Heterocyclic moieties with methyl iso thiocyanate in Ethanol.A mixture of compound (1-100 and conc. HCl, ethanol was added drop wise & under stirring to a solution of NaNO2 in water afforded 2, 4-dimethyl-3,5-(di Aryl imino)-1,2,4-thiadiazolidine (11-20) afforded 1,3 di methyl substituted guanidine’s (21-30). Structures of the compounds were established by elemental analysis & spectral data.
