Study of allelopathic interaction of alkaloid extracts of Peganum harmala plant on seed germination Ocimium basilicum

Abstract

Effect of alkaloid extract of Peganum harmala seeds on Ocimium basilicum germination was investigated at different concentrations viz., 0, 10, 50, 250 and 500 µ g/L, The effect of glycoside chemical compounds varied between the control and treatment groups. The number of Alkaloid compounds of Peganum harmala revealed 78 chemical compounds, The main compounds in control treatment were 71 whereas the treatment recorded63, 49, 41, and42 chemical compounds in10, 50, 250and500 µ g/L, respectively. The main compounds in control Treatment were beta.-Carboline, 5-methoxy- (15.07422) was recorded, and the compound the lowest percentage of Dodecanoic acid 0.166245, the main compound in10 Concentration Hexadecanoic acid, 2-hydroxy-1-(hydroxymethyl) ethyl ester (19.09388646) ,and the compound the lowest percentage Phytyl, 2-methylbutanoate (0.194346544) , the main compound in50 Concentration Hexadecanoic acid, 2-hydroxy-1-(hydroxymethyl)ethyl ester(23.70323231) and the compound the lowest percentage Neophytadiene(0.291812048 )the main compound in250 Concentration Octadecanoic acid, 2,3-dihydroxypropyl ester(12.89648812), 9,12,15-Octadecatrienoic acid, methyl ester, (Z,Z,Z)-( 0.298995853) the main compound in500 Concentration Harmine(29.0666794) dl-.alpha.-Tocopherol(0.349489537).
