摘　　要：Objective:To investigate the effects of Dracaena arborea(D.arborea) on the sexual behavior parameters in experienced type-1 diabetic rats.Methods:Aqueous and ethanol(100 and 500mg/kg respectively)extracts of dried root barks of D.arborea.sildenafil citrate(1.44 mg/kg),trimethylamine-N-oxide(TMAO,20 mg/kg)and distilled water(110 mL/kg.were orally administered to 4 weeks streptozolocin-induced diabetic rats.Mount latency and frequency(ML.MF),intromission latency and frequency(IL,IF) and post-ejaculatory interval(PEI) were measured by ejaculating series during 90 min once a week for 4 weeks.Glycemia was determined at the beginning and at the end of the treatment Results:D.arborea did not show any major antihvperglycemic effects.Compared to the control group,a significant(P<0.05-0.001)increase in MF and IF was noticed in rats treated with sildenafil citrate(89.71% and 90.07% respectively),aqueous(500 mg/kg.88.08%and 88.749;respectively) and ethanol(100 mg/kg;89.53%and 89.17respectively) extracts of D.arborea after two weeks(series 1) of treatment.ML,IL and PEI were significantly(P<0.05-0.001) decreased after 4 weeks of daily treatment[sildenafil citrate(96.31.96.31%and 34.98%),and D.arborea aqueous 500 mg/kg(94.33.94.33% and 66.609;i and ethanol extracts 100 mg/kg(96.98.97.089;and 64.26%)].Conclusions:These aphrodisiac potentials of D.arborea in experienced diabetic rats could be due to the antioxidant and androgenic properties of phenols,flavonoids.saponins and sterols revealed in the plant extracts.Objective:To investigate the effects of Dracaena arborea(D.arborea) on the sexual behavior parameters in experienced type-1 diabetic rats.Methods:Aqueous and ethanol(100 and 500mg/kg respectively)extracts of dried root barks of D.arborea.sildenafil citrate(1.44 mg/kg),trimethylamine-N-oxide(TMAO,20 mg/kg)and distilled water(110 mL/kg.were orally administered to 4 weeks streptozolocin-induced diabetic rats.Mount latency and frequency(ML.MF),intromission latency and frequency(IL,IF) and post-ejaculatory interval(PEI) were measured by ejaculating series during 90 min once a week for 4 weeks.Glycemia was determined at the beginning and at the end of the treatment Results:D.arborea did not show any major antihvperglycemic effects.Compared to the control group,a significant(P&lt;0.05-0.001)increase in MF and IF was noticed in rats treated with sildenafil citrate(89.71% and 90.07% respectively),aqueous(500 mg/kg.88.08%and 88.749;respectively) and ethanol(100 mg/kg;89.53%and 89.17respectively) extracts of D.arborea after two weeks(series 1) of treatment.ML,IL and PEI were significantly(P&lt;0.05-0.001) decreased after 4 weeks of daily treatment[sildenafil citrate(96.31.96.31%and 34.98%),and D.arborea aqueous 500 mg/kg(94.33.94.33% and 66.609;i and ethanol extracts 100 mg/kg(96.98.97.089;and 64.26%)].Conclusions:These aphrodisiac potentials of D.arborea in experienced diabetic rats could be due to the antioxidant and androgenic properties of phenols,flavonoids.saponins and sterols revealed in the plant extracts.
