Abstract


This study sought to investigate the effect of β-caryophyllene (BCP) on sexual performance, crucial enzymes linked to erectile function as well as lipid peroxidation in the penile tissue of paroxetine (PD)-induced rats. Animals were randomly divided into ten groups of five animals each: normal control (NC), BCP (10 mg/kg), BCP (20 mg/kg), sildenafil citrate (SD) (20 mg/kg), BCP?+?SD (20 mg/kg), PD (20 mg/kg), PD?+?BCP (10 mg/kg), PD?+?BCP (20 mg/kg), PD?+?SD (20 mg/kg) and PD?+?BCP (20 mg/kg)?+?SD (20 mg/kg). Oral administration of 20 mg/kg body weight of PD for the first 7 days was done while treatment with BCP and SD were performed between 8 and 14 days prior to euthanasia. The sexual performance study revealed that PD caused erectile dysfuction. Elevated activities of phosphodiesterase-5′ (PDE-5′), arginase, adenosine deaminase (ADA), acetylcholinesterase (AChE) and angiotensin-I converting enzyme (ACE) as well as lipid peroxidation level were observed in PD-induced rats when compared to the NC group. However, treatment with sildenafil and/ or β-Caryophyllene significantly reduced the activities of AChE, PDE-5′, arginase, ADA, and ACE in penile tissues of PD-induced rats. In addition, co-administration of β-caryophyllene and sildenafil citrate showed better modulatory effects. Thus, β-caryophyllene could represent a potential nutraceutical in the management of erectile dysfunction.
