Study Findings
• Antioxidant: Study showed that parsley oil possessed a certain degree of antioxidant activities in terms of ß-carotene bleaching and free radical scavenging, with negligible metal chelating capacity. Myristicin was found to be the dominant compound that exhibited a moderate antioxidant activity. Results showed PO can be a potential alternative source of natural antioxidants.
• Hepatoprotective: Study showed that parsley has a significant hepatoprotective effect in diabetic rats.
• Antibacterial: Study of P crispum extract showed inhibitory effect at various concentrations against Gram-positive and Gram-negative bacteria. It showed inhibitory effect against Br melitensis, E coli and B lichiniformis. Results confirm its use in folk medicine.
• Diuretic / Hypotensive: Study of the aqueous extracts of parsley seeds showed diuretic and hypotensive effects in anesthetized Wistar rats, confirming its traditional use in Brazil as a herbal diuretic.
