Abstract:
Objective: To analyse the chemical composition of essential oil isolated from the leaves ofToddalia asiatica (L.) Lam. and to test its bioactive properties. Methods: Gas chromatography-mass spectrometry (GC/MS) analysis and antigenotoxicity, cytotoxicity and antioxidant studies of isolated oil. Results: GC-MS analysis of oil revealed the presence of 42 compounds. The major compound in the oil was β-phellandrene (21.35%). DNA protecting activity of oil was considerably significant against H2O2 induced genotoxicity in human lymphocytes. Concentration of oil needed to protect 50% of DNA was calculated as 100 μg/mL. Cytotoxicity of oil against breast (MCF-7) and colorectal (HT-29) cancer cells were observed with the IC50 value of (7.80±0.03) μg/mL and (100.00±0.16) μg/mL respectively. Considerable DPPH free radical, hydroxyl radical scavenging, iron chelation and inhibition of lipid peroxidation activities of oil were also studied. Conclusions: The results of the present study clearly indicate oil could be a promising candidate for food and drug preparation.
