title: Effect of essential oil of traditional two Saudi mint types and its possible role in cardiovascular and throat health.
abstract: Essential Oil (EO) of two Mentha species (popularly used in Saudi Arabia), Mentha Longifolia (ML), and Mentha pulegium (MP) was isolated and subjected to inhibit LDL oxidation in 22 hypercholestrolemic samples collected from 22 subjects, and inhibited of 5 bacterial pathogen in vitro. LDL was isolated by ultracentrifugation and enhanced to oxidation with CuSO4 and EO was added to prevent this oxidation, free radical scavenging activity was measured (decrease 50% DPPH radicals). EO content of phenolic and flavonoid was estimated. Five bacterial strains infect human throat was tested against EO of ML and MP in diffusion agar method. EO of the two herbals possess highly significantresults, success to inhibit LDL oxidation (P<0.001 for both herbal than non addition against lipid peroxidase, P<0.001 ML better than MP P<0.001), decreased DPPH free radicals (P<0.001 for both than control, P<0.001 for ML than MP), and possess strong antioxidant activity for ML than MP (polyphenol and flavonoids contents was higher in EO of ML than MP, P<0.001). EO of ML possess strong antioxidant and antibacterial activity than MP, these attributed to its high flavonoid contents enable it to be a good for cardiovascular and throat health. The study supported the traditional uses of ML.
