摘要：Mentha ecotypes from diverse geographic regions show different chemical composition of important secondary metabolites. The objective of this study was to evaluate the chemical composition of indigenous mint (Mentha) germplasm collected from Azad Kashmir Rawalakot. Three varieties of mint Mentha piperita, Mentha longifolia and Mentha arvensis were collected from different sites of Rawalakot. These genotypes were analyzed for important biochemical parameters like total soluble solids, pH of juice, total moisture content, dry matter, vitamin C, oil content, total phenolic content, Phosphomolybdenum and antioxidant assays. The response to different traits varies with type of plant species and at different geographic location, and its mean values ranged for total soluble solids (0.72-0.488 mg/g), pH of the juice (6.60-6.45), total moisture content (87.67-71%), dry matter (34.67-14.00 %), vitamin C (22.48-21.01mg/100g), oil content (173.6-11.77%), total phenolic contents (214.2-173.6mg/g), Phospho molybdenum assay free scavenging activity (22.53-19.60µg/ml) and the total antioxidant activity by DPPH radical scavenging (>65-50%). In present study, it was concluded that mint species which are grown in this Rawala- kot had great approaching in term of medicinal and genetic traits. These species were also rich in phenolic and antioxidant activities. The Merntha arvensis showed high concentration of phenolic and antioxidant activities due to favourable environment conditions which prevail in Rawalakot.
