Influence of Methyl Jasmonate on Menthol Production and Gene Expression in Peppermint (Mentha x piperita L.)

Peppermint has considerable commercial value and widely cultivated for essential oil production, especially menthol. The aim of this study was to determine the quantitative expression of pulegone reductase (pr), menthofuran synthase (mfs) and limonene synthase (ls) genes in menthol biosynthesis pathway in Mentha x piperita , using semiquantitative RT-PCR analysis and evaluating menthol producti...

Effect of Simulated Acid Rain on Chlorophyll and Ascorbic Acid Contents of Mentha Piperita L.(peppermint)

A field and laboratory based experiment conducted to assess the effects of different pH ranges of simulated acid rain (2.5, 3.5, 4.5 and 5.5) was studied on chlorophyll and ascorbic acid contents in two cultivars (cv. Himalaya and cv.Kaushik) of a medicinal herb Mentha piperita. Chlorophyll and ascorbic acid contents of leaves were adversely affected at pH 2.5 and 3.5. The effects of simulated ...

Environmental Factors Affecting the Accumulation of Rosmarinic Acid in Spearmint (Mentha spicata L.) and Peppermint (Mentha piperita L.)

Four spearmint, and two peppermint clonal lines, selected for enhanced rosmarinic acid content (50-120 mg g -1 rosmarinic acid DW), where up to 80% of the antioxidant activity was correlated to rosmarinic acid content, were examined to determine the effects of environmental and physiological conditions on the accumulation of rosmarinic acid in leaf tissues. Exposure to a short photoperiod of 12...

Performance of Broilers Supplemented With Peppermint (Mentha piperita L.) Powder

This study was conducted to determine the effects of dietary supplementation of peppermint ( Mentha piperita L.) on the performance of broiler chicks. 500 Ross broiler chicks were divided into 5 treatment groups of 4 replications in a completely randomized design format. The diets were ISO-caloric and ISO-nitrogenous ones and contained 1.5, 3, 4.5, and 6 g/kg of peppermint powder. At start, gro...
