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 ...

α-amylase inhibitors are used in the treatment of type II diabetes mellitus. This study aims to identify the α-amylase inhibitors from two medicinal plants Mentha piperita and Annona squamosa. Primarily, the extract of both leaves was prepared using methanol and water and perform the screening of phytochemicals constituents present in the extract. Aqueous and methanol extract of mentha leaves c...

Article history: Received on: 25/12/2013 Revised on: 08/02/2014 Accepted on: 23/05/2014 Available online: 28/06/2014 The effect of tissue cultured and tissue culture derived Mentha species viz. Mentha piperita(PPR611), Mentha arvensis (SH) and Mentha spicata (SPR 8) on antioxidant potential using lipid peroxidation model was studied. The extracts prepared were analyzed for total phenols and fla...

The p-menthane monoterpenes of the Mentha species are biosynthesized from geranyl pyrophosphate via the monocyclic olefin 4S-limonene. A monoterpene cyclase was isolated from both Mentha x piperita (peppermint) and Mentha spicata (spearmint) that catalyzes the cyclization of geranyl pyrophosphate to 4S-limonene. This enzyme, 4S-limonene synthase, was purified to apparent homogeneity by dye liga...

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...
