An experimental steam distillation unit has been designed, built, and tested for the extraction of essential oils from peppermint and spearmint. The unit, using a 130-gal (510-liter) distillation tank, is intermediate in size between laboratoryscale extractors and commercial-sized distilleries, yet provides oil in sufficient quantity for industrial evaluation. The entire apparatus-a dieselfuel-...

background & aim:peppermint known for its healing properties is a plant from the labiatae family. currently, different rates of nitrogenous fertilizers are used in production of peppermint while there is no precise information available about how much of nitrogen fertilizer is the optimum rate for this plant. the main purpose of this research was to evaluate the response of peppermint chemical ...

introduction: colonoscopy is an invasive method that is painful for patient especially for children. the objective of this research was investigation into the effect of supermint oral drop (peppermint essence) on the patient and colonoscopist group satisfaction during colonoscopy.   material and methods: in this clinical trial study, 101 children candidate colonoscopy (7-14 years old) in childr...

In a literature search 16 clinical trials investigating 180-200 mg enteric-coated peppermint oil (PO) in irritable bowel syndrome (IBS) or recurrent abdominal pain in children (1 study) with 651 patients enrolled were identified. Nine out of 16 studies were randomized double blind cross over trials with (n = 5) or without (n = 4) run in and/or wash out periods, five had a randomized double blin...

Changes in essential oil composition of peppermint (Mentha x piperita L.) affected by yeast extract and salicylic acid foliar application

This study evaluated the effects of inoculation with the arbuscular mycorrhizal fungi Glomus mosseae, Glomus intraradices A4 and Glomus intraradices B1 and two phosphorus levels (10 and 40 mg kg-1) on root colonization, plant growth, nutrient uptake and essential oil content in Mentha piperita L. The experiment was carried out in a greenhouse, in 4x2 factorial arrangement, in completely randomi...

background: mentha piperita l. essential oils have different antibacterial activity. in the present study, we investigated the effect of γ–irradiation on the antibacterial activities of mentha piperita l. essential oils in vitro and in vivo systems. materials and methods: the aerial parts of peppermint were irradiated in a cobalt60 source with 0, 10 and 25 kgy absorbed doses. then, the plants w...
