بررسی تنوع در ژنوتیپهای سه گونه نعناع ( .Mentha piperita L.، M. aquatica L و M.spicata L ) در واکنش به شوری

Chrysolina herbacea Modulates Terpenoid Biosynthesis of Mentha aquatica L.

Interactions between herbivorous insects and plants storing terpenoids are poorly understood. This study describes the ability of Chrysolina herbacea to use volatiles emitted by undamaged Mentha aquatica plants as attractants and the plant's response to herbivory, which involves the production of deterrent molecules. Emitted plant volatiles were analyzed by GC-MS. The insect's response to plant...

تغییرات بیوشمیایی نعناع فلفلی (Mentha piperita L.) در شرایط خشکی

تولید گیاهان دارویی مانند نعناعیان بطور چشمگیری در جهان در حال افزایش است. یکی از گیاهان مهم این خانواده، نعناع فلفلی (Mentha piperita L.) است. اهمیت آن بدلیل ترکیب منتول در اسانس آن است. در این پژوهش، پاسخ های فیزیولوژیک و بیوشیمایی نعناع فلفلی در سطوح مختلف آبیاری شامل: نرمال، 75، 50 و 25 درصد ظرفیت زراعی (FC) در قالب طرح کاملا تصادفی با سه تکرار در گلخانه تحقیقاتی گروه زراعت و اصلاح نباتات د...

Study on essential oil of Mentha aquatica L. from Vietnam++++++

The characterization of essential oils of Mentha aquatica L grown in two Provinces of Vietnam was performed by means of gas chromatography-flame ionization detector (GC-FID) and gas chromatography-mass spectrometry (GC-MS) techniques. The major constituents of the essential oils were epi-bicyclosesquiphellandrene (58.9% and 52.4% respectively) and limonene (21.1% and 31.4% respectively) for Tha...

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...

Assessment Report on Mentha X Piperita L., Folium

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...
