Metabolism of Monoterpenes : EVIDENCE FOR COMPARTMENTATION OF l-MENTHONE METABOLISM IN PEPPERMINT (MENTHA PIPERITA) LEAVES.
Previous studies have shown that the monoterpene ketone l-[G-(3)H]-menthone is reduced to the epimeric alcohols l-menthol and d-neomenthol in leaf discs of flowering peppermint (Mentha piperita L.), and that a portion of the menthol is converted to menthyl acetate while the bulk of the neomenthol is transformed to neomenthyl-beta-d-glucoside (Croteau, Martinkus 1979 Plant Physiol 64: 169-175). ...
متن کاملMetabolism of Monoterpenes: Conversion of l-Menthone to l-Menthol and d-Neomenthol by Stereospecific Dehydrogenases from Peppermint (Mentha piperita) Leaves.
The monoterpene ketone l-menthone is specifically converted to l-menthol and l-menthyl acetate and to d-neomenthol and d-neomenthyl-beta-d-glucoside in mature peppermint (Mentha piperita L. cv. Black Mitcham) leaves. The selectivity of product formation results from compartmentation of the menthol dehydrogenase with the acetyl transferase and that of the neomenthol dehydrogenase with the glucos...
متن کاملPerformance 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...
متن کاملAllometric Ratio of Menthol and Menthone to Pulegone in the Essential Oil of Peppermint (Mentha piperita L.) Affected by Bioregulators
Background and objectives: Menthol and menthone are two important components in the essential oil of peppermint(Mentha piperita L.) which are commercially used in the pharmaceutical industries. This study has presented the allometric ratio of menthol and menthone to pulegone affected by the induction of bioregulators. Methods: The experiment w...
متن کاملEnvironmental 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...
