Two New Enzymes of Rosmarinic Acid Biosynthesis from Cell Cultures of Coleus blumei: Hydroxyphenylpyruvate Reductase and Rosmarinic Acid Synthase
Rosmarinic acid biosynthesis can be stimulated in cell cultures of Coleus blumei by culturing the cells in medium with 4% sucrose. In enzyme extracts of these cells two new enzymes of rosmarinic acid biosynthesis were discovered. Hydroxyphenylpyruvate reductase reduces 4-hydroxyphenylpyruvate and 3,4-dihydroxyphenylpyruvate to 4-hydroxyphenyllactate and 3,4-dihydroxyphenyllactate, respectively,...
متن کاملRegulation of lithospermic acid B and shikonin production in Lithospermum erythrorhizon cell suspension cultures.
Cell suspension cultures of Lithospermum erythrorhizon produced a large amount of lithospermic acid B, a caffeic acid tetramer, as well as shikonin derivatives (each ca. 10% of dry wt.) when cultured in shikonin production medium M-9. Various culture factors for increasing the production of lithospermic acid B were investigated. Lithospermic acid B production was inhibited by 2, 4-D or NH4+, wh...
متن کاملProduction of Rosmarinic Acid in Echium amoenum Fisch. and C.A. Mey. Cell Cultures
Echium amoenum Fisch. and C.A. Mey. (Boraginaceae) is a very popular medicinal plant which is used as a tonic, tranquillizer, diaphoretic, cough remedy, sore throat and pneumonia in Iran’s traditional medicine. Callus culture of medicinal plants is one of the ways for production of secondary metabolites. In this study, callus culture of E. amoenum and its major secondary metabolite were investi...

متن کاملSelenium enhances nutrient uptake and rosmarinic acid biosynthesis in Melissa officinalis L. under salinity stress
Salt stress is a serious problem facing plant growth and development. Selenium (Se) could improve plant growth and reduced stress. Hence, the aim of this study was to determine whether the Se application could alleviate salinity stress negative effects on Melissa officinalis L. Different salinity levels in this research were control (0), 50, 100 and 200 mM. Simultaneously, sodium selenate (Se) ...
