GC/MS was used as a tool to achieve the chemical profiling of n-hexane extracts from flowers, leaves and stems of plant species Eryngium glaziovianum L. (Apiaceae), an ornamental plant commonly found in several states of Brazil. Gas chromatograms and mass... see more

Here, we assume the construction of cyclic codes over R={F}_{2}[u,v]/ < u^2, v^2 - v, uv - vu >. In particular, dual cyclic codes over R= {F}_{2}[u]/ <u^2> with respect to Euclidean inner product are discussed. The cyclic dual codes ... see more

The chemical constituents and antioxidant activity of the crude extracts of Mentha spicata were investigated. Phytochemical analysis indicated the presence of sugar, flavonoids and alkaloids in the crude extracts of Mentha spicata. GC-TOFMS (Gas Chromatog... see more
