description

Tēja jau vēsturiski lietota, lai veicinātu labu veselību, un vieni no galvenajiem veselību veicinošiem komponentiem tējās ir flavonoīdi. Flavonoīdi ir nozīmīgi augiem, regulējot to attīstību un pildot antioksidantu funkcijas, kā arī tiem ir terapeitiska nozīme cilvēku organismā, veicinot smadzeņu darbības aktivitāti un pildot antioksidantu funkcijas. Kumelītes ir vieni no cilvēcei senāk zināmajiem medicīniskajiem augiem, un ir viena no visvairāk lietotajām viena-auga zāļu tējām, tēpēc ir svarīgi novērtēt šo tēju kvalitāti. Šī darba mērķis ir novērtēt Latvijas veikalos un aptiekās nopērkamo kumelīšu tēju kvalitāti atkarībā no to flavonoīdu daudzuma, un salīdzināt flavonoīdu daudzumu tējām, kas fasētas maisiņos, un beramajām tējām. Lai noteiktu flavonoīdu daudzumu, tiks izmantota alumīnija hlorīda metode un tējas ekstrakta šķīdumu spektrofotometriska analīze pie 415nm gaismas viļņu garuma. Atslēgvārdi: Spektrofotometrs, flavonoīdi, tēja, kumelītes.
