anglais. With the purpose to assess potential of alder tree bark as a renewable source of bioactive polyphenolic compounds, antioxidant properties of hydrophilic extracts and proanthocyanidins (PAC) isolated from bark of two alder species (grey alder and black alder) growing in Latvia have been examined employing two test systems, ABTS ●+ , DPPH ● assays. In the tests the high free radical scavenging capacities of the PAC were demonstrated. The polyphenolic nature of the bark PAC opens the possibility of its application as food additive. The PAC has good potential as an antioxidant for mayonnaise.

letton. Latvijā augošā alkšņu miza ir perspektīva izejviela proantocianidīnu un ar tiem bagātināto ekstraktu iegūšanai biorafinēšanas kontekstā. Eksperimentālie pētījumi (testi ar DFPH • un ABTS + • radikāļiem) parādīja proantocianidīnu no baltalkšņa un melnalkšņa mizas augsto antioksidatīvo aktivitāti, kas paplašina proantocianidīnu izmantošanas iespējas. Vislielāko antioksidatīvo aktivitāti parādīja PAC no melnalkšņa mizas. Tika izpētīta PAC antioksidatīvā darbība lipīdu saturošās sistēmās, kā arī novērtēts to izmantošanas potenciāls veselības aprūpes nolūkā.
