内容記述 | The lichens are symbiotic organisms, synthesize a great variety of chemically complex. Natural and potential source of bioactive compounds. U. antarctica and U. aurantiaco-atra were collected during 23rd Peruvian Scientific Expedition (ANTAR XXIII–2015) from the Antarctic Scientific Station “Machu Picchu” and were transferred to the ITP for processing. The samples were dried and grounded, after that, an extraction with acetone (1:10 w/v) also with methanol (1:10 w/v) was performed. Both extracts were mixed and vacuumed dried (30 °C). A methanol-acetone extract (MAE) from each lichen was obtained. MAE from U. antarctica showed a major concentration of total phenols (22.80 ± 0.08 mg GA/g MAE) than U. aurantiaco-atra (19.42 ± 0.32 mg GA/g MAE). Besides, U. antarctica exhibited a superior value of inhibition of ABTS•+ radical (89.05 ± 0.01 μmol TE/g MAE) than U. aurantiaco-atra (79.84 ± 0.09 μmol TE/g MAE).
