Exudates (DE) secreted from two shiitake mushroom mycelia (strains 1358 and L5458) were evaluated for their antioxidative properties and phenolic content. 1358DE and L5458DE showed distinct antioxidant activity in different in vitro assays, including scavenging activity on 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals, hydroxyl radical, superoxide anions and hydrogen peroxide; the ability to chelate ferrous ions; reducing power; hemolysis inhibition activity in rat erythrocyte; and lipid peroxidation inhibition (IC50 values of 1358DE and L5458DE were 3.3 and 132.6; 44.5 and > 1000; 26.9 and 53.7; 153.6 and >175.0; 176.0 and 521.0; 26.7 and 746.4; 47.8 and 736.9; and 3.1 and > 1000 μg/mL, respectively). Their total phenolic content was 237.33 and 24.08 mg gallic acid equivalent (GAE)/g of dry DE, respectively. Overall, these results show that 1358DE generally possesses better antioxidant properties than L5458DE, possibly due to its larger total phenolic content. Shiitake mushroom mycelial exudates, particularly of 1358DE, could be a good source of natural antioxidants.

The bioactive compounds, as well as the in vitro antioxidant activity of two Savoy cabbage cultivars, Dama and Leticia, grown in west of Spain under similar conditions were identified, quantified and compared. We found that cv. Dama presented in general betters results when compared with cv. Leticia. Cv. Dama presented higher concentrations of chlorophyll a (2.26 mg/100 g fresh weight), total phenolic content (102.71 mg of chlorogenic acid equivalent/100 g fresh weight) and total intact glucosinolates (195.22 µmol of sinigrin equivalent/100 g fresh weight). Thus, cv. Dama exhibited higher values of in vitro antioxidant activity.

ABSTRAK Penelitian ini bertujuan untuk menentukan kandungan total fenolik dan aktivitas antioksidan ekstrak etanol dan n-heksana dari daun Artemisia vulgaris L. Total fenolik diukur menggunakan metode Follin-Ciocalteau dengan asam galat sebagai larutan standar. Aktivitas antioksidan diukur berdasarkan analisis kadar peroksida dan malonaldehida (MDA) dari minyak ikan. Hasil penelitian menunjukkan bahwa ekstrak etanol memiliki kandungan total fenolik sebesar 81.22 mg/kg dan ekstrak n-heksana sebesar 20.10 mg/kg. Kemampuan penghambatan peroksida maupun MDA oleh ekstrak etanol lebih tinggi daripada ekstrak n-heksana. Sebagai pembanding, α-tokoferol memiliki aktivitas penghambatan peroksida dan MDA lebih tinggi daripada ekstrak n-heksana, tetapi lebih rendah daripada ekstrak etanol. Kata kunci :Artemisia vulgaris L., antioksidan, fenolik, peroksida, malonaldehida   ANTIOXIDANT ACTIVITY OF THE ETHANOL AND n-HEXANE EXTRACTS OF LEAVES OF GRASS SANTA MARIA (Artemisia vulgaris L.) IN FISH OIL ABSTRACT The purpose of the study was to determine the total phenolic content and antioxidant activity of the ethanol and n-hexane extracts of leaves of Artemisia vulgaris L. Total phenolic was determined using Follin-Ciocalteau method with gallic acid as a standard solution. The antioxidant activity was measured based on the analysis of the levels of peroxide and malonaldehida (MDA) in fish oil. The results showed that the ethanol extract had a total phenolic content of 81.224 mg/kg and n-hexane extracts of 20.101 mg/kg. The ability of peroxide and MDA inhibition by ethanol extract was higher than that by n-hexane extract. For comparison, α-tocopherol has higher inhibitory activity on peroxide and MDA than n-hexane extracts, but lower than ethanol extract. Keywords: Artemisia vulgaris L., antioxidants, phenolic, peroxide, malonaldehida
