This study was performed to determine the component analysis and measurements of antioxidant activities from natural seasoning containing Lentinus edodes powder (NSLP) in order to detect the biological activities and develop novel functional resources. It was extracted with 70% ethanol and then further fractionated to hexane, chloroform, ethyl acetate, butanol and water. Methods used in this experiment were measured to examine total polyphenol contents and total flavonoid contents, reducing power and Superoxide dismutase-like activity. Composition analysis were highly composed of carbohydrate as 44.1%. The minerals of different organics were highly composed of sodium as 5,073 mg/100g. There were seventeen total amino acids in NSLP. The glutamic acid content was high up to 16.9 mg/g and aspartic acid, lysine, leucine, alanine were followed. Predominant fatty acid was linoleic acid (62.7%) in NSLP. Contents of total polyphenols in butanol fraction from NSLP were 16.38 mg/100mL. While overall butanol fraction have higher reducing power than ethanol extract, after the addition of 400 μg/mL butanol fraction, auto oxidation of pyrogallol decreased to 83.62% as a result of superoxide dismutase-like activity. A positive correlation was observed between total polyphenol, flavonoid and antioxidant activities.
