In this study, to confirm the physiological activity of the grasshopper (Oxya chinensis sinuosa) antioxidant activity, antimicrobial activity, thermal stability of the antimicrobial substance, pH stability, total polyphenol content of the adult grasshopper was measured. Antibacterial activity in accordance with the extraction solvent showed a strong antibacterial activity in a mixed solvent of ethanol for the E. coli strain. Antimicrobial activity in hot air drying and a freezedried condition was the highest and there was no difference in the gender. Antibacterial substance was stable to heat and pH. Antioxidant activity of the grasshopper exhibited a high activity in the 50% and 70% ethanol extract. Total polyphenol content was the 12 ~17 mg / 100 g and there was not great difference according to the drying conditions and gender.
