Abstract:

Cladonia cornuta (L.) Hoffm harvested from Xinjiang’s Tianshan No.1 glacier was used as the experimental material to extract usnic acid and determine its antioxidant activity and antibacterial activity. Results indicated that the usnic acid extracted from Cladonia cornuta (L.) had higher reducing power and antioxidant capacity. Meanwhile, usnic acid exhibited a significant inhibition on the growth of bacteria such as Proteusbacillus vulgaris, Escherichia coli, Staphylococcus aureus and Bacillus subtilis.

Key words: Cladonia cornuta (L.), usnic acid, antioxidant, antibacterial
