  Weigh 5.0 g of chopped Usnea longiflora into a 500 mL flask, and extract with 75 mL of ethyl acetate for 2 times, 4 h each time, and combine the extracts. Suction filtration, concentrated to 1/6~1/8 of the original volume, naturally cooled, crystallized, filtered off the mother liquor, and dried at 80°C to obtain the crude usnic acid. 30 times the amount of benzene-ethanol (volume ratio 1:1) mixed solvent was added to the crude product, refluxed for 2 h, filtered while hot, the filtrate was concentrated to 1/5 of the original volume, and crystals were precipitated by cooling. Dry at 80 ℃, recrystallize twice with ethyl acetate, and the obtained relatively pure pale yellow needle crystal is the fine usnic acid.
