The composition and concentration of hydrophilic extractives in Picea abies needles were studied. The optimal time for harvesting of spruce needles for shikimic acid production was evaluated. The concentration of shikimic acid was ranging from 4.7 mg/g of spruce needles harvested in August to 94.7 mg/g of spruce needles harvested in November.
