Chemical components such as vitamins, fatty acids, amino acids and rutins in the leaves of the Pinus densiflora Sieb. et Zucc., Pinus koraiensis Sieb. et Zucc., Pinus rigida Mill., Pinus thunbergii Parl. were analyzed. The vitamin A content in the P. densiflora and vitamin C content in the P. thunbergii were obtained more than the others. Oleic acid, linolenic acid, palmitic acid and lauric acid were the major fatty acids among 19 fatty acids betected in 4 kinds of pinus leaves and the only essential fatty acid of linolenic acid was also identified. the major amino acids were glutamic acid, leucine, arginine and aspartic acid among 17 kinds of amino acids betected in the pinus leaves and the amount of essential amino acids was 47.6% in P. densiflora. The highest amount of rutin was 10.34% in P. thunbergii.
