Abstract

This study was to analyze the chemical components of the pollens of Pinus densiflora S. et Z. and P. thunbergii Parl. and to investigate the optimal conditions for pollen pulverization. The results were as follow : (1) The contents of moisture, crude ash, crude protein, crude fat, crude filber and carbohydrate in the pollen of P. densiflora were 9.8%, 2.3%, 11.9%, 2.9%, 7.7%, and 65.4%, respectively, while those of P. thunbergii were 10.5%, 2.2%, 13.5%, 3.5%, 8.5% and 61.8%, respectively. All the contents of P. densiflora and P.thunbergii were much higher than those general crop grains. (2) The pollen of Pinus densiflora and P. thunbergii eighteen different amino acids were detected in. Among them, ten esssential amino acids were identified, which showed high nutrition values. (3) The contents of vitamins A, B1, B2, C and E in the pollen of P. densiflora were 7.9mg, 8.7mg, 19.2mg, 31.5mg and 2.0mg, respectively, while those in the pollen of P. thunbergii were 8.5mg, 9.4mg, 15.7mg, 35.3mg, and 1.8mg respectively. Vitamin C among them was abundant. (4) When the pollen grains of P. densiflora were pilverized for 40 minutes at 5,000rpm and P. thunbergii, for 50 minutes at 5,000rpm by overhead stirrer, the 100% of pollen pulverization was possible.
