Abstract:

The contents of proteins and amino acids of Helianthus annuus, Schisandra chinensis, Leonurus heterophyllus
bee pollens were determined. Based on the analysis data obtained in this study and those reported in literature for bee pollens
from Helianthus annuus and Schisandra chinensis as well as 10 other plant species, comprehensive evaluation of protein
nutrition was carried out using internationally recognized methods with respect to protein content, chemical score (CS),
essential amino acid index (EAAI), score of ratio coefficient of amino acids (SRCAA), biological value (BV) and nutritional
index (NI). The results indicated that these values for 13 bee pollens were 14.3%—29.0%, 64.4—89.3, 66.9—107, 0, 79.9—91.1,
61.2—104.9 and 11.7—29.3, respectively. The protein content, CS, EAAI, SRCAA, BV and NI for Camellia japonica bee
pollen were 29.0, 83.1, 101.3, 88.8, 98.7 and 29.3, respectively, which were all higher than the average levels of these 13 bee
pollens and indicated the most balanced nutrition.
