Palynological spectrum, proximate and fatty acid (FA) composition of eight bee bread samples of different botanical origins were examined and significant variations were observed. The samples were all identified as monofloral, namely (94.4%), spp. (85.6%), (66.2%), spp. (61.4%) and (45.4%). Each had moisture content between 11.4 and 15.9%, ash between 1.9 and 2.54%, fat between 5.9 and 11.5%, and protein between 14.8 and 24.3%. A total of 37 FAs were determined with most abundant being (9Z,12Z,15Z)-octadeca-9,12,15-trienoic, (9Z,12Z)- -octadeca-9,12-dienoic, hexadecanoic, (Z)-octadec-9-enoic, (Z)-icos-11-enoic and octadecanoic acids. Among all, cotton bee bread contained the highest level of ω-3 FAs, 41.3%. Unsaturated to saturated FA ratio ranged between 1.38 and 2.39, indicating that the bee bread can be a good source of unsaturated FAs.
对八个不同植物来源的蜂粮样本的孢粉学光谱、近似成分和脂肪酸（FA）组成进行了检测，并观察到显著差异。这些样本均被鉴定为单花源，即（94.4%）、 spp.（85.6%）、（66.2%）、 spp.（61.4%）和（45.4%）。每个样本的水分含量在11.4%至15.9%之间，灰分在1.9%至2.54%之间，脂肪在5.9%至11.5%之间，蛋白质在14.8%至24.3%之间。共测定了37种脂肪酸，其中含量最丰富的是（9Z,12Z,15Z）-9,12,15-十八碳三烯酸、（9Z,12Z）- -9,12-十八碳二烯酸、十六烷酸、（Z）-9-十八碳烯酸、（Z）-11-二十碳烯酸和十八烷酸。其中，棉花蜂粮中ω-3脂肪酸的含量最高，为41.3%。不饱和脂肪酸与饱和脂肪酸的比例在1.38至2.39之间，这表明蜂粮可能是不饱和脂肪酸的良好来源。
