Recent research shows variations in pollen chemical constituents and, consequently, in their therapeutic properties. Mono and multifloral bee pollen extracts were investigated for antioxidant and enzyme inhibitory activity properties, phenolic compounds and fatty acid composition. Generally, spp. and multifloral extracts exhibited potent inhibitory activity against α-amylase, acetylcholinesterase, tyrosinase, lipoxygenase, lipase and hyaluronidase. On the other hand, spp. demonstrated higher antihemolytic activity. and spp. extracts exhibited important antioxidant properties in the different assays (ABTS, DPPH, β-carotene/linoleic acid and reducing power). Moreover, these extracts had greater amounts of total phenols and flavonoids in comparison to others. The increase in antioxidant activity (decrease in EC values) was accompanied by an increase in the amount of total phenols in the extracts. The pollen extracts contained linoleic acid and α-linolenic acid as major fatty acids, followed by palmitic acid, and oleic acid. In this study, differences were observed in both chemical constituents and biological activities of the samples related to the geographical and botanical origin of bee pollen.
最近的研究表明花粉化学成分存在差异，因此其治疗特性也有所不同。对单花和多花蜂花粉提取物的抗氧化和酶抑制活性、酚类化合物和脂肪酸组成进行了研究。一般来说，[具体植物种名]属植物和多花提取物对α-淀粉酶、乙酰胆碱酯酶、酪氨酸酶、脂氧合酶、脂肪酶和透明质酸酶表现出强大的抑制活性。另一方面，[具体植物种名]属植物表现出更高的抗溶血活性。[具体植物种名]属植物和[具体植物种名]属植物提取物在不同的测定方法（ABTS、DPPH、β-胡萝卜素/亚油酸和还原能力）中表现出重要的抗氧化特性。此外，与其他提取物相比，这些提取物含有更多的总酚和黄酮类化合物。提取物中抗氧化活性的增加（EC值降低）伴随着总酚含量的增加。花粉提取物中主要脂肪酸为亚油酸和α-亚麻酸，其次是棕榈酸和油酸。在这项研究中，观察到与蜂花粉的地理和植物来源相关的样品在化学成分和生物活性方面存在差异。
