“…The exine is mainly composed of sporopollenin to protect the vulnerable plant gametes against a wide range of environmental assaults 36 . Therefore, prior work has suggested that breaking pollen wall can improve the digestibilities and absorptivities 7,12,13 . Nevertheless, some studies have claimed that bee pollen does not need wall‐disruption.…”

“…For example, total phenolic contents, total flavonoid and total antioxidant [2,2‐diphenyl‐1‐picrylhydrazyl (DPPH) and cupric ion antioxidant capacity (CUPRAC)] values were 3.9–9.2 mg gallic acid equivalents (GAE) g –1 , 1.2–1.9 mg catechin equivalents g –1 sample, 1.7–17.6 mg Trolox equivalent antioxidant capacity (TEAC) g –1 and 0.68–3.04 mg TEAC g –1 , respectively. Conversely, the bioaccessible fraction was only 0.24–0.37 mg GAE g –1 for total phenolic, 0.01–0.08 TEAC g –1 for total flavonoid, 0.01–0.38 mg TEAC g –1 for DPPH and 0.01–0.4 mg TEAC g –1 for CUPRAC 12 . Moreover, comparing with the in vitro protein digestibility of oak pollen with 69.5%, kiwi pollen was only 37.8%.…”

BACKGROUND Bee pollen is considered as a treasure trove of human and animal nutrients as a result of its extensive nutritional and therapeutic properties. However, the sophisticated pollen wall can largely limit the digestibility and bioavailability of these nutrients. RESULTS An ultrasonication and high shear technique was used to break the walls of five species of bee pollen, including rape bee pollen, lotus bee pollen, camellia bee pollen, wuweizi bee pollen and apricot bee pollen. We compared the digestibilities of bee pollen with or without wall‐disruption. After in vitro and in vivo digestion, unbroken bee pollen grains were still intact and the fragments of wall‐disrupted bee pollen still remained as fragments. Mouse in vivo digestion results suggested that the wall‐disrupted bee pollen was more easily emptied from the gastrointestinal tract than unbroken bee pollen. After dynamic in vitro digestion, the digestibilities of protein and crude fat in wall‐disrupted bee pollen significantly increased to more than 80%; similarly, the release rates of amino acids and reducing sugars in all wall‐disrupted samples were almost 1.5 and 2 times as much as those of unbroken samples. CONCLUSION Based on the results obtained in the present study, we strongly recommend that bee pollen should be wall‐disrupted. © 2020 Society of Chemical Industry

“…A literature review revealed previous reports on the use of a chemical system to evaluate the antioxidant capacity of pollen extracts (Ozkan et al., ; Qiu et al., ; Saliha & Büşra, ). Dong, Zhang, Li, and Ren () studied the in vitro antioxidant capacity of eight different pollen alcohol extracts and found that the DPPH radical scavenging capacity, total reducing power, and TAC were in the order of canola> rose> buckwheat; the hydroxyl radical scavenging capacity was in the order of canola> buckwheat> rose.…”

The crude flavonoid extract of pollen (CFP) of four species of honeybee pollens were extracted with ethanol, and the total flavonoid contents ranged from 3.4 to 14.5 mg rutin/g dry weight. The antioxidant activities of the CFPs were evaluated from both chemical and cytological aspects. Comprehensive antioxidant scores were determined based on these two evaluation systems. The results showed that canola CFP had the highest antioxidant capacity among the four CFPs. A cytotoxicity assay was conducted to assess the safety threshold of the CFPs, and canola CFP was proved to be the least toxic to vascular endothelial cell. Of the four tested CFPs, this research suggests that canola CFP is the most promising natural antioxidant. In addition, high‐performance liquid chromatography (HPLC) analysis detected seven flavonoid glycosides in the hydrolysates of the four CFPs. Among them, quercetin and kaempferol were present in all four honeybee pollen extracts, but there were significant differences between their contents. A correlation analysis revealed a strong correlation between the content of quercetin in the pollen extract and the extract's antioxidant activity. Practical Application Many varieties of honeybee pollen are commercially available. The results of this study help guide consumers to choose honeybee pollens that have a better antioxidant effect. This report can also provide guidance and data in support of the development of honeybee pollen health products.

Apiterapi arı ve arı ürünlerinin bazı hastalıkların tedavisinde tamamlayıcı ve destekleyici olarak kullanılmasıdır. Bal, polen, propolis, arı sütü, arı zehiri, balmumu ve apilarnil gibi bal arılarından elde edilen doğal ürünler apiterapi ürünlerinden bazılarıdır. Ulusal ve uluslararası pek çok dernek ve apiterapi merkezi bulunmaktadır. Arı ürünleri çok yönlü farmakolojik aktiviteleri sayesinde anti-aging, antienflamatuar, antikarinojenik, antimikrobiyel olmak üzere pek çok etki gösterir. Böylece hipertansiyon, diyabet, kardiyovasküler sistem bozuklukları, kanser, kas iskelet sistemi gibi hastalıkların tedavisinde destekleyici tedavi olarak önerilmektedir. Apiterapi ürünleri birçok hastalıklarda iyi geldiği gibi aynı zamanda obstetri ve jinekoloji alanında da kullanılmaktadır. Kullanımı giderek artan apiterapi ürünlerinin hastalıkları tek başına tedavi edeceği ve hastalığı ortadan kaldıracağı söylenemez. Bu derlemenin amacı; obstetride ve jinekolojide apiterapinin kullanımı konusunda güncel literatür doğrultusunda bilgi vermektir.
