Honeybee collected pollen exhibits high nutritional and pharmaceutical benefits for the human diet and medicine. Pollen's antioxidant, anti-ageing, anti-inflammatory, anti-atherosclerosis, and cardioprotective activity, depending on the floral origin, are well known. Recent studies proposed that pollen may also be an excellent cancer-fighting candidate, as pollen harbours high amounts of phenolic substances. In our study, Filipendula ulmaria pollen (bee collected) was methanol-water extracted

... d used to verify its in vitro pharmacological activities on C26 mice cancer tumour cells. Three different concentrations of the extract were tested in antitumour assays. Monitoring was done after 6, 12, 24, and 48 hours. Promising results were obtained for antiproliferative and apoptotic activity of the pollen extracts, with high efficiency for the highest concentration (1 mg/mL). For both activities, time and concentration-dependent effects were observed. Pollen extracts or bee collected pollen has a high potential as an antitumour agent for use in human medicine, because they are both rich in bioactive compounds.
