This study identified flavonoid glycosides in species of the genus Alchemilla, A. procerrima, A. stricta, A. hirtipedicellata and A. sericata. A. procerrima is an endemic species for Turkey. After detailed investigation, flavonoid compounds of the species were identified for the first time. In this study, flavonoid compounds were determined by using two different chromatography techniques, TLC and HPLC. The following flavonoid compounds were identified from the Alchemilla species studied. They are as follows: orientin ( were also identified for the first time in this study. Rutin (quercetin-3-O-rutinoside) and the flavonoid glycoside, shown as Rf 2 were found in all species. Quercitrin and isoquercetin were determined in all analysed species but A. procerrima. Hyperoside was identified in all species except for A. stricta. Vitexin was determined only in A.stricta. Orientin was determined in A. procerrima and A. stricta, but could not be determined in A. sericata and A. hirtpedicellata. Unknown flavonoid with Rf 1 and Rf 3 were determined outside of A. sericata. Description of these compounds in Turkish Alchemilla plants for the first time should be viewed as a discovery of an important chemosystematic feature.

Due to their distinct characteristics and possible uses in a variety of disciplines, nanoparticles have attracted a lot of attention recently. One area of interest is the synthesis of nanoparticles using natural sources such as bee pollen. The research aims to evaluate the usability of bee pollen extract‐based magnesium nanoparticles (MgNPs). First, a palynological study was used to determine the plant source of bee pollen. The nanoparticle was characterized using scanning electron microscopy, energy dispersive X‐ray analysis, transmission electron microscopy, X‐ray diffractometry, and Fourier transform infrared spectroscopy. The results revealed cubic‐shaped MgNPs with an average size range of 36–40 nm. Afterward, nanoparticles were evaluated for their antioxidant, antimicrobial, and neurotoxic properties. It was determined that the total antioxidant capacity, phenolic (TPC), flavonoid (TFC) content, DPPH radical scavenging, and antimicrobial activity of the nanoparticles were lower than pollen extract. At the same time, nanoparticles have less toxicity than bee pollen.
