“…As a result of phytochemical investigations, the presence of the following compounds in the herb of P. anserina was established: catechins (catechin, gallocatechin [6], epigallocatechin, epicatechin, ellagic acid [7]); ellagitannins (agrimoniin, pedunculagin [8]); phenolic acids (gallic, p -hydroxybenzoic, vanillic, gentizic, p -hydroxyphenylacetic, p -coumaric, caffeic, ferulic [9], chlorogenic acids [10]); coumarins (umbelliferon, scopoletin [11]); flavonoids (myricetin [12], myricetin-3- O -β- d -glucuronide, myricitrin, isorhamnetin-3- O -β- d -glucuronide, isoquercitrin, reynoutrin, quercitrin, quercetin-3- O -β- d -sambubioside, miquelianin, astragalin, tiliroside, 8-methoxykaempferol-3- O -sophoroside [6], rutin, nicotoflorin, linarin [10]); isoflavones (genistein [10]); pyrones (2-pyrone-4,6-dicarboxylic acid [13]); aliphatic compounds (nonacosane, ceryl alcohol, arachidic, cerotic, palmitic, myristic, linoleic, linolenic and oleic acids [14]); and polysaccharides [15]. According to known data about the chemical constituents of P. anserina , the occurrence of different classes of phenolic compounds was previously reported for plant material collected in Europe (Poland, Germany, Italy, Ukraine) [6,7,8,9,10,11,12,13].…”
