„In Tibetan medicine, P. anserina herb is used for infectious diarrhea with fever, while its roots and rhizomes are applied as an antiseptic remedy. In Yakutian medicine, the tincture from P. anserina flowers in vodka is used as an antidiarrheal remedy; the water decoction from flowers and leaves is applied for kidney and liver diseases, respectively. The gruel from the fresh leaves is used as a wound-healing agent. In Chinese medicine, the whole plant is applied for the treatment of hematemesis. Traditionally, Mongolian arats (cattle-breeders) applied P. anserina as an astringent and bactericidal remedy for treatment of enterocolitis and dyspepsia…
As a result of phytochemical investigations, the presence of the following compounds in the herb of P. anserina was established: catechins (catechin, gallocatechin, epigallocatechin, epicatechin, ellagic acid); ellagitannins (agrimoniin, pedunculagin); phenolic acids (gallic, p-hydroxybenzoic, vanillic, gentizic, p-hydroxyphenylacetic, p-coumaric, caffeic, ferulic, chlorogenic acids); coumarins (umbelliferon, scopoletin); flavonoids (myricetin, 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, rutin, nicotoflorin, linarin); isoflavones (genistein); pyrones (2-pyrone-4,6-dicarboxylic acid); aliphatic compounds (nonacosane, ceryl alcohol, arachidic, cerotic, palmitic, myristic, linoleic, linolenic and oleic acids); and polysaccharides.
The dry extract of P. anserina herb was the most enriched formulation containing 16.18% of total phenolics, including 8.41% of agrimoniin, 4.65% of flavonoids, 1.36% of caffeic acid, and 1.76% of ellagic acid.“
