Determination of the metabolic profile of Solidago canadensis using UFLC-PDA-ESI-TOF
Abstract Species in the Solidago genus are used worldwide due to the therapeutic activities of their flavonoids and terpenoids. Its anti-inflammatory, antirheumatic, analgesic, diuretic, aquaretic, wound-healing properties as well as its ability to relieve burn and insect bites allow use in a variety of situations. This study was carried out to determine the metabolic profile of Solidago canadensis inflorescences (SCAI) to identify the species commercialized in Rio de Janeiro, RJ, Brazil, and evaluate the medicinal potential compared to S. chilensis and SCAI, which is used in North America and Europe. The UFLC-PDA-ESI-TOF revealed the metabolic profile of SCAI, finding the pseudo-molecular ions and characteristic fragments, mainly flavonols (10) such as quercetin, kaempferol, isorhamnetin, and its glycosides, as well as chlorogenic acid (CA). Eleven substances were identified, confirming the compatibility of the metabolic profile presented in varieties canadensis and scabra of european S. canadensis. The both contain the same flavonoid aglycones, and their glycosides are important chemical and biological markers for extracts and products based on species of the genus Solidago. UFLC-PDA-ESI-TOF characterized the extracts, which can help with quality control of raw plant materials and commercialized phytotherapeutics as well as for development of new products and phytomedicines.
