Determination of ?-ecdysone in infusions of different organs of Brazilian ginseng (Pfaffia glomerata) by high-performance liquid chromatography

Abstract: A Pfaffia glomerata (Spreng.) Pedersen é uma planta medicinal conhecida como ginseng brasileiro. Tradicionalmente, apenas as suas raízes são utilizadas para fins comerciais, em função do seu teor conhecido de β-ecdisona. Neste trabalho, as concentrações de β-ecdisona em infusões aquosas de folhas, flores, raízes e caules de indivíduos de seis meses e de três anos de idade foram determinadas por cromatografia líquida de alta eficiência (HPLC). As análises foram realizadas em HPLC LC-4000 Jasco®, com uma coluna … Show more

“…The material was dried in an air circulation oven (model 400‐4ND, Ethik Technology, SP, Brazil) at 60 °C until the moisture content reached 10% on a dry weight basis. Hydrodistillation was performed for 1.5 h in a Clevenger apparatus, using a 5 L volumetric flask containing 160 g of root and 1 L of water (Martins et al ., 2020).…”
