Key Findings

  • Researchers at the Federal Institute of Paraná optimized a green extraction technique to extract β-ecdysone from Pfaffia glomerata
  • The study found that the stem of the plant had the highest yield of β-ecdysone at 0.764%
  • High-Performance Liquid Chromatography confirmed β-ecdysone in all plant parts, with the highest concentration in the stems
Pfaffia glomerata (Spreng.) Pedersen, a plant known for its medicinal properties, has been the subject of recent research conducted by the Federal Institute of Paraná[1]. This study focused on extracting β-ecdysone, a phytoestrogen with various beneficial effects, from different parts of the plant using a green extraction technique known as pressurized liquid extraction (PLE). The study aimed to optimize the extraction process and evaluate the presence and concentration of β-ecdysone in the leaves, stems, and roots. The research employed a 22 factorial design to assess the impact of temperature and flow rate on the extraction yield. The variables tested included temperatures of 333 K and 353 K, and flow rates of 1.5 and 2 mL min-1, while maintaining a constant pressure of 300 Bar, extraction time of 60 minutes, and a solvent mixture of ethanol and distilled water (70:30 v/v). The experimental results indicated that both temperature and flow rate significantly influenced the yield of β-ecdysone from the different plant parts, with the stem extract showing the highest yield at 0.764%. High-Performance Liquid Chromatography (HPLC) analysis confirmed the presence of β-ecdysone in all parts of the plant, with concentrations of 86.82 mg L-1 in the leaves, 76.53 mg L-1 in the roots, and 195.86 mg L-1 in the stems. Additionally, Fourier Transform Raman (FT Raman) spectroscopy revealed characteristic peaks of β-ecdysone, further validating the successful extraction process. An interesting finding was the presence of a peak at 1460 cm-1 in the root extract, potentially indicating the presence of selenium. Previous studies have highlighted the pharmacological benefits of β-ecdysone and other bioactive compounds in Pfaffia glomerata. For instance, the identification of various compounds such as flavonoid glycosides and triterpenoid saponins in the inflorescences of P. glomerata suggests its potential applications in the phytotherapeutic and cosmetic industries[2]. Additionally, another study demonstrated the gastroprotective effects of an aqueous extract of P. glomerata, which effectively protected the gastric mucosa and inhibited gastric acid secretion in rats[3]. These findings underscore the therapeutic potential of P. glomerata and provide a broader context for the significance of the current study. The use of PLE as a green extraction technique aligns with the growing emphasis on sustainable and environmentally friendly methods in scientific research. By optimizing temperature and flow rate, the researchers were able to maximize the yield of β-ecdysone, thereby enhancing the efficiency of the extraction process. This study not only confirms the presence of β-ecdysone in various parts of P. glomerata but also establishes a reliable method for its extraction, which could facilitate further research and potential commercial applications. In conclusion, the study conducted by the Federal Institute of Paraná provides valuable insights into the extraction of β-ecdysone from Pfaffia glomerata using PLE. The findings build upon previous research[2][3] and highlight the plant's potential for various therapeutic applications. The successful optimization of the extraction process marks a significant step forward in the utilization of P. glomerata's bioactive compounds, paving the way for future studies and potential industrial applications.
