In natural product research, beyond extraction efficiency, the environmental impact of solvents is gaining increasing attention.The use of environmentally safer solvents in extraction processes requires greater consideration.This study introduces, for the first time, an extraction method utilizing bio-based solvents to extract triterpenoids from biomass.Various green solvents were evaluated and carefully selected for the extraction of betulinic acid from Tetracera scandens.Results indicated that aqueous solutions of pentane-1,2-diol and hexane-1,2-diol provided the highest extraction yield.Response surface methodol. was applied to optimize the extraction process, and a second-order kinetic model was applied to elucidate the extraction mechanism.Extraction yields were 9.87 mg/g for pentane-1,2-diol and 8.58 mg/g for hexane-1,2-diol.Betulinic acid was successfully recovered from the extract using a solid-liquid extraction method with macroporous resins.Both the green solvents and resins were efficiently reused for at least three extraction-recovery cycles, with extraction yields of 8.69-9.78 mg/g, betulinic acid recovery of 88.49-96.06 %, betulinic acid purity of 54.30-56.57 %, and solvent recovery of 95.33-97.50 %, all maintained throughout the process.The betulinic acid-rich extract obtained using bio-based solvents exhibited superior potential against AGS, MCF-7, HepG2, and HeLa tumor cell cultures, as well as α-glucosidase inhibitory and antioxidant activities, compared to traditional organic solvent extractsThe comprehensive findings of this study offer valuable insights for future research exploring the potential of bio-based solvents in triterpenoid extraction from biomass and encourage further large-scale studies aimed at sustainable and environmentally friendly development.
