Abstract
En 中文
A novel, green, and efficient micellar extraction and in situ cloud point enrichment technique based on poloxamer was developed to simultaneously extract and concentrate terpenoids from Curcumae Rhizoma. The parameters that affect the extraction efficiency of target analytes were thoroughly explored and optimized via single-factor and multifactor experiments. The maximum extraction yield of terpenoids was attained with 321.672 mg of poloxamer 188, 1.908 g of salt, an extraction time of 32.240 min, a pH of 7, and a heating time of 10 min. The new method exhibited correlation coefficients exceeding 0.9990 and demonstrated good linearity within the range of 0.5-100.0 mu g/mL. It achieved a satisfactory recovery rate within the range of 86.768-101.334%, had a low limit of detection of 0.0020-0.0488 mu g/mL, and showed acceptable reproducibility, with a value of <1.592%. The results demonstrated that the proposed method was successfully employed for the extraction of terpenoids from medicinal plant.
