Xao tam phan (Paramignya trimera (Oliv.) Guillaum) is a Vietnamese traditionally medicinal plant found in the treatment of numerous cancers. The preparation of Xao tam phan extracts including solvent type and extraction method have significant effects on extraction efficiency, phytochemical profile and biological activity. This research aimed to investigate the consequences of five various solvents (water, acetonitrile, methanol, ethyl acetate and hexane) and three different extraction methods (conventional, ultrasound-assisted and microwave-assisted) on phytochemical yield and antioxidant capacity of P. trimera root from Vietnam. The results indicate that methanol extracted the maximal yield of phytochemicals from P. trimera and exhibited the best antioxidant capacity, with eleven compounds were identified and quantified. Microwave-assisted extraction produced the maximal phytochemical yields (aside from total flavonoids) and antioxidant capacity, in comparison with conventional and ultrasound-assisted extractions. These data show that the application of methanol and microwave-assisted extraction are suggested for extraction of biologically active phytochemicals from P. trimera root for application within the nutraceutical and/or pharmaceutical industries.
Drying methods, solvents and extraction methods greatly impact the phytochemical compounds and biological activity from plant materials. The aims of the study were to determine the consequences of numerous drying methods, various solvents and extraction methods around the phytochemical compounds and antioxidant capacity from Xao tam phan (Paramignya trimera) root from Vietnam. The outcome demonstrated that microwave drying was an effective method in removing water regarding shortest drying time, lowest energy consumption as well as retention of phytochemical compounds and antioxidant capacity from the P. trimera root while methanol and microwave-assisted extraction were the best solvent and means for greatest extraction in the phytochemical compounds and antioxidant capacity through the P. trimera root. The findings from this study allow retaining the greatest levels of phytochemical compounds and antioxidant capacity from the P. trimera root for potential application inside the nutraceutical industry.
