Xao tam phan (Paramignya trimera (Oliv.) Guillaum) is often a Vietnamese traditionally medicinal plant utilized in treating 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 effects of 5 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 final results indicate that methanol extracted the maximal yield of phytochemicals from P. trimera and exhibited the greatest antioxidant capacity, with eleven compounds were identified and quantified. Microwave-assisted extraction produced the maximal phytochemical yields (except for total flavonoids) and antioxidant capacity, when compared to conventional and ultrasound-assisted extractions. These data show that using methanol and microwave-assisted extraction are suggested for extraction of biologically active phytochemicals from P. trimera root for application in the nutraceutical and/or pharmaceutical industries.

Drying methods, solvents and extraction methods greatly get a new phytochemical compounds and biological activity from plant materials. The aims with this study would determine the consequences of numerous drying methods, various solvents and extraction methods for the phytochemical compounds and antioxidant capacity from Xao tam phan (Paramignya trimera) root obtained from Vietnam. The outcomes demonstrated that microwave drying was a powerful method in removal of water regarding shortest drying time, lowest energy consumption as well as retention of phytochemical compounds and antioxidant capacity from your P. trimera root while methanol and microwave-assisted extraction were the best solvent and way for greatest extraction in the phytochemical compounds and antioxidant capacity from your P. trimera root. The findings from this study allow retaining the highest levels of phytochemical compounds and antioxidant capacity from your P. trimera root for potential application from the nutraceutical industry.
