Xao tam phan (Paramignya trimera (Oliv.) Guillaum) is often a Vietnamese traditionally medicinal plant utilized 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 study aimed to research 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 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, in comparison to conventional and ultrasound-assisted extractions. These data reveal that using methanol and microwave-assisted extraction are recommended 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 various drying methods, various solvents and extraction methods about the phytochemical compounds and antioxidant capacity from Xao tam phan (Paramignya trimera) root extracted from Vietnam. The outcomes demonstrated that microwave drying was a powerful method in eliminating water when it comes to shortest drying time, lowest energy consumption as well as retention of phytochemical compounds and antioxidant capacity in the P. trimera root while methanol and microwave-assisted extraction were the top solvent and way for greatest extraction from the phytochemical compounds and antioxidant capacity from your P. trimera root. The findings from this study allow retaining the very best numbers of phytochemical compounds and antioxidant capacity from the P. trimera root for potential application in the nutraceutical industry.
