    Xao tam phan (Paramignya trimera (Oliv.) Guillaum) is often a Vietnamese traditionally medicinal plant found in the 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 study aimed to analyze the end results 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 outcomes 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 (with the exception of total flavonoids) and antioxidant capacity, in comparison to conventional and ultrasound-assisted extractions. These data reveal that the application of methanol and microwave-assisted extraction are recommended 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 get a new phytochemical compounds and biological activity from plant materials. The aims of this study could determine the results of various drying methods, various solvents and extraction methods around the phytochemical compounds and antioxidant capacity from Xao tam phan (Paramignya trimera) root obtained from Vietnam. The outcome showed that microwave drying was a powerful method in removing water when it comes to shortest drying time, lowest energy consumption as well as retention of phytochemical compounds and antioxidant capacity through the P. trimera root while methanol and microwave-assisted extraction were the best solvent and method for greatest extraction of the phytochemical compounds and antioxidant capacity from the P. trimera root. The findings using this study allow retaining the best numbers of phytochemical compounds and antioxidant capacity from the P. trimera root for potential application within the nutraceutical industry.
