Xao tam phan (Paramignya trimera (Oliv.) Guillaum) is often a Vietnamese traditionally medicinal plant utilized in the management 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 analyze the 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 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 with conventional and ultrasound-assisted extractions. These data show the application of methanol and microwave-assisted extraction are recommended for extraction of biologically active phytochemicals from P. trimera root for application from 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 with this study could determine the consequences of different drying methods, various solvents and extraction methods around the phytochemical compounds and antioxidant capacity from Xao tam phan (Paramignya trimera) root extracted from Vietnam. The results showed that microwave drying was an effective method in elimination of water in terms of 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 very best solvent and means for greatest extraction with the phytochemical compounds and antioxidant capacity from your P. trimera root. The findings out of this study allow retaining the best amounts of phytochemical compounds and antioxidant capacity through the P. trimera root for potential application from the nutraceutical industry.
