Xao tam phan (Paramignya trimera (Oliv.) Guillaum) is really a Vietnamese traditionally medicinal plant employed 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 look into the consequences 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 outcome indicate that methanol extracted the maximal yield of phytochemicals from P. trimera and exhibited the highest 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 with conventional and ultrasound-assisted extractions. These data reveal 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 affect the phytochemical compounds and biological activity from plant materials. The aims of this study could determine the effects of different drying methods, various solvents and extraction methods on the phytochemical compounds and antioxidant capacity from Xao tam phan (Paramignya trimera) root from Vietnam. The final results established that microwave drying was an effective method in elimination of water regarding 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 best solvent and way for greatest extraction from the phytochemical compounds and antioxidant capacity from the P. trimera root. The findings out of this study allow retaining the greatest numbers of phytochemical compounds and antioxidant capacity from your P. trimera root for potential application within the nutraceutical industry.
