Xao tam phan (Paramignya trimera (Oliv.) Guillaum) is a Vietnamese traditionally medicinal plant used 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 research 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 greatest antioxidant capacity, with eleven compounds were identified and quantified. Microwave-assisted extraction produced the maximal phytochemical yields (aside from total flavonoids) and antioxidant capacity, in comparison with conventional and ultrasound-assisted extractions. These data show 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 affect the phytochemical compounds and biological activity from plant materials. The aims with this study could determine the effects of various drying methods, various solvents and extraction methods on the phytochemical compounds and antioxidant capacity from Xao tam phan (Paramignya trimera) root obtained from Vietnam. The final results established that microwave drying was an effective method in removal of water with regards to 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 very best solvent and means for greatest extraction of the phytochemical compounds and antioxidant capacity from your P. trimera root. The findings out of this study allow retaining the highest amounts of phytochemical compounds and antioxidant capacity from your P. trimera root for potential application in the nutraceutical industry.
