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 research aimed to research the consequences 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 maximum 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 demonstrate that using methanol and microwave-assisted extraction are suggested 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 affect the phytochemical compounds and biological activity from plant materials. The aims on this study would determine the end results of different drying methods, various solvents and extraction methods on the phytochemical compounds and antioxidant capacity from Xao tam phan (Paramignya trimera) root extracted from Vietnam. The outcomes indicated that microwave drying was an efficient method in removing water when it comes to shortest drying time, lowest energy consumption and greatest retention of phytochemical compounds and antioxidant capacity through the P. trimera root while methanol and microwave-assisted extraction were the very best solvent and method for greatest extraction in the phytochemical compounds and antioxidant capacity in the P. trimera root. The findings using this study allow retaining the very best amounts of phytochemical compounds and antioxidant capacity from your P. trimera root for potential application from the nutraceutical industry.
