Activity

Xao tam phan (Paramignya trimera (Oliv.) Guillaum) is really a Vietnamese traditionally medicinal plant used 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 investigate the end results 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 greatest 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, when compared to conventional and ultrasound-assisted extractions. These data show the use of methanol and microwave-assisted extraction are suggested for extraction of biologically active phytochemicals from P. trimera root for application inside the nutraceutical and/or pharmaceutical industries.

Drying methods, solvents and extraction methods greatly modify the phytochemical compounds and biological activity from plant materials. The aims of this study would determine the effects of numerous drying methods, various solvents and extraction methods about the phytochemical compounds and antioxidant capacity from Xao tam phan (Paramignya trimera) root purchased from Vietnam. The final results showed that microwave drying was a powerful method in removing water when it comes to shortest drying time, lowest energy consumption and greatest retention of phytochemical compounds and antioxidant capacity from the P. trimera root while methanol and microwave-assisted extraction were the best solvent and way of greatest extraction in the phytochemical compounds and antioxidant capacity from your P. trimera root. The findings out of this study allow retaining the very best numbers of phytochemical compounds and antioxidant capacity through the P. trimera root for potential application in the nutraceutical industry.
