Simultaneous synergistic microwave–ultrasonic extraction and hydrolysis for preparation of trans-resveratrol in tree peony seed oil-extracted residues using imidazolium-based ionic liquid [PDF]
Abstract Imidazolium-based ionic liquid-based microwave–ultrasonic synergistic simultaneous extraction and hydrolysis (IMUSEH) method was developed to obtain trans-resveratrol from tree peony (Paeonia rockii (S.G. Haw & Lauener) T. Hong & J.J. Li) seed oil-extracted residues, in which the basic ionic liquid aqueous solution was used for extraction ...

AbstractAs a new woody oleaginous crop, tree peony is now being widely developed and utilized, which attributed to the outstanding oil‐use features regarding the fatty acid profiles and bioactivity. The major fatty acid profiles and bioactivity of seed oils in ten tree peony varieties collected from a common garden were investigated in the present ...

Interplay between hydrophobic and hydrophilic antioxidants in bilayer emulsions remains unclear, especially within the unique, thicker interface of layer-by-layer assembled systems. This study investigates the antioxidant behavior and interaction mechanism of α-tocopherol (hydrophobic) and l-ascorbic acid (hydrophilic) in tree peony seed oil (TPSO ...

Abstract Microwave-assisted steam distillation (MSD) was developed as an efficient technique for the separation of essential oil (EO) from tree peony (Paeonia suffruticosa Andrews) petals, on the basis of ensuring the extraction of flavonoids. During MSD process, the raw material was separated from water to keep it in a relatively dry state, thus ...

Silver magnetic amino silicone adhesive (Fe3O4@SiO2@NH2@Ag) particles were prepared for the purification of α-linolenic acid from tree peony seed oil under applied magnetic field. First, Fe3O4@SiO2@NH2@Ag particles were prepared and physicochemically characterized, including XRD, TG, FTIR, SEM, magnetic hysteresis curves and elemental analysis.
