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]

open access: yesIndustrial Crops and Products, 2016
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 ...

Application of GC × GC coupled with TOF–MS for the trace analysis of chemical components and exploration the characteristic aroma profile of essential oils obtained from two tree peony species (Paeonia rockii and Paeonia ostii)

European Food Research and Technology, 2021
Tree peony essential oil (EO) is a critical material for flavor and function in the industrial fields of perfume, medicine and food. To conduct an overall analysis of different varieties of tree peony EOs, the composition, aroma characteristics and antioxidant activity of ZiBan and FengDan EOs were analyzed by two-dimensional gas chromatography and ...

Synergistic mechanism of hydrophobic and hydrophilic antioxidants in the interface of tree peony seed oil bilayer emulsion

Food Chemistry
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 ...

A novel microwave-assisted steam distillation approach for separation of essential oil from tree peony (Paeonia suffruticosa Andrews) petals: Optimization, kinetic, chemical composition and antioxidant activity

Industrial Crops and Products, 2020
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 ...

Synthesis and application of novel silver magnetic amino silicone adhesive particles for preparation of high purity α-linolenic acid from tree peony seed oil under applied magnetic field

Journal of Chromatography A, 2020
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.
