“…merrillii ( T. grandis ) is mainly distributed in Southeast China.Its kernel oil contains about 10–13% sciadonic acid [10,11,12]. Recently, several studies reported that kernel oil of T. grandis has strong antioxidant activity in radical scavenging tests [13,14,15]. Torreya fargesii ( T. fargesii ) is an endemic species that grows in the mountainous areas of Central and Southwest China.…”

Polymethylene-interrupted polyunsaturated fatty acids (PMI-PUFAs) are emerging functional lipids with proven antioxidant and anti-inflammatory effects. In this study, a typical PMI-PUFA, sciadonic acid (C20:3, 5c 11c 14c), was enriched in the kernel oil of Torreya fargesii (T. fargesii) by fractionation. Fractionated kernel oil of T. fargesii (containing 25% sciadonic acid) showed equal stability and similar radical scavenging ability compared with the non-fractionated oil. In anti-inflammatory tests, fractionated kernel oil was shown to inhibit the activity of phosphodiesterase (PDE-5, efficiency 80% at 133.7 μg/mL) and lipoxygenase-5 (LOX-5, efficiency 65% at 66.7 μg/mL) more effectively than the non-fractionated oil. This shows that increasing the amount of sciadonic acid can enhance the anti-inflammatory effect of the kernel oil. This research also indicates that fractionation is a feasible way to obtain sciadonic acid–rich functional oil with potential pharmacological effects.

“…The aril extract of Torreya G gave an IC 50 as 1.55 mg/mL (about 1 mg GAE/mL) (Bao, 2010) while the pure flavonoids extract from aril of Torreya G presented IC 50 at 0.063 mg/mL in another report (He et al, 2015). For the essential oil extract from the aril of Torreya G, the IC 50 on DPPH was less effective (17.13 mg/mL) (Yu et al, 2016). A research on polyphenolic-enriched apple skin extract showed the IC 50 about 0.036 GAE mg/mL in the fish oil with 12% DHA (Vasantha, Naciye, & Afsana, 2010).…”

“…The further utilization with these waste arils became an emerging task in Southwest China. Previous researches already separated out several chemicals, such as the protein, kernel oil, limonene, polyphenols and flavonoids, from the Torreya G (Chen et al, 2006;Ni et al, 2015;Yu, Ni, Wu, & Sang, 2016;Yu, Zeng, Qin, He, & Chen, 2017). The lipids and terpenoids were usually extracted by petroleum ether or hexane; the extraction by ethanol usually produced the hydrosoluble polyphenols and flavonoids.…”

The hydrosoluble extract from a processing waste, aril of Torreya fargesii Franch. (abbr.as Torreya F), was investigated for its antioxidative properties and resulting protective effect on the oxidation of DHA (docosahexaenoic acid) algal oil. The aril extract of Torreya F contained about 125.2 mg GAE/g dry extract total polyphenols and 18.5 mg RT/g dry extract total flavonoids. The scavenging ability on the DPPH (1,1-diphenyl −2-picrylhydrazyl), hydroxyl and superoxide anion radicals of aril extract of Torreya F was stronger than that of commercial ascorbyl palmitate. With the addition of Torreya F aril extract, the increasing peroxide value and acid value of DHA algal oil was inhibited both in the long-term storage test and the accelerating Schaal test.Actividad antioxidante de los extractos del arilo de Torreya fargesii Franch. y su protección ante la oxidación del aceite de alga DHA RESUMEN En el presente estudio se investigó el extracto hidrosoluble obtenido de un desecho de procesamiento, el arilo de Torreya fargesii Franch. (abreviado como Torreya F), con el objetivo de determinar sus propiedades antioxidantes y el efecto protector resultante ante la oxidación del aceite de alga DHA (ácido docosahexaenoico). Se comprobó que el extracto del arilo de Torreya F contiene alrededor de 125.2 mg GAE/g del extracto deshidratado de polifenoles totales y 18.5 mg RT/g del extracto deshidratado de flavonoides totales. La capacidad de captación de DPPH (1,1-difenil -2picrilhidrazil), hidroxilo y radicales aniones superóxidos del extracto de arilo de Torreya F fue mayor que la del palmitato ascorbilo comercial. A partir de la adición del extracto de arilo de Torreya F se inhibió el incremento de los valores peróxido y ácido del aceite de alga DHA, tanto en la prueba de almacenamiento de largo plazo como en la prueba de Schaal acelerada.

Several chitosan sodium tripolyphosphate (TPP) nanoparticles embedded with Torreya grandis aril essential oils (TEOs) were synthesized using an emulsion-ionic gelation technique. Mannosylerythritol lipid A (MEL-A), a type of biosurfactant, was selected as the emulsifier. In order to replace acetic acid, an ionic liquid (IL) was employed to dissolve chitosan. The physical properties, diameters, morphology, embedding rate, and antibacterial effects of those essential oil loaded chitosan (CS) nanoparticles were characterized. The results demonstrated that chitosan nanoparticles can be successfully prepared in an ionic liquid containing system and the diameters for nanoparticles in acetic acid and ionic liquid solutions are 144.1 ± 1.457 and 219.0 ± 4.045 nm. After loading with essential oils, the size increased to 349.6 ± 10.55 and 542.9 ± 16.74 nm, respectively. Antibacterial properties were investigated by the observation of the inhibition zone against S. aureus. The results revealed that TEO loaded nanoparticles synthesized in acid and IL aqueous systems have stronger antibacterial activities than CS nanoparticles.
