Pinecone polyphenols are bioactive dietary constituents that enhance health and help prevent and treat cancer through improving antioxidant and immunoregulatory activities. This study was designed to investigate the antitumor, antioxidant and immunoregulatory activities of the 40% ethanol eluent of
Effects of pulse electric field (PEF) on antioxidant activity of pine nut (Pinus koraiensis) peptide were discussed using H2O2-induced HepG2 cells and changes of peptide structures were measured by MIR, NMR and CD spectra. Using HPLC-MS/MS, a novel peptide was identified as QDHCH. After PEF
In the present study, two novel peptides Lys-Trp-Phe-Cys-Thr (KWFCT) and Gln-Trp-Phe-Cys-Thr (QWFCT) were purified and identified from 3 to 10kDa pine nut (Pinus koraiensis) meal protein. Their cytotoxicity and antioxidant activities in vitro were determined. Additionally, pulsed electric field
In this study, an orthogonal array design OA₉ (3⁴) was employed to optimise the conditions of supercritical carbon dioxide (SC-CO₂) extraction of Pinus koraiensis nut oil. The effects of pressure, temperature and extraction time on the oil yield were investigated. Next, the fatty acid composition of
This study investigated the physicochemical properties, bioaccessibility and in vitro antioxidant ability of the polyphenols isolated from the pine cones of Pinus koraiensis (PKP) under the simulated gastrointestinal digestion. The results found that PKP was mainly composed by derivatives of
We used a pulsed electric field (PEF) to treat four pentapeptides with similar amino acid sequences (KCHKP, KCHQP, QCHKP, and QCHQP). We then evaluated antioxidant activity of the pentapeptides according to ferric reducing antioxidant power (FRAP) and hydroxyl radical scavenging capacity. Structures
Pinus koraiensis polysaccharides (PKP) were extracted by hot water from P. koraiensis pine cones. Five polysaccharide fractions named PKP-A, PKP-B, PKP-C, PKP-D and PKP-E were successfully separated at final ethanol concentrations of 30%, 50%, 60%, 70% and 80%, respectively. HPLC, FT-IR, GC-MS and
The aim of this study was to investigate the possible mechanism for increasing the antioxidant activity on peptide Glutamine-Tryptophan-Phenylalanine-Histidine (QWFH) from pine nut (Pinus koraiensis) protein by a pulsed electric field (PEF). The antioxidant capacity of PEF-treated QWFH increased
Age-related neuronal injury and oxidative damage are the predominant factors for neurodegenerative diseases like Alzheimer's disease (AD). The aim of this study was to explore whether chronic administration of d-galactose (d-gal) can cause neuronal injury and oxidative damage, and to investigate the
Here, the chitosan and the glutaraldehyde (GA) were used to encapsulate pinecones polyphenols of Pinus koraiensis (P. koraiensis) by emulsification cross-linking technology. First, the prepared parameters (crosslinking agent amount, stirring speed, crosslinking temperature and emulsifying time) of
A new purified polysaccharide (PNP40c-1) with a molecular weight of 2.06 × 105 Da was obtained from pine nuts (Pinus koraiensis Sieb. et Zucc.). Structural analysis indicated that PNP40c-1 is a homogeneous heteropolysaccharide composed of arabinose, rhamnose and glucose in a molar ratio
Background. Dyslipidemia has been well-known as a common metabolic disorder contributing to cardiovascular disease. The aim of this study was to evaluate the effect of the Pinus koraiensis needle extracts (PKE) on the blood cholesterol and oxidative stress. Method. We conducted a 12-week randomized,

The aim of this study was to evaluate radioprotective effect of extracts of Pinus koraiensis bark and its fractions on rat splenocytes by using bioassay-guided isolation in order to obtain the best active fraction.
UNASSIGNED
P. koraiensis bark was ground and extracted with water, 40%
Although Pinus koraiensis leaf (PKL) was reported for its anti-diabetes, anti-obesity and anticancer effects as a folk remedy, the inhibitory effect of PKL on alcoholic fatty liver has never been elucidated yet. This study investigated the molecular mechanisms of PKL on alcoholic fatty liver in
A novel polysaccharide (PNP80b-2) was obtained from Pinus koraiensis pine nut, which has been proved to possess good hepatoprotective effects in vitro. This study comprehensively investigated its hepatoprotective activities against different types of chemical-induced liver injury in vivo. Carbon
