The complete chloroplast genome sequence of Pinus cembra L. (Pinaceae)

The Swiss pine (Pinus cembra) is a montane tree in Central Europe and, therefore, known for its hardiness against severe winter colds. The seeds are harvested and eaten as pine nuts. We assembled and characterized the complete chloroplast genome of P. cembra to serve as a valuable resource in future genetic studies. The complete plastome […]

Comparative analysis of volatile profiles in two grafted pine nuts by headspace-SPME/GC-MS and electronic nose as responses to different roasting conditions

As an attempt to fulfill the massive demand for pine nuts, two grafted trees were cultivated: grafted Pinus koraiensis on the same scions (PK) and grafted Pinus koraiensis on Pinus sylvestris rootstocks (PKS) trees. Both PK and PKS are acknowledged as important economic trees in the northeastern area of China. This study aimed to compare […]

The association between left ventricular hypertrophy and consumption of nuts, including peanuts, pine nuts, and almonds

Background and aims: Studies have reported that nut consumption is potentially beneficial in preventing cardiovascular disease. However, data are insufficient regarding the association between nut consumption and left ventricular hypertrophy (LVH). Methods and results: In the Kangbuk Samsung Health Study, the participants were 34,617 men and 12,257 women who completed a food-frequency questionnaire for nut consumption and […]

Epitope mapping of the major allergen 2S albumin from pine nut.

The epitopes of the major allergen of pine nut, Pin p 1, were analyzed using a peptide library and sera from patients with clinical allergy to pine nut in order to deepen into the allergenic characteristics of Pin p 1. Analyses of epitope similarities and epitopes location in a 3D-model were also performed. Results showed […]

The Effect of Chilgoza Pine Nut (Pinus gerardiana Wall.) on Blood Glucose and Oxidative Stress in Diabetic Rats.

Purpose: Diabetes can increase oxidative stress in various tissues of the body, and the progress of this process is associated with intensification of the complications of diabetes. The current study purposed to evaluate the protective effect of Pinus gerardiana (PG) seed on oxidative stress induced by diabetes in the liver and serum of streptozotocin (STZ)-induced diabetic rats. Materials […]

Investigation of effectiveness of pyrolysis products on removal of alizarin yellow GG from aqueous solution: A comparative study with commercial activated carbon.

The increasing use of dyestuff in industrial applications brings with it environmental problems. These dyes, which are an eco-toxic hazard, are common water pollutants, even at very low concentrations in water resources. Therefore, they must be removed in an economical way. In this study, low-cost biosorbents such as pine cone char, walnut shell char, and […]

Cetyl trimethyl ammonium bromide modified magnetic biochar from pine nut shells for efficient removal of acid chrome blue K.

Biochar was prepared by rapid pyrolysis using pine nut shell as raw materials. Then cetyl trimethyl ammonium bromide modified magnetic biochar material (CTAB-MC) was obtained after modifying biochar by FeCl3 and cetyl trimethyl ammonium bromide. The CTAB-MC was characterized by SEM, FTIR, XRD and Magnetic analyses. Adsorptive property of the CTAB-MC for acid chrome blue K […]

Identification of Polymethylene-Interrupted Polyunsaturated Fatty Acids (PMI–PUFA) by Solvent-Mediated Covalent Adduct Chemical Ionization Triple Quadrupole Tandem Mass Spectrometry.

Pine nuts and other edible gymnosperm seeds contain unusual, bioactive polymethylene-interrupted polyunsaturated fatty acids (PMI-PUFAs), a subset of nonmethylene-interrupted PUFA with (-CH2-)n≥2 intervening between double bonds. Conventional methods for structure elucidation of PMI-PUFAs require special derivatization risking rearrangement artifacts. Here we introduce a facile solvent-mediated (SM) covalent adduct chemical ionization (CACI) system modified with a triple […]

Chemical characterization, antioxidant evaluation, and antidiabetic potential of Pinus gerardiana (Pine nuts) extracts.

Methanolic and ethyl acetate extracts of pine nuts were evaluated for in vitro antioxidant and inhibition of alpha-amylase activities. Pine nut extracts were orally administered to alloxan monohydrate-induced diabetes in mice at 250, 500, and 750 mg/kg. Both extracts showed a significant antioxidant and inhibition of alpha-amylase activities. Animal studies showed a decline in fasting […]
