Abstract
This study develops hemp seed globulin (GLB)-alginate (ALG) nanoparticles (GANPs) for Cannabisin A (CA) stabilization under environmental stress and during pepsin digestion. The optimal GLB: ALG mass ratio of 1: 1.5 was determined for GANPs formation at pH 3.5, resulting in a high yield of 95.13 ± 0.91 %, a ζ-potential of -35.73 ± 1.04 mV, a hydrodynamic diameter of 470.67 ± 11.36 nm, and a PDI of 0.298 ± 0.016. GANPs were employed to encapsulate CA, achieving a high loading capacity of 13.48 ± 0.04 μg mg-1. FTIR analysis demonstrated that the formation of CA-GLB-ALG nanoparticles (CGANPs) involves electrostatic interactions, hydrogen bonding, and hydrophobic interactions. XRD and DSC analyses revealed that CA is amorphous within the CGANPs. CGANPs demonstrated remarkable dispersion stability as well as resistance to high ionic strength and high-temperature treatments, indicating their potential as efficient hydrophobic drug-delivery vehicles. When compared to free CA, CA coated within CGANPs displayed greater DPPH/ABTS scavenging activity. Furthermore, the ALG-shelled nanoparticles protected GLB from pepsin digestion and slowed the release of CA throughout the release process, extending their stay on the intestinal wall mucosa. These findings imply that CGANPs is an ideal delivery vehicle for CA as they may expand the application of CA in food items.

Abstract
This study focused on elucidating the non-covalent interactions between hemp seed globulin (GLB) and two hemp seed phenolic compounds, Cannabisin A (CA) and Cannabisin B (CB), and to explore these interactions on the protein's structure, conformation, and functionality. Fluorescence quenching and thermodynamic analysis revealed that static quenching governed non-covalent interaction processes, with hydrogen bonds and van der Waals forces functioning as major forces. This was further substantiated by molecular docking studies. The binding affinity order was CA > CB, indicating that the specific phenolic compound had a notable impact on the binding affinity. Furthermore, when complexed with CA, Tyr and Trp residues were exposed to a more hydrophilic environment than when complexed with CB. It was noted that the complexation with either CA or CB consistently affects GLB's secondary structure, particle size, and ζ-potential. GLB treated with the phenolic compounds exhibited enhanced ABTS and DPPH scavenging activities and improved digestibility compared to untreated GLB. Furthermore, the non-covalent interactions significantly increased CA's water solubility, highlighting GLB as a promising natural carrier for hydrophobic bioactive components. These findings hold potential implications for enhancing hemp seed protein applications within the food industry by positively influencing its functional properties and bioactivity.

Abstract
In the present study, we investigated the protection of hemp seed polyphenols on human umbilical vein endothelial cells (HUVEC) from H2 O2 -mediated oxidative stress injury. Fractions with different polarities were obtained by separating the hemp seed extract using HPD300 macroporous resin-packed column. The fraction, desorbed by 50% ethanol, is rich in polyphenol (789.51 ± 21.92 mg GAE/g) and has the highest antioxidant activity in vitro. HPLC-QTOF-MS/MS identified the main polyphenol components in hemp seed shells: 4 hydroxycinnamic acid amides and 15 lignanamides. The protective effects of hemp seed polyphenol against oxidative-stress injury in HUVEC cells were evaluated by cell viability, intracellular antioxidant parameters, and cell apoptosis assay. After HUVEC cells were precultured with 50 µg/ml hemp seed polyphenols, the cell viability increased significantly from 53.07 ± 2.46% (model group) to 80.65 ± 1.32% (p < 0.01). In addition, the pretreatment of HUVEC cells with polyphenol could substantially increase their intracellular superoxide dismutase activity and reduce their intracellular reactive oxygen species level, malondialdehyde content, and lactate dehydrogenase leakage index. These findings demonstrate the defensive potential of hemp seed polyphenol in reducing the incidence of cardiovascular disease. PRACTICAL APPLICATION: Hemp seed shell waste is produced while producing hemp seed kernel and has abundant phenolic compounds. This research showed that hemp seed polyphenol has potent antioxidant activity in vitro and protects HUVEC cells against H2 O2 -induced oxidative stress injury, suggesting that hemp seed polyphenol has the defensive potential to reduce the incidence of cardiovascular disease. These results indicated that polyphenol separated from hemp seed shells is valuable for further research and development, which will improve the utilization rate of hemp seed.

Abstract
Phytochelatins (PCs) have been proposed as a potential biomarker for metal toxicity. In this study, cadmium (Cd) toxicity, PCs production and their relationship in wheat under Cd stress were examined using various exogenous organic chelator-buffered nutrient solutions. Single Cd stress produced strong toxic effects, as indicated by decreases of growth parameters, high level of lipid peroxidation in leaf and overproduction of PCs in root. Exogenous organic chelators with proper dose more or less reduced Cd toxicity by increasing growth parameters and decreasing lipid peroxidation in leaves. Of organic chelators (EDTA, DTPA, citric acid, malic acid and oxalic acid), EDTA was the most effective in decreasing Cd toxicity in plants, followed by DTPA and citric acid. Simultaneously, the concentrations of Cd-induced PCs in roots decreased, and the greatest decrease was caused by application of EDTA and DTPA. Linearly positive relationships were observed between Cd toxicity and root PCs concentrations under the influences of organic chelators, particularly EDTA, DTPA and citric acid. Furthermore, present results provide stronger evidence that PCs synthesis in plant cells was related to free Cd ion concentrations, not total Cd, and demonstrate that the levels of PCs production in plants correlated well with toxic effects caused by the bioavailable Cd levels.

Abstract
It has been proposed that phytochelatins (PCs) act as a biomarker for the evaluation of metal toxicity. Little attention has been paid to the effects on metal combinations and glutathione (GSH), the most abundant cellular thiol. In the present study the effects of interactions between cadmium (Cd) and zinc (Zn) on PC and GSH production were examined in wheat tissue over 14 days' exposure. The results showed that the presence of Zn alleviated Cd toxicity, accompanied by a reduction of Cd uptake. Cd and Zn exposure increased PC-SH levels in concentration-, tissue- and time-dependent manners. Of the two metals, Cd was more effective than Zn in PC-SH production. Interactions of Cd and Zn with respect to PC-SH production may be synergistic or inhibitory, strongly depending on duration of exposure and concentration of the metal combinations. Cd also stimulated GSH production in concentration-, tissue- and time-dependent manners, whereas Zn had no significant effects on GSH levels. Compared to the presence of Cd alone, the presence of Zn reduced GSH levels in a tissue-dependent manner over the growth period. The results of the study suggest that metal interactions should be highly considered in the application of PCs and GSH as potential biomarkers for the evaluation of metal toxicity, as most metal-polluted natural environments are contaminated with more than one metal.
