This study evaluated the potential of Artemisia sphaerocephala Krasch gum (ASK gum) solution as a fat replacer. With an increased proportion of ASK gum, the fat and energy of frankfurters significantly decreased, the cooking yield significantly increased, and the L * values exhibited an upward trend. Frankfurters with 75% pork back fat substitution by ASK gum yielded optimal gel strength and texture. Low-field nuclear magnetic resonance (LF-NMR) analysis indicated that ASK gum reduced the T 2 relaxation time and heightened the percentage of immobilized water. Meanwhile, an increase in the β-sheet and decreased α-helix content indicated that ASK gum altered the protein secondary structure. Moreover, ASK gum addition significantly changed the dynamic rheological properties and microstructure. Partial fat substitution with ASK gum did not impact the sensory score. Overall, using ASK gum solution to partially substitute animal fat could be a promising approach for improving the gel quality of reduced-fat frankfurters.

Artemisia sphaerocephala Krasch. polysaccharide (ASKP) contained two fractions of 60P and 60S with different molecular weight. It was found the potential performance of interface adsorption and gelation activities for the high molecular weight of 60P in comparison with low molecular weight of 60S. The emulsion stability and droplets filling in gel network was highly dependent on the medium chain triglyceride (MCT) concentrations. The emulsion gels fabricated through a complexation of 60P and gelatin or collagen peptides exhibited significantly improved emulsifying activity and gel strength at higher concentration of MCT. Gelatin or collagen peptide could be adsorbed on the droplets interface and interact with 60P in gel matrix, thus presenting an active filling. However, 60P based emulsion gel complexed with pullulan contributed to a lower strength than hydrogel, which was probably due to the existence of spaces between droplets and gel matrix, weakening the stability of gel network, considered as an inactive filling.

Flavonoids are a group of phenolic secondary metabolites in plants that have important physiological, ecological and economic value. In this study, using the desert plant Artemisia sphaerocephala Krasch. as the sample material, the content and components of the total flavonoids in its seeds at seven different developmental stages were determined. In addition, the genes involved in flavonoid metabolism were identified by full-length transcriptome sequencing (third-generation sequencing technology based on PacBio RS II). Their expression levels were analysed by RNA-seq short reading sequencing, to reveal the patterns and regulation mechanisms of flavonoid accumulation during seed development. The key results were as follows: the content of total flavonoids in mature seeds was 15.05 mg g−1, including five subclasses: flavonols, chalcones, flavones, flavanones and proanthocyanidins, among which flavonols accounted for 45.78%. The period of rapid accumulation of flavonoids was 40–70 d following anthesis. The high expression of phenylalanine ammonia-lyase (PAL), 4-coumarate-CoA ligase (4CL) and UDP-glucose:flavonoids 3-o-glucosyltransferase (UF3GT) promoted the accumulation of total flavonoids, while the high expression of flavonoids 3′-hydroxylase (F3′H) and flavonols synthase (FLS) made flavanols the main component. Transcription factors such as the MYB-bHLH-WDR (MBW) complex and Selenium-binding protein (SBP) directly regulated the structural genes of flavonoid metabolism, while C2H2-type zinc finger (C2H2), Zinc-finger transcription factor (GATA), Dehydration-responsive element binding (DREB), Global Transcription factor Group E protein (GTE), Trihelix DNA-binding factors (Trihelix) and Phytochrome-interacting factor (PIF) indirectly promoted the synthesis of flavonoids through hormones such as brassinoidsteroids (BRs) and abscisic acid (ABA). These results provided valuable resources for the application of related genes in genetics and breeding.

This study investigates the use of artemisia sphaerocephala krasch gum (ASKG) as a biocompatible pyrite depressant to effectively achieve the flotation of chalcopyrite. The flotation performance of pyrite and chalcopyrite treated with ASKG was investigated through micro-flotation tests, and the interaction mechanism between ASKG and pyrite was systematically studied using various characterization techniques. Micro-flotation results showed that ASKG effectively depresses the flotation of pyrite at pH 8, while its effect on chalcopyrite flotation is negligible. Mixed-mineral micro-flotation tests further demonstrated that, under pH 8.0, the addition of 60 mg/L ASKG and 60 mg/L sodium butyl xanthate (SBX) resulted in a recovery rate of chalcopyrite in the froth product that was 60.46 % higher than that of pyrite. Contact angle measurements and Fourier-transform infrared spectroscopy (FTIR) revealed that ASKG preferentially adsorbs on pyrite rather than on chalcopyrite, and the pre-adsorbed ASKG hinders the subsequent adsorption of SBX on pyrite. X-ray photoelectron spectroscopy (XPS) and molecular dynamics (MD) simulations further confirmed that the –OH group in ASKG acts as the active group interacting with the pyrite surface, forming chemical chelation with ferric hydroxide on the pyrite surface. In conclusion, ASKG shows potential as a pyrite depressant for the selective flotation of chalcopyrite.

Artemisia sphaerocephala Krasch. polysaccharide (ASKP) was found to be crosslinked with ferric ions to form hydrogels in the previous study. In this work, it was demonstrated that ASKP-Fe 3+ hydrogel complexed with pullulan or gelatin contributed to a significantly enhanced gel strength at 1.5% ASKP, 60 mM Fe 2+ , pH 4.0, and the mixing ratio of 9: 1. The complexed hydrogels presented a dense semi-interpenetrating network along with the delay of gelation time and the increase of water retention. ASKP based complexes exhibited good compatibility, probably because pullulan and gelatin could be entangled with ASKP chain under hydrogen bonding and electrostatic interaction, respectively. The interaction between ASKP and pullulan or gelatin contributed to the formation of complexed hydrogels with dense network and significantly enhanced gel strength. It is inferred that ASKP would have great potential to be a new gelling material as well as for the ferric ions delivery.

Buckwheat noodles (WB) are always superior in health effects but inferior in textural quality to wheat noodles (W). Artemisia sphaerocephala Krasch gum (AsKg) has been proven to be an improver for the latter. To elaborate on this, the effects of physical state (dry or pre-hydrated) and addition mode (pre-addition or delayed addition) of AsKg on the quality of buckwheat noodles (buckwheat:wheat = 3:7, w/w) were investigated in this work as four procedures, namely, dry/pre-addition (DP), dry/delayed addition (DD), pre-hydrated/pre-addition (HP), and pre-hydrated/delayed addition (HD). The dough mixing property, water distribution, rheological behavior, the structure of the gluten network, and noodle quality were determined. The results indicated that on most occasions, the improvements were in a procedure order of HP > DD > HD > DP, corresponding to the same order in their levels of gluten hydration. These findings are of practical significance for producing high-quality buckwheat noodles.

Artemisia sphaerocephala Krasch polysaccharide (ASKP) consists of two main fractions, 60P (molecular weight at 551 kDa) and 60S (molecular weight at 39 kDa). The anti-obesity effects of ASKP and its two fractions were investigated in high-fat-diet-fed mice and showed similar capability in efficiently preventing the development of obesity. The final body weight and body weight gain of obesity mice model were reduced by 12.44% and 35.33% by ASKP, 10.63% and 34.35% by 60P, and 7.82% and 20.04% by 60S. They also showed similar efficiency to ameliorate dyslipidemia, systematic inflammation, and gut dysbiosis. The colonic genes of barrier integrity were significantly upregulated and the genes of hepatic lipid metabolism and that of colonic inflammatory response were suppressed. They attenuated the gut dysbiosis in obese mice, such as the significant enrichment of beneficial genera ( Bifidobacterium and Olsenella ) and suppression of harmful ones ( Mucispirillum and Helicobacter ). Significant enrichment of carbohydrate metabolism associated with the promotion of short-chain fatty acid production and decrease of the metabolisms related to obesity and gut dysbiosis (valine, leucine, and isoleucine biosynthesis, and nitrogen metabolism) were also observed by the administration of ASKP, 60P, and 60S. Overall, these polysaccharides showed potential in acting as prebiotics in preventing high-fat-diet-induced obesity.

The anti-washout ability of calcium phosphate cement (CPC) determines the effectiveness of CPC in clinical application. The γ-ray irradiation method often used in the sterilization process of CPC products is easy to degrade some commonly polymer anti-washout agent, which greatly reduces its anti-washout performance. Artemisia sphaerocephala Krasch gum (ASKG) has the potential of radiation resistance and anti-washout, but no one has considered its performance as anti-washout agent of CPC and mechanism of radiation resistance and anti-washout so far. In this study, we report the effect of γ-ray on ASKG and the effectiveness of ASKG for enhancing of radiation resistance and anti-washout ability of CPC, the physical, chemical properties and in vitro cell behaviors of ASKG-CPCs were also investigated. The results showed that addition of ASKG before and after irradiation could significantly enhanced the anti-washout performance of CPC, which is differ from conventional anti-washout agents. Meanwhile, ASKG-CPCs had an excellent injectable property and biocompatibility, and low content of irradiated ASKG could promote bone differentiation well. We anticipate that the radiation-resistant and anti-washout ASKG-CPCs have potential application prospect in orthopaedic surgery.

This study evaluated the impact of Artemisia sphaerocephala Krasch glucomannan with different degrees of acetyl group substitution (DS) on the prebiotic properties of grape seed proanthocyanidins (GSP). UV spectra, CIELab, and dynamic light scattering analyses indicated DS-influenced variable interactions between GSP and glucomannan. In vitro fermentation demonstrated that glucomannan enhanced the solubility of some phenolic compounds, and decreased the pH value of fermentation liquids. The production of acetate acid and total short chain fatty acids in the GSP fermentation liquid increased with the degree of DS of glucomannan. Notably, acetylated glucomannan exerted dramatic effects on GSP-induced gut microbiota modulation. The relative abundances of Bacteroides ovatus and Bacteroides decreased as DS increased. Meanwhile, Bacteroides acidifaciens and Akkermansia muciniphila have a positive correlation, even though the GSP-promoted enrichment of A. muciniphila was inhibited by the added glucomannan. Moreover, glucomannan enhanced the metabolism of nucleotides, secondary bile acid, and glycan inhibited by GSP. These findings suggest that acetylated glucomannan affect the prebiotic properties of GSP with its DS serving as a key factor.

Artemisia sphaerocephala Krasch polysaccharide (ASKP) and its two fractions—60P (branched xylan) and 60S (branched glucomannan), were subjected to simulated gastrointestinal digestion and in vitro fermentation by human fecal microbiota. The results showed that all polysaccharide fractions could transit through gastrointestinal tract without dramatic degradation and be utilized by gut microbiota. ASKP exhibited the highest depletion rate and highest capability to decrease the pH than its fractions. Meanwhile, 60S showed the stronger capability to increase the production of propionic acid and reduce the ratio of acetic acid to propionic acid. At the phylum level, all polysaccharides efficiently reduced the Firmicutes/Bacteroidetes ratio and relative abundance of Proteobacteria, with ASKP being the most capable to suppress the proliferation of Proteobacteria. At the genus level, ASKP and 60P markedly promoted the growth of Bacteroidetes , and 60S promoted the growth of Parabacteroides and Collinsella . Prediction on metabolic function revealed that polysaccharide administration could dramatically change the metabolic profile of bacteria compared with fructooligosaccharides. Besides, all the polysaccharides dramatically promoted the bile acid metabolism. Compared with 60S, ASKP and 60P showed stronger ability to suppress the metabolisms on carbohydrate and amino acid. In summary, both ASKP and its two fractions showed the prebiotic potentials.

The natural high molecular polysaccharide Artemisia sphaerocephala Krasch gum (ASKG) was introduced into Polyvinyl alcohol (PVA) and Sodium alginate (SA), and the hydrogels with excellent absorbent properties were prepared by crosslinking method. The hydrogel form porous network structures through esterification of CA with PVA and ASKG, and chelation of Ca 2+ and SA. The water absorption, water retention, porosity and thermal stability of hydrogels are improved by ASKG. The higher the concentration and addition of cross-linking agent, the lower the water absorption rate of the hydrogels and the denser pore structure. When PVA is more than SA, the hydrogel has the best mechanical properties, and when SA is more than PVA, the hydrogel has porous network structure. The water absorption kinetics of the hydrogels conform Schott second-order kinetic model, indicating that the water absorption is a simple diffusion behavior. The 5P-5S-6 A-1C-0.025Ca 2+ hydrogel pad effectively adsorb fish fillet exudates, maintain the cleanliness of the fish fillets, inhibit the growth of microorganisms and protein oxidation due to wonderful water absorption, so the shelf life of the fillets is extended from 6.8 days to 9.1 days. Therefore, this study can provide technical guidance and theoretical support for the development of fresh food packaging materials.
