Due to environmental concerns and multifunctional requirements, natural additives are a promising alternative traditional enhancers like metal nanoparticles. Lanzhou lily crude extract (LLCE) was investigated as an additive in PEG400 base oil. Firstly, different contents of LLCE notably improved physiochemical properties, such thermal stability, viscosity, the viscosity index. With 5–10 wt.% added PEG400, degradation temperature increased by 37.3–49.5 °C. Secondly, addition significantly...
Codonopilate A (1), a triterpenyl ester, was isolated from monocultivated soil of annual Codonopsis pilosula and identified as the main autotoxin. The yield ratio codonopilate in dried calculated 2.04 μg/g. Other two triterpenoids, taraxeryl acetate (2) 24-methylenecycloartanol (3), were well showing weaker autotoxity. This first time that potential allelochemicals autotoxins cultivated reported. Accumulation reactive oxygen species (ROS) induced by root tips considered an important factor...
Allelochemicals are the media of allelopathy and form chemical bases plant-environment interactions. To determine true allelochemicals their autotoxic effects, seven compounds were isolated identified from in-situ sampled rhizosphere soil cultivated Saussurea lappa. Of these; costunolide (2), dehydrocostus lactone (3) scopoletin (4) showed significant inhibition on seedling growth in a concentration-dependent manner. Detection observation demonstrated that antioxidase system was found to be...
Long-term heat stress (HS) severely restricts the growth performance of beef cattle and causes various health problems. The gut microbiota plays a crucial role in HS-associated inflammation immune involving lymphocyte function. This study investigated effects dietary tea polysaccharide (TPS), natural acidic glycoprotein, on HS-induced anorexia, inflammation, dysbiosis Simmental cattle.
The objective of this study was to investigate the regulatory effects a high-fiber content feed on productive performance, meat quality, and fat acid composition. A total 18 120-day-old Yushan pigs with similar initial body weight were randomly allotted into high-concentrate diet (high energy, HE) (low LE) treatments for determination fatty content. Further, blood metabolomic, gut microbiota, liver energy-related gene expression measurements used underlying mechanisms. Results showed that LE...
Abstract Variations in snow cover (as specific precipitation) can have an important effect on development of biological soil crusts (BSCs) arid and semiarid regions, where water is the principal limiting factor for microorganisms. However, there still limited knowledge available regarding effects snowfall properties microbial biomass BSCs. To examine these cover, three types BSCs (cyanobacteria‐dominated, lichen‐dominated, moss‐dominated crusts) were collected exposed to five depths 3 years....
Natural pesticides are the subject of growing interest, as overuse synthetic severely threatens safety humans and eco-environment. Allelopathic plants can release plentiful secondary metabolites natural plant growth regulators to affect neighboring plants. Bio-guided isolation aerial waste part typical allelopathic plant-Codonopsis pilosula led six active compounds being produced, including ginsenoside Rg1 (1), Re (2), luteolin (3), luteolin-5-O-glucoside (4), Rb1 (5) lobetyolin (6)....
Water is a major limiting factor for plant growth in arid and semi-arid regions. To find out the main sources of water two artificial sand-fixation plants (Caragana korshinskii Artemisia ordosica), we analyzed characteristics hydrogen oxygen stable isotopes molecules rainfall, soil xylem water. analyze these plants, used direct comparison method multi-variate mixed linear model. The results showed that an equation local meteoric line Shapotou was δD=7.83δ18O+5.64 (R2=0.91). value rainfall...
Due to environmental concern and multifunctional requirement, natural additive is a promising alternative compared traditional enhancer like metal nanoparticles, etc. In this work, Lanzhou lily crude extract (LLCE) reportedly lubricant under extreme pressure condition was investigated as in PEG400 base oil. Firstly, different content of LLCE notably improved physiochemical property thermal stability, viscosity index. By 5 %-10 % added PEG400, the degradation temperature raised by 37.3-49.5...
An improved QuEChERS method combined with Multi-Plug Filtration Cleanup clean-up procedure was developed for the simultaneous determination of 16 different sulfonamides in forage grass using UHPLC-MS/MS.
