Abstract In order to clarify the mechanism involved in antiinflammatory activity of atractylenolide I and III from rhizomes Atractylodes macrocephala Koidz, their effects on tumor necrosis factor‐ α (TNF‐ ) nitric oxide (NO) production peritoneal macrophages were examined. Atractylenolide decreased TNF‐ level LPS‐stimulated a dose‐dependent manner, IC 50 values 23.1 µ m 56.3 , respectively. RT‐PCR analysis indicated that they inhibited mRNA expression. Furthermore, NO LPS‐activated...
This study aimed to extract and separate total anthocyanins from <italic>Lycium ruthenicum</italic> Murr. by combining deep eutectic solvents (DES) with macroporous resin chromatography develop green analytical methods for the determination of anthocyanins.
Abstract The aim of this study was to extract and purify anthocyanins from Lycium ruthenicum Murr. evaluate their tyrosinase inhibitory activity. Response surface methodology devoted optimize enzyme‐assisted extraction L. dried fruits. Extraction at 38 °C for 37 min using water‐containing pectinase (52.04 mg/100 g fruit) rendered an anthocyanin yield 19.51 ± 0.21 mg/g. purified were separated the by macroporous resin XDA‐6. Antioxidant tests in vitro suggested that exhibited a potent...
No simple methods are used for the quantitative analysis of protease activity in colored food up till now. Thus, this study aims to establish a new and method detection activity, especially food. The accuracy, limit, repeatability casein plate were analyzed. Then, application sample recovery was further evaluated. results showed that has high precision, low limit. recoveries eight kinds samples range 92.26–97.84%, relative standard deviation (RSD) 3.56–10.88%. exhibited accuracy. This...
Collagen-induced arthritis (CIA) has traditionally been performed in MHC class II A(q)-expressing mice, whereas most genetically modified mice are on the C57BL/6 background (expressing b haplotype of major histocompatibility complex (MHC) region). However, develop after immunisation with chicken-derived collagen type (CII), but susceptibility variable, and immune specificity not clarified.To establish a CIA model more predictable defined response to CII.Both chicken rat CII were...
Estrogen deficiency is one of the major causes osteoporosis in postmenopausal women. Drynariae Rhizoma a widely used traditional Chinese medicine for treatment bone diseases. In this study, we investigated therapeutic effects total flavonoids (DRTF) on estrogen deficiency-induced loss using an ovariectomized rat model and osteoblast-like MC3T3-E1 cells. Our results indicated that DRTF produced osteo-protective rats terms reduction, including decreased levels turnover markers, enhanced...
Drynariae Rhizoma is a kidney-tonifying herb that has long history in clinical practice for the treatment of bone fractures and joint diseases China. Flavonoids are considered to be its major active ingredients reported ease loss ovariectomized rats. However, beneficial effects total flavonoids on osteoporosis caused by microgravity or mechanical inactivity remain unknown. This study assessed (DRTF, Qihuang, Beijing, China, national medicine permit No. Z20030007, number production: 04080081,...
A producing-fibrinolytic enzyme strain was isolated with high yield. The identified as Bacillus amyloliquefaciens. B. amyloliquefaciens GUTU06 fibrinolytic purified by acetone precipitation and reverse micelle. Acetone condition micelle were examined. Results showed that the total extraction efficiency 64.49 % ± 1.6 %. purification fold of entire process reached 13.38. optimum pH is 5, temperature 45 °C. Fe3+ K+ can enhance activity enzyme. Compared to commercial enzymes such urokinase...
This study delved into the feasibility of fermenting Rosa roxburghii Tratt and coix seed beverage (RRTCSB) using dual-strain fermentation. The impact Trametes versicolor Lactiplantibacillus plantarum LB12 fermentation on RRTCSB's physicochemical properties was investigated. Post-fermentation, beverage's color clarified brightened, displaying an appealing hue. Even concentrated malic acid, which contributes both sourness astringency, decreased from 21.227 ± 0.151 mg/mL before to 14.067 0.090...
This study investigated the bacterial community and volatile components of Guizhou Niuganba (GZNGB), a traditional fermented food Southwest China. Microbiological analysis GZNGB based on Illumina MiSeq sequencing technology revealed that Firmicutes (61.97%) unclassified_Bacteria (25.35%) were predominant phyla Staphylococcus (41.58%), (25.35%), Lactobacillus (13.89%), Streptophyta (9.2%) genera. Additionally, 96 compounds, including hydrocarbons (34.37%), alcohol (21.87%), aldehyde (9.38%),...
Background. Licorice is one of the most ubiquitous herbs in traditional Chinese medicine, with notable anti-inflammatory and antiulcerative effects as well potent digestive disease therapeutic impacts; yet, its active components mechanisms remain unclear. There a lot evidence that Glycyrrhiza polysaccharide (GPS) has antioxidants, improving intestinal flora, effects, etc. Hypothesis/Purpose. Here, we investigated GPS on dextran sulfate sodium (DSS)-induced acute ulcerative colitis (UC) mice...
Fortifying yogurt with blueberries, potatoes, and Perilla seed oil (PO) can enhance the yogurt's nutritional health-promoting effects. This study aimed to evaluate development of volatile compounds, physicochemical quality, amino acids, shelf life flavored supplemented PO. Results revealed that adding PO changed flavor composition free acid content. The essential increased 0.346 times by Moreover, addition significant differences (P < 0.05) in sensory scores, fat, acidity, color, syneresis,...
