Morindae officinalis radix (MOR) is a famous Chinese herbal medicine which has long history of use in medicine and food. MOR and MOR with steaming process (PMOR) are the most commonly used forms in clin. and health care. In order to establish a fast and mostly nondestructive quality control method for MOR, 183 beaches of MOR samples and 20 beaches of PMOR samples were collected com. from major producing areas in Guangdong, Fujian and Guangxi Provinces of China. To predict main components of MOR, a calibration model was established based on near-IR spectroscopy with partial least square regression. The model was optimized by compared the parameters of root mean square error of prediction (RMSEP), root mean square error of cross validation (RMSECV), coefficient of correlation (R²) and ratio of performance to deviation (RPD). Comparative studies were performed to evaluate the performance of models by different spectra preprocessing methods and different data set. The results showed that the model performance was improved with standard normal variate spectra preprocessing methods and when the data set contained both MOR and PMOR samples. A few PMOR samples were added to MOR samples data set the model predictive performance could be improved. The contents of 14 components were predicted in MOR with lower RMSEP and RMSECV, and higher R² and RPD, including fructose (12.8 mg/g, 16.3 mg/g, 0.9873, 10.10), glucose (7.28 mg/g, 8.73 mg/g, 0.9611, 6.21) sucrose (9.24 mg/g, 9.10 mg/g, 0.8419, 1.75), GF2(9.42 mg/g, 11.3 mg/g, 0.8526, 2.03), GF3(7.98 mg/g, 9.20 mg/g, 0.8756, 2.74), GF4(6.81 mg/g, 8.93 mg/g, 0.8663, 3.06), GF5(8.13 mg/g, 8.85 mg/g, 0.9001, 3.06), GF6(6.40 mg/g, 6.95 mg/g, 0.9145, 3.27), GF7(5.53 mg/g, 6.15 mg/g, 0.9195, 3.57), GF8(5.40 mg/g, 6.02 mg/g, 0.9179, 3.31), GF9(3.00 mg/g,4.35 mg/g,0.9446, 5.03),GF10(4.08 mg/g, 5.34 mg/g, 0.8983, 3.62), GF11(8.97 mg/g, 7.70 mg/g, 0.8683, 2.01) and iridoid glycosides (4.12 mg/g, 5.51 mg/g, 0.8712, 2.43). The model established in this paper could predict 14 components of MOR. The results would provide a reference method for the quality control of Chinese medical materials and their process products.

THF (Tetrahydrofuran) is a stable compound with relatively low boiling point and excellent solvency. THF can also be synthesized by catalytic hydrogenation of furan. This allows certain sugars to be converted to THF via acid-catalyzed digestion to furfural and decarbonylation to furan, although this method is not widely practiced. THF is thus derivable from renewable resources.Related Products of 470-69-9

Enzymic glycosylation is an efficient way to increase the water solubility and the bioavailability of flavonoids. Levansucrases from Bacillus subtilis (Bs_SacB), Gluconacetobacter diazotrophicus (Gd_LsdA), Leuconostoc mesenteroides (Lm_LevS) and Zymomonas mobilis (Zm_LevU) were screened for puerarin (daidzein-8-C-glucoside) fructosylation. Gd_LsdA transferred the fructosyl unit of sucrose onto the glucosyl unit of the acceptor forming β-D-fructofuranosyl-(2→6)-puerarin (P1a), while Bs_SacB, Lm_LevS and Zm_LevU synthesized puerarin-4′-O-β-D-fructofuranoside (P1b) and traces of P1a. The Gd_LsdA product P1a was purified and assayed as precursor for the synthesis of puerarin polyfructosides (PPFs). Bs_SacB elongated P1a more competently forming a linear series of water-soluble PPFs reaching at least 21 fructosyl units, as characterized by HPLC-UV-MS, HPSEC and MALDI-TOF-MS. Simultaneous or sequential Gd_LsdA/Bs_SacB reactions yielded PPFs directly from puerarin with the acceptor conversion ranging 82-92 %. The bi-enzymic cascade synthesis of PPFs in the same reactor avoided the isolation of the intermediate product P1a and it is appropriate for use at industrial scale. In the experiment, the researchers used many compounds, for example, (2R,3R,4S,5S,6R)-2-(((2S,3S,4S,5R)-2-((((2R,3S,4S,5R)-3,4-Dihydroxy-2,5-bis(hydroxymethyl)tetrahydrofuran-2-yl)oxy)methyl)-3,4-dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (cas: 470-69-9SDS of cas: 470-69-9).

Structure-function analysis of silkworm sucrose hydrolase uncovers the mechanism of substrate specificity in GH13 subfamily 17 exo-α-glucosidases was written by Miyazaki, Takatsugu;Park, Enoch Y.. And the article was included in Journal of Biological Chemistry in 2020.Computed Properties of C18H32O16 This article mentions the following:

The domestic silkworm Bombyx mori expresses two sucrose-hydrolyzing enzymes, BmSUH and BmSUC1, belonging to glycoside hydrolase family 13 subfamily 17 (GH13_17) and GH32, resp. BmSUH has little activity on maltooligosaccharides, whereas other insect GH13_17 α-glucosidases are active on sucrose and maltooligosaccharides. Little is currently known about the structural mechanisms and substrate specificity of GH13_17 enzymes. In this study, we examined the crystal structures of BmSUH without ligands; in complexes with substrates, products, and inhibitors; and complexed with its covalent intermediate at 1.60-1.85 Å resolutions These structures revealed that the conformations of amino acid residues around subsite -1 are notably different at each step of the hydrolytic reaction. Such changes have not been previously reported among GH13 enzymes, including exo- and endo-acting hydrolases, such as α-glucosidases and α-amylases. Amino acid residues at subsite +1 are not conserved in BmSUH and other GH13_17 α-glucosidases, but subsite -1 residues are absolutely conserved. Substitutions in three subsite +1 residues, Gln191, Tyr251, and Glu440, decreased sucrose hydrolysis and increased maltase activity of BmSUH, indicating that these residues are key for determining its substrate specificity. These results provide detailed insights into structure-function relationships in GH13 enzymes and into the mol. evolution of insect GH13_17 α-glucosidases. In the experiment, the researchers used many compounds, for example, (2R,3R,4S,5S,6R)-2-(((2S,3S,4S,5R)-2-((((2R,3S,4S,5R)-3,4-Dihydroxy-2,5-bis(hydroxymethyl)tetrahydrofuran-2-yl)oxy)methyl)-3,4-dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (cas: 470-69-9Computed Properties of C18H32O16).

Inulin-type fructooligosaccharides (FOS) purified from Morinda Officinalis, with ds.p. (DP) from 3 to 9, have been approved in China as an oral prescribed drug for mild and moderate depression episode, while the stability and oral absorption of this FOS mixtures are largely unknown. As the main active component and quality control marker for above FOS, DP5 was selected as the representative FOS in this study. Desalting method by ion exchange resin was developed to treat bio-sample, followed by separation and quantification by high performance liquid chromatog.-charged aerosol detector. Results showed that the DP5 was stepwisely hydrolyzed in simulated gastric fluid and gut microbiota, while maintained stable in intestinal fluid. DP5 has poor permeability across Caco-2 monolayer with P_app of 5.22 × 10^-7 cm/s, and very poor oral absorption with bioavailability of (0.50 ± 0.12)% in rat. In conclusion, FOS in Morinda Officinalis demonstrated poor chem. stability in simulated gastric fluid and human gut microbiota, and low oral absorption in rats.

A fructan exohydrolase from maize degrades both inulin and levan and co-exists with 1-kestotriose in maize was written by Wu, Silin;Greiner, Steffen;Ma, Chongjian;Zhong, Jiaxin;Huang, Xiaojia;Rausch, Thomas;Zhao, Hongbo. And the article was included in International Journal of Molecular Sciences in 2021.Synthetic Route of C18H32O16 This article mentions the following:

Enzymes with fructan exohydrolase (FEH) activity are present not only in fructan-synthesizing species but also in non-fructan plants. This has led to speculation about their functions in non-fructan species. Here, a cell wall invertase-related Zm-6&1-FEH2 with no ‘classical’ invertase motif was identified in maize. Following heterologous expression in Pichia pastoris and in Nicotiana benthamiana leaves, the enzyme activity of recombinant Zm-6&1-FEH2 displays substrate specificity with respect to inulin and levan. Subcellular localization showed Zm-6&1-FEH2 exclusively localized in the apoplast, and its expression profile was strongly dependent on plant development and in response to drought and abscisic acid. Furthermore, formation of 1-kestotriose, an oligofructan, was detected in vivo and in vitro and could be hydrolyzed by Zm-6&1-FEH2. In summary, these results support that Zm-6&1-FEH2 enzyme from maize can degrade both inulin-type and levan-type fructans, and the implications of the co-existence of Zm-6&1-FEH2 and 1-kestotriose are discussed.

Fructo-oligosaccharides (FOS) are low-calorie sweeteners that can be synthesized by the transfructosylation of sucrose using enzymes known as fructosyltransferases. However, enzymic conversion is inhibited by the accumulation of glucose as a byproduct, which limits the conversion rate and yield. We therefore developed a semi-continuous production process in an enzyme membrane bioreactor (EMBR) system followed by fermentation with the probiotic bacterium Bacillus coagulans. Filtration experiments were conducted in total recycle mode to evaluate membrane fouling using the resistance-in-series model. We found that fouling was predominantly caused by the accumulation of proteins at the membrane surface, which accounted for 29.6-95.5% of the total filtration resistance depending on the conditions. Using these data, we were able to achieve a stable filtration flux that fulfilled the requirements of the EMBR system by regulating the filtration parameters. The average concentration of total FOS in the products of EMBR reached 270 g·L-1, which was 4.6% higher than the batch process. Subsequently, the crude FOS preparation was treated by fed-batch fermentation with B. coagulans. The monosaccharides in the reaction mix (glucose and fructose) were completely removed, increasing the concentration of FOS to 195.9 g·L-1 and the purity to 96.6%.

Uvaia is a Brazilian native species whose fruit has few studies on the nutritional composition and antioxidant properties. In this study, we evaluated for the first time the proximate composition, mineral content, carbohydrate profile, identification of organic compounds, and determination of antioxidant properties in two fractions of this fruit (edible fraction and seed). Edible fraction showed the highest content of ash, lipids, proteins, total fibers, minerals mainly K and Mg (1557.61 and 124.40 mg 100 g-1, resp.), and carbohydrates such as fructose, sucrose, glucose (123.08; 64.40; and 42.39 mg g-1, resp.), and maltotetraose (G4). From the ESI-LTQ-XL-MS/MS anal., it was possible to identify 22 compounds in the edible fraction and 16 compounds in the uvaia seed, including organic acids, phenolic acids and flavonoids. On the other hand, uvaia seed had the highest content of total phenolics, flavonoids and antioxidant capacity.

However, the detailed pharmacol. activities and clin. efficacy of O. sinensis and C. militaris are still elusive. We aimed to evaluate the different actions of O. sinensis and C. militaris on colitis-associated tumorigenesis in Azoxymethane (AOM)/Dextran Sulfate Sodium (DSS)-treated mice and explore the potential gut microbiota-dependent mechanisms. C57BL/6 mice (Male, 4 wk old) were used to construct the AOM/DSS-induced CAC mice model. The mice were administered with 0.6 mg/g/d O. sinensis or C. militaris for 12 wk. Its worth noting that fecal microbiota transplantation (FMT) and antibiotic treatment were used to investigated the complex interactions between the medicinal fungi, gut microbiota and colonic tumorigenesis. O. sinensis treatment significantly increased the body weight and survival rate, reduced the number of colon tumors, improved the damage of colon epithelial tissue, restored the crypt structure and alleviate the colonic inflammation in AOM/DSS-treated mice. RT-qPCR results indicated that O. sinensis partly regulated the Wnt/β-catenin signaling via alleviating the overexpression of β-catenin, TCF4 and c-Myc genes in adjacent noncancerous tissues. Compared with C. militaris, O. sinensis showed better anti-tumor activity. Gut microbiota anal. revealed that O. sinensis reversed the decline of gut microbiota diversity and the structural disorder induced by AOM/DSS. Spearmans correlation anal. showed that O. sinensis promoted the growth of Parabacteroides goldsteinii and Bifidobacterium pseudolongum PV8-2, which were pos. correlated with the anti-tumor activity and the production of SCFAs. FMT combined with antibiotic treatment showed that horizontal fecal transfer derived from O. sinensis-treated mice improved the intestinal inflammation and alleviated the colitis-associated tumorigenesis, which was consistent with the direct ingestion of O. sinensis. O. sinensis could better attenuate colitis-associated tumorigenesis compared with C. militaris. These effects might be at least partially due to the increased abundance of probiotics, especially P. goldsteinii and B. pseudolongum PV8-2.

Agave bagasse is a fibrous-like material obtained during aguamiel extraction, which is also in contact with indigenous microbiota of agave plant during aguamiel fermentation This plant is a well-known carrier of the prebiotic fructan-type carbohydrates, which have multiple ascribable health benefits. In the present work, the potential of ashen and green agave bagasse as functional ingredients in supplemented cookies was studied. For its application, the chem., functional, properties of agave bagasses and formulated cookies were evaluated, as well as the phys. properties of cookies. Chem. characterization was carried out by the proximate anal. of both bagasses and cookies, besides, the anal. of oligosaccharides was made by thin-layer chromatog. and high-performance anion-exchange chromatog. In the same way, functional properties such as oil holding capacity, organic mol. absorption capacity, swelling capacity, and water holding capacity were analyzed in both agave bagasses and supplemented cookies. Finally, modifications in color and texture due to bagasse addition was studied through an anal. of total color difference and a penetrometric test, resp. In this sense, ashen and green agave bagasses demonstrated chem. and functional properties for use in the food industry, since they increased oil holding capacity of cookies and transferred prebiotic fructooligosaccharides to both agave bagasse formulations, which remain active as a prebiotic ingredient in cookies after in vitro digestion and cookie manufacture, including thermal treatment. Hence, agave bagasse could be considered a valuable alternative for the addition of the nutritionally-relevant dietary fiber in healthier foods.
