General Description

Rhamnose is a naturally occurring sugar that is primarily found in plants, particularly in the cell walls of certain types of seaweed and in the berries of the buckthorn plant. It is a rare sugar that is not as commonly found in nature as other sugars such as glucose and fructose. Rhamnose is also used in the production of certain pharmaceuticals, as it has been found to have anti-inflammatory and antimicrobial properties. Additionally, rhamnose is a key component in the structure of certain bacterial cell walls, making it an important target for researchers studying bacterial infections and antibiotic resistance. Overall, rhamnose plays a crucial role in various biological processes and has potential applications in medicine and biotechnology.

Check Digit Verification of cas no

The CAS Registry Mumber 10485-94-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,4,8 and 5 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 10485-94:
(7*1)+(6*0)+(5*4)+(4*8)+(3*5)+(2*9)+(1*4)=96
96 % 10 = 6
So 10485-94-6 is a valid CAS Registry Number.

Identification of carbohydrate isomers in flavonoid glycosides after hydrolysis by hydrophilic interaction chromatography

Spackova, Vera,Pazourek, Jiri

, p. 357 - 364 (2013)

A method for carbohydrate isomers (saccharide units) identification in flavonoid glycosides after hydrolysis by an HPLC system with two detectors (diode array UV-VIS detector and evaporative light scattering detector) was set up in this work. Experimental procedure was optimized with two types of model glycosides, namely rutin and hesperidin. The model glycosides were hydrolyzed to saccharide units and aglycone parts; the aglycone was characterized by its UV-VIS spectrum and the saccharide unit was identified by its retention time and elution profile (anomeric signals). Acidic and enzymatic hydrolyses were compared in the first step of the method; in acidic hydrolysis, trifluoracetic acid was used, while glucosidase, galactosidase, and hesperidinase were used in enzymatic hydrolysis. A complete enzymatic hydrolysis was achieved with hesperidin and neohesperidin, but not with 3-O-glycosides. The method was applied for the identification of a glycone from a glycoside isolated from Polygonum lapathifolium (Polygonaceae sp.).

Purification, characterization and antitumor activity of polysaccharides extracted from Phellinus igniarius mycelia

Li, Shi-Chao,Yang, Xiao-Ming,Ma, Hai-Le,Yan, Jing-Kun,Guo, Dan-Zhao

, p. 24 - 30 (2015)

Abstract Water-soluble intracellular polysaccharides (IPS) were extracted from cultured mycelia of Phellinus igniarius. The IPS were purified by ethanol fractional precipitation, ion-exchange and size exclusion chromatography in that order. Homogeneous polysaccharide IPSW-1, IPSW-2, IPSW-3, and IPSW-4 were obtained, which molecular characteristics were examined using multiangle laser-light scattering and refractive index detector system. The average molecular weights of them were 34.1, 17.7, 15.1, 21.7 kDa, respectively. GC analysis indicated that IPSW-1, IPSW-2 and IPSW-3 all only contained glucose, while IPSW-4 was composed of rhamnose, xylose, mannose, glucose and galactose in a molar ratio of 1.29:1.21:1:43.86:1.86. UV and IR analysis suggested they belonged to α-type of the pyran group and didn't contain protein. These homogeneous polysaccharides could inhibit the growth of SW480 and HepG2 cells to a certain extent in a dose-dependent manner. So they could be beneficial for the further development of a natural carcinoma preventive agent and functional food.

Novel polysaccharide from Chaenomeles speciosa seeds: Structural characterization, α-amylase and α-glucosidase inhibitory activity evaluation

Deng, Yejun,Huang, Lixin,Zhang, Caihong,Xie, Pujun,Cheng, Jiang,Wang, Xiang,Liu, Lujie

, p. 755 - 766 (2020)

Purification and structural characterization of a novel polysaccharide fraction from Chaenomeles speciosa seeds were investigated. After hot water extraction and ethanol precipitation, the crude polysaccharide was sequentially purified with Cellulose DEAE-52 and gel-filtration chromatography, and a highly purified polysaccharide fraction (F3) was obtained. The structure of F3 was characterized by high-performance gel permeation chromatography (HPGPC), high performance liquid chromatography (HPLC), ultraviolet-visible (UV), Fourier transform infrared (FT-IR) and nuclear magnetic resonance (NMR) spectrum, together with methylation, scanning electron microscopy (SEM), atomic force microscope (AFM), and Congo-red test analysis. The results indicated that F3 was a homogeneous polysaccharide fraction with a molecular weight of 8.65 × 106 Da, and it was composed of Rha, GlcA, Gal, and Ara in a molar ratio of 6.34:5.73:47.14:40.13. The backbone of F3 was consisted of →3,6)-Galp-(1→, and the side chains of F3 were composed of Araf-(1→, →4)-GlcpA-(1→, →4)-Galp-(1→ and →3)-Rhap-(1→. The hypoglycemic assays demonstrated F3 had good α-amylase and α-glucosidase inhibition activities, and their IC50 values were 6.24 mg/mL and 4.59 mg/mL respectively. Thus, the polysaccharide from Chaenomeles speciose could be applied as a potential natural source in retarding postprandial hyperglycemia effects.

Epi-α-bisabolol 6-deoxy-β-d-gulopyranoside from the glandular trichome exudate of Brillantaisia owariensis

Asai, Teigo,Hirayama, Yui,Fujimoto, Yoshinori

, p. 376 - 378 (2012)

A new sesquiterpene glycoside, (-)-epi-α-bisabolol 6-deoxy-β-d-gulopyranodide (1), has been isolated from the glandular trichome exudate of Brillantaisia owariensis (Acanthaceae). The structure of compound 1 was determined by spectroscopic analysis as well as acidic hydrolysis of 1 leading to (-)-epi-α-bisabolol (2) and 6-deoxy-d-gulose (3). This is the first study to analyze secondary metabolites from glandular trichome exudates of plants belonging to the Acanthaceae family. 6-Deoxygulopyranoside is the first example of an epi-α-bisabolol glycoside of plant origin.

A novel low-molecular-mass pumpkin polysaccharide: Structural characterization, antioxidant activity, and hypoglycemic potential

Huang, Linlin,Li, Fei,Li, Quanhong,Liang, Li,Wei, Yunlu,Yu, Guoyong

, (2020/10/02)

The novel natural low-molecular-mass polysaccharide (SLWPP-3) from pumpkin (Cucurbia moschata) was separated from the waste supernatant after macromolecular polysaccharide production and purified using a DEAE cellulose-52 column and gel-filtration chromatography. Chemical and instrumental studies revealed that SLWPP-3 with a molecular mass of 3.5 kDa was composed of rhamnose, glucose, arabinose, galactose and uronic acid with a weight ratio of 1: 1: 4: 6: 15, and primarily contained →3,6)-β-D-Galp-(1→, →4)-α-GalpA-(1→(OMe), →4)-α-GalpA-(1→, →2,4)-α-D-Rhap-(1→, →3)-β-D-Galp-(1→, →4)-α-D-Glcp, and →4)-β-D-Galp residues in the backbone. The branch chain passes were connected to the main chain through the O-4 atom of glucose and O-3 atom of arabinose. Physiologically, the ability of SLWPP-3 to inhibit carbohydrate-digesting enzymes and DPPH and ABTS radicals, as well as protect pancreatic β cells from oxidative damage by decreasing MDA levels and increasing SOD activities, was confirmed. The findings elucidated the structural types of pumpkin polysaccharides and revealed a potential adjuvant natural product with hypoglycemic effects.
