2,3,4-tri-O-methyl-D-xylose is a chemical compound derived from D-xylose, a naturally occurring pentose sugar. In 2,3,4-tri-O-methyl-D-xylose, three hydroxyl groups (-OH) at the 2nd, 3rd, and 4th carbon positions of the xylose molecule are replaced by methoxy groups (-OCH3), resulting in a methylated derivative. This modification can alter the chemical properties and reactivity of the original sugar, making it useful in various applications such as organic synthesis, pharmaceuticals, and as a research tool in studying carbohydrate chemistry. The compound is typically synthesized through a series of chemical reactions, including protection of the hydroxyl groups with methyl groups to prevent unwanted side reactions during subsequent steps.

Check Digit Verification of cas no

The CAS Registry Mumber 4060-04-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,6 and 0 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4060-04:
(6*4)+(5*0)+(4*6)+(3*0)+(2*0)+(1*4)=52
52 % 10 = 2
So 4060-04-2 is a valid CAS Registry Number.

Structure characterization of polysaccharide isolated from the fruiting bodies of Tricholoma matsutake

Ding, Xiang,Feng, Su,Cao, Mei,Li, Mao-tao,Tang, Jie,Guo, Chun-xiao,Zhang, Jie,Sun, Qun,Yang, Zhi-rong,Zhao, Jian

, p. 942 - 947 (2010)

A novel heteropolysaccharide was isolated from the fruiting bodies of Tricholoma matsutake through DEAE-cellulose column and Sephadex G-100 column. The T. matsutake polysaccharide (TMP-A) had a molecular weight of 8.89 × 104 Da and was mainly composed of 4-D-Glc:4,6-D-Glc:3-D-Gal:T-D-Xyl and with the ratio of 7:1:1:1. The structural features of TMP-A were investigated by a combination of total hydrolysis, methylation analysis, gas chromatography-mass spectrometry (GC-MS), scanning electron microscope (SEM), infrared (IR) spectra, nuclear magnetic resonance (NMR) spectroscopy and dynamical analysis of the atomic force microscope (AFM) studies. The results indicated that TMP-A had a backbone of 1,4-β-glucopyranos which branches at O-6 composed of an (1 → 3)-α-galactopyranose residue and terminated with α-xylopyranose residue. Chain conformation study showed that the polysaccharide took random coil compact conformation.

Allelopathic effect of triterpenoid saponins from the stems of lathyrus aphaca linn

Yadava, Raj N.,Asati, Nidhi

, p. 177 - 184 (2018/09/14)

Two new triterpenoid saponins have been isolated from the methanolic extract of the stems of the Lathyrus aphaca Linn. A new compound 1 has m.p. 295?297°C, m.f. C47H78O16, [M]+ m/z 898 was characterized as 3-O-[β-D-galactopyranosyl-(14)]-β-D-xylopyranosyl-3β,11α,28-trihydroxy-olean-12-ene-28-O-α-L-rhamnopyranoside and compound 2 has m. p. 289-291°C, m.f. C46H76O16, [M]+ m/z 884 was characterized as 3-O-[β-D-xylopyranosyl-(1→4)]-β-D-glucopyranosyl-(1→4) α-L-arabinofuranosyl 2α,3β,19α-trihydroxy-olean-12-ene by various color reactions, chemical degradations, and spectral analysis. From experimental findings, it was concluded that both compounds 1 and 2 have shown allelopathic effects on the growth of shoot length of the seeds of Zea mays (L.).

Yadava,Vishwakarma, Umesh Kumar

, p. 953 - 957 (2013/08/15)

A new bioactive allelochemical 1, m.p. 235-36°C, m.f. C 34H42O20, [M]+ 770 (FABMS), has been isolated from methanolic extract of the seeds of Cassia absus Linn, alongwith two known compounds 3, 5, 7, 4-tetrahydroxy-2 5'-dimethoxy flavone and Luteolin. The structure of a new compound has been characterized as 5, 7, 4-trihydroxy-8,3'-dimethoxyflavone-5-O-a- L-rhamnopyranosyl-7-O-β-D- xylopyranosyl-( I -4)O-β-D-galacto- pyranoside by various colour reactions, spectral analysis and chemical degradations. All the secondary plant metabolites are called allelochemicals.

Two antifungal active triterpenoid saponins from the seeds of Lathyrus plants

Khan, Noor Afshan

experimental part, p. 1687 - 1694 (2012/01/14)

Two novel triterpenoid glycosides have been isolated from butanolic seeds extract of two varieties of Lathyrus plants, i.e. Lathyrus ratan and Lathyrus aphaca. Their structures were elucidated as 3-O-[β-D-glucuronopyranosyl- (1→4)-α-L-arabinopyranosyl-(1→2)-α-L-arabinopyranosyl] -olean-11,13 (18)-dien-28-oic acid (1) and 3-O-{β-D-xylopyranosyl-(1 → 2)-β-D-glcopyranosyl-(1→4)-[β-D-glucopyranosyl-(1→2)]- α-D-xylopyranosyl}-2, 16-dihydroxy-4-hydroxymethyl urs-12-en-28-oic acid (2) on the basis of spectral evidences, i.e. FTIR, 1H-NMR, 13C-NMR, ESI-MS and FAB-MS data. The isolated saponins were tested for their antifungal activity. Compound 1 showed maximum inhibition against Colletotrichum dematium (77.8%), whereas compound 2 showed maximum inhibition against Alternaria alternata (53.9%).
