The mol-ecule of the title compound, C(6)H(12)O(6), [systematic name: (2R,3S,4R,5R,6R)-6-(hydroxy-meth-yl)oxane-2,3,4,5-tetrol] adopts a (4)C(1) chair conformation with the anomeric hydroxyl group in the equatorial position. All hydroxyl groups act as donors and acceptors in hydrogen bonding and the mol-ecule is involved in ten inter-molecular O-H⋯O inter-actions [O⋯O = 2.672 (5)-2.776 (4) Å] w...

The title compound, C6H12O6, a C-3 position epimer of d-galactose, crystallized from an aqueous solution, was confirmed as β-d-pyran-ose with a (4) C 1 (C1) conformation. In the crystal, O-H⋯O hydrogen bonds between the hy-droxy groups at the C-1 and C-6 positions connect mol-ecules into a tape structure with an R 3 (3)(11) ring motif running along the a-axis direction. The tapes are connected ...

This study aimed to determine phenolic compounds of Artemisia spicigera (family Asteraceae) growing in East-Azarbaijan province of Iran. 20%, 40 % and 60% SPE fractions of methanolic extract of A. spicigera, were subjected to reversed phase preparative HPLC, with the mobile phase consisted of methanol and water. Structural identification of phytochemicals by spectroscopic methods including UV a...

Geodesically isotropic positive definite functions on compact two-point homogeneous spaces of dimension d have series representation as members weighted Lebesgue L1w([−1,1]), where the weight w(x)=wα,β(x)=(1−x)α(1+x)β is one related to Jacobi orthogonal polynomials P(α,β)(x) in [−1,1], and exponents α β are d. We derive some recurrence relations among coefficients representations under differen...

Four new minor diterpene glycosides with a rare α-glucosyl linkage were isolated from a cyclodextrin glycosyltransferase glucosylated stevia extract containing more than 98% steviol glycosides. The new compounds were identified as 13-[(2-O-β-D-glucopyranosyl-3-O-(4-O-α-D-glucopyranosyl)-β-D-glucopyranosyl-β-D-glucopyranosyl)oxy] ent-kaur-16-en-19-oic acid-[(4-O-α-D-glucopyranosyl-β-D-glucopyran...
