چکیده
The absolute stereochemistry of blumenol C glucoside and byzantionoside B was revised here as (6R,9S)- and (6R,9R)-9-hydroxymegastigman-4-en-3-one 9-O-beta-D-glucopyranosides, respectively, by modified Mosher's method. The empirical rules of (13)C-NMR chemical shift to determine the absolute stereochemistry of C-9 of 9-hydroxymegastigmane 9-O-beta-D-glucopyranoside were also discussed.

Identification of minor secondary metabolites from the latex of Croton lechleri (Muell-Arg) and evaluation of their antioxidant activity.
Dragon's blood (Sangre de drago), a viscous red sap derived from Croton lechleri Muell-Arg (Euphorbiaceae), is extensively used by indigenous cultures of the Amazonian basin for its wound healing properties. The aim of this study was to identify the minor secondary metabolites and test the antioxidant activity of this sustance. A bioguided fractionation of the n-hexane, chloroform, n-butanol, a...
متن کاملNeonaucline, a new indole alkaloid from the leaves of Ochreinauclea maingayii (Hook. f.) Ridsd. (Rubiaceae).
A new indole alkaloid; neonaucline (1), along with six known compounds-Cadamine (2), naucledine (3), harmane, benzamide, cinnamide and blumenol A-were isolated from the leaves of Ochreinauclea maingayii (Rubiaceae). In addition to that of compound 1, (13)C-NMR data of cadamine (2) and naucledine (3) were also reported. Structural elucidations of these alkaloids were performed using spectroscopi...
متن کاملQuantum Chemical Investigations on C14C10-Branched-Chain Glucoside Isomers Towards Understanding Self-Assembly
Density Functional Theory (DFT) calculations have been carried out using a Polarizable Continuum Model (PCM) in an attempt to investigate the electro-molecular properties of branched-chain glucoside (C14C10-D-glucoside) isomers. The results showed that αconfiguration of pyranoside form is thermodynamically the most stable, while the solution should contain much more β...
متن کاملMegastigmane and iridoid glucosides from Clerodendrum inerme.
From the aerial parts of Clerodendrum inerme, two megastigmane glucosides (sammangaosides A and B) and a iridoid glucoside (sammangaoside C) were isolated together with 15 known compounds. The structural elucidations were based on analyses of physical and spectroscopic data.
متن کاملA Study on the Electronic and Structural Properties of C12X8 (X = C, B) and Their Interaction with Glycine with Potentially Drug Delivery Vessels
In this paper, the structural properties of C20 and C12B8 fullerene interacting with glycine based onthree active sites of glycine and one C atom or one B atom in C12B8 were analyzed through thedensity functional theory. It was found out that the binding of glycine to C12B8 generated a complex.Our results were extremely relevant in order to identify the potential applications of functionalizedC...
