The leaves of Garcinia epunctata Stapf have furnished two new phenolic glucosides, epunctosides A and B, along with 13 known secondary metabolites identified as lanceoloside A, betulinic acid, lupeol, stigmasterol, β-sitosterol, β-sitosterol-3-O-β-d-glucopyranoside, stigmasterol-3-O-β-d-glucopyranoside, luteolin-7-O-glucoside, quercitin-7-O-glucoside, amentoflavone, robustaflavone, 4'-O-methyl-amentoflavone and 4'-O-methyl-robustaflavone. All structures were established from chemical and spectroscopic evidence including 1D and 2D NMR data as well as by comparing the obtained spectroscopic data with literature. This is the first report of the presence of phenolic glucosides in the genus Garcinia.

Bioactive compounds demonstrating antioxidant activity were analyzed in berries and leaves of nine cultivars of sea buckthorn (Hippophaë rhamnoides L.) of various ripening times. Total polyphenols we...
ROS and subsequent oxidative stress are reported to play important roles in chronic metabolic diseases. Plant-derived polyphenols, especially food-derived phenolics, have attracted a lot of attention ...
Five new metabolites, including two monoterpene glycosides Pubescenosides L-M (1-2) and three phenolic glycosides, Pubescenosides N-P (3-5), along with nineteen known ones, including liganoids, hemite...
Although phenylethanoid glycosides (PhGs) occur widely in plants, their characterisation by liquid chromatography/mass spectrometry (LC/MS) is less well studied than other phenolic glycosides such as ...
Sea buckthorn (Elaeagnus rhamnoides (L.) A. Nelson) is a shrub with lanceolate leaves and orange fruits. In traditional Chinese medicine, sea buckthorn organs, especially fruits have been used to trea...
Treatments are an administration of a mixed extract of Garcinia mangostana 400mg and Solanum Lycopersicum Fructus 200mg (OKSI(R) POM TR 193324351) and placebo control.
The study's main objective is to investigate the effects of acute consumption of a preparation containing 100 mg of a specific phenolic compound (patent pending, P201531587) on systolic BP...
Obesity is one of the greatest public health challenges of the 21st century. Its prevalence has tripled in many countries of the European Region since the 1980s, and the numbers of those a...
An acute, randomized, placebo controlled, double blinded crossover study in health subjects. Participants will complete 4 intervention arms in random order consisting of a placebo control ...
A diet rich in whole grain is inversely associated with cardiovascular disease risk and this benefit could be partly attributed to the phenolic acid content of whole grains. The exact abso...
A plant genus of the family OLEACEAE. Oleuropein, a phenolic secoiridoid glycoside, is found in the leaves.
Glycosides from plants of the genus DIGITALIS. Some of these are useful as cardiotonic and anti-arrhythmia agents. Included also are semi-synthetic derivatives of the naturally occurring glycosides. The term has sometimes been used more broadly to include all CARDIAC GLYCOSIDES, but here is restricted to those related to Digitalis.
Any compound that contains a constituent sugar, in which the hydroxyl group attached to the first carbon is substituted by an alcoholic, phenolic, or other group. They are named specifically for the sugar contained, such as glucoside (glucose), pentoside (pentose), fructoside (fructose), etc. Upon hydrolysis, a sugar and nonsugar component (aglycone) are formed. (From Dorland, 28th ed; From Miall's Dictionary of Chemistry, 5th ed)
A number of different cardioactive glycosides obtained from Strophanthus species. OUABAIN is from S. gratus and CYMARINE from S. kombe. They are used like the digitalis glycosides.
A plant genus of the family VALERIANACEAE. Members contain ursolic acid and oleanolic acid glycosides, sulfapatrinosides (triterpenoid glycosides), and patriscabrol (iridolactone).
