Three acid polysaccharides obtained from Gynostemma pentaphyllum (Thunb.) Markino (named as GPA1, GPA2 and GPA3) using combination of water extraction, ion-exchange and gel permeation chromatography were subjected to composition analysis and valuated for the antioxidant activity. The sugar content
The phytochemical investigation of the aerial parts of Gynostemma pentaphyllum led to the isolation of a new flavonol glycoside, gynopentaphylloside (1), along with seven known compounds (2-8). The structure of the new compound was determined on the basis of 1D, 2D NMR and HRESIMS data as well as
OBJECTIVE
To investigate the effects of polysaccharide from Gynostemma pentaphyllum on antioxidant activity in skeletal muscle of mice exercised to exhaustion.
METHODS
Three polysaccharide fractions were obtained from G. pentaphyllum polysaccharide (GPP) and termed GPP1-a, GPP2-b, and GPP3-a. Gas
Anoectochilus formosanus Hay. and Gynostemma pentaphyllum Makino are popular folk medicines that have been used for treating hepatitis, hypertension and cancer in Taiwan. Our previous studies showed that these crude drugs exert antiinflammatory activity and hepatoprotective activity against
BACKGROUND
In order to further develop and utilise Gynostemma pentaphyllum (Thunb.) Makino seeds, a detailed analysis of the characteristics of G. pentaphyllum seed oil (GPSO), including its physico-chemical parameters, fatty acid composition and unsaponifiable matter constituents, has been
This work aimed to determine the antioxidant and anti-inflammatory effects of an anti-diabetic polysaccharide (GPP) extracted from Gynostemma pentaphyllum herb on diabetic mice. In vitro antioxidant assays showed that the DPPH radical, hydroxyl radical, superoxide anion, and ABTS radical scavenging
Backgroup: Superfine grinding (SG) technology has attracted considerable attention in food and medicine researcher fields.
Methods: Polysaccharides in superfine powder of
BACKGROUND
A few bioactivities of constituents from Gynostemma laxum, which has been collected in Vietnam, have been reported until now. There is no report about the effects of constituents from G. laxum although the nuclear factor (erythroid-derived 2)-like 2 (Nrf2)-mediated heme oxygenase-1 (HO-1)
A short period of hypoxia/hypoglycaemia (oxygen and glucose deprivation, OGD) induced by perfusion with O(2)/glucose-free medium caused immediate loss and incomplete restoration of evoked field potentials in the CA1 region of transverse hippocampus slices. OGD-dependent decrease in evoked field
The immunomodulatory and antioxidant activities of crude polysaccharides extracted from Gynostemma pentaphyllum Makino (GPMPP) were investigated. GPMPP was composed of rhamnose, arabinose, xylose, mannose, glucose and galactose in the molar ratio of 1.39:3.76:1.00:1.64:4.98:5.88. In vivo studies
Gynostemma pentaphyllum is a traditional Chinese medicine that has previously been used for the treatment of chronic inflammation, hyperlipidemia and liver disease. Gypenoside (GP), the predominant component of Gynostemma pentaphyllum, exhibits a therapeutic effect on chronic hepatic injury,
A novel polysaccharide (GPP-S), with a molecular mass of 1.2 × 10(6) Da, was isolated from the tetraploid Gynostemma pentaphyllum Makino by alkali extraction followed by purifications using DEAE and Sephacryl S-400 column chromatographies. The monosaccharide composition of GPP-S was determined as
Fluorescent carbon dots (CDs) have been synthesized via the calcination method using natural gynostemma as the precursor, without any toxic ingredients or surface passivation chemicals. CDs have a narrow size distribution, and the mean particle size is about 2.5 nm. CDs exhibit good water
Background. The objective of this paper is to demonstrate the effect of Gynostemma pentaphyllum extract on mouse dermal fibroblasts. Recent studies have shown that this plant may possess great antioxidant properties, which can be very beneficial in combating oxidative stress. Methods. Gynostemma
Gynostemma pentaphyllum has been widely used as a traditional herb for its antioxidant and immunostimulatory activities. We have previously reported several useful dammarane-type saponins with cytotoxicity against A549 human lung cancer cells from heat-processed G. pentaphyllum. In this study, a new
