In current study, a water-soluble polysaccharide (GP-I), with a molecular mass of 33 kDa, was purified from Gynostemma pentaphyllum. Gas chromatography (GC) analysis suggested that it was composed of Glc, Gal, Man, Rha and Ara with a ratio of 5.3: 4.2: 3.0: 0.7: 0.8. The GP-I (25, 50, 100, 200 and
Water-soluble polysaccharide from Gynostemma pentaphyllum herb tea (PSGP) was isolated by hot-water extraction and ethanol precipitation. The chemical components and preliminary immunomodulating activity of PSGP were investigated both in vitro and in vivo. Capillary zone electrophoresis analysis
A preparative column chromatographic method for isolation of carotenoids and chlorophylls from Gynostemma pentaphyllum, a traditional Chinese herb, was developed to evaluate their antiproliferative effects on the hepatoma cell Hep3B. An open column containing 70 g of magnesium oxide-diatomaceous
The pharmacological effects of Anoectochilus formosanus, Ganoderma lucidum and Gynostemma pentaphyllum were studied against carrageenan-induced paw edema and CC1(4)-induced hepatotoxicity in rats. The water extracts of G. pentaphyllum and G. lucidum were found to possess significant
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
Many traditional Chinese medicines (TCM), such as Eucommia ulmoides Oliv., Gynostemma pentaphyllum (Thunb.) Makino, and Curcuma longa L., have been reported to have various immune-modulatory effects.
OBJECTIVE
To determine the effects of extracts from these three TCM on type 1 T help
Two novel 20-oxo-21-nordammar-22, 24-diene saponins, 21-norgypenosides A (1) and B (2), were characterized from the aerial parts of tetraploid Jiaogulan ( Gynostemma pentaphyllum ), a popular tea ingredient. Their structures, including the absolute configurations, were comprehensively elucidated by
Gynostemma pentaphyllum is a traditional Chinese medicine reported to possess a wide range of health benefits. As the major component of G. pentaphyllum, gypenoside (GP) displays various anti-inflammatory and anti-oxidant properties. However, it is unclear whether GP can protect against
Saponins, the primary phytochemicals contributing to the health properties of G. pentaphyllum were frequently studied. However, compounds responsible for its bioactivities were still poorly understood. The saponin-rich fraction (GPMS), 3- O-[2G-( E)-Coumaroyl-3G- O-β-d-glucosyl-3R-
The current work aimed to assess whether Gynostemma pentaphyllum (GP), a Chinese herbal medicine, structurally modifies the gut microbiota in rats during non-alcoholic fatty liver disease (NAFLD) treatment.High-fat diet (HFD)-induced NAFLD rats were orally Reducing β amyloid- (Aβ-) induced microglial activation is believed to be effective in treating Alzheimer's disease (AD). Microglia can be activated into classic activated state (M1 state) or alternative activated state (M2 state), and the former is harmful; in contrast, the latter is beneficial.
This study aimed to investigate the effect of single and combination therapy using chitosan (K), gynostemma (J), and motherwort (Y) on an experimental rat model of chronic renal failure (CRF) induced by adenine and the underlying mechanisms. CRF rats were treated with individual or combinational
Vascular cell adhesion molecule-1 (VCAM-1) is involved in several diseases, including chronic inflammation and atherosclerosis. Inhibition of the expression of this adhesion molecule is one of the key targets of anti-inflammatory, anti-cancer and anti-atherosclerotic drugs. Gynostemma pentaphyllum
Gypenosides (Gyps) are triterpenoid saponins contained in an extract from Gynostemma pentaphyllum Makino and reported to induce apoptosis in human hepatoma cells through Ca(2+)-implicated endoplasmic reticulum (ER) stress and mitochondria-dependent pathways. The mechanism underlying the
