Characterization of ginseng saponin ginsenoside-Rg(3) inhibition of catecholamine secretion in bovine adrenal chromaffin cells.

Numai utilizatorii înregistrați pot traduce articole

Since ginsenoside-Rg(3), one of the panaxadiol saponins isolated from the ginseng root, significantly inhibited the secretion of catecholamines from bovine adrenal chromaffin cells stimulated by acetylcholine (ACh), the properties of ginsenoside-Rg(3) inhibition were investigated. Although

Optimization of the enzymatic production of 20(S)-ginsenoside Rg(3) from white ginseng extract using response surface methodology.

Numai utilizatorii înregistrați pot traduce articole

The optimization of the conversion of ginseng saponin glycosides to 20(S)-ginsenoside Rg(3) by enzymatic transformation was carried out using response surface methodology (RSM) based on a 2(3) factorial central composite design. The production of 20(S)-ginsenoside Rg(3) using several commercial

Antihepatotoxic Actions of Ginsenosides from Panax ginseng Roots1.

Numai utilizatorii înregistrați pot traduce articole

The antihepatotoxic effects of ginsenosides, saponins from PANAX GINSENG, and their aglycones were investigated utilizing carbon tetrachloride (CCl (4))- and galactosamine (GalN)-induced cytotoxicity in primary cultured rat hepatocytes. Prominent protective actions were found with 20(

Antihepatocarcinoma activity of lactic acid bacteria fermented Panax notoginseng.

Numai utilizatorii înregistrați pot traduce articole

Panax notoginseng was used as the medium for lactic acid bacteria fermentation to manufacture product with antihepatocarcinoma activity. The fermentation broth prepared in a 250 mL Erlenmeyer flask was found to possess antiproliferation activity against hepatoma Hep3B cells. At the dosage of 500

Effect of sun ginseng methanol extract on lipopolysaccharide-induced liver injury in rats.

Numai utilizatorii înregistrați pot traduce articole

Sun ginseng (SG) is heat-processed Panax ginseng C.A. Meyer steamed at 120 degrees C, which has ginsenoside-Rg(3), -Rk(1), and -Rg(5) as its main ginsenoside components. The effect of SG on lipopolysaccharide (LPS)-induced liver injury in rats was investigated in this study. Intravenous injection of

The chemical constituents of the Chinese red ginseng were systematically investigated by using various column chromatographic methods including D-101 macroporous adsorptive resins and open silica gel column chromatographies as well as high-performance liquid chromatography.Their chemical structures

Microwave degradation of floatation-enriched ginsenoside extract from Panax quinquefolium L. leaf.

Numai utilizatorii înregistrați pot traduce articole

Even though the degradation of ginsenosides has been thoroughly studied in animals and in vitro using acids, enzymes, and intestinal bacteria, a new degradation method is established for obtaining the ginsenosides Rg(3), Rh(2) and their aglycon 20(S)-protopanaxadiol. This method is based on the

Experimental and epidemiological evidence on non-organ specific cancer preventive effect of Korean ginseng and identification of active compounds.

Numai utilizatorii înregistrați pot traduce articole

Panax ginseng C.A. Meyer has been the most highly recognized medicinal herb in the Orient. The prolonged administration of red ginseng extract significantly inhibits the incidence of hepatoma and also proliferation of pulmonary tumors induced by aflatoxin B(1) and urethane. Statistically significant

In vitro anti-cancer activity and structure-activity relationships of natural products isolated from fruits of Panax ginseng.

Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE Panax ginseng and its extracts have long been used for medical purposes; there is increasing interest in developing ginseng products as cancer preventive or therapeutic agents. The present study was designed to determine biological structure-activity relationships (SAR) for saponins

Novel dammarane-type sapogenins from Panax ginseng berry and their biological activities.

Numai utilizatorii înregistrați pot traduce articole

Three new dammarane-type sapogenins (1, 3, and 5) together with two known ones (2 and 4) were isolated from the total hydrolyzed saponins extracted from Panax ginseng berry. Their structures were elucidated using a combination of 1D and 2D (1)H and (13)C NMR spectra and mass spectroscopy as

Promotion of hair growth by ginseng radix on cultured mouse vibrissal hair follicles.

Numai utilizatorii înregistrați pot traduce articole

A 70% methanol extract from red ginseng (steamed and dried roots of Panax ginseng C. A. Meyer, a kind of Ginseng Radix) had superior activity to that of white ginseng (peeled and dried root of P. ginseng, another kind of Ginseng Radix) in a hair growth promoting assay using mouse vibrissal follicles

Effects of ginseng rhizome and ginsenoside Ro on testosterone 5α-reductase and hair re-growth in testosterone-treated mice.

Numai utilizatorii înregistrați pot traduce articole

This research program on the novel functions of Panax ginseng C. A. Meyer focused on the effects of ginseng rhizome on hair re-growth in androgenetic alopecia. Extracts of red ginseng rhizome showed greater dose-dependent inhibitory effects against testosterone 5α-reductase (5αR) when compared with

Holistic quality evaluation of commercial white and red ginseng using a UPLC-QTOF-MS/MS-based metabolomics approach.

Numai utilizatorii înregistrați pot traduce articole

In traditional Chinese medicine practice, white ginseng (WG) and red ginseng (RG) have traditionally been used for different purposes. In the present study, an ultra-performance liquid chromatography/quadrupole time-of-flight mass spectrometry (UPLC-QTOF-MS/MS)-based metabolomics approach was

Immunopotentiation and antitumor effects of a ginsenoside Rg₃-fortified red ginseng preparation in mice bearing H460 lung cancer cells.

Numai utilizatorii înregistrați pot traduce articole

Antitumor effects of a ginsenoside Rg(3)-fortified red ginseng preparation (Rg(3)-RGP) were investigated in human non-small cell lung carcinoma (H460) cells using in vitro cytotoxicity assay and in vivo nude mouse xenograft model. Immunomodulatory effects of the preparation were also assessed by

Steaming of ginseng at high temperature enhances biological activity.

Numai utilizatorii înregistrați pot traduce articole

The present study was performed to evaluate the effect of steaming ginseng at a temperature over 100 degrees C on its chemical constituents and biological activities. Raw ginseng was steamed at 100, 110, and 120 degrees C for 2 h using an autoclave. The ginseng steamed at 120 degrees C was more
