Liver regeneration is a vital process of recovery after liver damage, which is a promising clinical strategy after partial hepatectomy (PHx). Schisandrol B (SolB), one of the bioactive ingredients from Schisandra sphenanthera, displays significant hepato-protection effects against drug-induced liver
Acetaminophen (APAP) overdose is the most frequent cause of drug-induced acute liver failure. Schisandra sphenanthera is a traditional hepato-protective Chinese medicine and Schisandrol B (SolB) is one of its major active constituents. In this study, the protective effect of SolB against
Aberrant transforming growth factor β1 (TGFβ1) signaling plays a pathogenic role in the development of vascular fibrosis. We have reported that Schisandra chinensis fruit extract (SCE), which has been used as a traditional oriental medicine, suppresses TGFβ1-mediated phenotypes in vascular smooth
OBJECTIVE
The nuclear factor erythroid 2-related factor 2 (NRF2) acts through the antioxidant response element (ARE) to regulate the expression of many detoxifying and antioxidant genes responsible for cytoprotective processes. We previously reported that Schisandrol B (SolB) isolated from
Currently, ursodeoxycholic acid and obeticholic acid are the only two FDA-approved drugs for cholestatic liver diseases. Thus, new therapeutic approaches need to be developed. Here we have evaluated the anti-cholestasis effects of Schisandrol B (SolB), a bioactive compound isolated from Schisandra
Contents of schisandrol A and schisandrol B were determined in methanolic extracts of biomass from in vitro cultures of Schisandra chinensis (Turcz.) Baill. (Schisandraceae) using an HPLC method. The biomass was cultured on six variants of Murashige and Skoog (MS) medium containing different
1. Schisandra chinensis, also called wuweizi in Chinese, is the fruit of Schisandra chinensis (Turcz.) Baill., and has been officially utilized as an astringent tonic for more than two thousand years in China. This study aims to evaluate the inhibition of carboxylesterases (CESs) by the major
Seven lignans from Schisandra chinensis were investigated for their inhibitory activity on NFAT transcription. Both gomisin N (IC 50 : 1.33 +/- 0.05 microM) and schisandrol A (IC 50 : 1.34 +/- 0.05 microM) showed higher activity than gomisin E (IC 50 : 4.73 +/- 0.09 microM), schisandrin A (IC 50 :
This study examined the use of ultrasonic-assisted extraction (UAE) coupled with column chromatography (CC) and supercritical antisolvent (SAS) precipitation in purifying five lignans from the dried fruit of Schisandra chinensis. Column fractionation of the ultrasonic extracts and SAS precipitation
Lignans are the bioactive constituents in Schisandra chinensis fruits. For the first time major representatives could directly be determined in plant extracts by using Supercritical Fluid Chromatography. Based on nine commercially available standards the method was developed, finally permitting
An online supercritical fluid extraction with supercritical fluid chromatography system could provide sequential extraction and quantitative analysis of lignans in Schisandra chinensis. Supercritical fluid extraction conditions were optimized at 15 MPa, 50°C, and 4 min with supercritical
The effect of plant growth regulator forchlorfenuron (CPPU) 1 x 10(-6), 0.67 x 10(-6), 0.5 x 10(-6) on fruit morphology and effective components lignans was studied. Those morphologies were the combination of four basic morphological changes. The result showed, diametre were increased and
The fruit of Schisandra chinensis is a well-known herbal medicine and dietary supplement due to a variety of biological activities including antihepatotoxic and antihyperlipidemic activities. However, the simultaneous validation methodology and pharmacokinetic investigation of nine lignans of S.
Bioactivity-guided fractionation of the fruits of Schisandra chinensis, using the proprotein convertase subtilisin-kexin type 9 (PCSK9) mRNA expression screening assay, led to isolation of two previously unknown lignans, 14-tigloylschinlignan D and rel-(7R, 8R, 7'R, 8'R)-manglisin E, along with 28
This study is to investigate the effects of aqueous extract of Schisandra chinensis Baill (WWZ), kadsurin, schisandrin A, schisandrin B and schisandrol B on rat hepatic CYP3A. Rats received a daily gavage of aqueous extract of WWZ for different times. The livers were harvested after gavage and
