BACKGROUND Schisandrol A, a lignan with anticancer effects, is one of the representative components that identifies Schisandra chinensis. OBJECTIVE A method for purifying schisandrol A from the stems of S. chinensis was established using an octadecylsilyl (ODS) column combined with preparative

Recent studies have shown that dibenzocyclooctadiene lignans may reverse P-glycoprotein-mediated multidrug resistance (Pgp-MDR) in cancer cells; however, the mechanism of action remains unknown. Through screening of herbs, we found that schisandrol A (SCH) isolated from Fructus Schisandrae (the

OBJECTIVE To study the chemical constituents from the supercritical CO2 extraction of Schisandra chinensis. METHODS The compounds were separated and purified by conventional column chromatography and their structures were identified by spectroscopic methods. RESULTS Nine compounds were isolated from

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 aim of the study is to investigate rat intestinal absorption behavior of three main active components, schisandrol A, schisandrin A and schisandrin B in Schisandra chinensis Baill extracts in intestine of rats. With phenol red as the indicator, in situ single pass intestinal perfusion (SPIP)

OBJECTIVE To investigate the quality of Schisandra chinensis, and thus provide the useful reference data for its quality standard establishment and standardized cultivation. METHODS Base on the Chinese Pharmacopoeia and literature relating to S. chinensis, the appearance, water-soluble extractive,

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.

OBJECTIVE To determine the contents of lignans, crude polysaccharides (CP) and total phenolic compounds (TPC) of Schisandra chinensis from various habitats in Liaoning province and evaluate their quality and free radical scavenging (FRS) activity. METHODS Contents of schisandrol, deoxyschizandrin

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
