In present study, the performance and separation characteristics of 21 macroporous resins for the enrichment and purification of deoxyschizandrin and γ-schizandrin, the two major lignans from Schisandra chinensis extracts, were evaluated. According to our results, HPD5000, which adsorbs by the
Shoot-differentiating and undifferentiating callus cultures of Schisandra chinensis were cultured, respectively, on six and two variants of the Murashige and Skoog (MS) medium, differing in the concentration of cytokinin, 6-benzyladenine (BA) and auxin, α-naphthaleneacetic acid (NAA). In methanolic
In the present study, we examined the effects of deoxyschisandrin (DS) from Schisandra chinensis on the amyloid-beta₁₋₄₂ (Aβ₁₋₄₂)-induced memory impairment in mice and investigated the possible antioxidative mechanism. Mice were given an intracerebroventricular (i. c. v.) injection with the
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
Three dibenzocyclooctadiene lignans: deoxyschizandrin (1), gomisin A (2) and schizandrin (3) were isolated from biomass extracts of Schisandra chinensis (Turcz.) Baill. shoot-differentiating callus cultures. The mentioned lignans were not isolated earlier from in vitro cultures of this plant
In order to choose an appropriate extraction method, samples of Schisandra chinensis (Turcz.) Baill were extracted by different methods and it was found that microwave-assisted extraction gave the best results. The contents of schisandrin, schisantherin, deoxyschizandrin, and r-schizandrin of 10
The aim of the study is to establish a new method of quality evaluation and validate its feasibilities by the simultaneous quantitative assay of four lignanoids in Schisandra chinensis. A new quality evaluation method, quantitative analysis of multi-components by single marker (QAMS), was
OBJECTIVE
To determine lignan content in the vine stem of Schisandra chinensis during 12 months and provide the scientific basis for the development and utilization of the resources.
METHODS
Analysis was carried out on an Eclipse XDB C18 column eluted with a mixture of methanol-acetonitrile-water
The systems of mobile phase for the determination of gamma-schisandrin in Schisandra chinensis and its preparations were developed by high performance liquid chromatography (HPLC). The separation was performed on a Shim-pack VP-ODS column (250 mm x 4.6 mm, 5 microm) at 30 degrees C, the detection
A simple and rapid method for determination of six lignans found in plant cell cultures of Schisandra chinensis was developed and validated. The lignans were extracted from plant samples with methanol and the extracts were effectively cleaned by solid-phase extraction using Strata C18-E (Phenomenex)
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
OBJECTIVE
To establish a fingerprint of seeds of Schisandra chinensis (SSC) and develop a method of quantitative analysis of multi-components by single marker (QAMS) for simultaneous determining six lignanoids in SSC.
METHODS
Eleven batches of SSC were determined by HPLC and a common mode of
OBJECTIVE
To establish a quick method for evaluation of the antioxidant activities based on the correlation analysis of lignans content and antioxidant activities of Schisandra chinensis fruits.
METHODS
The content of five lignans components in 37 batches of S. chinensis fruits from different
A simple, economical and effective non-aqueous capillary electrophoresis separation and detection method was developed for the quantification of deoxyschizandrin and gamma-schizandrin in Schisandra chinensis Baill. and its medicinal preparations for the first time. After optimization of separation
Slice-scan method (SS) scans the two-way chromatographic data at each retention time point, and hence obtains the corresponding spectral "slice"s. Then, the spectral slices are transformed into new spectral profiles by spectral transformation, based on which qualitative and quantitative analysis of
