schisantherin a/schisandra chinensis

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 study different processing method and mature stage on the quantity of the Schisandra chinensis in the Xinbin region of Liaoning. METHODS The schisantherin A and 5-hydroxymethylufrurfal (5-HMF) content in S. chinensis was determined by using the HPLC method. The organic acids content was

The present work shows the application of the temperature-correlated mobility theory for the optimization of the separation and peak alignment of the main lignans from water extracts of traditional Chinese medicine Schisandra Chinensis Fructus as well as its prescription Yuye Decoction (Jade Fluid

A simple, rapid and sensitive method was developed for the simultaneous quantification of four active schisandra lignans (schisandrin, schisantherin A, deoxyshisandrin and gamma-schisandrin) from a traditional Chinese medicine Schisandra chinensis(Wuweizi) in rat plasma using a high-performance

Aggregated beta-amyloid (Aβ) and elevated plasma levels of homocysteine have been implicated as critical factors in the pathogenesis of Alzheimer's disease. The neuroprotective effects and possible mechanism of four structurally similar dibenzocyclooctadiene lignans (namely schisandrin,

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

A method for two-steps extraction of essential oil, polysaccharides and lignans from Schisandra chinensis Baill had been established. Firstly, S. chinensis was extracted by hydro-distillation, the extracted solution was separated from the water-insoluble residue and precipitated by adding dehydrated

Schisandra chinensis (Turcz.) Baill., a traditional Chinese medicine, has been used for treating insomnia for centuries. This paper was designed to study on the plasma pharmacokinetic for its absorption process, and to compare the pharmacokinetics of its active ingredients in normal and insomnic

Schisandra chinensis (Turcz.) Baill., a traditional Chinese medicine, has been clinically used for the treatment of insomnia for centuries. The insomnia mechanism and the possible active ingredients of S. chinensis remain largely unknown. The objective of this study was to develop a method to detect

Schisandra chinensis is one of the most famous herbal medicines in China, Korea and Japan. It has been widely used as a tonic, sedative, anti-aging and astringent agent. Lignans are one of its main bioactive components. The classical methods for extracting lignans, however, were tedious and

Homogeneous ionic liquid microextraction (HILME) was developed for the extraction of schizandrin, schisantherin A and deoxyschizandrin from Schisandra chinensis and Schisandra sphenanthera. 1-Butyl-3-methylimidazolium tetrafluoroborate ([C(4)MIM][BF(4)]) aqueous solution was used as extraction

One new sesquiterpene (α-iso-cubebenol acetate, 8), together with 9 known compounds (1-7, 9, 10) were isolated from the stems of Schisandra chinensis (Turcz.) Baill. by repeated silica gel column chromatography. Based on the results of MS, NMR spectra and comparing with literature data, the six

It is highly valuable to study the pharmacokinetics of herbal components under the pathological condition of liver dysfunction for safe and rational use of herbal medicines. In this study, the pharmacokinetic profiles of four effective lignans from Schisandra chinensis (SC), schisandrin,

Deoxyschisandrin (VIII) and five new lignans, named schisantherin A, B, C, D, and E, were isolated from the active fraction of the fruits of Schisandra sphenanthera Rehd. et Wils. Their configurations and conformations were established by exhaustive spectral analysis as well as chemical degradations

Currently the pharmacokinetic (PK) research of herbal medicines is still limited and facing critical technical challenges on quantitative analysis of multi-components from biological matrices which often accompanied by lacking of authentic standards and low concentration. This present work
