OBJECTIVE To study the effects of dibenzocyclooctadiene lignans isolated from Schisandra chinensis, such as wuweizisu C, gomisin N, gomisin A, and schisandrin, on the membrane potential in C6 glioma cells. METHODS The membrane potential was estimated by measuring the fluorescence change in

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)

The fruits of Schisandra chinensis (Turcz.) Baill. (Schisandraceae/Magnoliaceae) are a traditional Oriental medicine possessing adaptogenic and hepatoprotective activities. The lignan content in seeds and fruits of the species cultured in various European locations has been investigated. The lignans

Using exhaustive chromatographic separation we have isolated (-)-tigloyl-deangeloyl-gomisin F as a novel dibenzocyclooctadiene lignan from schisandra chinensis. With the help of HPLC, we further isolated (+)-schisandrin, (+)-deoxyschisandrin, (+)-γ-schisandrin, (-)-gomisin J, (+)-gomisin A,

Capillary electrochromatography (CEC) using polymer-based monolithic stationary phase has been developed as a promising method for the determination of lignans of Schisandra chinensis. The columns were prepared by in situ copolymerisation of acrylamide, N,N'-methylenebisacrylamide, vinylsulfonic

The volatile oils were isolated from dried Schisandra chinensis Baill. seeds by Soxhlet extraction (SE), microwave-assisted extraction (MAE), and simultaneous distillation extraction (SDE), and fractions were identified by gas chromatography-mass spectrometry (GC-MS) and high-performance liquid

OBJECTIVE To separate and identify the chemical constituents from the stem of Schisandra chinensis. METHODS Various chromatographic techniques were used to separate and purify the chemical constituents from 95% ethanol extraction of the stem of Schisandra chinensis. Their structures were elucidated

A phytochemical study on the fruits of Schisandra chinensis led to the isolation and characterization of nineteen compounds. The structures of the isolates were determined to be schizandrin, deoxyschizandrin, angeloylgomisin H, gomisin A, gomisin J, (-)-gomisin L1, (-)-gomisin L2, wuweizisu C,

A methanolic extract of dried Schisandra fruit (Schisandra chinensis Baill.; Schisandraceae) significantly attenuated the neurotoxicity induced by L-glutamate in primary cultures of rat cortical cells. Five dibenzocyclooctadiene lignans (deoxyschisandrin, gomisin N, gomisin A, schisandrin, and

Glucose uptake assay-guided fractionations of the methanol extract of Schisandra chinensis led to the isolation of the dibenzocyclooctadiene lignans: gomisin J (1), gomisin N (2), wuweizisu B (3), wuweizisu C (4), gomisin C (5), gomisin D (6), (+)-schisandrin A (7), schisandrin C (8), schisandrol A

Gomisin A, isolated from the fruits of Schisandra chinensis, is one of the dibenzocyclooctadiene lignans. Application of 12-O-tetradecanoylphorbol-13-acetate (TPA, 1 microgram/ear), a tumor-promoting agent, to the ears of mice induces inflammation. Among seven dibenzocyclooctadiene lignans assayed,

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

The drug Wuweizi (dried fruits of Schisandra chinensis or S. sphenantherd) is one of important medicinal means used in the Oriental medicine. The lignans of dibenzo[a,c]cyklooctadiene type are major constituents, a volatile oil with mono- and ses-quiterpens, an oil, organic acids and small amounts
