Composition and Biochemical Properties of Ale Beer Enriched With Lignans From Schisandra chinensis Baillon (Omija) Fruits

Alleen geregistreerde gebruikers kunnen artikelen vertalen

To develop a beverage with high antioxidant capacity and desirable sensory characteristics, Schisandra chinensis (omija) fruits were added to ale type beer at different time points of the brewing process. The phenolic compounds contents in beer were found to be dependent at the moment of the

Isolation of three dibenzocyclooctadiene lignans from in vitro cultures of Schisandra chinensis (Turcz.) Baill.--the first report.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

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

Production of lignans in calluses of Schisandra chinensis.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

Calluses were induced from leaves of Schisandra chinensis Baillon (Schisandraceae). Murashige-Skoog (MS) and Woody Plant (WP) media were used for the induction, in full and half strength (1/2 MS or 1/2 WP) salt formulations. Test media were solidified with 0.25% gelrite and supplemented with 2%

Validated method for bioactive lignans in Schisandra chinensis in vitro cultures using a solid phase extraction and a monolithic column application.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

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)

Wuweizisu C from Schisandra chinensis decreases membrane potential in C6 glioma cells.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

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

Micelle-mediated extraction of dibenzocyclooctadiene lignans from Schisandra chinensis with analysis by high-performance liquid chromatography.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

Micelle-mediated extraction offers a convenient alternative to conventional extraction systems. A new method based on micelle-mediated extraction was developed for the separation and determination of dibenzocyclooctadiene lignans from Schisandra chinensis by high-performance liquid chromatography

Transport of Schisandra chinensis extract and its biologically-active constituents across Caco-2 cell monolayers - an in-vitro model of intestinal transport.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

We have determined the intestinal transport of Schisandra chinensis extract and its lignans (gomisin A, gomisin N and schisandrin C) in the Caco-2 cell monolayer model. The transport across monolayers was examined for 2 h in absorptive and secretory directions. Quantitation of lignans was performed
