gomisin n/schisandra chinensis

The fruits of Schisandra chinensis have been used for the treatment of insomnia in oriental countries for more than thousands of years. However, the pharmacological properties and the mechanism of sedative and hypnotic effects have not yet been studied. Gomisin N is one of the major bioactive

Overproduction and accumulation of melanin in the skin can lead to pigmentation disorders, such as freckles and melasma. Many researchers are studying the regulation of melanogenesis in the skin with the aim of developing whitening cosmetics. In this study, bioactivity-guided separation of the

Gomishi is the dried fruit of Schisandra chinensis Baillon (Fructus Schisandrae chinensis, FSC) and has been used in Japanese Kampo medicine to treat inflammatory and liver diseases. However, it is unclear which constituent of FSC is primarily responsible for its pharmacological effects. FSC was

Obesity results from an imbalance between energy intake and energy expenditure, in which excess fat is stored as triglycerides (TGs) in white adipocytes. Recent studies have explored the anti-obesity effects of certain edible phytochemicals, which suppress TG accumulation and stimulate a brown

Lignans isolated from Schisandria chinensis have been prescribed as anti-cancer and anti-hepatitis treatments in Chinese medicine. To investigate the applications of lignans isolated from Schisandria chinensis in hepatic carcinoma therapy, their apoptotic ability was screened using a cell

Schiandra chinensis is a well-known Chinese traditional medicine for the treatment of hepatic disease. In this study, we investigated whether the nine major compounds of Schiandra chinensis could be applied to suppress lipopolysaccharide (LPS)-induced inflammatory responses in murine macrophages

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

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 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 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 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

What's known on the subject? And what does the study add? Schisandra chinensis extract (SCE) has been known to have relaxative effects on penile smooth muscle. A recent study showed that SCE could enhance slidenafil citrate-induced relaxation of penile corpus cavernosum. The current study

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

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
