Chronic airway inflammation is a hallmark of asthma, which is an immune-based disease. We evaluated the ability of saucerneol D, a tetrahydrofuran-type sesquilignan isolated from Saururus chinensis, to regulate airway inflammation in an ovalbumin (OVA)-induced airway inflammation model. Furthermore,

BACKGROUND Antiacetylcholinesterase (AChE) drugs have been a main therapeutic treatment for Alzheimer's disease because increased AChE levels play a key role in reducing neurotransmission. OBJECTIVE Extracts from 35 Korean plants were selected and screened for antioxidant and anti-cholinesterase

A new diarylbutane lignan, saururin A (1), and a known 8-O-4'-type neolignan, machilin D (2), were isolated from a total methanol extract of the underground parts of Saururus chinensis. The structures of 1 and 2 were elucidated by spectroscopic data analysis. Compounds 1, 2, and virolin (3) (the

A new diarylbutane lignan, 2'-hydroxy dihydroguaiaretic acid (4), and a known 8-O-4'-type neolignan, machilin D (5), were isolated from the ethyl acetate extracts of the underground parts of Saururus chinensis. Compounds 4 and 5 exhibited low-density lipoprotein (LDL)-antioxidant activity in the

BACKGROUND A Saururus chinensis Baill (SC) has been used by Native Americans, early colonists and practitioners of Korean traditional medicine for treating several diseases including cancer, rheumatoid arthritis and edema. The objective of this study was to evaluate the effects of SC extract in

Evaluation of antioxidant and anticancer activities were screened by various Saururus chinensis root extracts. Four solvents (ethyl acetate, methanol, ethanol, and water) extracts were investigated for their total flavonoids, phenol contents and their antioxidant activity of DPPH

Natural products are known to be sources of bioactive components exerting antioxidative and anti-inflammatory activities. We evaluated the suppressive effects of the methanol extract (0-45 microg/mL) of the aerial parts of Saururus chinensis (Lour.) Baill (Saururaceae) on lipopolysaccharide

This study investigated the preventive effect of Saururus chinensis Baill against renal damage induced by a high-fructose diet in rats. The rats (n = 30) were fed either a cornstarch-based (65%), high-fructose (65%), or high-fructose (64.5%) diet with 0.5% S. chinensis Baill extract for 10 weeks.

This study was performed to investigate the effect of ethanol extract from Saururus chinensis (Lour.) Baill on liver function, plasma lipid composition and antioxidant system with high-fat diet for 4 weeks. Rats were divided into the following five groups; untreated control group (normal), treated

A new triene, 12,13-dehydrogeranylgeraniol (1), was isolated from the aquatic plant Saururus cernuus and its structure determined spectroscopically. Compound 1 inhibits PMA-induced peroxide-catalyzed oxidation of 2',7'-dichlorodihydrofluorescein dye (DCFH) by reactive oxygen species (ROS) within

BACKGROUND Saururus chinensis is a medicinal plant used to treat jaundice, pneumonia, edema, fever, and several inflammatory diseases. Saucerneol D (SD), a lignan constituent of this plant, has antioxidant, anti-asthmatic, and anti-inflammatory activities. SD has been previously reported to inhibit

meso-Dihydroguaiaretic acid (MDGA), which is a dibenzylbutane lignin isolated from the ethyl acetate fraction of Saururus chinensis, has various biological activities, including anti-oxidative, anti-inflammatory, anti-bacterial, and neuroprotective effects. However, no report has examined the

It was reported previously that ESP-102, a combined extract of Angelica gigas, Saururus chinensis and Schizandra chinensis, significantly improved scopolamine-induced memory impairment in mice and protected primary cultured rat cortical cells against glutamate-induced toxicity. To corroborate this

An activity-guided fractionation procedure was used to identify the antioxidative components of the aerial parts of Saururus chinensis. The antioxidant activity was investigated with the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical- and superoxide anion-scavenging assays. Three active compounds
