BACKGROUND Polygala paniculata Linnaeus (Polygalaceae) has shown neuroprotective effects, but there is no report about its antidepressant potential. OBJECTIVE The antidepressant-like effect of the hydroalcoholic extract from P. paniculata and some of the possible mechanisms involved in this effect

OBJECTIVE To investigate the antidepressant components of Polygala tenuifolia. METHODS The chromatographic method was used to isolate and purify the chemical constituents, their structures were identified by spectral analysis, MTT method was applied to investigate their cytotoxic

YZ-50 is an active fraction obtained from the root of Polygala tenuifolia Willd. (Polygalaceae) extract and it has been reported previously to exert beneficial effects on mental health in depressed sufferers, however, its mechanism of action remains unresolved. This study utilized the chronic mild

Yuanzhi, the dried root of Polygala tenuifolia Willd., is a well-known traditional Chinese medicine used for its sedative, antipsychotic, cognitive improving, neuroprotective, and antidepressant effects. The present study was designed to screen and identify the antidepressant-like effect of six

Shen Yuan Gan (SYG) is a Chinese herbal prescription composed of total saponins of Panax ginseng and total oligosaccharide esters of Polygala tenuifolia (2:1). Our previous studies have demonstrated that SYG has antidepressant-like effects in various mouse models of behavioral depression. The

Radix Polygalae (the root of Polygala tenuifolia) is a herb widely used in traditional Asian medicine that is thought to exert a variety of neuropsychiatric effects. Radix Polygalae extract can protect against N-methyl D-aspartate (NMDA) neurotoxicity and induce brain-derived neurotrophic factor

OBJECTIVE The present study was designed to observe the effects of 3,6'-disinapoyl sucrose (DISS), an active oligosaccharide ester component obtained from the roots of Polygala tenuifolia Willd., on behavioral and biochemical aspects of depression induced by chronic mild stress (CMS) in rats. It is

Radix Polygalae ("Yuan Zhi", the roots of Polygala tenuifolia Willd., YZ) is an important herb used in traditional Chinese medicine to mediate depression. The present study was designed to verify the antidepressant effects of the standardized YZ ethanol extract (YZE) and its four fractions YZ-30,

Depressive disorder is a kind of affective disturbance disease. Emerging evidence has suggested that inflammation may contribute to the pathologic process of depressive disorder. Senegenin (SEN), a major bioactive constituent in Polygala tenuifolia Willd, has much bioactivity including

Recent studies suggest that the behavioral effects of chronic antidepressant treatment are mediated by stimulation of hippocampal neuronal plasticity and neurogenesis. The present study was designed to examine the effects of 3,6'-disinapoyl sucrose (DISS), a bioactive component of Polygala

[(125)I]RTI-55-membrane binding assay-guided fractionation and separation of a water-soluble extract of the roots of Polygala tenuifolia gave five new oligosaccharide derivatives, polygalatenosides A-E (1-5). The structures of these new oligosaccharides were established on the basis of spectroscopic

The relationship between depression and monoaminergic systems has been hypothesized for many years. In this study, we have investigated the possible antidepressant-like effect of scopoletin, a coumarin from Polygala sabulosa in the tail suspension test and forced swimming test. Moreover, the ability

OBJECTIVE To observe the effect of Polygala tenuifolia Willd YZ-50 on the mRNA expression of brain-derived neurotrophic factor (BNDF) and its receptor TrkB in rats with chronic stress depression.es. METHODS Normal male Wistar rats were divided in to control group, model group, desipramine (20 mg/kg)

3,6'-Disinapoyl sucrose (DISS) is the active oligosaccharide ester component from roots of Polygala tenuifolia, and its antidepressant effects was found in the forced swimming test (FST) and tail suspension test (TST). We aimed to study the antidepressant effects of DISS in the chronic unpredictable

Three phenylpropenoyl sucroses--sibiricose A5, A6 and 3',6-disinapoyl sucrose--were isolated from the 30% EtOH extract of Polygala tenuifolia, which displayed antidepressant-like action. HPLC analysis indicated that the three phenylpropenoyl sucroses could be absorbed into serum. From the serum
