Oxymatrine, a quinolizidine natural drug extracted from Sophora japonica, has been reported to have neuroprotective effect and cardioprotective effect. However, the protective effect of oxymatrine on arsenic trioxide (As2O3)-induced liver injury has not been reported. In the present study, we investigated the protective effects of oxymatrine on As2O3-induced liver injury in rats. Male Wistar ra...
A new flavonoid, (2R,3R)-3,7,4'-trihydroxy-3',5'-dimethoxyflavanone, named sophorayunnanol (1), together with eight known polyphenols (2-9), were isolated from the roots of Sophora yunnanensis C.Y.MA (Leguminosae). The structure including absolute stereochemistry of 1 was determined by spectroscopic (high resolution (HR)-MS, 1D- and 2D-NMR, and circular dichroism (CD)) methods. The inhibitory a...
The present study investigated the sedative effects of Sophora flavescens (SF) and its bioactive compound, matrine through performing locomotor activity test and the electroencephalography (EEG) analysis in the rat. The underlying neural mechanism of their beneficial effects was determined by assessing c-Fos immunoreactivity and serotonin (5-HT) in the brain utilizing immunohistochemical method...
Sophora is a woody genus of the Leguminosae in which an unusual order and process of floral organ development is often observed. The SEM results for Sophora tetraptera revealed precocious initiation of the carpel, delayed development of petals, and floral organ development interrupted by an unusual prolonged summer-autumn dormant period which occurred between organ initiation and organ differen...
Our previous study showed that kurarinone was the main hepatotoxic ingredient of Sophora flavescens, accumulating in the liver. This study characterized the mechanism of Sophora flavescens extract (ESF) hepatotoxicity and hepatic accumulation of kurarinone. ESF impaired hepatic function and caused fat accumulation in the liver after oral administration (1.25 and 2.5 g/kg for 14 days in rats). S...
Previously, it was reported that some prenylated flavonoids contained in the dichloromethane fraction of the ethanolic extract of Sophora flavescens, such as kuraridin, sophoraflavanone G, kurarinone, and kushenol F, are tyrosinase inhibitors; however, based on the level of these inhibitors in the extract, its inhibitory effect on tyrosinase activity was higher than expected. This has led us to...
