  • Total saponin and oil fraction of Polygala tenuifolia were tested for their anticholesterolemic properties by a "Three day fasting method" on rabbits. It has been reported that saponin have the anticholesterolemic activity, however this activity is not general property of all kinds of saponin. As shown in Table, Polygala saponin has not significant anticholesterolemic activity on rabbits. On administering oil fraction of Radix Polygala, serum cholesterol level in rabbits increased to 224.7% while the control group 43.2%.oup 43.2%.

  • Effect of single administration of Polygala tenuipolia was examined on short-term memory in step through test and the intensity of the immunoreactive c-Fos protein induced by oral administration of ethanol. The acquisition of memory was significantly reduced by ethanol, and ethanol amnesia was remarkably reversed following oral administration of Polygala tenuifolia. c-Fos protein in normal rat brain was highly expressed in order of thalamus, pariental cortex, hippocampus, hypothalamus, amygdaloid and cingulate cortex. The expression of Fos protein was remarkably suppressed by single administration of ethanol. The inhibitory effect of ethanol on expression of Fos protein was reversed by single administration of Polygara tenuipolia, especially tissues of limbic areas such as amygdala, parietal cortex and CA3 of hippocampus. These results suggested that the amelioration process of Polygala tenuipolia on ethanol amnesia seems to be involve the expression of c-Fos protein in partly.

  • Background: Nitric oxide (NO) is a reactive free radical gas and a messenger molecule. NO has many physiological functions, but excessive NO production induces neurotoxicity. Objective: The present study investigated whether the aqueous extract of Polygala tenuifolia Willdenow possesses a protective effect on NO-induced apoptosis in human neuroblastoma cell line SK-N-MC. Method: For this study, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, 4,6-diamidino-2-phenylindole (DAPI) staining, terminal deoxynucleotidyl transferase (TdT)-mediated dUTP nick end labeling (TUNEL) assay, DNA fragmentation assay, reverse transcription-polymerase chain reaction (RT-PCR), Western blot, and caspase-3 enzyme assay were performed. Result: Sodium nitroprusside (SNP) exposure significantly decreased the viability of cells. The cells treated with SNP exhibited several apoptotic features such as increasing of Bax expression, caspase-3 enzyme activity and inhibiting of Bcl-2 expression. On the other hand, the viability of cells pre-treated with the aqueous extract of Polygala tenuifolia Willdenow was increased dose-dependently. The cells pre-treated for 1 h with the aqueous extract of Polygala tenuifolia Willdenow followed by treatment with SNP showed a decreased occurrence of apoptotic features like decreasing Bax expressions, caspase-3 enzyme activity and increasing Bcl-2 expressions. The aqueous extract of Polygala tenuifolia Willdenow reduced apoptotic cell death in neuroblastoma cell line SK-N-MC through the inhibition of Bax-dependent caspase-3 activation and the increasing of Bcl-2 expression. Conclusion: Based on the present results, it is possible that Polygala tenuifolia Willdenow has therapeutic value for the treatment of a variety of NO-induced brain diseases.

  • $Three\;compounds-ethyl-{\beta}-D-glucopyranoside$, 1,2,3,7-tetramethoxyxanthone, 1,7-dimethoxyxanthone-were isolated from roots of Polygala tenuifolia. The structures of these compounds were establised on the basis of spectral evidence including 2D NMR and HMBC studies. $Ethyl-{\beta}-D-glucopyranoside$ was isolated for the first time from Polygala genus and HMBC data of these compounds were first reported.

  • Three medicinal species of the genus Polygala were examined by comparative morphology, anatomy and TLC analysis. They were classified into three species, and distinctly divided into two groups in this study. Group I is composed of P. japonica, P. sibirica and Group II P. tenuifolia. Considered on the relationships between two groups by the differences of leaf shape, adnated part of petal, flower colour, fruit shape etc., Group II may have been independently evolved from the common ancestor by having one raw of palisadelike chlorenchyma under the stem epidermis through the different pathway. It is also suggested that the taxa of Group II appear to be more advanced than those of Group I.

  • From the n-hexane layer of the MeOH extract of the roots of Polygala tenuifolia, three compounds (2-hydroxy-4,6-dimethoxy benzophenone, 3,4,5-trimethoxycinnamic acid ethyl ester and 1,2,3,6,7- pentamethoxyxanthone) were isolated. 2-Hydroxy-4,6-dimethoxybenzophenone and 3,4,5-trimethoxycinnamic acid ethyl ester were first isolated from Polygala genus. Their structures were elucidated employing 2D-NMR, IR, UV, and MS techniques.

  • Objectives: In this study, it was carried out to evaluate the acute oral toxicity of Root of Polygala teunifolia Willd. in Sprague-Dawley (SD) rats. Methods: Male and female rats were administered orally with Root of Polygala teunifolia Willd. water extract of 1,000 mg/kg (low dosage group), 2,000 mg/kg (middle dosage group) and 4,000 mg/kg (high dosage group). We daily observed number of deaths, clinical signs and gross findings for 7 days. After 7 days, we measured body and organs weight. Also we analyzed hematological changes. Results: No dead SD rats and no clinical signs were found during the experiment period. Also other specific changes were not found between control and treated groups in hematology and serum biochemistry. But we found out histopathological changes in liver fat tissues of female. In addition, there were no significant changes of gross body and individual organs weight. Conclusions: These results suggest that water soluble extract of Root of Polygala teunifolia Willd. has not acute oral toxicity and oral $LD_{50}$ value was over 4,000 mg/kg in SD rats.
