  • A new approach for similarity analysis of chemical profiles of Scrophularia buergeriana was developed. The roots of S. buergeriana collected in Andong, Korea were analyzed using HPLC-DAD and the peak areas of the chromatograms were used to construct the chemical profiles of S. buergeriana. The analytical conditions were validated for specificity, precision and repeatability. The standard chemical profiles were established from the chromatograms of nine standard analytical extracts from three batches. The correlation coefficients of peak areas of characteristic compounds between the chromatograms of the standard and test samples were calculated for quantitative expression of the chemical profiles. The results showed that the HPLC chemical profiles of the samples of same geographic origin were relatively consistent. This new approach could be applied to the quality assessment of herbal medicines with complex chemical compositions.

  • Background: This study was conducted to investigate the effects of germination temperature, storage container and storage temperature on Scrophularia buergeriana and Scrophularia takesimensis seeds. Methods and Results: Seed lengths of both species were 0.8 mm, while seed width differed, with S. buergeriana measuring 0.5 mm and S. takesimensis measuring 0.4 mm. The seeds of S. buergeriana were packaged in paper containers under room temperature ($15^{\circ}C$), cold temperature ($4^{\circ}C$), and freeze temperature ($-20^{\circ}C$). These seeds exhibited around 80% germination rate at temperatures between $15^{\circ}C$ and $30^{\circ}C$. The germiantion rate of S. takesimensis, on the other hand, differed significantly at different germination temperatures. Seeds of S. takesimensis which were packaged in vinyl and paper containers and stored under room and cold temperatures, exhibited around 80% germination rate at $15^{\circ}C$. However, the germination rate of freeze-stored seeds were decreased to lower than 20% at germination temperatures of $15^{\circ}C$, $25^{\circ}C$ and $30^{\circ}C$ germiantion conditions. The rate of germination showed a low positive to a significantly negativie correlation with the other factor that were determined to evaluate the germination performance. Conclusions: This study elucidates the most suitable germination and storage conditions to increase the germination rate for the two species of Scrophularia buergeriana and Scrophularia takesimensis needs to be stored in paper containers under cold temperature and requires a temperature of $20^{\circ}C$ for germination. On the other hand, S. takesimensis in vinyl containers need to be stored at room temperature and those in paper containers at cold temperature, and a temperature of $15^{\circ}C$ is required for germination.

  • 현삼의 기내배양에서 TDZ처리가 비교적 재분화에 효율적이었고 형질전환 식물체를 선발하기 위하여 선발표지 유전자로 사용되는 NPTII gene이 항생제 kanamycin에 대한 저항성은 50 mg/L가 적당하였다. 선발배지에서 자란 현삼 식물체에서 DNA를 추출하여 PCR 분석을 통하여 특정 유전자 Gh-5 gene을 검정한 결과 형질전환되지 않은 식물체에서는 볼수가 없는 988 bp의 band가 형질전환된 식물체에서는 관찰되어 GST 유전자가 현삼의 염색체 안으로 삽입되었음을 확인하였다. 형질전환 효율 증진을 위하여 선발과정에서 암상태를 30일까지 유지할 경우 높은 형질전환 효율을 나타내었으나 그 이상의 처리는 오히려 형질전환 효율이 감소하는 결과를 나타내었다 (Table 5). 형질전환 식물체에서 GST의 활성이 형질전환 되지 않은 식물체의 2배로 나타났고 유도체의 적정 처리 농도는 50$\mu$M이며 유도체 처리 시간에 따라서는 12시간까지는 점차적으로 높아지는 경향이었으나 그 이상의 시간에서는 활성이 저하됨이 확인되었다. Fungus 피검균인 Asperigillus awamori에서 6, 12시간 처리 시 비교적 높은 활성을 보여주었으며 그 이상의 시간처리에서는 명확한 균사 억제를 나타내지 못하였으며, 특히 12시간에서 상대적으로 높은 활성을 나타내었다. Cladosporium herbarum에서 형질전환된 식물체의 활성이 훨씬 높게 나타났으며 6시간 처리에서 다른 처리에 비하여 높은 활성을 나타내었다. 피검균인 Saccharomyces cerevisiae에서는 형질전환 식물체에서 높은 활성을 보여주었으며 6, 12시간 처리에서 비슷하게 높은 활성을 보여 주었다. 박테리아 피검균 Bacillus subtillis에서는 50$\mu$M 이하의 유도체 처리에서 비교적 높은 활성을 나타내었다.

  • Scrophularia buergeriana Miquel (Scrophulariaceae) has been used as an anti-inflammatory drug in the folk medicine recipe and been proved its anti-inflammatory effect in the oriental medicine. Since nitric oxide (NO) and superoxide anion (O/sub 2//sup -/) are ones of the major inflammatory parameters, we studied the effect of aqueous extracts of Scrophularia buergeriana (SB) on NO and O/sub 2//sup -/ production in lipopolysaccharide (LPS)-stimulated mouse peritoneal macrophages. NO, O/sub 2//sup -/production and inducible NO synthase (iNOS) level were significantly reduced in LPS-activated macrophages by SB compared to those without. Electrophoretic mobility shift assay (EMSA) indicated that SB blocked the activation of NF-kB, which was considered to be a potential transcription factor for the iNOS expression. SB also blocked degradation of IkBα. Furthermore, IkB kinase alpha (IKKα), which phosphorylates serine residues of IkB directly, is inhibited by SB. These results suggest that SB could exert its anti-inflammatory actions by suppressing the activation of NF-kB through inhibition of IKK activity.

  • The present study was performed to investigate the putative anxiolytic-like effects of the aqueous extract of the roots of Scrophularia buergeriana (SB-W) using elevated plus-maze (EPM) and hole-board apparatus in mice. SB-W was orally administered at doses of 50, 100, 200 or 400 mg/kg to ICR mice, 1 h before the behavioral evaluation. Control group were administered with an equal volume of saline, and positive control group with buspirone (2 mg/kg, i.p.). The administration of SB-W significantly increased the percentage of time spent in open arms and entries into the open arms of the EPM compared with saline-treated control group (P < 0.05). Futhermore, those anxiolytic-like activities of SB-W were antagonized by flumazenil (a $GABA_A$ antagonist, 10 mg/kg), but not by WAY-100635 (a 5-$HT_{1A}$ antagonist, 0.3 mg/kg). Moreover, there were no changes in the locomotor activity and myorelaxant effects in any group compared with saline-treated control group. In the hole-board test, the administration of SB-W (200 and 400 mg/kg) significantly increased the number of head-dipping compared with saline-treated control group (P < 0.05). Therefore, these findings suggest that Scrophularia buergeriana promotes the anxiolytic-like activity mediated by GABAergic nervous system in mice.
