  • Scutellariae baicalensis GEORGt Acorus gramineus SOLAND and Gastrodia elata BLUME are traditional medicines used in the treatment of incipient stoke. In this study we investigated their effects on various aspects of neuronal differentiation in single or composite forms. Water-extracts of these medicines showed neuroprotective effects on cultured rat cortical neurons in normoxia and hypoxia. To understand the mechanism for neuroprotection we carried out various cell biological assays. They stimulated initial differentiation of neuronal development (transition from stage 1 to 2), and increased the number of spines and the length and number of dendritic processes. These effects were best manifested in the experimental group, which were given a mixture of the three kinds of extracts (p<0.01). To assess improvement of brain functions we carried out Morris water-maze tests for the mice that were fed on these extracts instead of water for 4 weeks. The experimental groups, especially those which were given the mixture of the three kinds of extract, showed significant (p<0.01) enhancement in memory as early as one day after the learning trial. These results indicate that these three kinds of extracts have synergistic effects on neuronal protection and improvement of brain functions.

  • Objectives : Parkinson's disease (PD) is a neurodegenerative disorder threatening the quality of life and highly occurred in over 65 years old. Gastrodia elata Blume (GEB), a traditional medicine used for the treatment of headache and convulsion, has been reported to have neuroprotective effect. This study was designed to investigate the neuroprotective effect of GEB and the proteomic changes in the substantia nigra (SN) of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-treated mice. Methods : Male eleven-week-old C57BL/6 mice were intraperitoneally injected with 30 mg/kg of MPTP at 24-h intervals for 5 days. Two hours after the daily MPTP injection, the mice were orally administered 800 mg/kg of GEB extract, which continued for 7 days beyond the MPTP injections, for a total of 12 consecutive days. Two hours after the final GEB administration, the brain samples were collected, and dopaminergic neuronal death and proteomic changes in the SN were evaluated. Results : GEB prevented the MPTP-induced dopaminergic neuronal death and regulated the expression of 11 proteins including thimet oligopeptidase, T-complex protein 1, glycine tRNA ligase, and pyruvate kinase isozymes M1. Conclusions : GEB prevents MPTP-induced dopaminergic neuronal death by regulating the proteins in the SN.

  • 천마를 다양한 용매(물, 에탄올 및 70%) 및 다양한 농도 (0.725, 1.25, 2.5 및 5 mg/mL)로 추출하고 추출된 물질을 젖산균과 유용미생물(Effective Microorganisms)로 발효시킨 다음, 이들 물질들이 화장품 소재로 활용 가능한가를 확인하였다. 물, 에탄올 및 70% 에탄올로 추출한 물질들을 각각 0.725, 1.25, 2.5 및 5 mg/mL 농도에서 실험한 결과, flavonoid, polyphenol 및 DPPH free radical scavenger 등과 같은 항산화물질은 에탄올 추출물에 가장 많이 함유되어 있었고, DPPH radical 소거능은 유용미생물로 발효시킨 천마를 에탄올로 추출한 경우 1.25 mg/mL에서 $27.08{\pm}0.5%$이었으나 2.5 mg/mL에서는 $27.08{\pm}0.5%$로 증가하였다. 미백 활성을 측정할 수 있는 tyrosinase 활성 저해 실험에서는 EtOH 추출물을 젖산균으로 발효시켰을 때 가장 저해 효과가 우수하였고(0.725 mg/mL에서 $39.1{\pm}0.4%$, 2.5 mg/mL에서 $62.8{\pm}1.5%$), RAW 264.7 Cells을 이용한 세포 생존율 실험 결과 물, EtOH, 70% EtOH 추출물과 이들의 발효 물질 모두 85%이상의 세포 생존율을 나타내 세포의 염증에 대한 안정성을 확인하였다. ROS 생성으로 인한 항산화 실험에서는 양성 대조군으로 RAW 264.7 cells을 lipopolysaccharide로 자극시켜 활성화된 세포에 비발효와 발효에 따른 추출물을 농도별로 처리하였을 때 유효미생물로 발효시켰을 경우가 가장 항산화성이 높은 것으로 확인하였다. 이상과 같은 연구결과 천마 추출 및 발효 물질은 화장품용 항산화제, tyrosinase 활성 저해제 및 항염증제로 사용될 수 있음을 알았다.

  • In order to find active ingradients having an agonistic activity to benzodiazepine receptor from Gastrodia elata Blume (Orchidaceae) which has been used as an anticonvulsant in oriental medicine, one component and some fractions were separated from the butanol extract of the rhizomes of this plant and evaluated for their activities on GABA/benzodiazepine receptor in vitro. As a result, one crude mixture (F4f) obtained from the most active fraction (F4) inhibited significantly the binding of $[^3H]Ro15-1788$, a selective benzodiazepine receptor antagonist, to benzodiazepine receptor of rat cortices. GABA significantly enhanced the inhibition of $[^3H]flunitrazepam$ binding by F4f, and this positive GABA shift supported the strong possibility of the agonistic activity of F4f to benzodiazepine receptor.

  • This study was carried out to analyze the differences in p-hydroxylbenzyl alcohol (HBA) content, antitumor and anti-obesity activities and tyrosinase inhibitory activity between non-fermented G. elata (NFGP) and fermented G. elata powder. The HBA content, which is an index-component of G. elata decreased from 1.58 mg/g before fermentation to 1.07, 0.32, and 0.13 mg/g after the $1^{st}$ fermentation ($1^{st}$ FGP), $2^{nd}$ fermentation ($2^{nd}$ FGP) and $3^{rd}$ fermentation ($3^{rd}$ FGP), respectively. The anti-proliferation effects on the cell lines HT29 and AGS were significantly higher for the fermented G. elata than the NFGP. The antitumor activity was also increased in a fermentation number-dependent manner. During adipocyte differentiation, the ethanol extract of the $3^{rd}$ FGP inhibited lipid accumulation in 3T3-L1 cells significantly better than NFGP and the $1^{st}$ FGP, treated at the concentration of $10{\mu}g/mL$. The tyrosinase inhibitory activity of the $2^{nd}$ FGP at $600{\mu}g/mL$ over was higher than that of kojic acid. At the concentration of $1,000{\mu}g/mL$, the tyrosinase inhibitory activity was increased in a fermentation number-dependent manner. From these results, the fermented G. elata, especially the $3^{rd}$ FGP, is expected to be good candidate for the development of functional food and agents with antitumor, anti-obesity, and tyrosinase inhibitory potential.

  • 천마 재배에서 차광방법 개발과 접종목 재활용의 가능성을 검정하여 저 비용, 고 생산의 재배법을 확립하기 위한 실험을 수행하였다. 비가림을 하지 않은 노지재배에서는 종마의 수량이 성마의 수량 보다 높았다. 차광 방법에 따른 천마의 수량은 $95\%$ 차광망 1겹, 2겹 및 무차광순 이었으며, 접종목 혼용에 따른 천마의 수량은 생목만 사용하였을 경우에 가장 높았고, 다음으로는 생목과 재활용목을 2:1로 및 1:1 혼용처리 처리 순이었다. 접종목 혼용에 따른 수익성 비교에서 $95\%$ 차광막 1겹 처리시 생목과 재생목을 2:1로 혼용한 경우는 생목만 사용한 경우 수익의 $81\%$이었다. 재배법 개선을 통해 수량성을 높일 수 있다면 생목과 재생목을 적당한 비율로 섞어 재배할 경우 비용 절감과 환경보호 차원에서 유용한 방법으로 사료된다.

  • Background: Although Gastrodia elata contains the valuable, bio-active compounds gastrodin and 4-hydroxybenzyl alcohol (4-HBA), it also contain ρ-cresol, which is a major source of an objectionable pig slurry-like odor. Accordingly, this study was performed to determine the deodorization effect of Diaion HP-20 resin on a G. elata extract. Methods and Results: Using Diaion HP-20 with an increasing concentration of ethanol, an extract of G. elata was fractionated into 15 fractions, which were anlayzed to determine their concentrations of active compounds and ρ-cresol. The gastrodin, 4-HBA, total phenolics, and ρ-cresol concentrations of the G. elata extract were 403.13, 408.15, 2,476.09, and 11.77 ㎍/㎖, respectively. Among the different fractions, gastrodin and 4-HBA were detected in fractions 3 to- 6, and 4 to- 10, respectively whereas total phenolics were detected in all samples, with fractions 5 to- 7 being characterized by higher concentrations than were the other fractions. ρ-Cresol was detected in fractions 12 to- 15, at concentrations ranging from 0.39 ㎍/㎖ to 6.05 ㎍/㎖ with the highest concentration detected in fraction 14. The fractions containing ρ-cresol could be selectively separated from the G. elata extract without the loss of major bio-active compounds such as gastrodin and 4-HBA. Conclusions: The results of this study indicate that a deodorizing method using Diaion HP-20 resin can be considered for improving the sensory qualities of G. elata extract without a loss of the major bio-active compounds.
