  • This Experimental study was done to research effects of Fagopyrum esculentum Moench(Me-mil) Extract on the anti-allergic effects. The results were obtained as follows : 1. All concentrations of Fagopyrum esculentum Moench Extract(Flours and seeds) inhibit histamine release under the vascular permeability response to intracutanenous injection. The result is proportion to concentration. But, rutin can't get considerable result. 2. All concentrations of Fagopyrum esculentum Moench Extract inhibit histamine release under the vascular permeability response to intraperitoneal injection of SD Rat in comparison with Diphenhydramine which is typical anti-histamine drug. 3. All concentrations of Fagopyrum esculentum Moench Extract inhibit histamine release under the vascular permeability response to per-oral during the three or five days. 4. In the result of quantification of histamine induced Compound $\frac{48}{80}$, Flours and seeds of Fagopyrum esculentum Moench Extract inhibit histamine release. 5. Among the fracination of Fagopyrum esculentum Moench Extract, $CHCl_3$ fraction inhibit histamine release effectively. 6. In the result of genetic manifestative inhibition about the Human mast cell treated PMA and A23187, Fagopyrum esculentum Moench Extract effect in the IL-4 and TNF-${\alpha}$ except IL-5. According to the above results, it is suggested that Fagopyrum esculentum Moench(Me-mil) Extract has anti-allergic effect.

  • The aim of this study was to investigate the effect of ethanol extract of Fagopyrum esculentum on the melanogenesis. To determine whether ethanol extract of Fagopyrum esculentum suppress melanin synthesis in cellular level, B16F10 melanoma cells were cultured in the presence of different concentrations of Fagopyrum esculentum ethanol extract. In the present study, we examined the effects of Fagopyrum esculentum ethanol extract on cell proliferation, melanin contents, tyrosinase activity, expression of melanogenic enzyme proteins including tyrosinase, tyrosinase-related protein 1 (TRP-1) and tyrosinase-related protein 2 (TRP-2). Cell proliferation was slightly increased by treatment with ethanol extract of Fagopyrum esculentum $(25-200 {\mu}g/m{\ell}).$ The ethanol extract of Fagopyrum esculentum effectively suppressed melanin contents at a dose of $100 {\mu}g/m{\ell}).$ It was observed that the color of cell pellets was totally whitened compared with the control. The ethanol extract of Fagopyrum esculentum inhibited tyrosinase activity, regulate melanin biosynthesis as the key enzyme in melanogenesis. Using western blot analysis, the ethanol extract of Fagopyrum esculentum dose-dependently decreased tyrosinase and TRP-1 protein levels, and tyrosinase and TRP-1 were detected in similar manner. ${\alpha}-MSH$ leads to a stimulation of melanin synthesis through increase of tyrosinase activity, melanin contents and cytoplasmic dendricity. In this study, ethanol extract of Fagopyrum esculentum down-regulated the ${\alpha}-MSH$-induced tyrosinase activity, melanin contents and cytoplasmic dendricity. Regarding protein levels of the melanogenic enzymes, the amounts of tyrosinase and TRP-1 was increased after incubation with a-MSH. The treatment of ethanol extract of Fagopyrum esculentum decreased the ${\alpha}-MSH$-induced expression levels of tyrosinase and TRP-1. These results suggest that the ethanol extract of Fagopyrum esculentum exerts its depigmenting effects through the suppression of tyrosinase, TRP-1 and cytoplasmic dendricity. And it may be a potent depigmetation agent in hyperpigmentation condition.

  • The rutin content of Fagopyrum tataricum is 100-fold higher than that of Fagopyrum esculentum. For the development of a rutin-containing beverage, a suitable method to extract rutin from buckwheat (Fagopyrum tataricum) with high rutin yield was investigated. A roasting temperature range of $310/240^{\circ}C$ (Ed-confirm that this is indeed a range; otherwise perhaps, 'Roasting temperatures ranging from 310 to $240^{\circ}C$ were considered$\ldots$') was considered to be the best as the basic color reference. Rutin content varied according to the roasting time and heating temperature; i.e., it decreased with increasing roasting time and temperature. (Ed- this sentence is unnecessarily complicated and should be simplified to 'Rutin content decreased with increasing roasting time and heating temperature.') The optimal extraction temperature and processing time were obtained as $80^{\circ}C$ and 10 minutes to maximize the rutin concentration in the extract.

  • 아연 폐광지 부근의 논토양에서 메밀(Fagopyrum esculentum)을 이용한 식물상추출공법 적용 전후에 대해 토양 내 아연 형태 및 탈수소효소활성도 변화를 조사하였다. 메밀을 식재한 논토양은 아연농도는 약 600 mg/kg인 고오염 구역과 약 300 mg/kg인 저오염 구역으로 구분되었다. 메밀을 재배한 결과, 메밀은 고농도 구역에서 아연에 의한 성장 저해를 입었으나 토양으로부터 식물유효성 형태의 아연을 흡수하여 식물체내에 축적하였고, 아연 독성으로 저해된 토양 내 탈수소효소활성도를 증가시킨 것으로 나타났다. 2개월 동안 메밀을 재배한 후 근권 토양 내 식물유효성 아연 농도는 고오염 구역에서 약 25% 감소, 저오염 구역에서 약 70% 감소하였다. 근권 토양에서 감소한 식물유효성 아연의 양은 식물체내에 축적된 아연의 양과 유사하여(Recovery 92$\sim$107%), 메밀이 토양 내 식물유효성 아연을 제거 및 축적하였음을 알 수 있었다. 또한 토양 내 총 아연 농도와 토양 탈수소효소활성도는 음의 상관관계를 가진 것으로 나타났으며, 초기에 고오염 토양에서는 저오염 토양에 비하여 토양 탈수소효소활성도가 약 2배 저해되었지만 메밀 재배 후 각각의 근권에서 약 35% 증가한 것을 확인하였다.

  • Phytochemical constituents were isolated from the seeds of tartary buckwheat (Fagopyrum tataricum) by open column chromatography. Their structures were elucidated as ${\beta}$-sitosterol (1), ${\beta}$-sitosterol-3-O-glucoside (2), oleanolic acid (3), kaempferol (4), quercetin (5), kaempferol-3-O-rutinoside (6), and quercetin-3-O-rutinoside (7) on the basis of spectroscopic analysis including $^1H$-, $^{13}C$-NMR, and MS. To our knowledge, oleanolic acid (3) has been isolated for the first time from the seeds of Fagopyrum species. The total contents of compounds 4 - 7 were 0.500 mg/g in Daesan maemil, 0.312 mg/g in Yangjul maemil, and 2.185 mg/g in tartary buckwheat.

  • The inhibitory effect of the aerial parts of Fagopyrum esculentum on the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical was examined. The n-butanol fraction from the methanol extract of title plant showed stronger inhibitory effect than other fractions on DPPH radical. Two flavonoids were isolated from n-butanol fraction having the potent activity and elucidated as quercetin-3-O-${\alpha}$-L-rhamnoside and quercetin-3-O-rutinoside on the basis of spectral evidence. The $IC_{50}$ values of these compounds on DPPH radical were 6.56 ${\mu}M$ and 8.37 ${\mu}M$, respectively.

  • At the different growing stages of Fagopyrum esculentum Moench planted at the green house and out doors, the contents of free amino acids in the whole plants,were determined quantitatively by spot-extract colorimetric method (J. Awapara method) using the chromatograms obtained by the ion-exchange resin and paper chromatographic method. And the contents of carbohydrate in the whole plant were determined by Bertrand method. The results were summarized as follows. 1. Almost same kinds of free amino acids were detected in the both plants. 2. Concentrations of most amino acids was increased progressively during growth; further growth was accompanied by decreased concentrations. 3. Rate of growth and increasing of total amino acid content of green house plant is greater than that of out dorrs plant. 4. At the same stages of gwoth, total free amino acid content of green house plant is higher than that of out doors plant but sugar content is lower. 5. There was rapidly increasing of sugar content and decreasing of total free amino acid content except asparagine during mature of seeds.
