Background : Alpha-linolenic acid is a type of omega-3 fatty acid and has been reported to be found at a remarkably high content in seeds of perilla (Perilla frutescens). The purpose of this study was to investigate the fatty acid compositions in 45 perilla accessions collected from Russia and recommend the potential genetic resources related to their fatty acid compositions. Methods and Results : The 45 accessions of perilla seeds which were collected from Russia were used for the study. Perilla seed oil was recovered using hexane in a soxhlet extraction method. The fatty acid compositions were analyzed using gas chromatography. The total oil content was ranged between 28.39 and 46.89%. The compositions of palmitic, stearic, oleic, linoleic and linolenic acid ranged from 5.57 to 7.09%, 1.16 to 2.27%, 11.83 to 19.55%, 11.92 to 16.71%, and 59.19 to 67.28%, respectively. Cultivars 'Dayu', 'Daeyu' and 'Anyu' showed lower linolenic acid composition compared to the average value of linoleic acid in perilla germplasms collected from Russia. Cluster analysis based on the fatty acid composition of the 45 perilla accessions segregated into three groups. Group Ⅰ characterized as higher palmitic, stearic and oleic acid compositions compared to other groups. Group Ⅱ which contained 12 accessions had high total oil and linoleic acid composition. Group Ⅲ characterized as a higher linolenic acid composition compared to other groups (p < 0.001). Oleic acid showed a significant negative correlation (r = -0.825) with linolenic acid. Principal component analysis (PCA) revealed that the first two principal components together explained 74.4% total variation. Conclusion : Our results indicated that accessions IT235818, IT235820, IT226739 which exhibited high linolenic acid composition could be useful to develop new functional vegetable oil materials.

Background : D. lablab is tropical vine grown as a garden annual belonging to Leguminosae, which is used in oriental medicine for coldness like a cooling disease, diarrhea and abdominal pain etc. when it is hot weather in summer and plenty of rainy seasons. In previous study, D. lablab showed an inhibitory activity for trypsin. Reactive oxygen species (ROS) was produced by trypsin via a second protease-activated receptor. Therefore, it is considered that there are substances having antioxidant activity in D. lablab. Methods and Results : The seed of dried D. lablab was extracted hot water, and then partitioned with Et2O, EtOAc, n-butanol and aqueous. The aqueous layer was separated from silica gel and Diaion HP-20 liquid chromatography and HPLC-prep, resulting in confirmed two compounds. The two compounds was identified to C14H14N2O4 and stachyose from ESI-MS and 1H- and 13C-NMR. The two compounds was performed the intracellular ROS measurement and the expression of catalase and Cu/Zn SOD. The intracelluar ROS measurement was detected using DCF-DA in LPS-treated RAW264.7 cell. The results were shown that two compounds inhibited intracellular ROS levels to dose-dependent. And the expression of genes was detected quantitative real-time PCR in LPS-trated RAW264.7 cell. Although the two compounds were not significantly different towards the Cu/Zn SOD expression level, the expression level of catalase genes were indicated an increase rate of about 347% in C14H14N2O4 and about 242% in stachyose at 50 ㎍/㎖ compared with LPS-not treated cells. Conclusion : From the above results, both compounds significantly shown antioxidant activity in dose-dependent by examining the amount of intracellular ROS and the expression levels of SOD and catalase enzymes. As screening ROS inhibition of C14H14N2O4 and stachyose in vitro, they may be a good candidate for regulating the progression of human oxidant stress diseases and warrants further studies.

Background : Rehmannia glutinosa (RG) has been utilized as a traditional medicine in Asia. However, the development of varieties is limited and the climate is changing gradually. Therefore, it is required to develop a superior lineage suitable for this. So we have secured several species, and it is necessary to confirm the cytotoxicity of various kinds of cells for its safety and to secure safety for further utilization. Methods and Results : 11 cultivars and 21 lineages of RG were collected from Rural Development Administration (RDA) at Eumseong of Chungcheongbuk-do and national farmhouse. They were cultivated in test-research farm in RDA and used as materials. Human (THP-1 cell, human leukemia monocytic cell line) and rodent-derived immune cells (RAW264.7, murine monocyte/macrophage cell line) and hepatocytes (HepG2, human liver cell line) were used to assess cytotoxicity. Cytotoxicity was determined by using MTT assay. As a result of evaluation of cytoxicity, 11 cultivars and 21 lineages of RG were not shown cytotoxicity range from 250 - 1,000 ㎍/㎖ concentration in THP-1 cell, RAW264.7 cell and HepG2 cell. Conclusion : Development of RG with superior lineage suitable for changing climate is required. We selected a good lineage (21 ea), and result of the cytotoxicity evaluation from low to high concentrations in immune- and liver-derived cells, there was no toxicity at all. Therefore, if these excellent lineages are distributed to farmers, they can help farmers. And it can help research on immunity and liver function in the future.

Background : Domestic use of cosmetics has largely been dependent on imports for the opening of cosmetics raw materials, but research has been progressing actively on natural ingredients to develop new materials. Methods and Results : The extracts of hot–water and ethanol extracts from Stachys sieboldii were tested cytotoxicity, inhibition of melanin biosynthesis and NO production activity. The cytotoxicity of the hot water extract of S. sieboldii were 98.4, 95.0, 93.9 and 90.6%, respectively, when treated with 10, 50, 100, 500 ㎍/㎖. Cytotoxicity of S. sieboldii ethanol extract was 97.1, 95.3, 94.6 and 94.4%, respectively, at the concentrations of 10, 50, 100 and 500 ㎍/㎖. Melanin biosynthesis inhibitory effect of α-MSH at 100 μM increased to 118.1% in melanin, but decreased to 92.3% in S. sieboldii ethanol extract. NO production inhibition increased to 109.2% when treated with LPS and was 103.3% at 500 ㎍/㎖ of hot water extract and 105.9% at 500 ㎍/㎖ of ethanol extract of S. sieboldii. Conclusion : The ethanol extract of S. sieboldii did not showed the cytotoxicity, and reduce NO production. Therefore, ethanol extract of S. sieboldii had an potentials for developing whitening cosmetics.

Background : Brain waves are generated by the neurons in the brain. Many scientists fixed the electrodes of the electroencephalogram (EEG) on the scalp to record the signal expression of continuous cerebral activity. EEG is widely used in clinical diagnosis. It can be used to screen epilepsy, depression, ementia, stroke, encephalitis, ADHD and other brain diseases. Also, many local and foreign studies on aromatherapy focused on the discussion of human skin absorbing essential oils. This study discusses the level of relaxation efficacy of inhaled essential oils via the human olfactory organs. Thus, this study intended to observe the effects of essential oil of Aucklandiae Radix and Cyperi Rhizoma on EEG activity. Methods and Results : We evaluated the effects of essential oil of Aucklandiae Radix and Cyperi Rhizoma, on human EEG activity. For this purpose, essential oil was extracted from Aucklandiae Radix and Cyperi Rhizoma by the supercritical extraction method. The effect of its inhalation on EEG activity was evaluated by measuring the EEG power spectrum in 20 healthy participants. EEGs signals were recorded using QEEG-8 system (LAXTHA Inc., Daejeon, Korea) from 8 grounding electrodes. The subjects were instructed to sit quietly, close their eyes and to breathe normally during the measurement. The fragrance stimulus was dipped in a paper (14 ㎝2) then placed about 3 cm in front of the subject's nose. EEG was recorded before and during the fragrance exposure for 30 seconds. The mean power values (μV) calculated for fast fourier transform (FFT) analysis indicators. The results were as essential oils of Aucklandiae Radix and Cyperi Rhizoma decreased the overall brain relative theta (θ waves), but increased relative beta (β waves), absolute gamma (γ waves), spectral edge frequency (SEF) and spectral edge frequency 95% (SEF95). Conclusion : The changes in the EEG activities following inhalation of Aucklandiae Radix and Cyperi Rhizoma suggest that the oil can improve psychological well-being by increasing attention and relaxation.
