This study was designed to investigate the inhibitory effects of Perilla frutescens (L.) Britton var. frutescens extract on the production of inflammation-related mediators (NO, ROS, NF-${\kappa}B$, iNOS and COX-2) and pro-inflammatory cytokines (TNF-${\alpha}$, IL-$1{\beta}$, IL-6) in lipopolysaccharide-stimulated RAW 264.7 macrophages. Perilla frutescents (L.) Britton var. frutescens was air-dried and extracted with ethanol. The extract dose-dependently decreased the generation of intracellular reactive oxygen species and dose-dependently increased antioxidant enzyme activities, such as superoxide dismutase, catalase and glutathione peroxidase in lipopolysaccharide stimulated RAW 264.7 macrophages. Also, Perilla frutescens (L.) Britton var. frutescens extract suppressed NO production in lipopolysaccharide-stimulated RAW 264.7 cells. The expressions of pro-inflammatory cytokines (TNF-${\alpha}$, IL-$1{\beta}$ and IL-6), NF-${\kappa}B$, iNOS and COX-2 were inhibited by the treatment with the extract. Thus, this study shows the Perilla frutescens (L.) Britton var. frutescens extract could be useful for inhibition of the inflammatory process.

In this study, we established an in vitro regeneration system to maximize the recovery of leafy perilla (Perilla frutescens L. Britton) plantlets as part of developing a molecular biotechnology-based metabolic engineering program for this crop plant. Hypocotyl segments including the apical buds were used as explants for the direct production of shoots without an interim callus phase. The number of shoots produced from the apical buds peaked within 3-4 weeks, and the shoots were subsequently cultured on Murashige and Skoog (MS) media supplemented with 2 mg $1^{-1}$ benzylaminopurine (BA). Spontaneous rhizogenesis was observed after 7-10 days of culture on MS media without hormonal additives. The rooted shoots developed into normal plants in soil after hardening on distilled water for 3-4 days. The average plantlet regeneration frequency was higher for the apical buds (64.33%) than for the top (15.66%), middle (4%), and basal (1.33%) segments of the hypocotyls. This regeneration system demonstrates a capacity for high-frequency plantlet recovery and thus should be considered for use in the genetic manipulation of leafy perilla.

This study developed an HPLC analysis method for the determination of isoegomaketone (IK) and perillaketone (PK) in Perilla frutescens (L.) Britton leaves. P. frutescens ethanol extract was optimized through an HPLC analysis using a C18 column ($250{\times}4.6mml$, D, $S-5{\mu}m$, 12 nm) with gradient elution of water and acetonitrile as the mobile phase at a flow rate of 1 mL/min and a UV detection wavelength of 254 nm. The results of this method showed linearity in the calibration curve at a coefficient of correlation ($R^2$) of IK 0.9995, PK 0.9998. The limits of detection (LOD) for IK and PK were $0.234{\mu}g/mL$ and $0.952{\mu}g/mL$. The limits of quantification (LOQ) for IK and PK were $0.017{\mu}g/mL$ and $0.043{\mu}g/mL$. The inter-day precision RSDs of IK and PK in the P. frutescens were 1.25 to 2.69% and 0.36 to 1.10%, respectively, and the intra-day precision RSDs of IK and PK were 0.96 to 2.51% and 0.90 to 1.93%, respectively. The accuracies of IK and PK were 96.31 to 97.92% and 101.26 to 105.14%. In conclusion, this method was applied successfully to the detection of IK and PK in P. frutescens.

The purpose of this study was to analyze the chemical components of Perilla leaf(frutescens Britton var. scuta Kudo) according to the making process, and to examine Hunter's color value and sensory evaluation of Jasosuksu by extraction time. Perilla leaves were prepared in three types; fresh leaf, dried leaf in the shade and roasted leaf after being dried in the shade in order to make Jasosuksu. The results of the research were as follows: Free sugars(sucrose, glucose, fructose) and organic acids(citric acid, tartaric acid, malic acid, succinic acid) were present in the fresh leaf, dried leaf and roasted leaf. $15{\sim}16$ kinds of amino acid including aspartic acid were determined in the fresh leaf, dried leaf and roasted leaf, and the major free amino acids were serine, aspartic acid, and glutamic acid. The major total amino acids of tile fresh leaf, dried leaf and roasted leaf were glutamic acid, histinine, and glycine. The major fatty acids of Perilla leaves were palmitic acid, linolenic acid, and linolenic acid. The content ratio of linolenic acid in fresh leaves was the highest, but that of palmitic acid was lower than that of dried leaves and roasted leaves. L value, a value, and b value of Perilla leaf were the highest in the roasted leaves followed by the order of dried leaves and fresh leaves. L value and b value of Jasosuksu extracted from roasted leaves were higher than Jasosuksu extracted from dried leaves. The preference of color, flavor, sweetness of Jasosuksu extracted from dried leaves was the highest when extraction time was 10 min. at $70^{\circ}C$, but that of Jasosuksu extracted from roasted leaves was the highest when extraction time was 15 min. at $70^{\circ}C$. The preference of color, flavor, taste of Jasosuksu extracted from roasted leaves was higher than that of Jasosuksu extracted from dried leaves.

We studied the antimicrobial activities of five compounds isolated from the stems of Vitis coignetiae Pulliat and the seeds of Perilla frutescens (L.) Britton. Based on spectroscopic evidence, compounds 1 to 5 were characterized as resveratrol, $\varepsilon$-viniferin, ampelopsin E, apigenin, and luteolin, respectively. The antimicrobial activities against Gram-positive (Staphylococcus aureus) and -negative (Pseudomonas aeruginosa) bacteria and a fungus (Candida albicans) were investigated using the disc diffusion and broth dilution methods. C. albicans was not inhibited by the five compounds. Compounds 2 and 5 had significant anti-microbial activity against S. aureus, and the 50% inhibitory concentration ($IC_{50}$) of compound 2 against S. aureus was 7.2 ${\mu}M$. Compounds 4 and 5 significantly inhibited P. aeruginosa and the minimum inhibitory concentration (MIC) of compounds 2 and 5 was 0.07 and 2.0 ${\mu}M$, respectively. Compounds 2, 4, and 5 had strong anti-microbial activity against S. aureus and P. aeruginosa.

Perilla frutescens Britton var. acuta Kudo, an annual plant primarily cultivated in China, Japan, and Korea, has been used as a traditional medicine to treat inflammatory diseases, depression, and many anxiety-related disorders. Previously, we reported the inhibitory effects of n-hexane layer of P. frutescens var. acuta extract against beta-amyloid (Aβ) aggregation, and the isolation of asarone derivatives as active constituents from n-hexane layer. In this study, dichloromethane layer of P. frutescens var. acuta was applied to bioassay-guided isolation methods accompanied with Thioflavin T (Th T) fluorescence assay to investigate the inhibitory effect on Aβ aggregation and disaggregation. As the results, three triterpenoids including ursolic acid (1), tormentic acid (2) and corosolic acid (3) were isolated. All compounds reduced Aβ aggregation and increased disaggregation of preformed Aβ aggregates in a dose-dependent manner. However, the inhibitory effect of three compounds on Aβ aggregation was not correlated with antioxidant activity, which was measured by DPPH assay. Taken together, these results suggest that the triterpenoid derivatives from P. frutescens have the potential to be developed as good therapeutics or preventatives for AD.

BACKGROUND/OBJECTIVES: Perilla frutescens Britton leaves are a commonly consumed vegetable in different Asian countries including Korea. Cancer is a major cause of human death worldwide. The aim of the current study was to investigate the inhibitory effects of ethanol extract of perilla leaf (PLE) against important characteristics of cancer cells, including unrestricted growth, resisted apoptosis, and activated metastasis, using human cancer cells. MATERIALS/METHODS: Two human cancer cell lines were used in this study, HCT116 colorectal carcinoma cells and H1299 non-small cell lung carcinoma cells. Assays using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide were performed for measurement of cell growth. Soft agar and wound healing assays were performed to determine colony formation and cell migration, respectively. Nuclear staining and cell cycle analysis were performed for assessment of apoptosis. Fibronectin-coated plates were used to determine cell adhesion. RESULTS: Treatment of HCT116 and H1299 cells with PLE resulted in dose-dependent inhibition of growth by 52-92% (at the concentrations of 87.5, 175, and $350{\mu}g/ml$) and completely abolished the colony formation in soft agar (at the concentration of $350{\mu}g/ml$). Treatment with PLE at the $350{\mu}g/ml$ concentration resulted in change of the nucleus morphology and significantly increased sub-G1 cell population in both cells, indicating its apoptosis-inducing activity. PLE at the concentration range of 87.5 to $350{\mu}g/ml$ was also effective in inhibiting the migration of H1299 cells (by 52-58%) and adhesion of both HCT116 and H1299 cells (by 25-46%). CONCLUSIONS: These results indicate that PLE exerts anti-cancer activities against colon and lung cancers in vitro. Further studies are needed in order to determine whether similar effects are reproduced in vivo.
