SSRs were successfully isolated from the Perilla crop in our current study, and used to analyze Perilla accessions from East Asia. Analyses of the clear genetic diversity and relationship for Perilla crop still remain insufficient. In this study, 40 new simple sequence repeat (SSR) primer sets were developed from RNA sequences using transcriptome analysis. These new SSR markers were applied to analyze the diversity, relationships, and population structure among 35 accessions of the two cultivated types of Perilla crop and their weedy types. A total of 220 alleles were identified at all loci, with an average of 5.5 alleles per locus and a range between 2 and 10 alleles per locus. The MAF (major allele frequency) per locus varied from 0.229 to 0.943, with an average of 0.466. The average polymorphic information content (PIC) value was 0.603, ranging from 0.102 to 0.837. The genetic diversity (GD) ranged from 0.108 to 0.854, with an average of 0.654. Based on population structure analysis, all accessions were divided into three groups: Group I, Group II and the admixed group. This study demonstrated the utility of new SSR analysis for the study of genetic diversity and population structure among 35 Perilla accessions. The GD of each locus for accessions of cultivated var. frutescens, weedy var. frutescens, cultivated var. crispa, and weedy var. crispa were 0.415, 0.606, 0.308, and 0.480, respectively. Both weedy accessions exhibited higher GD and PIC values than their cultivated types in East Asia. The new SSR primers of Perilla species reported in this study may provide potential genetic markers for population genetics to enhance our understanding of the genetic diversity, genetic relationship and population structure of the cultivated and weedy types of P. frutescens in East Asia. In addition, new Perilla SSR primers developed from RNA-seq can be used in the future for cultivar identification, conservation of Perilla germplasm resources, genome mapping and tagging of important genes/QTLs for Perilla breeding programs.

Perilla (Perilla frutescens Britton var. Crispa Decasne) cultivated in three geographical areas of Korea, Gwangju, Taegu and Jeju, was analyzed for carbohydrate, lipid, protein, inorganic components and fatty acid composition. Carbohydrate, lipid and protein content of perilla seed ranged from 40 (Taegu) to 44% (Jelu), from 28 (Jeju) to 34% (Taegu) and from 15 (Gwangju) to 16% (Jeju), respectively. The overage contents of potassium, silicate, calcium, phosphate, iron, zinc, magnesium and mangane in the perilla seed varied between $426{\sim}446$, $197{\sim}229$. $124{\sim}136$, $46{\sim}56$, $30{\sim}49$, $42{\sim}45$, $40{\sim}45$, and $30{\sim}36mg%$, respectively and those variations different cultivation areas were not significant except iron. Saponification number, iodine value and acid value of the perilla oil were between $194{\sim}198$, $196{\sim}200$ and $4{\sim}5$, respectively. Those variations among the cultivation areas were not significant. The composition of the perilla oil was observed to be composed of $92{\sim}95%$ of triglyceride, $1.2{\sim}1.3%$ of phospholipid, $1.7{\sim}1.9%$ of unsaponifiables, $0.7{\sim}0.9%$ of free fatty acid, and $1.1{\sim}1.4$ linolenic, linoleic and oleic acid as $55{\sim}56$, $16{\sim}18$ and $16{\sim}20%$ of total fatty acids, but in phospholipid, the content of saturated fatty acids, $12{\sim}24$ of total fatty acid, was higher than that in triglyceride, $8{\sim}19%$ of total fatty acids. The content of saturated fatty acids in sterylester $(14{\sim}19%)$ was higher than that in sterylglycoside ($6{\sim}7%$ of total fatty acids). The variation in fatty acid composition was not significant in the composition of total fatty acid but a significant difference was observed in the composition of phospholipid, in which the content of palmitate ranged from 11.8%(Taegu) to 24%(Gwangju) of total fatty acids. No significant variation was found in the fatty acid composition among the cultivation areas, while a significant difference was observed in phospholipid.

The effect of hot water and methanol extracts of 9 species from Korean mushrooms (Fomitopsis pinicola, Fomitella traxinea, Codyceps militaris, Phellinus linteus, Coriolus versicolor, Sparassis crispa, Ganoderma lucidum, Fomes fomentarius, Agaricus blazei) on the growth of Helicobacter pylori were examined using a Mueller-Hinton agar diffusion method. Hot water ($121^{\circ}C$) extracts from fruit bodies of F. traxinea, C. militaris, P. linteus, C. versicolor and F. pinicola showed $10{\sim}15\;mm$ inhibition zone against H. pylori. Methanol extracts of F. pinicola showed 44 mm inhibition zone, but another extracts showed no inhibition. Early fractions of DEAE-Sephadex A-25 column chromatography of methanol extracts from F. pinicola showed high inhibition activity against H. pylori.

Mushroom have long been valued as highly nutritious and tasty foods in many societies throughout the world. It is known for biological activities including anti-inflammatory and anti-oxidative potential. However little is known about anti-cancer property. In this study, we investigated the anti-prostate cancer activity of mushrooms. For that, eight kinds of mushrooms such as, T. matsutake, S. crispa, G. lucidum-US, G. lucidum-AS, C. cardinalis-BR, G. frondosa, P. linteus, U. esculenta were extracted with hot water. Among them, three kinds of mushrooms including T. matsutake, G. lucidum-US and C. militaris-BR extracts inhibited prostate specific antigen (PSA) expression in prostate cancer cell, LNCaP. These results demonstrate that some of mushrooms inhibited PSA expression suggesting that the mushrooms might be a candidate for the treatment of prostate cancer.

Glucan has been shown to have a significant role in the activation of the immune system, including increased activity of macrophages and so on. Sparassis latifolia (formerly S. crispa) is an edible mushroom abundant in dietary fiber and widely known to contain high levels of ${\beta}$-glucan. In the present study, fermentation broths containing soluble ${\beta}$-glucan were prepared by fermentation with mushrooms with four Lactobacillus species (L. plantarum subsp. Plantarum, L. acidophilus, L. helveticus, and L. delbrueckii subsp. Bulgaricus). After culturing four Lactobacillus spp. in MRS broth, each Lactobacillus was inoculated into MRS broth containing S. latifolia powder 5% (w/v) at $37^{\circ}C$ in an anaerobic incubator for five days. It showed that the ${\beta}$-glucan contents were different in each fermentation sample. The suitable conditions for the preparation of mushroom fermentation broths were investigated and discussed.

The purpose of this study was to investigate the antioxidative and anti-inflammatory activities of ethanol extracts from Perilla frutescens var. acuta by varying the concentration of ethanol at 30, 50, 70, and 90% to utilize the effective extract of Perilla frutescens as a cosmetic and pharmaceutical material. In the DPPH antioxidant activity test, the 70% ethanol extract showed the highest activity with an IC50 of 680.98ppm. ABTS showed a high activity in the 50% ethanol extract and the 70% ethanol extract with an IC50 of 646.94 and 661.94 ppm, respectively. Each ethanol extract showed antioxidant activity at a certain concentration (100-10000 ppm), but did not show any significant relationship with the ethanol extract concentration. In RAW 264.7 macrophages induced by LPS, each of the ethanol extracts showed reduced NO production in all extracts, and more than 50% ethanol extract (10000ppm) inhibited nitric oxide formation by 85% or more. In particular, the 70% ethanol extract showed 90% or more nitric oxide production inhibition. In addition, the MTT assay showed no cytotoxicity at all concentrations (1250-10000 ppm) of each extract. In this study, the ethanol extract of Perilla frutescens var. acuta has antioxidant activity and anti-inflammatory activity that is dependent on the concentration at each extraction concentration.
