Callus was derived from the leaves of Perilla frutescens var. acuta which is commonly cultivated in Korea. It has been found that the light decreased the growth rate of the callus but rather increased the contents of essential oils. The addition of one ppm of 1-naphthyl acetic acid and 5ppm of kinetin in the medium caused the increased production of essential oils.

The natural dyeing of cotton fabric with Perilla frutescens var. acuta extract was investigated. The proper extraction temperature and time were $100^{\circ}C$ and 120 minutes. The proper temperature, time and colorant powder concentration for the dyeing of cotton fabric with Perilla frutescens var. acuta powder were $90^{\circ}C$, 60 minutes and 15%(o.w.b.), respectively. In various mordanted methods, the K/S values of simultaneous-mordanted methods were higher than those of pre-and post-mordanted methods. And the Cu-and Fe mordant showed higher K/S values than those of other mordants. Light colorfasness of mordanted cotton fabric was poor, but the other colorfasnesses were shown to be good. The cotton fabric mordanted with Cu mordant was showed effective bacterial reduction.

우리나라의 고유한 향신료로 활용되고 있는 소엽의 휘발성 향기성분 분석에 적합한 solid phase microextraction(SPME) fiber를 선정하기 위하여 carboxen/polydimethylsiloxane(CAR/PDMS)과 polydimethylsiloxane(PDMS)의 2종류 fiber를 이용하여 향을 추출한 후 GC/MS로 분석하였다. CAR/PDMS fber에 소엽의 향을 흡착시켜 분석한 결과, 39종의 성분이 확인되었으며, PDMS fiber를 이용하였을 때는 20가지의 향기성분이 확인되었다. 특히 PDMS fiber를 사용하였을 때 CAR/PDMS fber를 이용하였을 때 보다 perillaldehyde (40.50%), limonene (27.32%), E,E-,${\alpha}-famesene$ (10.22%) 및 ${\beta}-caryophyllene$ (8.02%)의 소엽의 주요 향기성분이 선택적으로 많이 확인되었다. 따라서 방향성 식용식물인 소엽의 향기를 SPME법으로 추출할 때는 PDMS fiber가 적합하다고 판단된다.

We determined the inhibitory activity of the essential oil fraction obtained by steam distillation from the fresh and dried leaves of Perilla frutescens var. acuta against some pathogenic Salmonella and Vibrio spp. The activities of compounds isolated from the essential oils, apiol and myristicin, were also tested and the results were compared with those of the essential oil fraction. The Perilla essential oil fraction and its main components showed significant inhibition against antibiotic-susceptive and antibiotic-resistant strains of the tested Salmonella and Vibrio strains. Synergistic or additive effects were identified by combing the oils with ampicillin by checkerboard-titer tests. We conclude that essential oils from P. frutescens can be useful in the treatment of Salmonella and Vibrio infections and as safe additives to food materials for the prevention of contamination of food by these bacteria. This is especially important because of the rapid increase in antibiotic-resistant strains, which could cause severe symptoms in humans.

Morphological variation between cultivated and weedy types of Perilla frutescens var. frutescens and P. frutescens var. crispa were studied in 327 germplasm by examining 17 morphological characters. The germplasm between the two varieties were varied for their qualitative and quantitative characters. The seed coat color of cultivated P. frutescens var. frutescens is commonly light brown and brown while deep brown color was observed in the weedy type P. frutescens var. frutescens and P. frutescens var. crispa. The leaf size, cluster length, plant height, flower number per cluster and seed weight in cultivated P. frutescens var. frutescens were significantly (P<0.05) different from weedy type P. frutescens var. frutescens and P. frutescens var. crispa. The cultivated P. frutescens var. frutescens exhibited significantly higher plant height (158.6 cm) compared to the weedy P. frutescens var. crispa (133.8 cm). Likewise, seed weight was significantly higher in cultivated (1.9 g) than in the weedy type of P. frutescens var. frutescens (1.6 g) and P. frutescens var. crispa (1.4 g). Principal component analysis (PCA) result showed that the first and second principal component cumulatively explained 86.6% of the total variation. The cultivated type P. frutescens var. frutescens and its weedy accessions were not clearly separated with P. frutescens var. crispa by PCA. Hence it requires the use of molecular markers for better understanding of their genetic diversity.

The study examined the preference and style of consumption of perilla leaves(Perilla frutescens var. japonica Hara), a popular food item in Korea, by consumers in the Daejeon area. Of the respondents 35.2% purchased perilla leaves in a large super-market limited to two to three bundles. Comsumer preferences were to consume the leaves raw or pickled with salt or soy sauce, or use as a fish soup ingredient. The majority of consumers aged 20~29-years-of age preferred to wrap sashimi with perilla leaves. As a side dish, regardless of age, consumers preferred to pan-fried perilla leaves with mincedmeat and perilla leaves.

The Korean daily intake of vegetable oils has increased about 2.5-fold from 17 g/day to 46 g/day for the last several decades. Perilla (Perilla frutescens var. frutescens) has been cultivated in Korea for a long time as a dietary oil seed which has the highest content of ${\alpha}$-linolenic acid, accounting for nearly 60%. It is known that the main role of ALA is as a precursor to the longer-chain ${\omega}-3$, eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA), the metabolic products of ${\alpha}$-linolenic acid (ALA, ${\omega}-3$). Dietary ${\omega}-3$ fatty acids reduce inflammation and the risk of chronic diseases such as heart disease, cancer, and arthritis, but they also may act as functional components for cognitive and behavioral function. Thus, ${\alpha}$-linolenic acid is one of the essential nutrients in modern dietary patterns in which much linoleic acid is consumed. Nevertheless, perilla oil, rich in ${\alpha}$-linolenic acid, can be easily oxidized, giving rise to controversies with respect to shelf life, the deterioration of the product's commercial value, and further related toxicity. Recent research using genetic modifications has tried to develop new plant oil seeds that balance the ratio of ${\omega}-6/{\omega}-3$ fatty acids. Such trials could be a strategy for improving an easily oxidizable property of perilla oil due to high ${\alpha}$-linolenic acid. Alternatively, appropriate application of antioxidant to the oil can be considerable.

To better understand the morphological variation for Perilla crop in different areas of China, we studied the morphological variation in 87 accessions (84 cultivated var. frutescens and three cultivated var. crispa) from high latitude (Northeast China) and middle latitude (North and Northwest China) areas of China by examining seven quantitative and 10 qualitative characters. Analysis of the morphological variation determined that there was significant morphological differences in five quantitative traits between cultivated var. frutescens and cultivated var. crispa, including effective number of branches (QN2), number of internodes (QN3), number of branches (QN4), length of the largest inflorescence (QN5), and days from germination to flowering (QN7). However, two quantitative traits-plant height and number of florets of the largest inflorescence-did not show any significant differences between cultivated var. frutescens and cultivated var. crispa. In addition, significant differences for six quantitative traits were found between the accessions of cultivated var. frutescens originating from high and middle latitude areas in China, which included QN2, QN3, QN5, number of florets of the largest inflorescence (QN6), and QN7. Principal components analysis (PCA) identified five quantitative characters [plant height (QN1), QN2, QN3, QN4, QN7] and six qualitative characters [fragrance of plant (QL1), color of reverse side of leaf (QL3), degree of pubescence (QL5), color of flower (QL6), shape of leaf (QL7), and hardness of seed (QL10)] that contributed to the positive direction on the first axis. The other quantitative and qualitative characters contributed to the negative direction on the first axis. Most accessions of cultivated var. frutescens and cultivated var. crispa were clearly separated by the first axis. In addition, most accessions of cultivated var. frutescens are from high latitude and middle latitude areas that were clearly separated by the first axis, except for several accessions. The findings from this study will provide useful information towards understanding the morphological variation of Perilla crop according to geographical distribution in high and middle latitude regions of China.
