This study investigated the quality of muffin prepared with various concentrations of freeze dried-perilla leaves (Perilla frutescens var. japonica HARA) powder. Muffin was prepared by addition of 0, 3, 6 and 9% powder to the flour of basic formulation. The weight of muffin decreased with increase in freeze dried-perilla leaves powder concentration, but no constant tendency in the bottom and upper dimensions by its addition was found. The height and baking loss rate of the muffin increased with increase in the powder concentration but with no significant differences. Lightness and yellowness of muffin decreased as the concentration of the powder increased, whereas no significant differences in the redness was found with increased powder concentration. The hardness of muffin increased, and springiness decreased with increase in the powder concentration, although not significant. The cohesiveness, gumminess and chewiness showed no consistent tendency by addition of the powder. The antioxidative activity measured by 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity of muffin increased as the concentration of the powder increased. The muffin contained 0~6% freeze dried-perilla leaves powder had acceptable sensory properties, such as color, taste, and overall acceptability. Results indicated that optimal concentration of freeze dried-perilla leaves powder into the muffin formula was 3~6% (w/w).

A pot experiment was carried out to investigate the effect of boron on the growth, symptom, yield, and content of boron in Perilla(Perilla frutescens var. japonica HARA), Melon(Cucumis melo L.) and Cucumber(Cucumis sativus L.). The results obtained are as follows. Perilla. melon and cucumber uptake a lot of boron from the soil, and toxic effects of boron result in leaf tip yellowing by progressive necrosis. Yield of perilla, melon and cucumber are decreased at the $3{\sim}5mg\;kg^{-1}$, $5{\sim}10mg\;kg^{-1}$ of boron applicated in soil, respectively. Boron content in the leaf is the highest among various parts plant, and the tip and margin of the leaf contained more boron than central part of the leaf. Boron applicated was moved and accumulated to the plant and soil.

To select resistant oil seed crops against two species of root-knot nematodes, Meloidogyne incognita and M. arenaria, 10 cultivars of sesame (Sesamum indicum L.) and 10 cultivars of perilla (Perilla frutescens var. japonica) were screened in greenhouse pot test. All sesame cultivars tested were resistant to M. incognita but susceptible to M. arenaria. While, perilla was resistant to both Meloidogyne species. Therefore, perilla cultivars could be used as rotation crop in greenhouse infested with both M. incognita and M. arenaria. But, sesame cultivars only can be used as a rotation crop in greenhouse infested with M. incognita but not for M. arenaria.

Perill(Perilla frutescens var. japonica $H_{ARA}$), “Ipdlkkae 1” was tested for the yield components in accordance with several different application levels, seeding methods and seeding dates. The results were summarized as follows: Application of fertilizer remarkably increased leaf number and leaf weight. Specially nitrogen showed the most significant effect. The best combination of NㆍPㆍK for cultivation of perilla was investigated ill three leveles of 6kg /10a, 9kg/10a, and 10kg/10a. The planting density in $10cm\times10cm/m^2$, and the seeding date on December 23 were found as the best results. However, $10cm\times7cm/m^2$ planting was better to get heavy leaf.Perill(Perilla frutescens var. japonica $H_{ARA}$), “Ipdlkkae 1” was tested for the yield components in accordance with several different application levels, seeding methods and seeding dates.

Among 14 medicinal plants selected for the study ethanol (70%) extract of Coptis japonica Makino showed the highest anti-microbial activity against Helicobacter pylori followed by Perilla frutescens var. acuta KUDO, Caesalpinia sappan L. and Schizonepeta tenuifolia Briq. However, anti-urease activity of methanol (80％) extracts was best for Forsythiae Fructus followed by Caesaipinia sappan L. and Schizonepeta tenuifolia Briq. In the second fractionation using water, ethyl acetate and butanol more than 90％ of the anti-urease activity was detected in the ethyl acetate fraction.

BACKGROUND/OBJECTIVES: The accumulation of amyloid-${\beta}$ ($A{\beta}$) in the brain is a hallmark of Alzheimer's disease (AD) and plays a key role in cognitive dysfunction. Perilla frutescens var. japonica extract (PFE) and its major compound, rosmarinic acid (RA), have shown antioxidant and anti-inflammatory activities. We investigated whether administration of PFE and RA contributes to cognitive improvement in an $A{\beta}_{25-35}$-injected mouse model. MATERIALS/METHODS: Male ICR mice were intracerebroventricularly injected with aggregated $A{\beta}_{25-35}$ to induce AD. $A{\beta}_{25-35}$-injected mice were fed PFE (50 mg/kg/day) or RA (0.25 mg/kg/day) for 14 days and examined for learning and memory ability through the T-maze, object recognition, and Morris water maze test. RESULTS: Our present study demonstrated that PFE and RA administration significantly enhanced cognition function and object discrimination, which were impaired by $A{\beta}_{25-35}$, in the T-maze and object recognition tests, respectively. In addition, oral administration of PFE and RA decreased the time to reach the platform and increased the number of crossings over the removed platform when compared with the $A{\beta}_{25-35}$-induced control group in the Morris water maze test. Furthermore, PFE and RA significantly decreased the levels of nitric oxide (NO) and malondialdehyde (MDA) in the brain, kidney, and liver. In particular, PFE markedly attenuated oxidative stress by inhibiting production of NO and MDA in the $A{\beta}_{25-35}$-injected mouse brain. CONCLUSIONS: These results suggest that PFE and its active compound RA have beneficial effects on cognitive improvement and may help prevent AD induced by $A{\beta}$.

Serve outbreaks of anthracnose were observed on perilla plants grown in greenhouses and open fields in several locations in Korea during the disease survey from 1997 to 2000. A total of 53 isolates of Colletotrichum spp. and Glomerella sp. was obtained from diseased perilla plants and identified based on their morphological and cultural characteristics. Forty isolates were identified as Colletotrichum gloeosporioides, three isolates as C. coccodes, five isolates as C. dematium, and the other five isolates as Glomerella cingulata, the teleomorph of C. gloeosporioides. All isolates of C. gloeosporioides tested by artificial inoculation were strongly virulent on perilla plants, but isolates of the other species were weakly or not virulent. Anthracnose symptoms induced on the perilla plants by artificial inoculation with the isolates of C. gloeosporioides were similar to those observed in the fields. This study revealed that C. gloeosporioides is the main causal fungus of perilla anthracnose.

The content analysis of fatty acids in Perilla cultivars and commercial oils is conducted through gas chromatography with a flame ionization detector. Results show that Perilla cultivars, such as Deulsaem and Daesil, contain high amounts of ${\alpha}-linolenic$ acid (262.22 and 261.97 mg/g, respectively). Among commercial oils, Perilla oil contains a higher amount of ${\alpha}-linolenic$ acid (515.20 mg/g). Accordingly, ${\alpha}-linolenic$ acid is a major fatty acid of Perilla cultivars and oil. Therefore, Perilla cultivars could be used as a food supplement for nutritional and pharmaceutical purposes.
