Soil moisture conditions are critical for seed emergence in soils. As soils of Saemangeum reclaimed land coarse-textured, the soil may not be suitable upland cultivation due to low water holding capacity. This study was performed investigate rates sesame (Sesamum indicum L.), perilla (Perilla frutescens peanut (Arachis hypogaea and sorghum (Sorghum bicolor L.) under land. Three experiment condu...
In the present study, the effects of perilla leaf extract (PLE) and luteolin on 7,12-dimethylbenz[a]anthracene (DMBA)- and 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced skin papillomas in mice were investigated. Topical application of PLE prior to TPA treatment in DMBA-initiated mouse skin resulted in a significant reduction in tumor incidence and multiplicity. An even more potent preventi...
The leaves of Perilla frutescens (L.) Britt. have been traditionally used as an herbal medicine in East Asian countries to treat a variety diseases. In this present study, we investigated the inhibitory effects of P. frutescens extract (PFE) on N-formyl-Met-Leu-Phe (fMLF)-stimulated human neutrophils and the underlying mechanisms. PFE (1, 3, and 10 μg/ml) inhibited superoxide anion production, ...
Activity-directed fractionation and purification processes were employed to identify xanthine oxidase (XO) inhibitory compounds from the leaves of Perilla frutescens. The total extract was evaluated in vitro on XO inhibitory activity and in vivo in an experimental model with potassium oxonate-induced hyperuricemia in mice which was used to evaluate anti-hyperuricemic activity. The crude extract...
A molecular biological approach was applied to the study of diversity and regulation of secondary metabolism in medicinal plants at various levels. For the inter-species diversity, RFLP (restriction fragment length polymorphism) and RAPD (random amplified polymorphic DNA) analyses of genomic DNA were performed on the plants, belonging to the same genus or family and containing related compounds...
