Schisandra, Ginseng, Notoginseng, and Lycium barbarum are traditional Chinese medicinal plants sharing cognitive-enhancing properties. To design a functional food to improve memory, we prepared a compound Schisandra-Ginseng-Notoginseng-Lycium (CSGNL) extract and investigated its effect on scopolamine-induced learning and memory loss in mice. To optimize the dose ratios of the four herbal extrac...

Limestone areas are sedimentary rock outcrops consisting of calcium carbonate created several hundreds millions years ago by calcium-secreting marine organisms and subsequently lifted above sea level tectonic movement. support very high levels endemic species plants recognized as biodiversity with much biological information. The purpose this study is to devise a strategy for the comprehensive ...

OBJECTIVE To verify if the medicinal plants Panax ginseng C.A. Mey, Turnera diffusa Willd. ex Schult., and Heteropterys tomentosa O. Mach., which are amply used by the population as tonics and cognition enhancers, could have a protective effect on cell death by apoptosis, since this could be one of the mechanisms of action of these substances. METHODS Aged male Wistar rats (n = 24) were divid...

the purpose of this study was to examine the relationship of physical activity levels with sleep duration (sd), and self-rated health (srh) using the fifth korean national health and nutrition examination survey data from 2010 and 2011.overall, 12,188 korean people were evaluated in relation to meeting guidelines for vigorous pa (mvpa), moderate pa (mmpa), and low pa (mlpa) associated with sd a...

Satsuma dwarf virus (SDV) or Citrus mosaic sadwavirus (CiMV) were not consistently detected in RT-PCR assay with the primer sets based on gene of Japan isolates. SDV and CiMV isolates were distinctively divided into two groups based on phylogenetic analysis of PP2 gene cloned from 22 Korean isolates, and the Korean CiMV and SDV isolates shared 95.5-96.2% and 97.1-97.7% sequence identity with Ja...

Abstract Background In 2020, a categorized list of wetland preferences, major habitats, and life forms 4145 vascular plant taxa occurring in the Korean Peninsula was published by National Institute Biological Resources. We analyzed explored distribution patterns five groups according to preference, along with information on habitats plants belonging those categories. Results Out taxa, we found ...

Strawberry bacterial angular leaf spot (ALS) disease, caused by Xanthomonas fragariae has become increasingly problematic in the strawberry agro-industry. ALS causes small angular water-soaked lesions to develop on the abaxial leaf surface. Studies reported optimum temperature conditions for X. fragariae are 20°C and the pathogen suffers mortality above 32°C. However, at the nursery stage, dise...

In order to develop convenient and reproducible methods for the identification of ginseng drugs at a DNA level, randomly amplified polymorphic DNA (RAPD) and PCR-restriction fragment length polymorphism (PCR-RFLP) analyses were applied within Panax species. To authenticate Panax ginseng among ginseng populations, RAPD analysis was carried out using a 20 mer-random primer. The similarity coeffic...

BACKGROUND Korean ginseng (Panax ginseng Meyer) is a perennial herb prone to various root diseases, with Phytophthora cactorum being considered one of the most dreaded pathogens. P. cactorum causes foliar blight and root rot. Although chemical pesticides are available for disease control, attention has been shifted to viable, eco-friendly, and cost-effective biological means such as plant growt...
