Soil properties and heavy metal (HM) concentrations in the field soils where balloon flowers (Platycodon grandiflorum, BF) were cultivated, were investigated together with HM (Cd, Cu, Pb, and Zn) accumulation by the BF roots. Basically, in most soils examined (51-97% among 65 samples), the chemical properties including soil pH, organic matter, available-P, and exchangeable cation contents appeared to be lower than the optimal ranges for balloon flower cultivation. There were no samples exceeding the standard limits for HM in soils. Instead, the total HM concentration levels in soils appeared to be maintained at around background levels for general soil in Korea. This implied that elevated HM accumulation in the soils caused by any possible input sources was unlikely. Even though the BF cultivated soils were not contaminated by HM, it was appeared that substantial amount of Cd was accumulated in BF roots with 1.5% and 35% roots samples exceeding the standard limits legislated for BF root ($0.81mg\;kg^{-1}DW$) and herbal plants ($0.3mg\;kg^{-1}DW$), respectively. This implied that the soil HM standard limits based on the total concentration does not reflect well the metal accumulation by plants and also it is likely that the Cd standard limits for BF and herbal plants is too restrict.

Objective : For the purpose of developing Korean herbalogy of the plants to Aspleniaceae in Korea, the literatures of the successive generations have been thoroughly investigated to prepare this article. Methods : The examined herbalogical books and research paper which published at home and abroad. Results : 1. There are 2 genera and 21 species in Aspleniaceae in Korea and among them medicinal plants are 2 genera and 10 species, some 48% in total. 2. Asplenium genus is a main kind in that it has 20 species among 21 species in Aspleniaceae of which medicinal plants are 9 species. 3. The Herb play medicinal parts if most plants in the Aspleniaceae have the effect of a medicine, the 10 species of which are used for medical care. 4. According to nature and flavor of medicinal plants in the Aspleniaceae, the cold medicinal plants and the bitter medicinal plants take the highest number of them 5. According to the properties and principal curative action, they were classified into drugs for hemostatic 10 species, drugs for clearing away heat 8 species, drugs for detoxification 7 species respectively. 6. None of the species of Aspleniaceae have been found to be toxic. Conclusions : There are totaled to 2 genera and 21 species in Aspleniaceae in Korea and among them medicinal plants are 2 genera and 10 species some 48% in total.

Medicinal plants are high-value natural resources that have been used as precautionary drugs by many people globally. The increasing global demand for bioactive compounds from medicinal plants has led to the overexploitation of many valuable species. One widely used approach to overcome this problem is the use of adventitious root cultures as a propagation strategy. This review examines the scientific research published globally on the application of adventitious root cultures for many medicinal plants. Adventitious roots generated under aseptic environments in suitable phytohormone-augmented medium exhibit high growth rates and production of important secondary metabolites. Parameters such as medium properties and composition, growth hormone type, and elicitation strategies for in vitro grown adventitious roots of medicinal plants, are the main topics discussed in this review. We also examine current developments in bioreactor system cultivation for plant bioactive compounds using adventitious root cultures, a technology with possible commercial applications, via several studies on adventitious root culture of medicinal plants in which bioreactor systems play a role. In conclusion, the development of adventitious root cultures for medicinal plants is highly useful because of their capability for vegetative propagation and germplasm preservation.

An extracellular polymer (exo-polymer) with hepatoprotective properties was produced after a 6-day submerged mycelial culture of Ganoderma lucidum WK-003. The glutamic pyruvic transaminase (GPT) activities in the serum of intoxicated Sprague-Dawley rats were decreased from 871 to 263 by the oral administration of the exo-polymer (20 mg/kg/day) for 4 consecutive days. Rhamnose, arabinose, xylose, mannose, galactose, and glucose were found in the exo-polymer along with aspartic acid, glutamic acid, histidine, serine, glycine, arginine, alanine, tryptophan, valine, phenylalanine, isoleucine, and leucine.

Garlic (Alium sativum L.), originated in the Kirghiz region of Central Asia, is oneof the oldest cultivated plants. It has reached Europe via Egypt in the days of Pharaohs. Since then, the legendary medicinal properties attributed to garlic have attracted human interests for thousands of years. However, the research on the medicinal effect of garlic, mostly on this anticarcinogenic actions has been systematically performed only for the last tow or three decades. Many researches have proven that garlic inhibits neoplasia elicited by chemical carcinogens using in vitro or in vivo experimental systems. Attention has recently been focused on assessing the therapeutic or chemopreventive measures of garlic compounds against carcinogenesis in animals. The active principles of he garlic extract, mainly the sulfur compounds and their derivatives have been deeply scrutinized into their chemical, functional and medicinal properties.

Compared to their terrestrial and marine counterparts, little is known about the capacity of freshwater-derived actinomycete bacteria to produce novel secondary metabolites. In the current study, we highlight the disparities that exist between cultivation-independent and -dependent analyses of actinomycete communities from four locations in Lake Michigan sediment. Furthermore, through phylogenetic analysis of strains isolated from these locations, we identified a Streptomyces sp., strain B025, as being distinct from other Streptomyces spp. isolated from sediment. Upon fermentation this strain produced a rare class of eight-membered lactone secondary metabolites, which have been for their antitumor properties. We used spectroscopic and chemical derivitization techniques to characterize octalactin B (1) in addition to its corresponding novel, unnatural degradation product (2).
