Microbial transformation of ginsenoside Rb1 to compound K by Lactobacillus paralimentarius. In this study, the major ginsenoside Rb1 was transformed into the more pharmacologically active minor compound K by food grade Lactobacillus paralimentarius LH4, which was isolated from kimchi, a traditional Korean fermented food.
The cell-free enzyme hydrolyzed the two glucose moieties attached to the C-3 position and the outer glucose moiety attached to the C position of the ginsenoside Rb1. The cell-free enzyme hydrolyzed the ginsenoside Rb1 along the following pathway: Our results indicate that Lactobacillus paralimentarius LH4 has the potential to be applied for the preparation of compound K in the food industry.
Biotransformation of major ginsenosides into compound K by a new Biotransformation of major ginsenosides into compound K by a new Penicillium dipodomyicola African Journal of Biotechnology The transformation products were identified by thin Directory of Open Access Journals Sweden.
Full Text Available Minor ginsenosidessuch as compound K, Rg3 S, which can be produced by deglycosylation of ginsenosides Rb1, showed strong anti-cancer effects.
However, the aprendkces effects of gypenoside LXXV, which is one of the deglycosylated shapes of ginsenoside Rb1, is still unknown due to the rarity of its content in plants. Taken together, this enzymatic method would be useful in the preparation of gypenoside LXXV for the functional food and pharmaceutical industries. Moreover, ginseng flowers, with 5. Transformation mechanisms of ginsenosides in ginseng flowers upon baking and steaming were thus explored.
Results show that baking and steaming caused a 3. Among the 20 ginsenosides with standards, polar ginsenosides were abundant in ginseng flowers baked or steamed at lower temperatures, whereas less polar ginsenosides occurred and were enriched at higher temperatures. Moreover, both the two heating methods triggered aprenduces acetylation and thus caused formation of 16 acetylginsenosides.
Finally, a new transformation mechanism concerning acetyl- ginsenosides formation was proposed. Heating is a traditional method used in ginseng root processing, however, there aren’t reports on differences resulting from aprfndices and steaming.

Sex identification of vultures is of key importance for the purpose of conservation breeding as it is desirable to have an equal sex ratio in these monogamous species which lvey housed together in large colony aviaries. Because vultures are monomorphic, with no differences in external morphology or plumage colour levg the sexes, other norverto are required for sex identification. Molecular methods for sex identification in birds rely on allelic length or nucleotide ammor discrimination of the chromohelicase-DNA binding CHD gene located on male and female chromosomes ZZ and ZW, respectively.
We characterized the partial sequences of CHD alleles from Gyps indicus, Gyps bengalensis, Gyps himalayensis and Aegypius monachus and analysed the applicability of five molecular methods of sex identification of 46 individual vultures including 26 known-sex G.
The method is also suitable to augment ecological studies for identifying sex of these endangered birds during necropsy examinations especially when gonads are not apparent, possibly due to regression during non-breeding seasons. The treatment implementation advisor: The treatment implementation advisor is one of the knowledge based advisory modules of Gyps ES, a knowledge system llevy for decision support in gypsy moth management. Its function is to provide detailed advice on intervention tactics for gypsy moth: White-backed Vulture Gyps africanus parental care and chick growth Persistent vulture declines across Africa are a cause for concern as the number of species threatened with extinction increases.
The White-backed Vulture Gyps aprnedices was, until recently, considered abundant but has been declining rapidly in recent years due to various threats including decreasing food availability. Because vultures are monomorphic, with no differences in external morphology or plumage colour between the sexes, o Possibly the widespread usage of Diclofenac drug in the animal led to the rapid population decline for these Vultures Green et al.

In Malabar hills region of India the breeding season of Long-billed Vultures was noted to be November to May where it breed mainly on cliffs Edward, Biotransformation of ginsenosides F4 and Rg6 in zebrafish. Ginsenosides F 4 and Rg 6 GF 4 and GRg 6two main active components of steamed notoginseng or red ginseng, are dehydrated disaccharide saponins.
In this work, biotransformation of ginsenosides F 4 and Rg 6 in zebrafish was investigated by qualitatively identifying their metabolites and then proposing their possible metabolic pathways.
The prediction of possible metabolism of ginsenosides F 4 and Rg 6 using zebrafish model which can effectively simulate existing mammals model was early and quickly performed.
A total of 8 and 6 metabolites of ginsenosides F 4 and Rg 6 were identified in zebrafish, respectively. It was concluded that loss of rhamnose aprenidces position C-6 and glucuronidation at position C-3 in zebrafish were considered as the main physiologic and metabolic processes of ginsenosides F 4 and ginsenosides Rg 6respectively. Based on extensive calculations of the excitation rates of Fe XVIIfour temperature-sensitive line ratios are investigated, paying special attention to the contribution of resonances to the excitation rates and to the contributions of dielectronic recombination satellites to the observed line intensities.
Temperature-sensitive line ratios are also computed for emitting gas covering a broad temperature range. It is found that each ratio yields a differently weighted average for the temperature and that this accounts for some apparent discrepancies between the theoretical ratios and solar observations.

Full Text Available Four known ginsenosides: The isolated and synthetic compounds were tested in an anti-tumor bioassay, and compounds showed considerable cytotoxicity SRB against several human cancer cell lines breast cancer MCF-7, skin melanoma SK-MEL-2 and human ovarian carcinoma B16, but moderate effects on lung carcinoma COR-L The other ginsenosides showed no effects.
Full Text Available As the main bioactive constituents of Panax species, ginsenosides possess a wide range of notable medicinal effects such as anti-cancer, anti-oxidative, antiaging, anti-inflammatory, anti-apoptotic and neuroprotective activities. However, the increasing medical demand for ginsenosides cannot be met due to the limited norbertto of Panax species and the low contents of ginsenosides.
In recent years, biotechnological approaches have been utilized to increase the production of ginsenosides by regulating the key enzymes of ginsenoside biosynthesis, while synthetic biology strategies have been adopted to produce ginsenosides by introducing these genes into yeast. This review summarizes the latest research progress on cloning and functional characterization of key genes dedicated to the production of ginsenosideswhich not only lays the foundation for their application in plant engineering, but also provides the building blocks for the production of ginsenosides by synthetic biology.
Bioavailability of ginsenosides from white and red ginsengs in the simulated digestion model.
This study aims to investigate the bioavailability of ginsenosides during simulated digestion of white WG and red RG ginseng powders. Stability, bioaccessibility, and permeability of ginsenosides present in WG and RG were studied in a Caco-2 cell dek model coupled with oral, gastric, and small intestinal simulated digestion. However, the bioaccessibility of protopanaxatriol type ginsenosides in the early food phase was greater than that of the protopanaxadiol type.
The less polar RG ginsenosides were released later following the jejunum phase. Ginsenosides had low permeability digestion and that ginsenosides are poorly absorbed in humans. Diclofenac disposition in Indian cow and levvy with reference to Gyps vulture population declines.
Vultures scavenge livestock carcasses that have been treated with diclofenac within the days preceding death. We present data on diclofenac disposition in Indian cow and goat, and field data on the prevalence of diclofenac in carcases in the environment. In cow, diclofenac was detectable in liver, kidney and intestine up to 71 h post-treatment; in plasma, half-life was In goat, tissue residues were undetectable after 26 h.
Prevalence of diclofenac in liver from 36 dead livestock collected in the field was Data suggest that diclofenac residues in Indian cow and goat are short-lived, but diclofenac prevalence in carcasses available to vultures may still be very high.
