Widespread worldwide Peucedanum plants (Apiaceae) have been used for centuries as plant medicines. The polymorphism of this genus is consistent with chemotaxonomically and therapeutically significant differences in the composition secondary metabolites. GC-MS tauricum M.B. volatiles from headspace (HS) hydrodistilled essential oil (HD), both obtained simultaneously flowers (FL), immature ripe f...

In the course of our investigation for the antibiotic-producing actinomycetes. Thirty-two actinomycete strains were isolated from Thai hot spring sediment. The generic identities of these isolates were determined by using a procedure that combined morphological, chemotaxonomic and 16S rDNA sequence-based phylogenetic analyses. Actinomycetes belonging to a total of 4 genera were identified. They...

Kocuria kristinae, previously called Micrococcus Kristinae was first described in 1974[1]. The organism is found widespread in nature, frequently as normal skin flora on humans and other mammals. It is usually non-pathogenic. There are very few documented cases with infections caused by Kocuria kristinae . Of these a majority occur in patients with indwelling devices, underlying diseases and su...

Taxonomy of prokaryotes has remained a controversial discipline due to the extreme plasticity of microorganisms, causing inconsistencies between phenotypic and genotypic classifications. The genomics era has enhanced taxonomy but also opened new debates about the best practices for incorporating genomic data into polyphasic taxonomy protocols, which are fairly biased towards the identification ...

Phytochemical reinvestigation of the roots and rhizomes of Veratrum taliense yield three known (solanidine, veramiline-3-0-~D-glucopyranoside and stenophylline B-3-0-~D-glucopyranoside) and two novel steroidal alkaloids. The structures of the new compounds have been established by a combination of spectroscopic methods as 3angeloylzygadenine-I3-N-oxide and (20S,25S)-22,26-epiminocholesta-5,22-d...

tural elucidation of eighteen new and sixteen known acyl glucoses having caffeoyl, coumaroyl and hexahydroxydiphenoyl groups from Balanophora japonica M. (Balanophoraceae) collected in Nagasaki Perfecture, Japan which was used as an antipyretic, an antitode and a hemostatic medicine in China. In a continuation of our studies on the chemical constituents of medicinal parasitic plants, we further...

The aerial parts of Artemisia iwayomogi afforded, in addition to already known terpenes, eleven new eudesmanolides whereas four new guaianolides were found in A. gmelinii. No sesquiterpene lactones were detected in the aerial parts of A. santolinifolia which afforded two new nerolidol derivatives besides several other already known compounds. From A. caerulescens var. cretacea six eudesmanolide...
