The essential oil from the leaves of Murraya alata Drake was extracted by hydrodistillation and analyzed by GC-MS. A total of 70 components were identified, accounting for 93.7% of the oil composition. The major compound is -cadinol (18.9%), followed by -muurolol (10.0%), trans-prenyl limonene (7.7%), germacra-4(15),5,10(14)-trien-1--ol (6.0%), and cedryl acetate (5.4%). M. alata oil was cha...
An aerobic actinomycete, designated SCSIO 01299(T), was isolated from a deep-sea sediment collected from the northern South China Sea at a depth of 3258 m. The isolate was found to be a natural producer of the synthesized antitumour agent deoxynyboquinone and its three new derivatives, pseudonocardians A, B and C. A blast search based on almost-complete 16S rRNA gene sequences showed that strai...
Lichens are symbiotic organisms of fungi and algae or cyanobacteria. Lichen-forming fungi synthesize a great variety of secondary metabolites, many of which are unique. Developments in analytical techniques and experimental methods have resulted in the identification of about 1050 lichen substances (including those found in cultures). In addition to their role in lichen chemotaxonomy and system...
The Bocconieae tribe, consisting of only the genera Macleaya and Bocconia, possesses significant economic and medicinal value and plays an important role in health management for people in developing countries. During the past decades, research on metabolites and relative pharmacology, including the isolation and identification of a variety of molecules, has shed light on the tribe. Among those...
A bacterium capable of degrading microcystins-RR, -YR, and -LR was isolated from a hypertrophic lake. The bacterium, designated Y2 and classified phenotypically as a member of the genus Sphingomonas, was shown to be distinct phylogenetically from any established species of Sphingomonas on the basis of 16S rDNA sequencing. The bacterium was tentatively identified as Sphingomonas by manual chemot...
