Polyketides with Cardioprotective Bioactivities from Sponge-Associated Fungus MA46-5.

One pair of novel enantiomers, gigantdioxin A (+)- and B (-)-, with a skeleton of benzo[][1,3]dioxin; a new acetophenone gigantone A (); a known 3-chlorogentisyl alcohol (), which is the bioprecursor of ; acetophenone (); and chromone derivative () were obtained from the sponge-associated fungus MA46-5. Their structures were established by extensive and in-depth spectral analysis, such as UV, 1D and 2D NMR, and HRESIMS. The absolute configurations of (±)- were deduced by ORD, chiral separation, and experimental and computational ECD.

 (Poaceae, Bambusoideae), a new combination supported by morphological and molecular evidence.

Morphological characteristics and phylogenetic analyses clearly revealed that should be a member of the genus , rather than , and is a distinct species close to and . Morphologically, it differs from all the other known species by internodes initially with white pubescent, culm leaf auricles absent and triangularly subulate sheath blades, characteristics that are unusual in this genus. And this morphological distinction warrants recognition of as a new combination of .

Genome survey and development of 13 SSR markers in by NGS.

is a valuable timber tree species for its high durability and excellent sawmilling qualities. However, there is lack of complete genomic information for this plant, which severely constrains its genetic improvement. This study aim to survey the genome of .

Anti-depressive activities and biotransformation of timosaponin B-III and its derivatives.

Timosaponin B-III (TB-III) is a steroidal saponin isolated from the rhizome of Anemarrhenae asphodeloides (Liliaceae). The biotransformation of TB-III by β-glucosidase was investigated. Three biotransformation products were isolated and their structures were identified as timosaponin B-III-a (M1), (20R,25S)-5β-spirostane-3β-ol-3-O-β-D-glucopyranosyl-(1 → 2)-β-D-galacopyanoside (M2) and timosaponin AIII (M3).

Development of polymorphic microsatellite markers for Phyllostachys edulis (Poaceae), an important bamboo species in China.

Premise Of The Study: Polymorphic microsatellite markers were developed for Phyllostachys edulis (Poaceae), an ecologically and economically important bamboo species in China, to evaluate the genetic diversity and population genetic structure of P. edulis and other Phyllostachys species. •

Methods And Results: Twenty microsatellite markers were developed and their polymorphisms were tested on 71 samples from three geographically disparate populations.

[Hepatoprotective effects of Gentiana scabra on the acute liver injuries in mice].

Objective: To study the hepatoprotective effect of the aerial parts and the roots of G. scabra on cute liver injury models.

Method: Acute liver injury models were induced by CCl4, TAA and D-GlanN in mice, and the levels of serum enzyme ALT, AST and AKP on acute liver injury mice with extracts of theaerial parts and the roots of G.
