The morphological characters of the spicules and other skeletal structures of each species are illustrated in de-tials with Scanning Electron Micrographs and compared with each other.展开更多

Seven new aromatic polyketides, communols A-G (1-7), were isolated and identified from the fermentation broth of Penicillium commune 518, a marine-derived fungus associated with the Gorgonian, Muricella abnormalis. ...Seven new aromatic polyketides, communols A-G (1-7), were isolated and identified from the fermentation broth of Penicillium commune 518, a marine-derived fungus associated with the Gorgonian, Muricella abnormalis. The new structures of 1-7 were determined by spectroscopic analysis and X-ray single crystal diffraction. Among them, communol D (4) was the first example of a naturally occurring aromatic polyketide with a sulfoxide group from marine thngi. Compounds 1, 6, and 7 all showed moderate antimicrobial activities against Escherichia coli and Enterobacter aerogenes with MIC values of 4.1/16.4, 6.4/25.8, and 23.8/23.8μmoloL^-1, respectively.展开更多

Anthogorgiene P (1) contains an unprecedented cubebane nucleus which is rarely found from nature. The structures of new compounds were elucidated on the basis of extensive spectroscopic methods (IR, UV, MS, CD and NMR). Compound 7 showed potent antifouling activity against the larval settlement of Balanus amphitrite, while 1 and 4 possessed moderate inhibition.展开更多
文摘Biostatistics (F analysis and Duncan's new multiple range test) combining with numerical and traditional taxonomy is used to report one new species, ( Isis minorbrachyblasta(I. m) ) as well as I. hippuris (I. h) and I. reticulata(I. r) from the China seas. The morphological characters of the spicules and other skeletal structures of each species are illustrated in de-tials with Scanning Electron Micrographs and compared with each other.
