Antifungal active triterpene glycosides from sea cucumber Holothuria scabra.
To study the new antifungal active triterpene glycosides of sea cucumber Holothuria scabra. Triterpene glycosides from Holothuria scabra were separated and purified by silica gel chromatography, reversed-phase silica gel chromatography and RP-HPLC. Their structures were elucidated on the basis of spectral data and chemical evidence. Three triterpene glycosides were identified as scabraside A (1...
متن کاملTwo new cytotoxic triterpene glycosides from the sea cucumber Holothuria scabra.
Two new triterpene glycosides, scabraside A (1) and B (2), and a structurally known compound (3), were isolated from the sea cucumber Holothuria scabra (Holothuriidae) collected from the South China Sea. Structure of these compounds was elucidated by spectroscopic and chemical methods. The glycosides 1 and 2 exhibit the same common structural features, i. e., the presence of 12- and 17-hydroxy ...
متن کاملIsolation and characterization of bacteria from the lesion of juvenile sea cucumber Holothuria scabra (Jaeger, 1938) with symptom of skin ulceration disease
Echinoderm diseases have attracted little interest in contrast to the other commercial marine organisms. This study reports the pathogenesis pattern of juvenile Holothuria scabra. 11 pure bacteria were isolated from lesions of juvenile H. scabra with the symptoms of skin ulceration disease. Phylogenetic identification based on 16S rRNA gene sequences analysis revealed that they belonged to the ...
متن کاملSettlement preferences and early migration of the tropical sea cucumber Holothuria scabra.
Settlement and post-settlement processes of the sea cucumber Holothuria scabra Jaeger were studied in the laboratory. Independent and paired choice experiments revealed that several substrates could induce metamorphosis into pentactulae, but that specific substrates favoured settlement. Leaves of seagrass Thalassia hemprichii, with or without their natural bio-film, yielded the highest settleme...
متن کاملIsolation and characterization of polymorphic microsatellite loci in the sea cucumber Holothuria scabra.
The sea cucumber Holothuria scabra is an endangered species. In this study, nine new polymorphic microsatellite loci were developed and tested in 30 individuals. The number of alleles ranged from 2 to 5, and the observed and expected heterozygosities ranged from 0.1200 to 0.7391 and from 0.2408 to 0.5983, respectively. No loci significantly deviated from the Hardy-Weinberg equilibrium af-ter a ...
