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 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 ...
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 کاملApplication of dried shrimp head in the diets of sea cucumber Holothuria scabra
This study aims to determine the suitability of dried shrimp head as part of the ingredient in formulated diet to promote growth of sea cucumber in captivity. The sea cucumber Holothuria scabra were divided into two tanks to test two different diets: Diet A (commercial diet supplemented with dried shrimp waste) and Diet B (commercial diet without dried shrimp waste). A total of 20 pieces of H. ...
