面包海星中一个新的化合物面包海星皂苷G
Novaeguineside G ,A New Aasterosaponine from the Starfish Culcita novaeguineae
摘要
Abstract
Objective:To study the bioactive asterosaponin from the starfish Culcita novaeguineae. Methods:Guided by Pyricularia oryzae bioassay method with a combination of multi-chromatographies, the bioactive asterosaponins were separated from the srarfish Culcita novaeguineae. Results:A asterosaponin was obtained and identified by chemical methods and spectral analyses especially ESI-MS and 2D-NMR techniques,its structure was elucidated as:sodium (20R,22R,23S,24S)-6α-o-{β-D- fucopyranosyl-(1→2)-β-d-quino-vopyranosyl-(1→4)-[β-D-quinovopyranosyl-(1→2)] -β-D-quinovopyranosyl-( 1→3 )-β-D-glucopyranosyl } -22,23-epoxy-20-hydroxy-24-methyl-5α-cholest-9( 11)-en-3β-yl-sulfate. Conclusion:The compound is a new asterosaponin,named as novaeguineside G.关键词
