  摘要：

  通过柱色谱分离 Amomum xanthioides 种子的 MeOH 提取物，得到了一种新的二萜糖苷 amoxanthoside A (1)，两种新的单萜糖苷 (1S,4S,5S)-5-exo-hydroxycamphor 5-O-β-D-glucopyranoside (2) 和 (1R,4R,5S)-5-endo-hydroxycamphor 5-O-β-D-glucopyranoside (3)、4R,5S)-5-endo-hydroxycamphor 5-O-β-D-glucopyranoside (3)，以及四种已知化合物：hedychiol A (4)、pygmol (5)、(1S,4R,6R)-(+)-6-endo-hydroxycamphor (6) 和 dihydroyashabushiketol (7)。新化合物的结构是通过光谱分析（包括大量二维核磁共振数据）确定的。利用磺胺 B 生物测定法测试了分离出的化合物对四种人类癌细胞系的体外细胞毒性。

  Column chromatographic isolation of the MeOH extract of the seeds of Amomum xanthioides afforded a new diterpene glycoside, amoxanthoside A (1), two new monoterpene glycosides, (1S,4S,5S)-5-exo-hydroxycamphor 5-O-β-D-glucopyranoside (2) and (1R,4R,5S)-5-endo-hydroxycamphor 5-O-β-D-glucopyranoside (3), together with four known compounds, hedychiol A (4), pygmol (5), (1S,4R,6R)-(+)-6-endo-hydroxycamphor (6), and dihydroyashabushiketol (7). The structures of the new compounds were determined through spectral analysis, including extensive 2D NMR data. The isolated compounds were tested for their cytotoxicity against four human cancer cell lines in vitro using a sulforhodamine B bioassay.
