[摘要]:Etlinglittarolin (6), a monoterpene-substituted hydroperoxy-dihydrochalcone, together with five known dihydrochacones including 2', 6'-dihydroxy-4'-methoxydihydrochalcone (1), 2',4',6'-trihydroxydihydrochalcone (2), 2',6',4-trihydroxy-4'-methoxydihydrochalcone (3), methyllinderatin (4), and adunctin E (5), was isolated from the rhizomes of Etlingera littoralis. Their structures were elucidated by spectroscopic analysis. |
