glycosides, eulophiosides A and B (3, 4), were isolated from Eulophia andamanensis in addition to six known compounds. The known compounds were identified as gastrodin (1), vitexnegheteroin A (2), grammatophylloside A (5), grammatophylloside B (6), pleionoside E (7), and pleionoside F (8). Their structures were determined based on the physical data and the spectroscopic evidence including 1D and 2D NMR experiments
