Isolation of glycosidase-inhibiting hyacinthacines and related alkaloids from Scilla socialis.
An examination of the bulbs of Scilla socialis has resulted in the isolation of 11 hyacinthacines, two pyrrolidines, and three piperidines. The structures of the new alkaloids were elucidated by spectroscopic methods as beta-1-C-ethyldeoxymannojirimycin (5), hyacinthacines B7 (10), C2 (11), C3 (12), C4 (13), and C5 (14), and alpha-5-C-(3-hydroxybutyl)hyacinthacine A2 (15). Although, beta-l-homofuconojirimycin (3) and alpha-7-deoxyhomonojirimycin (alpha-7-deoxy-HNJ, 4) are previously known alk...Expand abstract
