Abstract Scilliphaeoside (I), C 30 H 42 O 9 , and glucoscilliphaeoside (III), C 36 H 52 O 14 , represent two minor glycosides which occur in the bulbs of the white sea onion or squill [ Scilla (= Urginea ) maritima (Baker) L.]. Glucoscilliphaeoside is easily converted into scilliphaeoside and D‐gluc...
