Abstract: Abstract Two non-sulfated steroidal glycosides, cistoindosides A-B were isolated from organic extract of the marine ‘old woman octopus’ Cistopus indicus (family Octopodidae). Their structures were characterized as 3β-acteoxy-23β-hydroxy-cholesta-9-ene-β-D-xylopyranoside (cistoindoside A) and 22,23-epoxy-3β-hydroxy-cholesta-5-ene-β-D-4'-O-acetoxy-xylopyranoside (cistoindoside B). Cistoindoside… read more here.
