Four steroidal compounds were isolated from the fresh flowers of Yucca gloriosa and their structures were elucidated as tigogenin 3-O-β-D-xylopyranosyl-β-lycotetraoside, gitogenin 3-O-β-D-xylopyranosyl-β-lycotetraoside, gitogenin 3-O-α-rhamnopyranosyl-β-lycotetroside and proto-type of gitogenin 3-O-β-D-xylopyranosyl-β-lycotetraoside, on the basis of physical and chemical investigation.Key Word Index - Yucca gloriosa; Liliaceae; tigogenin glycoside; gitogenin glycosides; furostanol glycoside.

A glycoside, holothurin A1 has been isolated from the polar glycosidic fractions of the holothurians H. floridana and H. grisea.The complete structure of the glycoside has been established; it is: 3β-3)-O-β-D-glucopyranosyl-(1->4)-O-β-D-quinovopyranosyl-(1->2)-(4-sulfato-β-D-xylopyranosyl)oxy>holosta-9(11)-ene-12α,17α,22ξ-triol.Details of the IR and 1H and 13C NMR spectra of the compounds obtained are given.
