- THE STEROIDAL GLYCOSIDES OF THE FLOWERS OF YUCCA GLORIOSA
-
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 FUROSTANOL GLUCURONIDE FROM SOLANUM LYRATUM
-
A new furostanol glucuronide and three known glycosides, SL-0, aspidistrin and methyl proto-aspidistrin, were isolated from the fresh immature berries of Solanum lyratum.The structure of the new compound was characterized as 26-O-β-D-glucopyranosyl-(22ξ,25R)-3β,22,26-trihydroxyfurost-5-ene 3-O-α-L-rhamnopyranosyl-(1 -> 2)- 3)>-β-D-glucopyranoside. Key Word Index - Solanum lyratum; Solanaceae; furostanol glucuronide.-24β-ethyl-5α-cholesta-7,trans-22,25(27)-trien-3β-ol; spinasteryl-β-D-glucopyranoside.

- GLYCOSIDES OF MARINE INVERTEBRATES. XV. A NEW TRITERPENE GLYCOSIDE - HOLOTHURIN A1 - FROM CARIBBEAN HOLOTHURIANS OF THE FAMILY HOLOTHURIIDAE
-
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.
