Two iridoid glucosides, namely boschnaloside (2), (+)-pinoresinol-β-D-glucopyranoside (3), a new oligosaccharide (=β-D-glucopyranosyl(1->4)-α-L-rhamnopyranosyl-(1->3)-D-(4-O-caffeoyl)-glucopyranose) (4), and a new phenylpropanoid glycoside named rossicaside A (5) have been isolated from Boschniakia rossica FEDTSCH, et FLEROV (Orobanchaceae) and their structures have been determined.Keywords--Boschniakia rossica; Orobanchaceae; boschnaloside; boschnaside; (+)-pinoresinol-β-D-glucoside; acetylated oligosaccharide; rossicaside A; phenylpropanoid 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.
