(family Fabaceae) — medicoside J, and its structure has been established as a medicagenic acid 3-O--D-glucopyranoside 28-O-[O--D-xylopyranosyl-(1 4)-O--L-rhamnopyranosyl-(1 2)--L-arabinopyranoside].Institute of the Chemistry of Plant Substances of the Uzbek Academy of Sciences.

The structure of a new cycloartane glycoside, cycloaraloside B, isolated from the roots ofAstragalus amarus Pall. (Leguminosae) has been established on the basis of chemical transformations and spectral characteristics: it is 20R,24S-epoxycycloartane-3,6,16,25-tetraol 3-O-[O--L-rhamnopyranosyl-(12)-(6-O-acetyl--D-glucopyranoside)].Institute of Chemistry of Plant Substances, Uzbekistan Academy of Sciences, Tashkent.

Conclusions Two additional cardiac glycosides, glucoerysimoside and glucoerysimosol, have been isolated from the seeds ofCheiranthus allioni Hort. Glucoerysimoside is strophanthidin 3-[O--D-digitoxopyranosyl-(4 1)-O--D-glucopyranosyl-(4 1)--D-glucopyranoside]. Glucoerysimosol is a new cardenolide having the same carbohydrate component, but its aglycone is strophanthidol. From these glycosides a new trisaccharide has been obtained which has been characterized as 4-O--cellobiosyl-D-digitoxose.Khar'kov Scientific-Research Institute of Pharmaceutical Chemistry.

The epigeal part of the plant ofAstragalus tragacantha Habl. (Leguminosae) has yielded, together with cyclosieversigenin 3-O--D-xylopyranoside, a new glycoside of the cycloartane series — cyclocanthoside D, the structure of which has been established on the basis of chemical transformations and spectral characteristics as 24S-cycloartane-3,6,16,24,25-pentaol 16-O--D-glucopyranoside 3-O--D-xylopyranoside.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSR, Tashkent.

Summary The structures of the triterpene glycosides leontiside A and leontoside B fromLeontice eversmannii have been established. It has been shown that the leontoside A is hederagenin 3--L-arabopyranoside and leontoside B is hederagenin 3--L-arabopyranosido-4--D-glucopyranoside.Khimiya Prirodnykh Soedinenii, Vol. 3, No. 2, pp. 101–105, 1967 相似文献

A new steroid glycoside of the spirostan series, anzuroside, has been isolated from the collective fruits of the cocultivatedAllium suvorovii Rgl. andA. stipitatum Rgl. (family Liliaceae, local name anzur). Enzymatic cleavage of the glycoside has given the previously undescribed steroid sapogenin anzurogenic C, which has the structure of (24S, 25S)-2,3,5,24-tetrahydroxy-5-spirostan-6-one. Anzuroside is the 24-O--D-glucopyranoside of anzurogenin C.Institute of the Chemistry of Plant Substances, Uzbek SSR Academy of Sciences, Tashkent.

Two new triterpene glycosides — cucmariosides C1 and C2 — have been isolated from the Far Eastern holothurianEupentacta (=Cucumaria)fraudatrix Djakonov et Baranova. Their structures have been established with the aid of13C NMR and PMR spectroscopy, partial acid hydrolysis, periodate oxidation, and methylation as 16-acetoxy-3-{[3-O-methyl--D-xylopyranosyl-(13)--D-glucopyranosyl-(14)] [-D-xylopyranosyl-(12)]--D-quinovopyranosyl-(12)--D-xylopyranosyloxy}holosta-7,23,24(cis)-triene and 16-acetoxy-3-{[3-O-methyl--D-xylopyranosyl-(13)--D-glucopyranosyl-(14)] [-D-xylopyranosyl-(12)]--D-quinovopyranosyl-(12)--D-xylopyranosyloxy}holosta-7,22,24(trans)-triene, respectively.Pacific Ocean Institute of Bioorganic Chemistry of the Far-Eastern Scientific Center of the USSR Academy of Sciences, Vladivostok.

The structure of psolusoside B — a minor triterpene oligoglycoside from the holothurianPsolus fabricii and the main glycoside fromPsolus sp. has been determined by the methods of partial acid hydrolysis, methylation,13C NMR, and FAB mass spectrometry as 20S-acetoxy-3-{2-O-[O--D-glucopyranosyl-(1 4)-O--D-glucopyranosyl]-4-O-(6-O-sulfato--D-glucopyranosyl)--D-xylo-pyranosyloxy}holosta-7,25-diene-18,16-carbolactone. 3-[O-(3-O-Methyl-6-O-sulfato--D-glucopyranosyl)-(1 3)-O-(6-O-sulfato--D-glucopyranosyl)-(1 4)-O--D-quinovopyranosyl-(12)--D-xylopyranosyloxy]holosta-9(11),25-dien-16-one (psolusoside A), known previously forPsolus fabricii, has been identified in a holothurian —Psolus sp. — from Kraternaya Bay (island of Ushishir).Pacific Ocean Institute of Bioorganic Chemistry, Far Eastern Branch, Academy of Sciences of the USSR, Vladivostok.
