Diterpene glycosides from Senecio rufus

Phytochemistry, 1992
Abstract Two new diterpene glycosides, named rufusoside A and B were isolated from Senecio rufus. Their structures have been established as ent-15α-(α- l -arabinopyranosyloxyl)- kaur-16-en-19-oic acid and ent-15α-(ζ- l -arabinopyranosyloxyl)-kaur-16-en-19- oic acid-β- d -glucopyranosyl ester, respectively, mainly through interpretation of their ...

Three diterpene dilactone glycosides from Podocarpus nagi

Phytochemistry, 1995
Three water-soluble constituents, nagilactosides C-E, were isolated from Podocarpus nagi. Their structures were determined by chemical and spectroscopic methods, respectively. Nagilactoside C was identified as 1-deoxy-nagilactone A-2 alpha-O-beta-D-glucopyranosyl-(1-->3)-beta-D-glucopyranoside, nagilactoside D as 1-deoxy-nagilactone A-2 alpha-O-beta-D ...

New Labdane Diterpene Glycosides from Amphiachyris amoena

Journal of Natural Products, 1995
Five new labdane diterpene glycosides, amoenolide A 19-beta-D-glucopyranoside [1], and amoenolides E [3], F [4], G [6], and H [8] were isolated from the above-ground parts of Amphiachyris amoena. Amoenolide F is a 19-beta-D-glucopyranoside, while the others are 6-alpha-L-arabinopyranosides.

Diterpene glycosides from Stevia phlebophylla A. Gray

Carbohydrate Research, 2013
The rare Mexican species Stevia phlebophylla A. Gray was long considered to be the only known Stevia species, beside the well-known S. rebaudiana, containing the highly sweet diterpenoid steviol glycosides. We report a re-evaluation of this claim after phytochemically screening leaves obtained from two herbarium specimens of S.

Rebaudioside F, a diterpene glycoside from Stevia rebaudiana

Phytochemistry, 2002
The sweet diterpenoid glycoside, rebaudioside F, was isolated from leaves of a high rebaudioside C producing line of Stevia rebaudiana, and its structure was established by chemical and spectral studies.

Sesquiterpene and diterpene glycosides from Xanthium spinosum

Phytochemistry, 1996
Abstract Two new sesquiterpene lactone glycosides and three new kaurene glycosides closely related to carboxyatractyloside and atractyloside, together with the 3′, 4′-didesulphated-carboxyatractyloside and 3′, 4′-didesulphated-atractyloside, were isolated from the aerial parts of Xanthium spinosum . Their structures were established by spectroscopic

Isolation and characterization of diterpene glycosides from Siegesbeckia pubescens

Bioorganic & Medicinal Chemistry Letters, 2017
Five new diterpenoid glycosides, siegesides A-E (1-5), along with the known compound darutoside (6) were isolated and characterized from the ethanol extract of Siegesbeckia pubescens. The structural elucidation of the isolates was accomplished by extensive HRESIMS and NMR analysis. Compounds 1 and 2 are epimers of 6.
