New pregnane glycosides from Cynanchum ascyrifolium.
Two new pregnane glycosides, cynascyrosides D and E, were isolated from the roots of Cynanchum ascyrifolium. The structures of these compounds were determined on the basis of spectroscopic and chemical evidence as cynajapogenin A 3-O-alpha-L-cymaropyranosyl-(1-->4)-beta-D-digitoxopyranosyl-(1-->4)-beta-L-cymaropyranoside and cynajapogenin A 3-O-beta-D-glucopyranosyl-(1-->4)-alpha-L-diginopyrano...
متن کاملNew pregnane glycosides from Gymnema sylvestre.
Four new pregnane glycosides 1-4 were isolated from the ethanol extract of the stem of Gymnema sylvestre and named gymsylvestrosides A-D. Hydrolysis of compound 1 under the catalysis of Aspergilus niger β-glucosidase afforded compound 5 (gymsylvestroside E). Their structures were determined by spectroscopic methods such as HRESIMS, 1D and 2D NMR, as well as HMQC-TOCSY experiment. Compounds 1-4 ...
متن کاملPregnanes and pregnane glycosides from Hoya carnosa.
Eleven pregnanes were isolated from the hydrolysate of the CHCl3 extract fractionated from the caules of Hoya carnosa. Among these, six pregnanes, including 19-acetoxydigipurpurogenin II, were new, and their structures were elucidated. The structures of twenty new pregnane tetraosides and pentaosides, named hoyacarnosides A-T, besides three known ones from the CHCl3 extract, were determined.
متن کاملAcylated pregnane glycosides from Caralluma tuberculata and their antiparasitic activity.
Five pregnane glycosides were isolated from Caralluma tuberculata (1-5), in addition to a known one (russelioside E, 6). The structures of the isolated compounds were elucidated by the analysis of NMR data and FAB-MS experiments. All the isolated compounds were tested for their antimalarial and antitrypanosomal activities as well as their cytotoxicity against human diploid embryonic cell line (...
متن کاملSullivantosides A-F: Pregnane glycosides from Asclepias sullivantii L
Phytochemical investigation of the above-ground biomass of Asclepias sullivantii L. (Asclepiadaceae) afforded six new pregnane glycosides, named sullivantosides A-F (1–6). The structures of 1–6 were elucidated through a variety of spectroscopic and spectrometric techniques (1D and 2D NMR; HRESIMS). To the best of our knowledge, this work represents the first phytochemical study of this species....
