چکیده

Further study of constituents from the aerial parts of Asclepias tuberosa afforded twenty-two new steroidal glycosides along with tuberoside B(5) and G(5). These glycosides were confirmed to contain 8,12;8,20-diepoxy-8,14-secopregnanes, tuberogenin and its congeners, as their aglycones. The structure of each of these compounds was elucidated based on the interpretation of NMR and MS measurements and from chemical evidence.

An androstane bioside and 3'-thiazolidinone derivatives of doubly-linked cardenolide glycosides from the roots of Asclepias tuberosa.

Steroidal compounds in the roots of Asclepias tuberosa were investigated and 17alpha-hydroxyandrosta-4,6,15-trien-3-one 17-O-alpha-L-arabinopyranosyl-(1-->6)-beta-D-glucopyranoside, termed ascandroside, was isolated from the CHCl3-soluble fraction. Among five doubly-linked cardenolide glycosides, two were identified as 3'-spiro-linked thiazolidinone (4) and S-oxythiazolidinone derivatives (5) o...

Cardenolide and oxypregnane glycosides from the root of Asclepias incarnata L.

Twenty-nine new oxypregnane glycosides were obtained along with two known cardenolides, frugoside and gofruside, and three known 12-O-acylated pregnane glycosides from the roots of Asclepias incarnata L. (Asclepiadaceae). By detailed studies of the 1H- and 13C-NMR spectra, the structures were determined to be tri- to penta glycosides of isolineolon, 12-O-acetyllineolon, ikemagenin, 12-O-benzoyl...

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....

Iridoid and phenylethanoid glycosides from Phlomis tuberosa L.

A new iridoid glucoside, 8-O-acetylshanzhiside (1), was isolated from the aerial parts of Phlomis tuberosa, together with two known iridoid glucosides, shanzhiside methyl ester and lamalbide. The known phenylethanoid glycosides acteoside and forsythoside B were also obtained and characterized. The structure of 1 was determined by means of 1D- and 2D-NMR spectroscopic evidence.
