| Phytochemistry. 2008 Feb;69(4):1000-4. | | Withanolides from Withania somnifera roots.[Pubmed: 18061221] | Two new and seven known withanolides along with beta-sitosterol, stigmasterol, beta-sitosterol glucoside, Stigmasterol glucoside, alpha+beta glucose were isolated from the roots of Withania somnifera.
METHODS AND RESULTS:
Among the known compounds, Viscosa lactone B, stigmasterol, Stigmasterol glucoside and alpha+beta glucose are being reported from the roots of W. somnifera for the first time. One of the new compounds contained the rare 16beta-acetoxy-17(20)-ene the other contained unusual 6alpha-hydroxy-5,7alpha-epoxy functional groups in the withasteroid skeleton.
CONCLUSIONS:
The structures were elucidated by spectroscopic methods and chemical transformations. | | Planta Med.,1973 Mar;23(2):145-8. | | Stigmasterol glucoside a constituent of Adenanthera pavonina seed and leaf.[Pubmed: 4705793 ] | | Stigmasterol glucoside, dulcitol, a polysaccharide and free stigmasterol from the seeds and octacosanol, dulcitol, glucosides of β–sitosterol and stigmasterol from the leaves have been isolated and characterised. Stigmasterol, Stigmasterol–β–D–glukosid, Dulcitol und ein Polysaccharid aus den Samen und Glukoside von β–Sitosterol und Stigmasterol, Octakosanol und Dulcitol aus den Bl01ttern der Adenanthera pavonina Linn. wurden isoliert und charakterisiert. |
