Withanolides from Withania adpressa

Helvetica Chimica Acta, 2007
AbstractFrom the leaves of Withania adpressa, a plant endemic to Sahara of Morocco and Algeria, the novel steroidal lactone (22R)‐14α,15α,17β,20β‐tetrahydroxy‐1‐oxowitha‐2,5,24‐trien‐26,22‐olide (= (15S,17S)‐14,15,17,20‐tetrahydroxy‐22,26‐epoxyergosta‐2,5,24‐triene‐1,26‐dione; 1), was isolated, along with three known compounds, withanolides F (2), J (3)

Withanolides from Withania somnifera roots

Phytochemistry, 2008
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. Among the known compounds, Viscosa lactone B, stigmasterol, stigmasterol glucoside and alpha+beta glucose are being reported from the roots of W ...

Withanolides from Jaborosa laciniata

Journal of Natural Products, 2007
Six new trechonolide type withanolides (compounds 1- 6), together with trechonolide A, jaborotetrol, and 12- O-methyl jaborosotetrol, were isolated from the aerial parts of Jaborosa laciniata. The structures were elucidated on the basis of spectroscopic methods (1D and 2D NMR, MS).
