Withanolides from Physalis hispida

Journal of Natural Products, 2014
Nine new withanolides (1-9), withahisolides A-I, were isolated along with nine known compounds (10-18) from the aerial parts of Physalis hispida. The structures of 1-9 were elucidated through a variety of spectroscopic techniques, while the structures of 1 and 2 were confirmed by X-ray crystallographic analysis. Compounds 1-3 are the first withanolides

Cytotoxic withanolides from Acnistus arborescens

Phytochemistry, 2002
Three cytotoxic withanolides, two with new structures, were isolated from the leaves of Acnistus arborescens and their structures determined by a combination of 1D and 2D NMR, mass spectral, and molecular modeling studies. Dereplication analysis of the ethyl ether extract was useful for evaluating the components showing significant cytotoxic activity.

Plantagiolides K–N, three new withanolides and one withanolide glucoside from Tacca plantaginea

Fitoterapia, 2015
Phytochemical investigation of the whole plants of Tacca plantaginea led to the isolation of 3 new withanolides and one new withanolide glucoside, named plantagiolides K-N (1-4), together with one known withanolide, 4 known withanolide glucosides, and 2 known taccalonolides. Their structures were elucidated by extensive spectroscopic analysis. Compound

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 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).
