••
TL;DR: The structure of a new chlorinated withanolide isolated from the hybrid plants of Withania somnifera, chemotypes III (Israel) by Indian I, is established as the chlorohydrin of withanolides D (6α-chloro-4β,5β,20αF-trihydroxy-l-oxo-22R-witha-2,24-dienolide) as discussed by the authors.

TL;DR: In this paper, the inheritance characteristics of various substituents on the withanolide skeleton were analyzed based on the occurrence in per cent of each substituent in relation to the total withanolides content in the hybrid plants and their respective parents.

TL;DR: In this paper, the first 14β-substitution among withanolides, was isolated with Withania somnifera and its structure established by X-Ray analysis. But it is not known whether the 14β substitution can be applied to other withanone derivatives.
Abstract: 14β-Hydroxywithanone (1), the first example of a 14β-substitution among withanolides, was isolated with Withania somnifera and its structure established by X-Ray analysis.
