“…The withanolide composition ofthe F 1 offspring of the cross between chemotype III and the Indian chemotype was significantly different from those of the parents. Most significantly, this hybrid yielded a withanolide with a 14~-hydroxyl group (14) which is rather unique within withanolides (63,195,197). The results suggest that it might be possible to develop hybrids with the ability to yield tailored withasteroids to meet specific needs.…”

“…The data were compared with the corresponding shifts in withanone (5a) and 14P-hydroxywithanone (5b). 8 The pyridine-induced shifts in withanone (14a-H; 17a-OH) indicate a significant deshielding effect of 17a-OH on the signal of 21-H3, but not on that of 18-H3. This is in agreement with the relative positon of 18-H3 with respect to 17a-OH (dihedral angle of cu.…”
