Jaborosa caulescens (Jaborosa caulescens)
Description
Withanolides 2,3-dihydrotrechonolide A and 2,3-dihydro-21-hydroxytrechonolide A were isolated along with two known withanolides trechonolide A and jaborosalactone 39 from Jaborosa caulescens var. bipinnatifida (Solanaceae). The structures of 1�2 were elucidated through 2D NMR and other spectroscopic techniques. In addition, the structure of withanolide 1 was confirmed by X-ray crystallographic analysis.
