Withanolides with phytotoxic activity from Jaborosa caulescent var. caulescens and J. caulescens var. bipinnatifida

Seven new withanolides (1-7) were isolated from the aerial parts of Jaborosa caulescens var. caulescens and Jaborosa caulescens var. bipinnatifida. Three of the new compounds are related to jaborosalactones R, S, and T with a δ5-lactone side chain and a hemiketal (or ketal) ring formed between a 21-...
