Caulescens var. bipinatifida Recent Insights on the Chemistry and Pharmacology of Withasteroids 23 denominated jaborosalactones 39 (183), 40 (181), 42 (179) and, 12-0ethyljaborosalactone 42 (180), besides two compounds from J. caulescens var. caulescens, jaborosalactone 38 (186) and 18-0-methyljaborosalactone 38 (187). These metabolites have in their structure a hemiketal ring formed between a hydroxyl group in C-21 and a carbonyl in C-12, but they keep a 8lactone in the side chain, characteristic of the withanolides.
