Title: Withanolides from Jaborosa kurtzii.

Authors: Ramacciotti NS, Nicotra VE.

Abstract: Two new withanolides were isolated and characterized from the aerial parts of Jaborosa kurtzii, namely, jaborosalactone 43 (1), with a spiranoid delta-lactone at C-22, and jaborosalactone 44 (2), a 12-oxowithanolide, which may function as a biosynthetic precursor to 1. These new compounds were fully characterized by a combination of spectroscopic methods. Compound 1 showed selective phytotoxicity toward a dicotyledon species, Lactuca sativa (lettuce).
