The first withanolide with a spiranoid y-lactone side chain, jaborosalactone P (77), was isolated from plants of Jaborosa odonelliana collected in Salta province (Argentina) [43]. Lately six structurally related compounds were found in the same plant, jaborosalactones 10 (78), 14 (79) and 15 (80) in plants collected in summer and jaborosalactones 11 (81), 12 (82), 13 (83) and 14 (79) in plants collected in autumn [44]. [Pg.1032]

Recently withanolides isolated from Iochroma australe and the norbomane-type withanolide jaborosalactol 18 (3) isolated from Jaborosa bergii, showed phytotoxic activity on monocotyledoneous and dicotyledoneous species. Iochroma australe extract and the major constituent (17S,20R,22R)-4p,7(3,20-trihydroxy-l-oxowitha-2,5,24-... [Pg.1048]

Many withanolides, such as jaborol (9), reported from plants of genus Jaborosa, have a skeleton with aromatic ring A [21]. [Pg.3469]

These withanolides have an additional ring that arises by the linkage of C-15 and C-17 of ring D. Jaborosalactol 18 (16) is among the first members of the norbomane-type of withanolides, isolated from the aerial parts of Jaborosa bergii [30]. [Pg.3472]

These withanolides are formed by the double oxidation of C-22, leading to the formation of an ether linkage between C-12 and C-22 and a spiranoid -lactone at C-22. Examples include jaborosalactones 27 (18) and 28 (19), isolated from Jaborosa rotacea [31]. [Pg.3472]
