16-hydroxylated withanolides from Exodeconus maritimus
In addition to the known compounds withanolide A (4), withanone (5), and NIC-3 (6), three 16-hydroxylated withanolides were isolated from Exodeconus maritimus. The new withanolides were identified as 6α,7α-epoxy-5α,16β- dihydroxy-1-oxowitha-2,17(20),24-trienolide (exodeconolide A, 1), 6α,7α- epoxy-5...
