THE STRUCTURAL ELUCIDATION OF NEW POLYOXYGENATED CYCLOHEXENES FROM UVARIA GRANDIFLORA
-
Abstract
Four new polyoxygenated cyclohexenes, named uvarigranol A(1), B(2), E(3) and F(4), along with the known zeylenol were obtained from the roots of Uvaria grandiflora Roxb (Annonaceae). Based on spectral and X-ray analysis as well as Mosher methodology, their structures and absolute configuration were established.
