Dehydrovomifoliol could be a marker of Polish heather honey. Dehydrovomifoliol exhibits moderate acetylcholinesterase (AChE) inhibitory activities. Dehydrovomifoliol shows significant cytotoxic activities against three human cancer cell lines, namely, HONE-1 nasopharyngeal, KB oral epidermoid carcinoma, and HT29 colorectal carcinoma cells, and the IC(50) values in the range 3.7-8.1 microM.
Vomifoliol is most likely the immediate precursor of dehydrovomifoliol, because of the organism converted abscisic acid (ABA), to dehydrovomifoliol as the major metabolise, and a cell-free extract exhibits vomifoliol dehydrogenase activity. Vomifoliol and
