A HIGHLY EFFICIENT PREPARATION OF LUNULARIC ACID AND SOME BIOLOGICAL ACTIVITIES OF STILBENE AND DIHYDROSTILBENE DERIVATIVES

Article abstract of DOI:10.1016/0031-9422(88)80599-5

Lunularic acid, an acid possessing dormancy inducing, antifungal, thromboxane synthetase and hyaluronidase inhibitory and plant growth inhibitory activities, was obtained quantitatively from hydrangenol by reduction using sodium borohydride-palladium chloride.Some stilbene and dihydrostilbene derivatives prepared from hydrangenol and its glucoside also showed plant growth inhibitory, hyaluronidase inhibitory and piscicidal activities.Key Word Index - Lunularic acid; dihydrostilbenes; stilbenes; hydrangenol; dihydroisocoumarin; sodium borohydide-palladium chloride reduction; dormancy; plant growth inhibitory activity; piscicidal activity; hyaluronidase inhibitory activity.
