Uvaria rufa Blume, locally knows as “Pe-Puan-Noi”, is a climber shrub plant distributed mainly in tropical rainforest areas of Thailand. An alcoholic tincture of its roots is used ethnomedically as ecbolic . Previous phytochemical studies of this plant have revealed the presence of flavonoids, tectochrysin, 7-O-methylwogonine, and 6,7-O,O-dimethylbaicalein from the bark  and 2,5-dihydroxy-7-methoxyflavanone from the roots . (E)-3,7-Bisbenzoyloxyhept-4-en-1,2,6-triol  and highly oxygenated cyclohexenes (zeylenol, ellipeiosol B, and ferrudiol)  were also isolated from the leaves of this plant. In continuation of our phytochemical investigation of this plant, we isolated 13 compounds (1–13), one flavonoid (8), and four alkaloids (9, 11–13) were isolated from this plant for the first time. To our knowledge, this is...
