Two new polyoxygenated cyclohexenes, kweichowenol A and B were isolated from the leaves of Uvaria kweichowensis and their structures were established on the basis of their spectral data.
Two new polyoxygenated cyclohexenes, named uvacalolA (1),and B (2) were isolated from the rhizomes of Uvaria calamistrata. On the basis of spectral analysis and chemical derivatization, including preparation of Mosher...
Two new polyoxygenated cyclohexenes,named uvarigranol E (I) andF(VII),were isolated from the rhizome of Uvaria grandiflora. On the basis ofspectral analysis and chemical derivatizations, including preparation of Moshe...
Two new polyoxygenated cyclohexenes, uvarigranol A and uvarigranol B, together with the known zeylenol were isolated from the roots of Uvaria grandiflora Roxb(Annonaceae). Their structures were established on the base...
