anti-inflammatory effects of dioscorea alata l. anthocyanins in a tnbs-induced colitis model.	the purple yam, dioscorea alata l., is an important source of starch, vitamins and polyphenols. five different pigments from the purple tubers of this plant were separated by high-performance liquid chromatography-mass spectrometry, and the anthocyanin fraction (dacn) was collected. the anti-inflammatory effects of dacns were investigated at different concentrations and compared with the standard colitis treatment, 5-aminosalicylic acid, in a trinitrobenzenesulfonic acid (tnbs)-induced colitis m ...	2017	28121001
a single molecular marker to distinguish between species of dioscorea.	yams are species of the genus dioscorea (family dioscoreaceae), which consists of approximately 630 species. the majority of the world production of yams occurs in africa with 58.8 million t annually, but they are also produced in the americas and asia. the saponins in yams have been reported to possess various properties to improve health. the tuber and aerial parts of various species often share morphological similarities, which can cause problems in the proper identification of sample materia ...	2017	28092170
the genome sequence of dioscorea bacilliform tr virus, a member of the genus badnavirus infecting dioscorea spp., sheds light on the possible function of endogenous dioscorea bacilliform viruses.	the complete genome sequence of dioscorea bacilliform tr virus (dbtrv) was determined. the closest relatives of dbtrv are dioscorea bacilliform al virus (dbalv) and dioscorea bacilliform rt virus 1 (dbrtv1). specific primers were designed and used to determine the prevalence of dbtrv in a yam germplasm collection. it was found that this virus infects dioscorea alata and d. trifida plants in guadeloupe and french guyana. dtrbv was not detected in any of the tested d. cayenensis-rotundata accessio ...	2017	27770216
protective effects of dioscorea alata l. in aniline exposure-induced spleen toxicity in rats: a biochemical study.	present study was designed to evaluate the protective effects of ethanolic extract of dioscorea alata l. (da) on hematological and biochemical changes in aniline-induced spleen toxicity in rats.	2017	25948969
characterizing genotypic variation in biochemical composition, anti-nutritional and mineral bioavailability of some nigerian yam (dioscorea spp.) land races.	the aim of this study was to characterize 43 genotypes from five yam species [dioscorea rotundata (poir), dioscorea alata (linn), dioscorea bulbifera (linn), dioscorea cayenensis (lam) and dioscorea dumetorum (kunith) pax] which are major land races in nigeria in terms of their chemical composition, nutritional, anti-nutritional and mineral bioavailability. findings showed that there was genotypic variation in terms of chemical composition, mineral profile and bioavailability of the minerals amo ...	2018	29358812
