Two new 19-hydroxy bufadienolides, named bufohydrolide A (1) and bufohydrolide B (2), and four known analogs (3-6) were isolated from the aqueous extracts of the skins of Bufo melanosticus. Their structures were established by spectral data analyses, such as UV, IR, 1 D/2D NMR and mass spectra. Compounds 1-6 were evaluated for their cytotoxic activity against SMMC-7721, HT-29 and A549 cells. Noteworthily, all six isolates exhibited various levels of anti-proliferative activities with IC50 values ranging from 0.02 ± 0.00

Genebanks provide access to diverse materials for crop improvement. To utilize and evaluate them effectively, core collections, such as the World Rice Core Collection (WRC) in the Genebank at the National Agriculture and Food Research Organization (NARO) have been developed. Because the WRC consists of 69 accessions with a high degree of genetic diversity, it has been used for more than 300 projects. To allow deeper investigation of existing WRC data and to further promote research using genebank rice accessions, we performed whol
