Origin and clonal diversity of the parthenogenetic lizard Aspidoscelis rodecki (Squamata: Teiidae): chromosomal evidence
Origin and clonal diversity of the parthenogenetic lizard Aspidoscelis rodecki (Squamata: Teiidae): chromosomal evidence. We analyzed the karyotypes of individuals of two different populations of Aspidoscelis rodecki to investigate the origin and chromosomal diversity of this unisexual lizard. The karyotype of A. rodecki has a diploid number of 50 chromosomes, and exhibits a marked structural h...
متن کاملCytotoxic chalcones and flavanones from the tree bark of Cryptocarya costata.
A new flavanone, 7-hydroxy-5,6-dimethoxyflavanone (1), together with three other flavonoids, didymocarpin (2), 2',4'-dihydroxy-5',6'-dimethoxychalcone (3), and isodidymocarpin (4), had been isolated from the methanol extract of the tree bark of Cryptocarya costata. The structures of these compounds were determined based on spectral evidence, including UV, IR, 1-D and 2-D NMR, and mass spectra. ...

متن کاملIsatinones A and B, new antifungal oxindole alkaloids from Isatis costata.
Two new oxindole alkaloids isatinone A (1) and B (2) have been isolated from Isatis costata, along with the known trisindoline. Their structures have been assigned on the basis of spectroscopic techniques and chemical studies. Both new compounds showed significant antifungal activity.
