چکیده
Do extrato etéreo das folhas de Vellozia candida Mikan (Velloziaceae) foram isolados os flavonóis 3',4',5,7-tetraidroxi-3,6-dimetoxi-8-metilflavona e 3’,4’,5-triidroxi-3,6,7-trimetoxi-8-metilflavona. Estes compostos foram identificados através de seus dados espectrais, incluindo RMN 2D e EMEM. O derivado 5-hidroxi-3,3’,4’,6,7-pentametoxi-8-metilflavona foi obtido por metilação usando diazometano.

BACKGROUND AND AIMS The genetic structure and variability of two species of Vellozia (Velloziaceae) with restricted distribution in high-altitude quartzitic fields in south-eastern Brazil were studied. Vellozia epidendroides is short, grows on pebbly or sandy soil, and is pollinated by bees. Vellozia leptopetala is arborescent, grows on rock outcrops, and is pollinated by bees and hummingbirds....

UNLABELLED • PREMISE OF THE STUDY We developed and validated microsatellite primers for Vellozia squamata (Velloziaceae), an endemic species of the cerrado (Brazilian savannas), to investigate the influence of different fire regimes on its genetic diversity and population structure. • METHODS AND RESULTS Using a selective hybridization method, we tested 51 SSR loci using a natural populatio...
متن کاملVegatative Architecture of Desiccation-tolerant Arborescent Monocotyledons
Within the monocotyledons the acquisition of the tree habit is enhanced by either primary growth of the axis or a distinctive mode of secondary growth. However, a few arborescent monocotyledons deviate from this pattern in developing trunks up to four meters high that resemble those of tree ferns, i.e., their "woody-fibrous" stems consist mainly of persistent leaf bases and adventitious roots. ...
