Reaction of a beta-(1 --> 4) linked galactan with TDMS chloride followed by methylation and desilylation yields methyl galactans with unconventional functionalization patterns. The products were characterized via FTIR and NMR of the intact polymer and by CE after controlled depolymerization. A TDMS-derivatized methyl galactan contains differently methylated secondary hydroxyl groups. SEC and an...
O estudo fitoquímico de Acanthus arboreus resultou no isolamento de 3 novos alcalóides: 6hidróxi-2-benzoxazolinona, 4-hidróxi-acantamina (3,4-di-hidróxi-1,4-benzoxazino-2-ona) e acantaminosídeo (3-O-glicopiranosídeo-1,4-benzoxazino-2-ona). Além destes alcalóides foi também isolado o novo flavonóide 7-O-β-D(6”-trans-p-cumaroil)3”-O-acetilglicopiranosídeo apigenina e os seguintes compostos de est...
to identify the larvicidal activities of silver nanoparticles synthesized with acanthus ilicifolius (a. ilicifolius) leaf extract against the larvae of armigeressubalbatus and aedesaegypti. in vitro larvicidal activities such as lc50 and lc90 were assessed for the a. subalbatus and ae.aegypti larval species. further, characterization using different techniques such as uv, sem,edax, xrd and fti...
Cervical cancer is second only to breast in terms of incidence; however, it the most lethal form among Thai women due asymptomatic nature its early stages. This work aimed examine cytotoxic and antiproliferative capacities Rhinacanthus nasutus (RN) Acanthus ebracteatus (AE) extracts against human cervical cells (HeLa). Plant leaves were used for ethyl acetate extraction. The antioxidant assays,...
Parasites are well-known to alter the behavior of their hosts, but there is still a paucity of knowledge about how parasites modify the behavior of many ecologically influential host species. I studied the keystone grazer, the salt marsh periwinkle (Littoraria irrorata), to determine the influence of infection by the digenetic trematode, Parorchis acanthus, on its grazing behavior. Comparative ...
