Alkaloids and Flavone Acyl Glycosides from Acanthus arboreus
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...
متن کاملFlavones and Flavone Glycosides from Salvia macrosiphon Boiss
Salvia genus, which is generally called Maryam-Goli in the Persian language, belongs to Lamiaceae family and comprises 58 species in Iran. Four flavonoids plus a steroid compound were isolated from the ethyl acetate and methanol extracts of the aerial parts of Salvia macrosiphon Boiss, using different chromatographic methods on the silica gel and sephadex LH20. The structures of the isolated co...

متن کاملTwo New Cyclolignan Glycosides from Acanthus ilicifolius
Acanthus ilicifolius L. (Acanthaceae) is a spiny herb of mangrove widely distributed in southeastern Asia. In traditional Chinese medicine, it is used as an anti-inflammatory and anti-hepatitis agent. Previous pharmaceutical studies on this plant revealed that the crude alcoholic extract of its leaves showed antioxidant, hepatoprotective, antitumour and anticarcinogenic effects [1 – 2]. The con...
متن کاملFlavones and flavone glycosides from Halophila johnsonii.
Halophila johnsonii Eiseman is a shallow-water marine angiosperm which contains UV-absorbing metabolites. Studies on methanol extracts of H. johnsonii by means of HPLC-UV, NMR, HPLC-MS resulted in isolation and identification of seven previously unknown flavone glycosides: 5,6,7,3',4',5'-hexahydroxyflavone-7-O-beta-glucopyranoside (1), 5,6,7,3',4',5'-hexahydroxyflavone-7-O-(6''-O-acetyl)-beta-g...
