Quassinoids and Their Chemotaxonomic Significance
The quassinoids are a group of complex, highly oxygenated, degraded triterpene mostly found in Simaroubaceae family. Two quassinoids (degraded triterpenes), 1 and 2 were isolated first time from the stem bark of Ailanthus excelsa. Compound 1 is C19 quassinoid. C19 quassinoid derived biogenetically from a C20 quassinoid, via a 1,2 – dioxo derivative. The structural elucidation is based on the an...
متن کاملQuassinoids from the Root of Eurycoma longifolia and Their Antiproliferative Activity on Human Cancer Cell Lines
BACKGROUND The roots of Eurycoma longifolia Jack have traditionally been used as an aphrodisiac tonic besides the other remedies for boils, fever, bleeding gums, and wound ulcer. Recently, the antiproliferative activity of E. longifolia has been reported and remained attractive to natural chemists. OBJECTIVE The objective of this study was to study on antiproliferative compounds from the root...
متن کاملBiological flora of Central Europe: Ailanthus altissima (Mill.) Swingle
Ailanthus altissima (tree of heaven), Simaroubaceae, is an early successional tree, native to China and North Vietnam, which has become invasive in Europe and on all other continents except Antarctica. It is most abundant in urban habitats and along transportation corridors, but can also invade natural habitats. This paper reviews the literature on the morphology, distribution, ecology, habitat...
متن کاملAnti-plasmodial activity of Ailanthus excelsa.
The anti-plasmodial activity of Ailanthus excelsa stem bark was investigated. The methanolic extract inhibited in vitro growth of chloroquine-sensitive (D10) and resistant strains (W2) of Plasmodium falciparum (IC50 4.6 and 2.8 microg/ml, respectively). The effect was retained in the chloroform fraction (3.1 and 2.1 microg/ml, respectively). The anti-plasmodial activity could be ascribed to the...
متن کاملTwo new Cu(II) and Zn(II) Schiff base complexes: Synthesis, characterization and their biological activity
New two nano- sized Schiff base complexes [M(L)], where L= 2, 2'-((1E, 1E')-(1, 2 phenylen bis (azanylylidene)) bis (methanylylidene)) bis (4-bromo phenolato) and M=Cu or Zn, (a, b complexes) were synthesized by ultrasonic irradiation. These complexes were characterized by elemental analysis, molar conductivity, FT-IR, fluorescence emission, 1H NMR, field emission scanning electron spectroscopy...
