Biosynthesis of Furocoumarins
The Authors have studied the biosynthesis of some furocoumarins contained in Ruta graveolens. Labeled 5,7and 7,8-dihydroxycoumarins have been administered to the herb, however practically no incorporation of radioactivity was observed in the isolated furocoumarins. Moreover, with the aim to study in a more detailed way the role of rutaretin and marmesin, trapping experiments have been performed...
متن کاملCarbohydrates from Detarium microcarpum bark extract.
The bark extract of the medicinal plant Detarium microcarpum was analysed for its carbohydrate content by GLC-CIMS. Preparative HPLC of the benzoylated carbohydrate fraction led to the isolation of L-quino-1,5-lactone, D-(-)-bornesitol, D-pinitol, myo-inositol, sucrose, D-glucose, and D-fructose benzoates, which were characterised by NMR spectroscopy experiments.
متن کاملDark and photohemolysis of erythrocytes by furocoumarins.
It has been shown that various furocoumarins are able to cause dark hemolysis in red blood cells (RBC). However, this effect is evident only at relatively high furocoumarin concentrations (4.6 x 10(-4) M) - much higher than those used in photosensitization experiments or photochemotherapeutic treatments. Among the various furocoumarins examined in this study, only psoralen (Ps) and 3-carbethoxy...
متن کاملCoumarins, Xanthones and Related Compounds.
It has long been known that coumarins (α-pyrones) and xanthones (γ-pyrones) together form a large class of naturally occurring compounds exhibiting a wide range of biological activities. However, the interest of the scientific community for these secondary metabolites, as well as for their structural analogues, has never decreased since these “old compounds” are constantly generating promising—...
