RESEARCH ON NIGELLA SATIVA L. (RANUNCULACEAE) MUCILAGE

REZUMAT Lucrarea de fa]\ constituie o analiz\ chimic\ asupra p\rtilor aeriene f\r\ semin]e ale speciei Nigella sativa (Ranunculaceae). Pentru prima dat\ in literatur\ a fost semnalizat\ prezen]a mucilagiilor intr-un procent de 4,8% in p\r]ile aeriene [i r\d\cinile speciei Nigella sativa (Ranunculaceae). Cu ajutorul unui procedeu de cromatografie pe strat sub]ire cuplat cu fotodensitometrie au fost eviden]iate componentele mucilagului, precum [i procentele lor de combinare: acid galacturonic (26,08%), acidglucuronic (11,40%), galactoz\ (12,39%), glucoz\ (18,21%), arabinoz\ (20,03%), ramnoz\ (11,89%). Cuvinte cheie: nigella sativa, ranunculaceae, mucilag, cromatografie pe strat sub]ire, fotodensitometrie The paper presents the chemical analysis of Nigella vegetal species, of the aerial, seedless parts of the plant. It is pointed out for the first time the presence of 4.8% mucilages in the aerial part (herba) and root (radix) of Nigella sativa (Ranunculaceae). As a result of thin layer chromatography and photodensitometric evaluation of chromatograms, galacturonic acid (26.08%), glucuronic acid (11.40%), galactose (12.39%), glucose (18.21%), arabinose (20.03%) and rhamnose (11.89%) were indentified and assayed as the components of mucilage.
