Abstract:

Quantitative determination of rutin in Ruta Graveolens, L. which is easily cultivated in Iran, is necessary for its economic importance, diversity of specialities and their pharmacological activity in blood vessels disorders. For this purpose, the plant was cultivated in botanical garden of Tabriz University of Medical Sciences and rutin was determinated at different stages of plant growth. The extraction was done from the crude plants by ethanol, boiling water and hydroalcoholic solvents. Rutin was subsequently purified by crystalization."nStructure elucidation was confirmed by the U.V spectrum in the presence of shift-producing reagents, and TLC by using different systems, HPLC and HPTLC in the presence of standard."nSugars and their sequence of bonding to genine were known by acidic hydrolysis, sequential hydrolysis and TLC in the presence of standards. For quantitative determinations of rutin two methods were selected i.e. HPLC and colorimetery. In the colorimetrey method, cyanidin reaction was used for color producing and the absorbances of other compounds of extract were eliminated in coincidence with rutin absorption.. In the HPLC method, separation was done on CN- column with mobile phase including dioxan/phosphate bnffer (pH=2.6); 2:8. In the end the results of two methods were compared.
