EXTRACTION AND CHARACTERIZATION OF IRAQI ARTEMISIA DRACUNCULUS DRIED AERIAL PARTS EXTRACT THOUGH HPLC AND GC-MS ANALYSIS WITH EVALUATION OF ITS ANTITUMOR ACTIVITY AGAINST 7, 12-DIMETHYLBENZE (a) ANTHRACENE INDUCED SKIN CANCER IN MICE
Journal Title: International Journal of Pharmacy and Pharmaceutical Sciences - Year 2017, Vol 9, Issue 5
Abstract
Objective: This study focused on the extraction of bioactive constituents in Iraqi cultivated Artemisia dracunculus L dried aerial parts and phytochemical screening with qualitative estimation of three important flavonols (kampferol, quercetin and rutin). The study also included evaluating the antitumor effects (skin cancer) of methanolic extract for this plant.Methods: Extraction of bioactive constituents was carried out according to standard protocols using 85% methanol. The phytochemical screening has been done using chemical tests and GC/MS with qualitative estimation of three flavonols (kampferol, quercetin and rutin) utilized preparative high-performance liquid chromatography (PHPLC). Skin cancer in mice was induced by using 7, 12-dimethylbenze (a) anthracene to evaluate the antitumor effect of methanolic extract of Artemisia dracunculus when administered orally via intragastric feeding tube. Body weight, tumor volume, tumor burden, percent of tumor incidence and histopathological examination were measured in all tested animals.Results: Phytochemical screening revealed the presence of glycosides, volatile oils, alkaloids, tannin, terpenoids, phenolic compounds and flavonoids. The preparative high-performance liquid chromatography (PHPLC) analysis indicated that rutin had the highest concentration followed by quercetin while kampferol had the lowest concentration. The methanolic extract of the Artemisia dracunculus significantly reduced the percent of tumor incidence, tumor volume and tumor burden of skin cancer in mice (p<0.05).Conclusion: Dried aerial parts of Iraqi Artemisia dracunculus contain many bioactive constituents including three flavonoid compounds (quercetin, kampferol and rutin) that may be responsible for chemo preventive effect exerting by methanolic extract of Artemisia dracunculus against 7, 12-dimethylbenzeanthracine-induced skin cancer in mice.
