A cytotoxic flavone from Scoparia dulcis L.
In a continuation of our studies on biologically active substances of the Paraguayan crude drug,"Typychd kuratir(Scoparia dulcis L.,Scrophulariaceae),1)we isolated a polyoxygenated flavone(1),which was found to exhibit cytotoxicity against human cultured cells such as HeLa 229,2)HeLa S3,3)HEp-2,4)FL,5)Chang liver6)and intestine 4077)cells. Some flavonoids have been reported to be cytotoxic to K...
متن کاملQuinocitrinines A and B, new quinoline alkaloids from Penicillium citrinum Thom 1910, a permafrost fungus.
In the course of our previous work we isolated alkaloids such as agroclavine-I and epoxy-agroclavine-I from Penicillium citrinum VKM FW-800 as a microorganism isolated from permafrost1,2). This fungus was shown to coproduce two other alkaloid compounds, which were extractable only under acidic conditions. Positive staining by Dragendorff's reagent but negative Ehrlich reaction suggested the occ...
متن کاملQuinolactacide, a new quinolone insecticide from Penicillium citrinum Thom F 1539.
By a screening program searching for new pesticides from fungal sources, an insecticidal compound was isolated from Penicillium citrinum F 1539. The compound, named quinolactacide, was novel and showed 88% mortality against green peach aphids (Myzus persicae) at 250 ppm. Its structure was determined by spectroscopic techniques.
متن کاملAntisickling and toxicological evaluation of the leaves of Scoparia dulcis Linn (Scrophulariaceae)
BACKGROUND Scoparia dulcis Linn (Scrophulariaceae) together with other medicinal plants serve as antisickling remedies in Africa. This study was aimed at investigating the antisickling activity of the leaves of the plant as well as establishing the toxicological profile. METHOD Chemical tests were employed in phytochemical investigations. Evaluation of the antisickling activity involved the i...
متن کاملEvaluating in vitro antioxidant activity and GC-MS analysis of Scoparia dulcis Linn (Scrophulariacae)
Article history: Received on: 09/04/2015 Revised on: 07/05/2015 Accepted on: 21/05/2015 Available online: 27/07/2015 Free radical scavenging activity was observed in both the methanol extract (M.E) and aqueous extract (A.E) of Scoparia dulcis respectively. In this study significant free radical scavenging activity was determined by evaluating the inhibition concentration (IC50) in each test. In...
