• Antioxidant: Free Radical Scavenging Activity of Scoparia dulcis Extract: Study showed strong antioxidant activity corresponding to the reduction of hydroxyl radical generation, a possible rationale for the weeds observed therapeutic effects.
• Antioxidant / Anti-Diabetic: Study showed significant decrease in TBARS and hyperperoxides formation in the brain of rats suggesting a role in protection against lipid peroxidation induced membrane damage. Results suggest, in addition to its antidiabetic effect, SD possess antioxidant potential.
• Antihyperglycemic / Polyol Pathway: Effect of an aqueous extract of Scoparia dulcis on blood glucose, plasma insulin and some polyol pathway enzymes in experimental rat diabetes: Study showed SD was effective in attenuating hyperglycemia in rats, possibly due to the decreased influx of glucose into the polyol pathway with increased activities of antioxidant enzymes and plasma insulin and decreased activity of sorbitol dehydrogenase.
• Anti-Diabetic: Study showed the aqueous extract of Scoparia dulcis exhibited antihyperglycemic effect by attenuating biochemical alterations in streptozotocin-induced diabetic rats.
• Cytoprotective / Insulin-Secretagogue Activity: Study showed significant decrease in blood glucose with significantly increased plasma insulin level with use of aqueous extract of S dulcis in STZ-induced diabetic rats. Other results showed its insulin secretagogue activity and protection against STZ-mediated cytotoxicity. The glucose lowering effect was associated with potentiation of insulin release from the pancreatic islets.
• Anti-Ulcer: Study showed water extracts of S dulcis showed dose-dependent inhibition of indomethacin-induced gastric damage in rats validating its use in traditional medicine as an antacid and anti-ulcer agent.
• Antioxidant: Protective role of Scoparia dulcis plant extract on brain antioxidant status and lipid peroxidation in STZ diabetic male Wistar rats. Study showed levels of peroxidation markers in the brain were significantly a role in protection against lipidperoxidation-induced membrane damage.
• Anti / Antifungal: Study of isolated fractions showed significant antimicrobial and antifungal activity against all tested organisms – S typhii, S aureus, E coli, B subtilis, P aeruginosa, P vulgaris and fungal strains (C albicans, A niger and F oxysporum).
• Antitumor / Scopadulcic Acid B: Scopadulcic acid B (SDB), a tetracyclic diterpenoid isolated from S dulcis, inhibited the effects of a tumor promoter, inhibited phospholipid synthesis and suppressed the promoting effect of TPA on skin tumor formation. Its potency is stronger than other natural anti-tumor promoting terpenoids. (7)
• Antihyperlipidemic: Effect of Scoparia dulcis (Sweet Broomweed) in Streptozotocin Diabetic Rats: Study showed antidiabetic and antihyperlipidemic activity in normal and experimental diabetic rats.
• NGF Activity: Acetylated Flavonoid Glycosides Potentiating NGF Action from Scoparia dulcis: Three new acetylated flavonoid glycosides were isolated, two of which showed enhancing activity of nerve growth factor-mediated neurite outgrowth.
• Cytotoxicity: Study isolated four new diterpenes. Crude extracts and pure diterpenes suggested cytotoxicty.
• Scoporic Acid A / Beta-glucoronidase Inhibitor: Study isolated three labdane-type diterpene acids: scoparic acid A, B and C. Scoporic acid A was found to be a potent beta-glucoronidase inhibitor.
• Hepatoprotective / Antioxidant: Study isolated showed the hydroalcoholic extract of S dulcis exhibits significant hepatoprotective activity against carbon tetrachloride-induced liver damage in rats, an activity attributed to free radical scavenging activity.
• Anti-Trypanosomal Immunosuppression / Immunological Boosting: Previous findings suggest T. brucei is immunosuppressive. Study showed Scoparia dulcis provides a measure of immunological boost during experimental T. brucei infection in rabbits.
• Sympathomimetic Effects / Catecholamines: Study yielded both noradrenaline and adrenaline in the plant extract. The catecholamines may be responsible for the hypertensive and inotropic effects after parenteral administration of S dulcis extracts.
• Anti-Urolithiasis: Study investigating the inhibition of calcium oxalate, calcium phosphate and calcium carbonate mineralization by five medicinal plants – A aspera, P leschenaultii, S amplexicaulis, Scoparia dulcis and A lanata – showed that increased intake of the fruit juices and seed extracts of the test plants would be helpful in urinary stone prophylaxis. The sequestering of the insoluble calcium salts by the fruit juices may be due to single or mixed ligand chelation by the hydroxyl acids present in them.
• Anti-Inflammatory / Analgesic: Study results indicate that the extract of S dulcis possess analgesic effects probably related to its antiinflammatory activity, effects probably attributable to the presence of glutinol and flavonoids.
• Pro Blood Clotting Activity: Study investigated the effect of a decoction of S. dulcis on blood clotting time in rats. Results showed significant reduction in clotting time. The proclotting activity was faster than vitamin K.
• Anti-Malarial / Scopadulcic acid A: Phytochemical screening yielded pharmacologically active compounds scopadulcic acid A (SDA) and scopadulcic acid B (SDB), and semisynthetif analogues. SDB has shown antiviral activity against Herpes simplex virus 1 and antitumor activity against various human cancer cell lines, and potent inhibitory activity against gastric proton pumps. Pure SDA was tested and found to have in vitro activity against P. falcifarum.
