• Radical Scavenging Activity / Phenolic Content: Study showed the phenolic content to be highest in the ethanol fraction. The free radical scavenging activity was higher than the control synthetic antioxidant. Results suggest the plant can serve as a source of natural antioxidants and preservative agents with potential applications in the food industries. (1)
• Anti-Asthmatic: Study showed the C sophera extract significantly protected the bronchoconstriction in guinea pigs against histamine-induced bronchospasm. Animals pretreated with the parent extract and fraction showed significant (p<0.005 inhibition in reducing paw edema in passive paw anaphylaxis. (4)
• Seed Oil Constituents: Study of seed oil yielded 43 compounds. The major constituents were palmitic acid (22.82 %), linoleic acid (8.32 %), elaidic acid (19.16 %), stearic acid (9.86 %) among others. (6)
• Hepatoprotective: Study of ethanol extract of C. sophera in paracetamol-induced hepatotoxicity in rats showed remarkable hepatoprotective activity. (7)
• In Vitro Thrombolysis / Cytotoxicity Study: An in vitro thrombolytic model evaluated the clot lysis effect of six Bangladesh herbal extracts including Senna sophera L. Senna sophera showed 31.61 ±2.97% clot lysis. In brine shrimp cytotoxic assay, it showed 233.37 ±7.74 µg/ml, with reference to vincristine sulfate (LC50 0.76 ±0.04). (9)
• Hepatoprotective / Carbon Tetrachloride: Study evaluated the hepatoprotective activity of ethanolic extracts of C. sophera leaves against CCl4-induced hepatic damage in adult wistar rats. Results showed potent hepatoprotective action which may be due to the presence of flavonoids in the extracts. (10)

• Antibacterial / Leaves: Study evaluated an alcoholic leaf extract of C. sophera for antibacterial potential against various uropathogenic bacteria. Results showed good antibacterial activity with maximum activity against E. coli, K. pneumonia, and P. aeruginosa, with moderate activity against S. saprophyticus, P. mirabilis and C. freundii. (15)
• Analgesic/ Anticonvulsant / Seeds: Preliminary screening of seed extract of Cassia sophera L. var. purpurea Roxb. exhibited analgesic, anticonvulsant effects and potentiated pentobarbitone sleeping time. (17)
• Antinociceptive / Antipyretic / Leaves: Study of a crude hydroalcoholic extract of CS leaves showed significant analgesic activity using acetic acid induced writhing and central analgesic activity by heat-induced pain in mice and significant dose-dependent antipyretic activity using Brewer's yeast induced pyrexia in rodents. (18)
• Diuretic / Laxative: Study evaluated the diuretic and laxative activity acute toxicity of various extracts of Cassia sophera in laboratory rats. A methanol extract showed significant diuretic effect with notable increase in rates of water and sodium excretion. An ethanolic extract showed significant laxative effect in a dose dependent manner. Study also showed C. sophera to be safe and failed to exhibit toxicity in the rodent model. (19)
• Anti-Inflammatory / Aerial Parts: Study evaluated an alcoholic extract of aerial parts for anti-inflammatory activity. LD50 for alcoholic and aqueous extracts showed no mortality up to maximum of 2g/kg dose. Both extracts significantly reduced paw edema volume in carrageenan and formalin induced (acute) paw edema model in rats. (see constituents above) (20)
• Antioxidant / Anti-Inflammatory / Analgesic: Study evaluated various fractions of CS for antioxidant (DPPH, reducing power, hydroxyl radical scavenging), anti-inflammatory (carrageenan induced edema), analgesic (acetic acid induced writhing) activities. An ethanol fraction showed concentration dependent reducing power. All fractions showed significant (p<0.05) dose dependent anti-inflammatory activity with the ethanol fraction showing the highest reduction of paw edema and also the activity against acetic acid induced writhing. Results suggest substance like flavonoids which modulate oxidative stress may contribute to the activities. (21)
• Larvicidal / Seed Coat: Study evaluated the larvicidal activity of crude and ethyl acetate extracts of matured seed coat of C. sophera against Culex quinquefasciatus. All graded concentrations from 0.6% to 1.0% showed significant (p<0.05) larval mortality correlating with extracts concentration. (see constituents above) (22)

Results showed significant reduction in elevated glycosylated haemoglobin and increased insulin level. Further study showed the extract stimulated insulin secretion from isolated islets. Effect was dose dependent and the increased insulin secretion was independent of K-ATP channels of the ß-cells. (26)
• Enzyme Inhibitory Effect / Antioxidant: Study evaluated the antioxidant capabilities and inhibitory effect of C. sophera against key enzymes in human pathologies viz. diabetes (α-glucosidase) and neurodegenerative disorders (acetylcholinesterase). Methanol leaf and root extracts showed inhibitory activity against α-glucosidase significantly higher than reference drug acarbose. The antioxidant capacities and anticholinesterase inhibitory activities were less potent than controls. (27)
