Cotyledonary Senescence of Xanthium strumarium Linn

Botanical Gazette, 1974
Cotyledonary senescence of Xanthium strumarium was delayed by removal of the supracotyledonary shoot, and this delay was accompanied by an increase in dry weight and surface area of cotyledons. Gibberellic acid (GA3) was found to enhance cotyledonary senescence and benzyladenine to retard it.

Isolation and Characterization of a Hypoglycemic Agent from Xanthium strumarium

Journal of Pharmaceutical Sciences, 1974
A compound isolated from seeds of Xanthium strumarium exhibited potent hypoglycemic activity in the rat. Partial characterization of the crystalline compound showed that it contains only carbon, hydrogen, oxygen, and sulfur and that the sulfur appears to be present as the sulfonate group. The agent differs from all compounds previously isolated from X.

In vitro and in vivo antitrypanosomal activity of Xanthium strumarium leaves

Journal of Ethnopharmacology, 1995
Antitrypanosomal activity of crude 50% ethanolic extract of Xanthium strumarium leaves was studied in vitro and in vivo. The extract exhibited trypanocidal activity at all four concentrations tested i.e. 5, 50, 500 and 1000 micrograms/ml, in vitro. In vivo trial revealed that the extract exerted antitrypanosomal effect at dosage of 100, 300 and 1000 mg/
