Study Findings
• Antibacterial: Study yielded tetratriacontanol, tetratriacontyl hexadecanoate and a new 2-tritriacontylchromone; two of them exhibited significant antibacterial activity.
• Antiinflammatory: Study evaluated the anti-inflammatory activity of aqueous extracts and steroidal sapogenins of Agave americana. Extracts showed good antiinflammatory activity.
• Cytotoxic activity: A new steroidal saponin from the leaves of Agave americana: Study isolated a new bisdesmosidic spirostanol saponin along with three known saponins. Hecogenin tetraglycoside showed cytotoxic activity against HL-60 human promyelocytic leukemia cells.

Caution !
• Contact Dermatitis
– The sap of Agave americana contains calcium oxalate crystals, acrid oils, saponins, among other compounds. Despite the known irritants, dermatitis is only rarely reported. (Source)
– A report of 12 cases of contact dermatitis secondary to intentional exposure in soldiers seeking sick leave. (Source)
