Stigmasterol (201), present in A. donax, C. ciliaris and D. bipinnata proved its value as an antiasthmatic agent, with suppressive effects on essential features of allergen-induced asthma (dietary administered in guinea pigs, 10, 50, 100 mg/kg) [122].This compound also has the ability to protect pancreatic β-cells from glucotoxicity during diabetes progression through inhibition of early apoptosis, increasing total insulin and promoting insulin secretion [123]. This evidence concerns the gene INS and asthma.
