Abstract. A revision of the Mexican species belonging to tribe Senecioneae chemically studied so far, shows that genera Senecio and Packera (subtribe Senecioninae), Barkleyanthus, Pittocaulon, Psacalium, Telanthophora Tussilagininae) contain pyrrolizidine alkaloids (PAs) eremophilane derivatives as their main secondary metabolites. However, from Roldana Robinsonecio no PAs have been isolated. special case is genus Pseudogynoxys in which neither nor eremophilanes are reported.

Species of genus Sida are used around the world for a large amount therapeutic treatments, including hyperglycemia.α-Glucosidase inhibitors recognized as valuable tools reducing postprandial hyperglycemia by retarding absorption glucose.The effect extracts and isolated compounds S. acuta rhombifolia on inhibition α-glucosidase primary screening antihyperglycemic activity was tested using yeast mammalian α-glucosidases.When acetone showed IC 50 values 8.49 ± 0.66 8.10 0.34 µg mL -1 ,...
