Senna reticulata, the mangerioba grande or maria mole in Portuguese, is a pioneer tree species found on highly fertile floodplains in South America.

It has some medicinal uses, but is regarded by farmers as a noxious weed, named matapasto (meadow killer) due to its ability to grow fast and outshade neighbouring plants.

1,3,8-Trihydroxyanthraquinone is an organic compound found in alcoholic extracts of the wood of the plant.

The extract also contains, among other products chrysophanol (1,8-dihydroxy-3-methylanthraquinone), physcion (1,8-dihydroxy-3-methyl-6-methoxyanthraquinone), aloe-emodin (3-carbinol-1,8-dihydroxyanthraquinone), lunatin (3-methoxy-1,6,8-trihydroxyanthraquinone), emodin (6-methyl-1,3,8-trihydroxyanthraquinone), and chrysophanol-10,10'-bianthrone.

[4] Senna reticulata has a "unique capacity to colonize open areas".
