DESCRIPTION

Croton antisyphiliticus is a subshrub that can be recognized by its irregularly serrate leaves with sessile nectary glands along the leaf margin. Due to its wide geographic distribution and its occurrence in different types of habitats, the species has a great morphological variability throughout its range, especially in vegetative characteristics like leaf shape and indumentum density. The species belongs to sect. Geiseleria subsect. Ocalia (Klotzsch 1841: 195) van Ee & Berry (2021: 136) (Riina et al. 2021).

Croton antisyphiliticus is a medicinal plant widely used in the treatment of microbial infections, especially those affecting the genital tract. Crude extract, fractions and pure compound isolated from roots of this species were investigated to validate their antimicrobial activity against Escherichia coli and Staphylococcus aureus. The compound ent-kaur-16-en-18-oic acid was isolated as a major component (0.7% of crude extract), and its MIC value determined against S. aureus (ATCC 6538) was 250 μg/mL. This is the first phytochemical work on the species monitored with antimicrobial assay.
