Proximate analysis and GC-MS phytochemical profiling of aqueous extracts of , a plant used by the Mbya-Guaraní as a contraceptive.

(Presl) Fée, a traditional contraceptive in Mbya culture, lacks scientific scrutiny regarding its chemical composition and contraceptive efficacy. Employing X-ray fluorescence, Fourier-transform infrared spectroscopy, and thermal analysis, we explored the plant's organs. Multielemental analysis excluded toxic elements.

Phytochemical study of ' ( (Mart.) Mattos) and ( Mart.) extracts.

This study explores the phytochemical composition of leaf extracts from (Mart.) Mattos and Mart., used in a contraceptive decoction by Mbya-Guarani women.
