PEREIRA-DE-MENEZES-FILHO, Antonio Carlos et al. Phytochemical prospection and biological activities of the floral extract Ceiba pubiflora a. St. - hill. (Malvaceae). Rev Cub Quim [online]. 2022, vol.34, n.2, pp. 324-339.  Epub 14-Jun-2022. ISSN 2224-5421.

The genus Ceiba has species such as Ceiba pubiflora circumscribed in the Malvaceae family where it has annual flowering in the Cerrado domain of Brasil. Flowers of C. pubiflora were collected, and then the extract was produced. Phytochemical analyses, thin-layer chromatography, yield, pH, refractive index and density were performed. Bioactive compounds were determined by the reduction of DPPH free radicals and total phenols. The extract yield was 6,88 %, several classes of compounds present as alkaloids, flavonoids and saponins. The best eluents were acetone and ethyl acetate in thin layer chromatography, the antioxidant activity showed an inhibition concentration (IC50) of 217,4 mg L-1 and total phenolic content of 7,26 mg expressed as gallic acid (GAE 100 g-1).This study allowed, based on the unprecedented results of C. pubiflora, further studies to be carried out, due to the numerous results of great importance, which allow investigating in greater detail the pharmacological, chemical and bioactive characteristics.
