Study of Bioactive Potential of Parahancornia amapa (Huber) Ducke (Apocinaceae) latex collected in Brazilian Amazon

Abstract

Parahancornia amapa is an Amazonian tree that produces an edible white exudate widely used in folk medicine and food. Studies have found the presence of carbohydrates and bioactive compounds in its composition. The riverside population of the Amazon reports the use of this exudate against respiratory diseases and inflammation. This brief communication aimed to show the bioactive potential of the amapá bitter latex. Samples obtained from four different cities were studied and microbiological, physicochemical, mineral, and bioactive compounds were analyzed (Total Phenolic and antioxidant activity by ORAC and FRAP methods). The results showed relevant physicochemical and mineral composition (Ca, Mg and Zn values suggested by the RDA). Furthermore, we found good antioxidant activity throughout latex. The sample from the city of Cametá-PA showed higher values for Total phenolics, and antioxidant activity ORAC and FRAP, respectively. This study is important due to the interesting composition of Parahancornia amapa, which has the potential to be applied in technological routes in the food area.
