Exploring the Discrepancies in the Biological Activities of Extracts From Guadua angustifolia Var. Bicolor Londono Collected in Two Different Sites.

ABSTRACT: Guadua angustifolia var. bicolor Lodoño is a Colombian bamboo species that has shown promising medicinal properties. This study aims to investigate the differences in the chemical composition and biological activity of extracts from two different populations of G. angustifolia var. bicolor, collected in Bauru and Tatuí, Brazil. The extracts were analyzed using high-performance liquid chromatography-tandem mass spectrometry, and their anti-tyrosinase and antioxidant activities were evaluated using the enzyme tyrosinase and diphenyl-1-picrylhydrazyl, respectively. The crude extract was prepared using a Soxhlet apparatus, followed by a solid-liquid extraction and, finally, a column chromatography. The results showed that the subfractions from the two populations had different chemical composi
