Tillandsia L. genus comprises 649 species, with different uses at different times. T. usneoides L. uses are reported since the late- archaic and pre-Columbian cultures. In XIX-XX centuries, T. usneoides was used in some manufactured products, as polish and packing fruit. Tillandsia has a favorable reputa...

Comparison of the phytochemical profiles of five native plant species in two different forest formations

Braz. j. biol; 79 (2), 2019
Abstract The expression of chemical compounds by individual plants of the same species in different locations may be affected by abiotic factors resulting in differences in the production of allelopathic compounds. The objective of this study was to compare the phytochemical profiles of plant species fr...
