ABSTRACT The genus Psidium is recognized for its economic value and the species that produce essential oils with notable biological activities. This study investigated characteristics of oil from leaves myrtoides cattleyanum under different drying temperatures. We aimed to understand how temperatures affect yield composition oil, as well activity. obtained P. dried in an oven at 40°C showed highest yields (0.86% 1.07%, respectively). β-caryophyllene was major compound all cattleyanum, except extracted room temperature, where α-bisabolol (14.46%). Different phytotoxic effects were observed using emulsion these bioassays Lactuca sativa Sorghum bicolor, which associated chemical synergy identified compounds. temperature both greater activity bioassays. Thus, optimizing conditions maximize compounds important step developing environmentally friendly natural agrochemicals.
