Kunth is a herb well-known for its secondary metabolites (SM) with biological potential. In this study, the variations in the SM of<jats:italic>P<\/jats:italic>.<jats:italic>pellucida<\/jats:italic>during association with rhizobacteria were evaluated. Plants were inoculated with<jats:italic>Enterobacter asburiae<\/jats:italic>and<jats:italic>Klebsiella variicola<\/jats:italic>, which were identified by sequencing of the 16S rRNA gene. The data were evaluated at 7, 21, and 30-day post inoculation (dpi). Plant-bacteria symbiosis improved plant growth and weight. Total phenolic content and phenylalanine ammonia lyase enzyme activity had a significant increase mainly at 30 dpi.<jats:italic>P<\/jats:italic>.<jats:italic>pellucida<\/jats:italic>was mainly composed of phenylpropanoids (37.30\u201352.28%) and sesquiterpene hydrocarbons (39.28\u201349.42%). The phenylpropanoid derivative 2,4,5-trimethoxy-styrene (ArC2), the sesquiterpene hydrocarbon ishwarane, and the phenylpropanoid dillapiole were the major compounds. Principal component analysis (PCA) of the classes and compounds \u2265 2.0% indicated that plants colonized by<jats:italic>E<\/jats:italic>.<jats:italic>asburiae<\/jats:italic>had a reduction in the content of sesquiterpene hydrocarbons and an increase in phenylpropanoids and derivatives. Plants treated with this bacterium also had an increase in the content of 2,4,5-trimethoxystyrene at 30 dpi. Plants inoculated with<jats:italic>K<\/jats:italic>.<jats:italic>variicola<\/jats:italic>had significant increases only in the content of the classes monoterpene hydrocarbons and \u2018other compounds\u2019 (hydrocarbons, esters, ketones, etc.).
