Comparative Transcriptome Analyses of Different Orthosiphon aristatus Tissues Reveal Differentially Expressed Genes Associated with Flavonoid Biosynthesis

Our study incorporates a meticulous comparative transcriptome analysis across the root, stem, and leaf tissues of O. aristatus. We paired this approach with high-performance liquid chromatography (HPLC) to quantify the flavonoids, unveiling a notably higher flavone content in the roots and leaves when compared to the stems. This suggests a potentially valuable pharmacological aspect of the roots that has been understudied.
