Phytochemical studies of the leaves and rhizomes of Paraboea pa niculata (Gesneriaceae) are reported for the first time. Three phenylethanoid glycosides were isolated and characterized as 3,4-dihydroxyphenethyl-(3″- O-β-D-apiofuranosyl)- β-D-glucopyranoside, calceoralarioside E, and acteoside. These isolates exhibited weak cytotoxic activity against the K-562 cell line with a 50% of cell killing rate of 40.18 μM, 27.05 μM, and 27.24 μM, respectively. In the DPPH free radical scavenging assay, their IC50 values were determined as 75.89 μM, 25.00 μM, and 26.04 μM, respectively.
