N2 - Three new phenolic glycosides (1–3) together with nine known ones were isolated from the roots of Tecoma mollis using DPPH radical scavenging bioassay-guided chromatographic separation. The structures of the new compounds were established using extensive spectroscopic data and HR-MS. The antioxidant, COX-2 inhibition, and cytotoxic activities were evaluated for the isolated compounds. Compound 4 displayed the strongest radical scavenging activity relative to ascorbic acid with IC50 8.7 μM. Compounds 5, 6, and 10 showed promising COX-2 inhibitory action, IC50 values of 11.3 μM, 9.4 μM, and 13.4 μM, respectively. All compounds exhibited weak cytotoxic activity against Hela and A549 cancer cell lines.
