Background: Carissa congesta (CC), Polyalthia longifolia (PL), and Benincasa hispida (BH) are economically important plants. Objective: Current research encompasses identification of quercetin and rutin and their analogues by liquid chromatography‑mass spectroscopy (LC‑MS) from the selected plant species. Materials and Methods: Fresh roots, leaves, and seeds of CC, PL, and BH plants respectively were shade‑dried followed by extraction and elucidation of rutin and quercetin by LC‑MS. Results: Structural elucidation of CC, PL, and BH extracts revealed the presence of flavonoids such as quercetin (m/z 301) and rutin (m/z 610) as the parent ions along with presence of close analogues such as quercetin‑O‑hexoside, Vicenin 2, quercetin‑3‑O‑xyloside/arabinoside, and quercetin‑3‑O‑glucoside were identified as fragments. Conclusions: Thus, CC, PL, and BH extracts revealed the presence of flavonoids belonging to the class of flavonols such as rutin and quercetin.
