Sustainable valorization of seeds from eight aquatic plant species as a source of oil and lipophilic bioactive compounds

Potential biomass valorization of aquatic plant seeds eight species was studied. Merremia emarginata (Convolvulaceae), Nelumbo nucifera (Nelumbonaceae), Schoenoplectus articulatus (Cyperaceae), Cleome viscosa (Cleomaceae), Ipomoea purpurea Rorippa palustris (Brassicaceae), Ludwigia parviflora (Onagraceae), and Hygrophila auriculata (Acanthaceae) were investigated for their oil yield lipophilic bioactive compound composition. The ultrasound-assisted extraction followed by GC HPLC analyses applied the determination compounds. ranged from 1.7 to 29.1%, in N. H. auriculata, respectively. studied differed significantly with respect composition fatty acids compounds (statistically assessed). Unsaturated (UFA) predominant group (74–88%) samples. Four mainly comprised γ-tocopherol (88–99%) (M. emarginata, C. viscosa, I. purpurea, L. parviflora), while other four samples dominated γ-tocotrienol (72%) nucifera, β-tocotrienol S. articulates, α- (49% 41%, respectively) R. palustris, α-tocopherol (91%) auriculata. β-Sitosterol main sterol (46–69%) majority species, exception which Δ5-stigmasterol (50%) dominated. Considerable levels campesterol each (13–25%) also recorded. Squalene detected only parviflora. characterized considerable quantities carotenoids, tocochromanols, phytosterols, squalene (0.6–6.9, 51–634, 292–2480, 0–22 mg/100 g oil, respectively). Seeds several can be considered as an alternative source and/or valuable ingredients industrial applications.
