Proanthocyanidins (PAs) in sainfoin (Onobrychis viciifolia Scop.) are of interest to ameliorate the sustainability livestock production. However, forage yield and PA concentrations, as well their composition, require optimization. Individual plants 27 accessions from four continents were analyzed with LC-ESI-QqQ-MS/MS for concentrations simple phenolic compounds. Large variability existed (23.0-47.5 mg g(-1) leaf dry matter (DM)), share prodelphinidins (79-96%), mean degree polymerization (11-14) among, but also within, accessions. PAs mainly located leaves (26.8 DM), whereas stems had less (7.8 DM). Overall, high-yielding lower (R(2) = 0.16, P < 0.001) fewer 0.66, 0.001). results show that these two trade-offs between bioactive can be overcome.
