Objective – to evaluate the biochemical composition of plant raw material of species of the Silphium L. genus in M.M. Gryshko National Botanical Garden of the NAS of Ukraine. Material and methods. In this study investigated following species of Silphium genus and one cultivar: S. lacinatum L., S. integrifolium Milchx., S. perfoliatum L., S. perfoliatum L. cv. Kanadchanka, S. scaberrinum Ell., S. trifoliatum L. The content of dry matter and crude fiber were determined according to A.I. Yermakov et al. (1972), the total content of sugars, ascorbic acid and potassium concentration – according to V.P. Krishchenko (1983), the content of carotene – according to B.P. Pleshkov (1985), the content of ash – according to Z.M. Hrycaenko et al. (2003), the content of calcium, phosphorus and protein – according to H.M. Pochinok (1976). Obtained data processed in Data Analysis (Excel 2016). Results. In the period of flowering content of dry matter in raw of species of Silphium L. genus was 21.14–29.02 %, total content of sugars – 3.54–12.17 %, crude fiber – 29.46–48.24 %, ascorbic acid – 77.12–296.35 mg%, carotene – 0.23– 1.54 mg%, protein – 14.18–26.08 %, lipids – 2.34–4.26 %. Content of ash was 3.25–7.82 %, potassium – 0.78–2.18 %, calcium – 1.66–3.07 %, phosphorus – 0.13–0.35 %. The coefficient of correlation between all investigated parameters is determined. Conclusions. Obtained data identified that in M.M. Gryshko National Botanical Garden of the NAS of Ukraine investigated species and cultivar of Silphium genus are rich sources of nutrients. The high content of dry matter and crude fiber, potassium, calcium detected for S. scaberrinum, the content of sugars, ascorbic acid, lipids for S. lacinatum, carotene for S. trifoliatum, protein for S. integrifolium, ash and phosphorus for S. perfoliatum. Taking into account obtained data about biochemical composition, plant raw material of these crops can be competitively capable among other forage crops.
