Get PDFNão disponível.A survey for evaluating solasodine content in 5 species of Solanum (S. americanum Mill., S. atropurpureum Schrank, S. ciliatum Lam., S. diflorum Vell, and S. sisymbrifolium Lam.) grown in Rio Grande do Sul was carry out. TLC showed that solasodine is the main compound in the dichlorometane and metanol extracts from the fruits. Amounts of solasodine in ripe fruits were: 1,115%, 0,310% and 0,655% obtained from S. americanum, S. atropurpureum and S. ciliatum respectively; in green pale or green yellowish (= mature fruits) fruits were: from S. americanum 0,025%; from S. atropurpureum 0,125% and from S. ciliatum 2,9%; in yellow or red fruits were: from S. americanum 0,035%; from S. atropurpureum 1,9% and from S. ciliatum 2,09%: No values for solasodine were determined in any fruit of different stages of development for S. diflorum and S. sisymbrifolium
