“…After concentration, the residue was treated with 125 mL of concentrated HCl and refluxed for 14 h. The reaction product was distilled under vacuum and yielded caramel colored myosmine. The physicochemical parameters of the product were in accordance with values reported in the literature: mp, 39-42 °C; UV, λ max 234 nm; IR, 1618 cm -1 (Korte and Schulze-Steinen, 1962); MS, m/z 146, 70% (M + ), m/z 118, 100%, m/z 105, 30%, m/z 78, 20%, m/z 51, 20% (Duffield et al, 1965;Glenn and Edwards, 1978).…”
