Two isolated crystalline solids from the stem of Entada spiralis Ridl.(akar Sintok) = Pemencilan dua jenis pepejal kristal dari batang pokok Entada spiralis (Akar Sintok)

Entada spiralis Ridl. (Leguminosae) is a woody climber which locally known as ‘akar sintok’. The isolation and structure determination of two crystalline solids from active methanol fraction of E. spiralis stem bark had been examined. The structure identification of both solids was based on spectr...
