<jats:p>Sparsifol (1), a new stereoisomer of inositol, and proaporphine alkaloid crotsparsidine (2), have been isolated from the EtOH extract of Croton sparsiflorus. Their structures were determined on the basis of <jats:sup>1</jats:sup>H and <jats:sup>13</jats:sup>C NMR spectra, DEPT, COSY, NOESY, HMBC, HMQC, EI-MS, and FAB-MS experiments
