  The EtOH extract of the leaves of Holarrhena curtisii yielded five new steroidal alkaloids: 17-epiholacurtine (3), 17-epi-N-demethylholacurtine (4), holacurtinol (5), 3α-amino-14β-hydroxypregnan-20-one (7), and 15α- hydroxyholamine (8), in addition to the known compounds, holacurtine (1), N- demethylholacurtine (2); and holamine (6). All eight compounds showed significant cytotoxic and leishmanicidal activities.
