Plant derived natural products are of great interest due to their diversity in modern drug discovery. Sarcococca saligna has been used for the treatment of different diseases. The present study was aimed at isolating phytochemical constituents including Alkaloid-C (1), Dictyophlebine (2),
Sarcorusones A-D (1-4), four new androstane (C19-steroid) derivatives were characterized from Sarcococca ruscifolia along with five known compounds. Their structures were elucidated on the basis of extensive MS and NMR spectroscopic analysis. All the new structures share common 14-hydroxyl and
Three new steroidal alkaloids with an unusual 3α tigloylamide group, named sarchookloides A⁻C (1⁻3), were isolated along with four known compounds (4⁻7) from the roots of Sarcococca hookeriana. Their structures and relative configuration were elucidated on the basis of spectroscopic methods
Two new steroidal alkaloids, named hookerianine A (1) and hookerianine B (2) were isolated from the stems and roots of Sarcococca hookeriana Baill., along with two known compounds, sarcorucinine G (3) and epipachysamine D (4). On the basis of spectroscopic methods
