title: Studies on the Alkaloids of Rhazya stricta.
abstract: A new strychnos-type alkaloid, bharhingine ( 1), has been isolated from the leaves of RHAZYA STRICTA. Its structure has been assigned on the basis of spectral studies including 2D-NMR measurements. The structure and stereochemistry of another Aspidosperma-type alkaloid, strictanol ( 2) has been investigated by extensive NMR studies including hetero-COSY experiments and NOE difference measurements. Isolation of another strychnos-type alkaloid, vincanicine ( 3), not previously reported from this plant, is also described.
