N2  - (-)-Phyllochrysine (1), (-)-securinine (2) and a new alkaloid (+)-15&#945;-methoxy-14,15-dihydrophyllochrysine (3) have been isolated from both the bark and roots of Margaritaria  indica ( Dalz .) G. L. Webster. The structure and absolute configuration of (3) follow from its spectroscopic properties and its synthesis from (-)- phyllochrysine (1) as well as from the crystal structure of its hydrobromide, obtained by X-ray diffraction. Diffractometer data at 295 K were refined by least-squares techniques to a residual of 0.053 (991 'observed' reflections). Crystals of 15&#945;-methoxy-14,15-dihydrophyllochrysine hydrobromide are orthorhombic, P212121, a 14.324(3), b 14.194(3), c 7.240(2)&#506;, Z 4.
