Tertiary Indole Alkaloids from Leaves of Tabernaemontana dichotoma

Abstract
Seven indole alkaloids were isolated and identified from the leaves of Tabernaemontana dichotoma ROXB. The major alkaloids were: perivine, 19-epi-voacristine, 12-methoxy-voaphylline and vobasine. (-)apparicine, 19-epi-iboxygaine and isomethuenine occurred in minor amounts.
