    Author: Mukhtar MR, Hadi AH, Rondeau D, Richomme P, Litaudon M, Mustafa MR, Awang K.
    Journal: Nat Prod Res; 2008; 22(11):921-6. PubMed ID: 18629705.
    Abstract:
    The phytochemical study of the bark of Malaysian Phoebe scortechinii (Lauraceae) has resulted in the isolation and identification of two new proaporphine alkaloids; (+)-scortechiniine A (1) and (+)-scortechiniine B (2) together with two known proaporphines; (-)-hexahydromecambrine A (3), (-)-norhexahydromecambrine A (4), and one aporphine; norboldine (5). Structural elucidations of these alkaloids were performed using spectroscopic methods especially 1D and 2D (1)H and (13)C NMR.
