Abstract

Two new isoquinoline alkaloids, cryptowrayines A (1) and B (2), along with one known pavine alkaloid (-)-12-hydroxyeschscholtzidine (3), were isolated from the twigs of Cryptocarya wrayi. The structures of new compounds were elucidated by extensive spectroscopic data analysis and electronic circular dichroism (ECD) calculations. Both compounds 1 and 2 exhibited moderate quinone reductase inducing activity in Hepa 1c1c7 cells. • Two new isoquinoline alkaloids, cryptowrayines A (1) and B (2), were isolated from the twigs of Cryptocarya wrayi. • Compounds 1 and 2 were elucidated by extensive spectroscopic data analysis and electronic circular dichroism (ECD) calculations. • Both compounds 1 and 2 exhibited moderate quinone reductase inducing activity in Hepa 1c1c7 cells.
