Two new alkaloids from Hornschuchia obliqua.
The stem and roots of Hornschuchia obliqua provided two new alkaloids, 4,5-didehydroguadiscine and demethoxyguadiscine. Four known alkaloids, roemerine, guadiscine, liriodenine and cleistopholine were also isolated. The structures of the novel compounds were elucidated by spectroscopic analysis, including 2D NMR and MS.
