Abstract:
Two ent-kauranoids were isolated from the ethanol extraction of rhizomes of Canna generalis (Cannaceae), and were purified by various technologies, including silica gel and high performance liquid chromatography, and their structures were determined by modern spectroscopy techniques as (5R,8S,9S,10R,13R)-2-oxo-ent-kaur-15-en-17-oic acid (1) and (4R,5S,8S,9S,10S,13R)-19-hydroxy-ent-kaur-15-en-17-oic acid (2). Compound 1 is a new ent-kauranoid, and compound 2 is obtained from rhizomes of Canna generalis for the first time.
