Although C. roseus has become one of the best studied
medicinal plants, primarily at the alkaloids level and the use of
cell suspension cultures for production of natural products, the
characterization of natural products other than alkaloids in this
plant remains extremely scarce. Water extracts of this plant are
consumed for various applications, such as bleeding arresting,
diabetes, fever or rheumatism (4). In addition, the leaves of the
plants were chewed to suppress the sensations of hunger and
fatigue (3).
