Abstract. Rauwolfia plants contain alkaloids and constitute one of the important series of drugs of vegetable origin. In recent years, Rauwolfia has been the subject of considerable scientific research, particularly for its applications in medicine. It is an important genus of the family Apocynaceae which is characterized by the presence.

Rauwolfia alkaloids belong to the general class of medicines called antihypertensives. They are used to treat high blood pressure (hypertension). High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly.

Rauwolfia alkaloids are usually used in combination with a diuretic to prevent sodium and water retention. A lower dose is recommended in the elderly or severely debilitated. Doses higher than the recommended dose should be used with caution because of the risk of severe mental depression.

From the dried roots of Rauwolfia serpentina were isolated five new indole alkaloids, Nb-methylajmaline (1), Nb-methylisoajmaline (2), 3-hydroxysarpagine (3), yohimbinic acid (4), isorauhimbinic acid (5), a new iridoid glucoside, 7-epiloganin (6), and a new sucrose derivative, 6‘-O-(3,4,5-trimethoxybenzoyl)glomeratose A (7), together with 20 known compounds.
