A new stimulant composition of brain activity based on core eburnamenine alkaloids and their methods of preparation.

摘要

The present invention is based on the discovery of the potent action that certain alcaloids with an eburnamenine nucleus have when they are administered in association with compounds having a xantine structure. A synergic potent action in the cognoscitive capacity is obtained and, consequently the cerebral activity is reinforced in general in the short and long term following the oral administration of the patented composition. The disclosed composition contains quantities comprised between 0.5 and 10 mg of alcaloids or extract of alcaloids of the eburnamenine type per 100 ml of beverage of cola, lemon, cocoa, ginseng, tonic water, coffee or any other beverage obtained from extracts, in quantities comprised between 0.4 and 30 mg of alcaloids or extracts, of alcaloids of the eburnamenine type per each 5-20 g of dry, semi-dry or wet extract of coffee, cola, cocoa, tea, ginseng, tonic water or any other extract for beverages.
