Abstract:
The novel substance of the present invention has been given the common or generic name “SUADIN”. It is a terpenoid substance having the chemical structure shown on the accompanying drawing. Saudin occurs naturally in a plant Cluytia richardiana L. Euphorbiaceae, found growing widely and extensively along the mountainous region (3,000 to 4,000 feet above seal level) of western and southern Saudi Arabia. Saudin occurs principally in the foliage of Cluytia-richardiana preferably collected during the flowering season. When administered by injection Saudin produces a significant hypoglycemic effect in a minimal at doses above about 10 mg/kg for the control of hyperglycemia. A dose between about 25 and about 100 mg/kg is effective when administered at intervals of about 2 to about 12 hours in a tissue-compatible liquid. Normal saline solution is a suitable solvent diluent or alternatively aqueous carboxymethylcellulose. Saudin was isolated from the leaves of the toxic plant Cluytia richardiana. The isolation procedure involved petroleum ether (60‒80°C) extraction to give an orange precipitate which was chromatographed on silica gel with ethyl acetate/hexan (1:1) to give saudin in 0.06% yield. Crystallization of I from ethyl acetate-carbon tetrachloride gave crystals melting at 202‒203°C. Saudin is novel and new compound never isolated from any plant in the world. It is available in the pharmacy textbook.
