Hernandulcin is a sweet tasting sesquiterpene that occurs in the Aztec sweet herb ( Lippia dulcis ).

Occurrence

Hernandulcin was isolated as a colorless oily substance from the Aztec sweet herb and named after the Spanish physician Francisco Hernández, who described the Aztec Sweet Herb 1570 first.

Properties

The sweetening power of sucrose hernandulcin compared to 1,250 in a 0.25 - molar solution. The sweet taste is a little less pleasant than that of sucrose, and is accompanied by a bitter aftertaste.

The specific optical rotation of the natural ( )- Hernandulcins is 126 ° (c = 0.113 in ethanol at 22 ° C).

After synthesis of all stereoisomers was determined that only the natural ( )- hernandulcin tastes sweet with (2S, 6S )-configuration. All other non- natural stereoisomers only taste bitter.

Production

Meanwhile, it has succeeded ( )- hernandulcin to synthesize enantiospecific.
