There is considerable interest in understanding the structural bases for these differences because this information would be very useful in designing steroids and other compounds to selectively regulate the activity of one or more steroid dehydrogenases as a means of treating hormone-responsive diseases. There is precedent for this kind of treatment in the use of licorice extract from the root of the plant Glycyrrhiza glabra [15,27] to treat Addison s disease,... 

Licorice is one of the most widely investigated plant products. Modern chemistry has allowed for the isolation, separation, and characterization of dozens of different compounds found in the root extract. No single component accounts for licorice s distinctive flavor, but anethole comes close. This compound occurs in the anise plant, from which it can be extracted, or it can be synthesized in the laboratory. Candy makers commonly use anethole to impart a licorice flavor to their products, like that black stringy confection. This is why naming the treat licorice is misleading. Even when it is made with real licorice extract, the concentration of licorice compounds is very low. We should be aware of this, because it means that neither the problems nor the potential therapeutic effects that we attribute to real licorice apply to the twists we chew on in movie theaters. Real licorice twists do exist, though — mostly in Europe.

Myopathies can also occur as a result of secondary effects. Hypokalemia has been associated with myopathy. Myopathy has been observed in persons consuming large quantities of licorice extract, in persons taking diuretic and some other medications, and in persons with purgative abuse. 

Increasing research has developed several new noncaloric sweeteners the dihydrochalcone group of disaccharide, glycyrrhizin (licorice extract), especially its ammoniated derivative dulcin (4-ethoxy-phenylurea), the glycoprotein of miracle fruit and a polypeptide from a tropical fruit called the serendipity berry, said to be 3000 times sweeter than sucrose. Aspartame (C14H18N205) has been approved by FDA. 

Before any classic peel, steps must be taken to limit the risk of pigmentary changes. Preparing the skin with tyrosinase inhibitors (hydroquinone, kojic acid, azelaic acid, arbutin, Morus Alba, licorice extracts, etc.) is especially recommended to curb the enthusiasm that certain melanocytes have for converting tyrosine into melanin. Preventive measures should begin 3-4 weeks before a medium or deep peel.

Recently, the application of the microemulsion as an eluent in the high-performance thin layer chromatography (HPTLC) has also been described [ 163]. Microemulsions were used as an eluent for the fingerprinting of licorice extract. As proposed earlier, the microemulsion resulted in much better resolution of the components present in the herbal extract as compared to the conventional eluent. This approach would be very useful in the standardisation of the herbal extracts which often consist of a vast number of components with diverse chemical nature. 

The development of the low-tar cigarette required enrichment of smoke flavors in order to make the product acceptable to the consumer. The flavor is enhanced by addition of undescribed materials that may include concentrates of flavor precursors obtained from tobacco, licorice, extracts from other plants, or semisynthetic or fully synthetic flavor components. Because these additives have not been identified, no...

The LD50 of an orally administered licorice extract (53% glycyrrhizin) is 18 g/kg in male rats and 14.2 g/kg in female rats. In mice, the LD50 is greater than 7.5 g/kg (Komiyama et al. 1977).
