Lime blossom

A new poly(7-oxobomene-5,6-dicarboxylic acid-Wod -norbomene)-coa(cd silica has been synthesized and applied for the separation of flavonoids in model systems and in the extracts of onion, elder flower blossom, lime blossom, St. John s Wort and red wine. Separation was performed in a (150 X 4 mm i.d. particle size 7 /rm) column at room temperature. Flavonoids (quercitrin, myricetin, quercetin, kaempferol and acacetin) were separated with gradient elution water-ACN (20 mmol TFA) from 78 22 to 70 30 v/v in 3min. The flow rate was 2 ml/min. The separation of the standard mixture is shown in Fig. 2.51. It has been stated that the method is rapid, accurate and the MS detection makes possible the reliable identification of flavonoids [153],... 

Odors affect human behavior more than we realize. They are now appreciated as important in human health and disease. Above all, the powerful role of learning is impressive. Odors become associated with pleasant and unpleasant experiences and can retain their hedonic value lifelong. This applies to food, to social and sexual relationships, and to environments such as houses, workplaces, or landscapes. Writers rather than scientists have described such anecdotes. In Remembrances of Things Past, Marcel Proust evoked a flood of childhood memories by the taste of a madeleine dipped in lime-blossom tea. Jean-Paul Sartre tells in his autobiography Les Mots how the halitosis of his grade-school teacher became to him the odor of authority. 

Open chain sesquiterpenes are relatively rare. Farnesol is an example and is an important component of the scent of lily of the valley and lime blossom. It is probably formed from farnesyl pyrophosphate by cleavage of the pyrophosphate group. We shall not give any further consideration to the cyclic sesquiterpenes either except to mention the phytohormone abscisic acid (page 210) as an example. 

CijHjsO, Mr 222.37, colorless oil, bp. 160°C (17.9 - 10 Pa) soluble in ether and THF. It occurs in musk kernels, lime-tree blossoms. Acacia species and in essential oils. On account of its intense odor of lily of the valley it is used in the perfume and soap industries. F. acts as a pheroraone for bumblebees. Furthermore, F. diphosphate is the starting material for the... 

I The color of hydrangea blossoms depends on the pH of the soil in which they are grown. Acidic soil (created by the application of ferrous sulfate, or FeSO ) creates blue blossoms. Alkaline soil (created by the application of lime) creates pink blossoms. 

These are also considered as lemonades (particularly in Europe). The most popular are the cola drinks, which contain extracts from the cola nut Cola nitida) or aromatic extracts from ginger, orange blossoms, carob and tonka beans or lime peels. Caffeine is often added (6.5-25 mg/100 ml). Phosphoric acid is sometimes used as an acidulant (70 mg/100 ml). The sugar content of cola drinks averages 10-11%. The deep-brown color of the drink is adjusted with caramel.
