Limonene celery seed

Celery seed Apium graveolens L. 3-Butylphthalide and sedaneno-lide (1.5-11), (+)-limonene (58-79), (3-selinene (5-20)... 

Celery contains 1.5—3.0% volatile oil, primarily containing about 60—70% d-limonene and 10—20% /i-selinene. The characteristic celery odour is thought to be due to oxygenated compounds present in the oil (sedanolide and sedanonic acid anhydride). Essential oil of celery seed is available however, the most common extractive form is the oleoresin, due to its fuller flavour. This product contains 12—16% volatile oil.

The composition of celery seed oil has been reviewed [87-92]. Celery seed is extracted selectively with L.CO2 to give the best olefactory yield of 3%. However, continued extraction with L.CO2 or S.CO2 can yield an extra 10% of seed lipids. These lipids only serve to dilute the active components. The 3% yielded L.CO2 celery oil contains all of the available active celery specific natural chemicals together with the minimum of saturated, stable, low molecular weight non-polar lipids compared to the steam-distilled oil which contains very high levels of Limonene [22, 93, 94]. 

The chief components of the celery leaf oil were limonene, myrcene and cis-ocimene (Bubarova, 1973 Fehr, 1974). The sesquiterpene content of the leaf oil (< 5%) was relatively low compared with that of the fruit oil. The essential oil of leaves contained a higher amount of limonene compared with the roots and a very small amount of carvone (Sipailiene et al., 2005). Studies conducted on the leaf essential oil showed that the matured dry leaf contained essential oil having a composition similar to that of seed oil (Thappa et al., 2003). High... 

Celery is used both as a vegetable and a spice. It has several medicinal uses. It is believed to cure most urinary disorders. It has diuretic properties. It is also commonly used to relieve pain. Limonene is the major volatile compound in both leaf and seed oil. Phthalides, myrcene, pinene, etc., are also present. Higher nitrogen inhibited limonene...
