Apricot Prunus armeniaca). Apricot seed oil is used in cosmetics and is available as a speciality oil for food use. It contains oleic (58-74%) and Unoleic acids (20-34%). One study gives values of palmitic 5%, stearic 1%, oleic 66%, and lino-leic acid 29%. With its low content of saturated acids, it shows excellent cold weather stability (71, 72). The fatty acid composition of the phospholipids has been reported (73).

Hydroxycarboxylic acids and 5-hydroxycarboxylic acids occur in the form of corresponding y- and 5-lactones in many fruits, especially apricots and peaches. Many other hydroxy fatty acids are also found in seed oils of plants. For example, (S)-jalapinolic acid (3-28) occurs in lipophilic ester-type dimers of acylated pentasaccharides derived from L-rhamnose in sweet potato Ipomoea batatas, Convolvulaceae), which are known as batatins. (9Z,12S)-12-Hydroxyoctadec-9-enoic (ricinoleic) acid (3-29) occurs in castor oil, where it represents about 90% of the total fatty acids. So-called castor oil is extracted from the seeds of the castor oil plant Ricinus communis) of the Euphorbiaceae family, and is used only for technical purposes as it has purgative properties. 

Traditional Medicine. In traditional Chinese medicine, apricot (P. armeniaca) kernels are used as an antitussive and antiasthmatic and in treating tumors. Apricot tree inner bark in the form of a decoction is used in treating apricot kernel poisoning, reportedly with great success (jiANGSu). Sweet almond seed or seed oil has been used as a folk cancer remedy for bladder, breast, mouth, spleen, and uterine cancers, among others. 

Oil of bitter almonds is obtained from the ketiiels (seeds) of the ordinary blilei almond, P/iiiiii.i. T/iygdahis i.imyguulus commimis), a trse which is cultivated in F.urope, Asia. Northern. Africa, and California.

These herbs are moist in nature and are particularly used for moistening the dryness of the intestines and treating mild constipation. Huo Ma Ren and Yu Li Ren are seeds and contain oil that can moisten the intestines and relieve the dryness. They are often used together to enhance each other s function. Xing Ren is the seed of apricot and has a similar function to the first two herbs. However, it also has a dispersing tendency. As it can ascend the Lung-Qi, it can activate Qi movement in the Large Intestine. 

There are a number of minor oils, all of high value, most of which are marketed mainly either for medical purposes or for their flavour. Olive, evening primrose, borage, fish oils and cocoa butter are described elsewhere. Others include hazelnut, walnut, macadamia, almond, apricot, pumpkin, poppy-seed and rice bran oils. The process of testing for authenticity of these oils should be approached in the same way as for the bulk oils above, i.e. fatty acid profile, sterols, tocopherols and triglyceride composition. However, there is little generally available published material on the ranges of values to be expected... 

Amygdalin is present in bitter almonds, the seeds of Primus dulcis var. amara (DC.) Buchheim, and ripe apricot kernels, Prunus armeniaca L. (Rosaceae). The press cake, which remains after removal of the fatty oils, is macerated with water and left to stand for several hours, after which the essential oil is separated by steam distillation. The crude oil contains 2-4% hydrogen cyanide, which is removed by washing with alkaline solutions of iron(II) salts. Subsequent redistillation yields an oil free from hydrogen cyanide. It is a colorless to slightly yellow liquid with an intense, almond-like, cherry aroma and a slightly astringent, mild taste. 

The apricot flesh is very sweet, with the seed kernels regarded the best part of the fruit, tasting sweet and oily, very much like almonds. (It may be noted that the apricot is of the genus Prunus of the plant family Rosaceae, as are peaches and almonds.) Apricot oil is squeezed out under pressure from the ground flour or meal and looks much like ohve oil. A spoonful may be taken as needed, and the oil is also used for deep-frying. Other uses include external apphcations, and it is also mentioned that the oil will even shine silverware. (The preceding information indicates that the apricot kernels are utilized raw, without roasting.)... 

It is stated that the apricots are eaten fresh or dried, and the seeds are cracked open to yield the almondlike nuts. The dried fruit is sweet and soft, but it does not keep well, though it lasts through the winter. It is also mentioned that the sweet apricot nuts are eaten as is, but the bitter apricot nuts are ground, followed by squeezing out of the highly poisonous apricot oil, which is used for fuel in saucer lamps equipped with a cotton wick. 

Benzaldehyde is nsed as an intermediate in the prodnction of flavoring chemicals, such as cinnamaldehyde, cinnamalalcohol, and amyl- and hexylcinnamaldehyde for perfume, soap, and food flavor synthetic penicillin, ampicillin, and ephedrine and as a raw material for the herbicide Avenge. It occurs in nature in the seeds of almonds, apricots, cherries, and peaches. It occurs in trace amounts in com oil.

Exfoliating scrubs are used to remove dead surface cells and allo w other products, such as essential oils, to penetrate the skin more effectively. These are principally suspensions of some kind of particles that are intended to do the exfoliating. Examples include ground pumice, microbeads, ground nut shells (such as walnut) and ground fruit seeds (such as apricot). Other additives may include oils, salts and scents. Some environmental and health concerns about the use of microscale polystyrene beads as exfoliating agents have been noted in Section 8.6.

The aim of our projeet was to identify and determine the fatty acid content of these oils by means of C H NMR spectroscopy. The C H NMR spectra of locally produced marula, apricot kernel, avocado pear, grape seed, macadamia nut, and mango kernel oils are very similar to those of the well-studied olive oil, we attempted to assign their C H NMR spectra by the method used by Mannina et al. for olive oil (1). Mannina et al aehieved assignment of the C H spectra in part by addition of pure Standard triaeylglyeerols we shall refer to as the standard-addition method. For our locally produced oils we found however, that full assignment of the spectra was... 

These can be, for example, special gourmet oils (almond, apricot, avocado, grape seed, hazelnut, and walnut) or oils used for pharmaceutical and cosmetic applications (corn germ, wheat germ, evening primrose, and borage). If the deoiled residual can also be used for food or cosmetic applications, the economy of the process increases substantially.
