Poppy oil

Evaluating the P/S ratio requires particular care first, because of the presence of mixtures of more than one binder, such as egg and oil in tempera grassa secondly, due to the presence of waxes, and in particular beeswax, which has been widely used as a coating and restoration material and thirdly, due to the contribution of FAs from other sources such as fouling or micro-organisms, which can considerably alter the P/S values from those expected for reference materials. For instance, because the ratio for walnut oil falls between the value of linseed oil, poppy oil and egg lipids, using the P/S ratio it is not possible to differentiate between pure walnut oil, and mixtures of linseed and poppy oil or egg.

If cither colors are required—as red, for example— the fabrio should bo coated with gutta-percha and vermilion. Take one pound of any oil-varnish, or pale linseed, nut, Or poppy oil, previously made drying by any of the ordinary methods, and three ounces of crimson lake grind them well together, and coat the fabric, with a thin layer. If the fabric has been embossed or corked to imitate morocco leather, the result will not be a bad imitation of that article. Of course, any tinge may be produced by a similar process. 

Spirit of turpentine is often used to cheapen the strong-scented attars, such for example as the attar of lavender. Mebo has proposed an excellent method for its detection. It consists in placing one drachm of the attar with an equal volume of oil of poppy in a test-tube, and heating them in a water bath. If the attar does not contain spirit of turpentine, the mixture remains turbid but if, on the contrary, it be present, the poppy oil. is dissolved, and the menstruum becomes clear.. 

Marseilles Soap.—This variety of soap is produced by the saponification of olive oil alone. The process does not materially differ from that described for white soap. Tho duration of the operation is longer or shorter according to the quality of the oil. Some manufacturers use, in the fabrication of this soap, a certain proportion of poppy oil with the olive oil and the addition is rather beneficial than otherwise, as the soap produced is less hard, and consequently more easily applicable to detergent purposes. It is at present manufactured on a considerable scale in this country. 

The best oil for oil paints is cold pressed linseed oil. Poppy oil can be added to the linseed oil to smooth out stringy or sticky paints. The poppy oil should be 20% of the total oil content. 

In relation to Distylium factors research in Distylium racemosum leaves, Prof. Munakata has further studied the provisionally named " Corn factor " from corn germ oil 4). He has examined many plant oils in an effort to obtain a better source of novel plant growth regulators, including coconut oil, corn germ oil, cotton seed oil, linseed oil, olive oil, peanut oil, poppy oil, rape oil, sesame oil, soya oil, and turpentine oil, and found that corn germ oil showed a most remarkable activity in the LJT.

These two acids occur widely in the form of glycerides in vegetable oils such as linseed, sesame and poppy oils. Linoleic acid has two double bonds within the alkyl chain, where linolenic acid has three. 

Poppy Capsules, Poppy heads. Fully grown, dried capsules of Papover somntferum L., Papovemceae. Habit. Europe, Asia. Constit. Capsules 0.15-0.5% morphine and small amounts of other opium alkaloids. Seed Fixed oil (poppy oil), albuminoids. 

Poppy Oil. Poppy -seed oil. Expressed from poppy seeds. Contains no morphine or other opium alkaloids. 

The copolymerization reaction between VAc and poppy oil was performed under the same reaction conditions as used for walnut oil. A white soUd was obtained with a 58.7% yield. The product was characterized by DSC, GPC (Table 4) and H-NMR (Table 1). 

In the H-NMR spectrum, signals of PVAc and poppy oil were present, whereas signals attributable to formation of the VAc/poppy oil copolymer (Table 1) were not identified. Therefore, a homopolymer or a copolymer containing a very low amount of triglycerides were formed in this reaction. 

Poppy oil, as walnut oil, contains a very low amount of linoleiuc chains and the C=C double bonds present in Unoleic and oleic acyl groups have a lower reactivity than the terminal C=C double bond of linolenic fragment. 

Signals attributable to the copolymer formation were not identified for the reaction between VAc and poppy oil, whereas in the presence of walnut oil these signals were identified with lower intensities. 

Besides olive-oil, the earth-nut, sesame, linseed, coleseed, and black garden poppy-oils, greases, tallows, eio. are also used in the fabrication of marbled soaps but the soap resulting from these different combinations of oily and fatty makers, while being of good quality, cannot be compart to those obtained by the direct saponification of olive-oiL The latter are always denser, firmer, and finer. 

Poppy Oil is very rich in linoleic acid (Table 14.11). The cold-pressed oil from flawless seeds is colorless to fight yellow and can be used directly as an edible oil.
