Any one has chemical analysis of 'Latex' or plant milk, found in many plants.?

Generally laticifers ( latex producers) use the sap as a dumping ground for metabolic byproducts. This can deter herbivores from eating the plant. One purpose of latex in plants is to gum up the mouth parts of their predators. When chewed the sap is produced and exposed to air where it oxidizes into a gluey substance. Other latexes carry toxins. Plants like dandelion milkweed and the euphorbias are all strong latex producers but even romaine lettuce produces some that prevents insect attacks.

All latexes are emulsions of insoluble materials: alkaloids, terpenes, resins, phenolics, proteins, sugars, tannins, oils, and long-chain hydrocarbons. Elastic latex contains the long-chain hydrocarbons.





The poppy's resin contains the alkaloid opium. The latex of plants such as papaya, pineapple and fig, have high levels of cysteine proteinases. Their proteolytic activities that are known to digest nematode cuticles. 57 latex proteins are known allergens causing reactions ranging from mild to severe in the human handlers.Any one has chemical analysis of 'Latex' or plant milk, found in many plants.?
G.G. has a good reply.


In addition to milkweed, dandelion, romaine lettuce,


Sunflower seed plant also contain it.





The Hevea rubber tree in Malaysia


and Guayule Mexican rubber bush,


are the two plant species with


Rubber quality, molecular weight and quantity sufficient for industrial use.





As for chemical analysis,


several groups did analysis on various plants and published.


If I find the articles I'll post it.Any one has chemical analysis of 'Latex' or plant milk, found in many plants.?
what?
