Materials and methods Plant material The caprifig Jrani latex was collected from unripe ined-ible fig fruit from Mesjed Aissa agricultural field located in the central cost of Tunisia in June 2010.

Hevea latex is a biological product of a complex composition. Latex is mainly a long chain of hydrocarbon polymer consisting of cis-14-polyisoproprene. Polychloroprene and carboxylated nitrile latexes are mostly used for manufacturing gloves by a coagulant dipping process.

The major constituents in the latex were 5-Oxohexanenitrile 187 phenol 24-bis 11-dimethylethyl-. Fatty acid protein highest concern in most latex product. Chemically latex consists of rubber resins proteins ash sugar and water.

The chemical analyses of these latices are given in Table I and are typical although the composition of commercial. 1 represent the constituents present in the latex obtained by GCMS analysis. The latex of the opium poppy Papaver somniferum is the source of opium and the alkaloid morphine.

Peplus has been reported to contain nonpolar triterpenoids including lanosterol cycloartenol 24-methylenecycloartanol and an acyclic triterpene alcohol peplusol together with a known diterpenoid 20-deoxyingenol 3-angelate Giner et al 2000.

Earlier we reported that the non-aqueous phase contained mainly mono-terpenes having raw mango aroma Phytochemistry 52 1999 891. However latex that are found in natural rubber usually contain other foreign component as well. The basic components of freshly tapped natural rubber latex other than water which constitutes about.

Lucas on ultraviolet microscopy of latex were carried out on commercial ammonia-preserved plantation latex taken from fresh shipments coming from two suppliers.

Table 1 and Fig. In latex paints the paint itself is in the form of minute droplets in water and water is the thinner. These synthetic latexes are produced by a process known as emulsion polymerization starting from monomers and various ingredients whose chemical nature is described in this article.
