The most common types are
anthracene (C14H10, decay time 30 ns), stilbene (C14H12, 4.5 ns decay time), and naphthalene (C10H8, few ns decay time).
Synthesis of PS-co-TMI Containing
Anthracene Moieties
"Dibenzo (a,h)
anthracene, was above, as were the total aliphatics, arsenic, chromium and nickel.
trilobata revealed the presence of phenolic compounds,
anthracene derivatives, and mono-, sesqui-, and diterpenes (Table 1).
7, 12 dimethylbenz (a)
anthracene (DMBA) is among those PAH compounds and known to cause tumor formation in various tissues in both human and animals.
Like fluorene, naphthalene and
anthracene were also present in all the vegetables but their concentration was not very high (6.89+-0.03 ug/kg for naphthalene and 2.18+-0.01 for
anthracene).
Antigenotoxic effect of ferulic acid in 7,12-dimethyl benz(a)
anthracene (DMBA) induced genotoxicity.
The mean concentration of dibenzo(a,h)
anthracene was found to be highest among all PAHs i.e., 123.370 ng/[m.sup.3] with 10.660 ng/[m.sup.3] and 236.080 ng/[m.sup.3], mean, minimum and maximum concentration, respectively.
Polycyclic aromatic hydrocarbons (PAHs): Naphthalene, acenaphthylene, acenaphthene, phenanthrene, fluorene,
anthracene, pyrene, chrysene (internal standard (i.s)), benzo(a)anthracene, fluoranthene, benzo(b)fluoranthene, benzo(k)fluoranthene, benzo(a)pyrene, benzo(g,h,i)perylene, indeno(1,2,3-cd)pyrene and dibenzo(a,h)anthracene.
A total of 14 classes of secondary metabolites were investigated, viz., alkaloids, anthocyanins, anthraquinones, flavonoids, coumarins,
anthracene derivatives, lignans, mono-, sesqui-, and diterpenes, naphthoquinones, saponins, water-soluble tannins, condensed tannins, xanthines, triperpenes and steroids.
