To determine very small amounts of in situ forming compatibilizers, MAMA-containing anthracene
moieties was introduced into PS-co-TMI chain to get fluorescent-labeled compatibilizer [28-30].
Terpenes exhibit antinociceptive, anti-inflammatory, and antimicrobial properties (SARTORI, 2005), and anthracene
derivatives, the presence of which has not been reported in this species to date, exhibit astringent activity (SOUSA et al., 2003).
On the other hand, naphthalene, acenaphthene, fluorene, anthracene
, pyrene, and benzo(g,h,i)perylene were not detected in milk samples during both periods.
Among all, anthracene
was higher in all vegetables.
procera: Calotropis procera, DMBA: 7,12-dimethylbenz[a] anthracene
. SD: Standard deviation, MnPCEs: Micronuclei in polychromatic erythrocytes
Several works have verified that benzo[a]anthracene, benzo[a]pyrene and anthracene
are produced by photolysis in the environment at extremely quicker rates.
Naphthalene, acenaphthene, phenanthrene, fluorine, anthracene
, fluoranthene, benzo(a)anthracene and benzo(b)fluoranthene were detected and ranged between 0.05 [micro]g/l and 0.71 [micro]g/l.
These effects can be attributed to the presence of substantial and possible synergies of the chemical components viz., anthraquinones, coumarins, anthracene
derivatives, mono-, sesqui- and diterpenes, triterpenes and steroids, as well as water-soluble tannins.
The main concern related to the presence of PAHs in the environment is ascribed to their toxic potential, such as anthracene
(AN), which has exhibited a high acute phototoxicity, and carcinogenic, mutagenic and teratogenic characteristics, like benzo[a]pyrene (BaP) (Rubio-Clemente et al.
The signals for the anthracene
protons (AnthH) of P-12 and P-13 are found in the expected region of the spectra [20, 25].

The highlighted compounds determined include various cinnamic acids and their derivatives, chromones, anthracene
compounds, and flavonoids, some of which have been reported previously in Aloe species.
