These alkaloids include two tetrahydroprotoberberines, two protoberberines, six aporphines (including 81 and 82), one morphinandienone, five oxoaporphines, seven phenanthrenes
, one spirobenzyl-isoquinoline N-oxide (101), nine aporphine N-oxides (24, 27, 87, 88), (22 and 23 epimers), (89-83), seven benzyltetrahydro-isoquinoline N-oxides (37, 39, 94-98), one benzyl-isoquinoline N-oxide (99), one protopine N-oxide (102), three tetrahydro-protoberberine N-oxides (103-105), three pavine N-oxides (7, 11, 100), and four phenanthrene
N-oxides (83-86) (Wu et al.
There are three peak groups of aromatic hydrocarbons (AHs) in the TICs of Biluo Co oil shale samples: a peak group of naphthalenes and alkyl naphthalenes, a peak group of phenanthrenes
and alkyl phenanthrenes
, and a peak group of aromatic sterenes and other polynuclear aromatic hydrocarbons (PAHs).
They also observed that steroids give rise to substituted phenanthrenes
, and terpenoids produce alkylnaphthalenes.
Oxycodone (14-hydroxy-7,8-dihydrocodeinone) is semisynthetic and it is included in the chemical class of phenanthrenes
Kenplast G low-viscosity mixture of alkyl-ated naphthalenes and phenanthrenes
is an extender for epoxies, a secondary plasticizer for PVC, and a reportedly excellent compati-bilizer for PVC/vinyl acetate combinations.
Over 90 % of the PAH content in these samples consists of three-membered-ring PAHs with high concentrations of phenanthrene
, methylphenanthrenes, and dimethyl-phenanthrenes
The low temperature formation of petroleum favours PAHs with a higher degree of alkylation and PAH profiles that peak at the C2- or C3-substitution: concentrations of C2- and C3-phenanthrenes
in bunker oil were much greater than those of C1-phenanthrene
The experiment demonstrated that the exposure levels of naphthalenes and phenanthrenes
(prevalent in petroleum sources) were below levels where bioaccumulation or bioelimination can be observed in finfish.
ff an oil fingerprint bore the distinctive PAH peaks representing phenanthrenes
and dibenzothiophenes - characteristic of North Slope crude oil --"I assumed it was Exxon Valdez oil:' he says.
Recent ethnopharmacological studies on orchidaceae revealed that a wide range of chemical compounds including alkaloids, flavonoids, glycosides, benzyl derivatives, phenanthrenes
, terpenoids etc.
Triaromatics in aromatic fraction are mainly composed of phenanthrene
and C1-C5-alkylated phenanthrenes
Kenplast G low-viscosity mixture of alkylated naphthalenes and phenanthrenes
is an extender for epoxies, a secondary plasticizer for PVC, and a reportedly excellent compatibilizer for PVC/vinyl acetate combinations.
