Two new bisbenzylisoquinoline alkaloids, (+)-cocsoline 2'-[beta]-Noxide (49), and (+)-12-0-methylcocsoline 2'-[beta]-N-oxide (50), were isolated from polar fractions of the roots of Anisocycla cymosa, in addition to eight known bisbenzylisoquinoline, aporphine, protoberberine, and phenanthrene
alkaloids (Kanyinda et al.
However, the abundant phenanthrenes
are the precursors of the phenanthrene
series, and retenes or pimanthrenes were derived from higher plants, which contributed to the depositional environment and origin.
Four cases of recurrent pseudo-scarlet fever caused by phenanthrene
alkaloids with a 6-hydroxy group (codeine and morphine).
These crude oil combustion samples displayed the entire distribution of PAHs typical for soot samples, from the three-ring phenanthrene
and anthracene to the seven-ringed coronene.
If one assumes such shallow areas contain a mix of diesel, seep, and ValdezoiI, he says, then one can attribute much of any phenanthrenes
and chrysenes present to seep oil, and much of the dibenzothiophene signature to diesel.
derivatives from the orchid Coelogyne cristata.
Triaromatics in aromatic fraction are mainly composed of phenanthrene
and C1-C5-alkylated phenanthrenes
Common PAHs include phenanthrenes
, fluorenes, naphthalenes, fiuoranthrenes, and pyrenes, many of which are known mutagens and carcinogens (19-22).
Veeraghavan These three well produced monographs, the first on benzo [a] pyrenes and benzo [e] pyrenes, the second on cyclopenta [a] phenanthrenes
and the third on benz [a] anthracenes are companion volumes in the Cambridge Monographs series on cancer research.
the corresponding ratio was found to be 88% and 12%, respectively .
