Isolation and Characterization of Cyclic C<sub>33</sub> Botryococcenes and a Trimethylsqualene Isomer from <i>Botryococcus braunii</i> Race B
Three cyclic C<sub>33</sub> botryococcenes
and one new trimethylsqualene
isomer were isolated from the B race, Showa (Berkeley) strain of <i>Botryococcus braunii</i>, which is known to produce large amounts
of isoprenoid hydrocarbons ranging in carbon number from 30 to 34.
Their purity was determined by GC-MS, and structures were characterized
by 1D and 2D NMR. One of these molecules, cyclic C<sub>33</sub>-1
botryococcene (<b>5</b>), has an unusual connection of a methylenecyclohexane
ring to the molecule backbone not seen before in botryococcenes. This
report further adds to our knowledge of the wide range of isoprenoid
hydrocarbon structures produced by <i>B. braunii</i>
