title: Botryolins A and B, two tetramethylsqualene triethers from the green microalga Botryococcus braunii.
abstract: Two new triterpenoid polyethers with a tetramethylsqualene carbon skeleton, botryolins A and B, have been isolated from the green microalga Botryococcus braunii. Their structures were determined by means of spectral analyses including 2D NMR.
