Large-scale purification of pachydictyol A from the brown alga Dictyota dichotoma obtained from algal wash and evaluation of its antifouling activity against the freshwater mollusk Limnoperna fortunei
A scalable procedure was developed for the extraction and purification of pachydictyol A, the main diterpenoid isolated from the brown alga Dictyota dichotoma. The organic extract of this species is a complex mixture of a large variety of diterpenes, and in this work, the protocol was employed succe...
