| pubmed-article:8984163 | pubmed:abstractText | Three pigments of the guaiazulene class have been isolated from the gorgonian Calicogorgia granulosa. Structures of these compounds have been determined as guaiazulene, 2,2'- diguaiazulenylmethane, and a new compound, 2,2'-biguaiazulenyl, by combined chemical and spectroscopic methods. 2,2'-Biguaiazulenyl exhibited moderate antimicrobial activity. | lld:pubmed |
